2019 ASAS-CSAS Annual Meeting Highlights

by Xuechun Bai

Austin, Texas, is a fantastic place for passionate ASAS and CASA members to feel the heat of summer and devote themselves to research and industry work of animal science. I feel so lucky to have been able to attend such a great conference, meet a great roster of speakers, take part in their research communication, and question a panel of experts. A big Thank You to Livestock Gentec and Dr. Graham Plastow for sending me and granting me a CSAS Graduate Student Travel Award.

There were too many amazing moments and symposia discussing hot topics and advanced research in animal science to share them all here, so be sure to check out all the event materials through the Meeting App.

Dr. Ignacy Misztal (University of Georgia) opened the Breeding and Genetics symposium with a keynote on the current status of genomic selection that has been dramatically simplified by the development of new methodologies, such as ssGBLUP—single-step genomic best linear unbiased prediction. Dr. Tom Lawlor (US Holstein Association), Dr. Egbert Knol (Topigs Norsvin Research Center) and Dr. Dan Moser (Angus Genetics Inc.) gave great talks about the tremendous impact of genomic selection on dairy, swine, and beef industries, respectively, including current achievements, challenges and future directions. Sessions about animal breeding and genetics broached the central question of how genomic selection has changed livestock breeding. Dr. Makram Geha (Corteva Agriscience) shared his research experience on genomic selection and gene editing in plant breeding, which allow us to broaden our horizons and learn advanced methodologies developed in plant science. Dr. Jack Dekkers (Iowa State University) provided an excellent summary of the meeting with an outlook of the future of increasing genetic gain and precision livestock breeding through machine learning, deep learning, and the development of breeding technologies.

The primary topic of the WAAP-CSAS symposium was improving the efficiency of livestock production. Dr. Graham Plastow gave a very inspiring talk about the role of genomics in enhancing efficiency in swine by addressing social and environmental aspects (such as disease and stress), to improve the sustainability of swine production.

Genome editing via CRISPR-Cas was another popular topic that sparked heated discussion. Dr. Kristin Whitworth (University of Missouri) presented exciting results of creating pigs that are fully resistant to PRRSV (porcine reproductive and respiratory syndrome virus) and TEGV (transmissible gastroenteritis virus) through genome editing. (However, they did not succeed with PEDV.**) Accordingly, talks focused on the global regulatory landscape for evaluation of products derived from gene editing and earning public trust in gene editing, which could help researchers, regulators, governments, and consumers to build better communications strategies on the development and application of this technique.

Other breeding and genetics sessions covered many different and exciting topics, such as the use of APY (Algorithm for Proven and Young) in many studies of genomic selection at the University of Georgia; the integration of microbiome information into the studies of meat quality, carcass composition traits, and host responses to PRRSV in swine.

As well, many sessions on animal nutrition, animal behaviour and welfare, animal health and companion animals were available. Taken together, they gave us new insights into animal science, current science and the next steps.

Last but not least, attending was an excellent opportunity to communicate with people from academia and industry, and to receive feedback and constructive criticism on my research during my poster presentation. It was also a great chance to network, share thoughts, and expand my knowledge with other academics and experts.

Rumen microbiome affects feed efficiency and is associated with host genetics in beef cattle

With our global human population continuing to grow, there is increased competition for resources (e.g., land, water, and cereal grains) between people and livestock, especially beef cattle operations. Improving the feed efficiency of cattle would reduce the amount of feed consumed (especially cereals that could feed humans instead) with equal or higher production performance. Improving feed efficiency can also reduce the negative environmental effects (methane emissions and manure) caused by beef cattle operations.

By applying cutting-edge DNA and RNA sequencing technologies, we explored the rumen microbiome of beef cattle from three breeds on the same diet but divergent in feed efficiency [1]. We aimed to evaluate the breed effect on the rumen microbiome and generate a more conclusive understanding of the role of the rumen microbiome in feed efficiency. We observed differences between the rumen microbiomes of different breeds, as well as microbial features that differed between efficient and inefficient steers. These aspects were also specific to each breed, suggesting that interactions between the host breed and the rumen microbiome influence feed efficiency. We conducted a follow-up study [2], surveying a large cohort of beef cattle (n=709) raised under the same farm environment. Multiple factors, including breed, sex, and diet were identified to determine rumen microbiome profiles. We found that ~34% of rumen microorganisms are heritable elements affected by host genetics and genotypes, that are also associated with host feed efficiency traits and rumen metabolic measures. Therefore, cattle may control their rumen microbiome genetically and consequently influence their rumen fermentation and feed efficiency.

The cattle sampled for these papers were part of the Gentec “Kinsella Cattle Project” (Improvement of cow feed efficiency and the production of consistent quality beef using molecular breeding values for RFI and carcass traits). The Kinsella Project enabled the measurement of feed-efficiency and provided the genotypes and pedigree information for the genome-wide association analysis with rumen microbes.

Overall, our findings highlight a potential to manipulate and obtain a desirable and efficient rumen microbiome using genetic selection and breeding. It could be a useful strategy to further improve feed efficiency and optimize rumen fermentation through targeting both cattle and their rumen microbiome.

The work, funded by Alberta Livestock and Meat Agency, Alberta Agriculture and Forestry, NSERC, and an Alberta Innovates-Technology Futures Graduate Student Scholarship, brought together researchers in beef production, rumen microbiology, functional genomics, quantitative and statistical genomics. Notably, Agriculture and Agri-Food Canada scientists Changxi Li and Carolyn Fitzsimmons, both co-located at UAlberta, were essential in providing these elements for Fuyong’s analysis.

“Rumen microbe composition and abundance are novel quantitative traits in beef cattle. Characterizing variations of rumen microbes among animals and estimating their genetic parameters will also allow us to incorporate rumen microbe measurements into a multiple trait selection index to improve beef production efficiency” says Changxi Li.

The EC project on Ruminomics led by Prof. John Wallace in the UK subsequently reported similar results in dairy cattle.

The Gentec team is now investigating the genetic links of rumen microbes with other beef performance traits.

A career well-remembered

Cambridge, UK 1988. Young post-doc Steve Moore stares out of the window at another rainy English day. In front of him, in the journal Nature, is an advert for a job at CSIRO, Australia’s national science agency, in Queensland. The accompanying image shows palm trees….

Steve got the job. Foregoing cancer research and the UK, Steve would remain with cattle for the rest of his career. He spent the next three years at the Rendle Research Laboratory and Belmont Research Station, the premierresearch stationfor the north Australianbeef industry and nicely situated on the aptly-named Tropic of Capricorn. He spent the following nine years in Brisbane, also for CSIRO, researching tropically-adapted animals.

Reorganizations started to feel like a fact of life at CSIRO. Steve no longer saw a future for himself there. Once again, he cracked open Nature, this time seeing an advert for a job in Alberta.

“Canada was spelled out in big letters down the side,” Steve remembers. “I thought I should jump before getting pushed.”

Steve got the job. In a 180-degree switch from the tropics, he found himself in Edmonton, where the temperature “soars” to -40C in winter. The job was Chair of Beef Genomics and the Alberta Bovine Genomics Program (ABGP), an organization he was to set up and run for 12 years at the University of Alberta.

“I remember going down to the Calgary-Airdrie area to look at yearling bulls with cross-breed producers,” says Steve. “We started to walk through the middle of them. I’m sure the guys were testing my mettle. They didn’t know that I’d been working with tropical bulls that are 6 ft at the hump. These bulls looked small in comparison. They parted like the Red Sea as we walked through.”

During that time, the ABGP enjoyed great support from the Government of Alberta, especially Cornelia Kreplin, and eventually morphed into Livestock Gentec, which broadened its mandate to other livestock industries in Alberta. Hence, Graham Plastow’s (a pig expert) appointment as incoming CEO after Steve. While the pig industry is completely integrated, with all sectors cooperating to achieve common goals, the beef industry is quite the opposite, making it very hard to work up and down the value chain. Canada has made significant efforts to change the information flow up and down the value chain, making all sectors better able to meet consumer preferences.

“Establishing Livestock Gentec remains one of the most satisfying parts of my career.,” says Steve. “Gentec is now a world-recognized centre for livestock genomics with links to other groups in Canada such as the University of Guelph, and beyond with groups in the USA and Europe. The best part was the students, who came from all over the world. They have since moved on and established their own careers in industry, government and academia in Canada, the USA, Europe, Asia and Africa.”

Initially, the position was for three years. Eventually, Steve and his family stayed for 12.By that time, he’d done what he set out to achieve, and he was happy to leave the ABGP/Gentec in Graham Plastow’s capable hands while he took on the role of Director, Centre for Animal Science for the Queensland Alliance for Agriculture & Food Innovation. This time, without the assistance of Nature.

Steve maintains his links to Alberta through research collaborations and as a Board member of Delta Genomics, a not-for-profit spin-off from Livestock Gentec serving the Canadian livestock industry. Steve and Fran’s children remain settled in Alberta, resulting in regular commutes across the Pacific.

Seven years later, Steve has once again achieved what he set out to do. This time, though, he decided to retire, although he will maintain his international engagements with the well-deserved new title of Professor Emeritus. And he has other plans.

“We just bought a property on the Gold Coast,” he says. “My next job is to tame it back to civilized state. That should keep me busy for a while.”

ISAG Meeting Highlights

by Elda Dervishi and Jiyuan Li

The 37th International Society for Animal Genetics (ISAG) conference was held in Lleida, Spain from July 7-12, 2019. Over 700 researchers from all over the world attended to present over 600 scientific contributions. Excellent oral presentations and posters demonstrated recent research advances in livestock and companion animal species. Canada was represented by 25 attendees. Among them, postdoctoral fellow Elda Dervishi and PhD student Jiyuan Li represented University of Alberta and Livestock Gentec with three posters.

ISAG had several plenary sessions, poster sessions and workshops. Dr. Yang Li (University of Chicago) proposed a formal model describing how genetic contributions to complex traits can be partitioned into direct effects from “core” genes and indirect effects from “peripheral” genes acting as trans-regulators. This model provides interesting new possibilities to help dissect complex traits in animal science.

A large number of the oral presentations reflected the wide interest in better understanding gene function in animal species and how this can improve different aspects of animal prediction and/or welfare. The Functional Annotation of Animal Genomes (FAANG) initiative investigates genomic functional analyses for cattle, sheep, fish and chicken, which were widely discussed. Dr. Christa Kuhn from the Leibniz Institute for Farm Animal Biology introduced the new EC Horizon 2020 project entitled “BovReg,” which is part of the FAANG initiative. Gentec is a member of BovReg; Elda and Jiyuan participated in the informal team get-together. The latter also participated in a post-conference FAANG workshop on metadata validation and data submission. The instructor emphasized the importance of standardizing and validating data to facilitate effective data sharing among the FAANG community.

Another topic was the potential role of the microbiome and epigenetics for gene editing. This is a “hot area” in animal genomics research. Dr. Luís Montoliu (Campus de Cantoblanco) gave a comprehensive talk on the current situation of genome editing including the tools used and their potential application in animal science.

Whole genome sequencing and RNA-seq are increasingly used in animal genomics research. New sequencing technologies such as ATAC-seq and single-cell RNA-seq have also become more popular together with ChIP-seq for chromatin analysis. These new technologies and analysis methods give us new insights into the function and network of genes and the genome. Again, they are an integral part of FAANG and BovReg.

An unforgettable gala dinner was served in the main building of the Old Cathedral built between 1300-1600, on top of the La Seu Vella mound. ISAG organizers really showed their hospitality. We tasted local cuisine and red wine produced by a local chateau. Everyone enjoyed the authentic Spanish food and the great view.

 

“Attending the conference was a great experience, giving us an opportunity to tell others about our work, to talk with so many excellent researchers from all over the world, to learn about new research going on in the world, to broaden our horizons and keep improving our academic ability,” reported Jiyuan and Elda. “We appreciate that our supervisor, Dr. Graham Plastow, supported our participation.”

21st Century Solutions for Canada’s Dairy Industry

Where once genetic and herd management services to the dairy industry came from separate sources, Lactanet Canada now integrates these services under one organization.

As of June 3, 2019, founding partners of the new Lactanet (Canadian Dairy Network, CanWest DHI and Valacta—the leading dairy herd improvement organizations responsible for genetic evaluations, milk recording and knowledge transfer) can offer access to modern herd management through improved technologies and software and more meaningful data. Not only will these integrated services make life easier for farmers, Lactanet will also offer new services, using the same current resources. These services will be offered before the end of 2020, and include remote electronic collection of on-farm data, a national dairy cattle traceability system and genomic evaluations for feed efficiency,

While the objective in creating the partnership was not to save money (although operational efficiencies are predicted), Lactanet’s Chief Services Officer, Brian Van Doormaal, points out that fees for current services to farmers and the staff delivering them, are not projected to change nor are genetic evaluation services to the industry.

What Lactanet will do is: better position the dairy sector to manage business risk, take advantage of operational synergies and efficiencies, integrate genetics with management services, stimulate innovation of new products and services, and build on the strengths of each partner.

“The sector as a whole will benefit,” says Brian. “We’ll be able to help farmers tackle the challenges of the Canadian dairy industry, which include lower milk prices, increased farm debt load and rising interest rates.”

Lactanet’s governance structure is designed to reflect the three founding organizations, and focus on services to Canadian producers: every member of the Board is a dairy farmer. Three additional important industry partners have a producer appointment to Lactanet: Dairy Farmers of Canada, Semex Alliance and Holstein Canada.

“Holstein represents over 90% of all dairy cows in Canada,” explains Brian. “And Semex is the largest Canadian farmer-owned A.I. company with national reach. Dairy Farmers of Canada is the national body that represents all licensed producers from coast to coast. In this way, the Lactanet Board covers the vast majority of services to farmers. As well, working with a Board of nine producers, with the ability to name two additional external directors, allows us to be more nimble in these early stages and ensure success. The Lactanet governance model is scalable, if needed, as the industry decides how to best meet the needs of dairy farmers and remain globally competitive.”

Innovation Collage from China

Gentec’s former Director of Knowledge Translation, Dawn Trautman, spent 12 days in China at the beginning of May, marvelling at its contradictions and potential with her MBA program group.

She walked us through her photo album and shared her insights on this global powerhouse.

Hanergy
Hanergy is one of the largest solar manufacturers in the world, specializing in thin film and thin-film solar cell research. It has R&D centres in Beijing, Sichuan, Silicon Valley of the US, and Uppsala, Sweden.

“The technology is getting better,” says Dawn. “Hanergy is proud of the 17-18% efficiency of its solar panel glass windows. The opacity is gone. Now you just see a bit of a wave.”

“The demonstration products in the showrooms got more and more impressive as we progressed. Anything you can think of to put a solar panel on—they’ve done it. Umbrellas… Coffee shop tables… Sidewalks… Drones… Anything. You didn’t know you needed this power until you have it there. The bike has a solar panel in the basket that powers the payment system for a bike-share program. Panels on the back of a jacket power heating elements. It’s all ingenious.”


Hanergy has applied for almost 1,000 patents in new energy, of which 60% are invention patents (including core patents from the acquired overseas companies). It has also been the chief developer or involved in the development of over 10 national and industry standards on solar energy.

“Very impressive solar cars,” says Dawn. “Flashy—but not available for purchase yet.”

Belt and Road Initiative

The former home of Dr. Li Ruohong, President of China World Peace Foundation (CWPF) and Beijing International Peace Culture Foundation (BJIPCF) converted into a ‘museum’ and hosting residence for delegations. Dr. Ruohong is involved in the Belt and Road Initiative; an ambitious endeavour for linking China with neighbouring and distant regions, physically and with policy and trade coordination. It will put China at the centre of international trade with the end result to ‘open up the world’ to globalization and international cooperation.

In 2018, Gentec CEO Graham Plastow attended a conference on the Belt and Road Initiative on behalf of UAlberta. Gentec’s linkages with the China Agricultural University, Zheijiang University, Huazhong Agricultural University and others as well as exchanges of personnel have contributed to vibrant relationships for the benefit of science and the two countries. Notably, former Gentec professor Zhiquan Wang is now helping the Guangxi Yangxiang Co Ltd develop its pig genetics program, including using new technologies such as facial recognition.

As well, UAlberta itself has facilitated linkages with China, notably when Dr. Lap-Chee Tsui, President and Vice-chancellor of the University of Hong Kong, visited the University in March 2015 for roundtable event called International Collaborations with Scientists and Educators in China. Another more recent event was the latest Canada China meeting regarding Science, Technology and Innovation (STI) Collaboration Projects through Global Affairs Canada, which may include a project on beef with Gentec.

“What struck me was that there’s not much influence from the Americas,” continues Dawn. “We have this centralized view of North America but on the global scale, it’s a bit worrying that we seem to be an afterthought. We really need to address how Canada can play a bigger role, especially since we’re Pacific neighbours. Our professor said that another possibility of partnerships with China would be to gain access or facilitate partnerships to other countries.”

Panels like this one record the gender and age of shoppers, how many parking spots are free, etc. so shoppers can decide when to go to avoid the crowds. It also directs heating and cooling from the recorded hotspots.

“This was a bit spooky,” says Dawn. “We couldn’t figure out how they know the age and gender! Maybe through the messaging-social media-mobile payment app, WeChat. And there are cameras everywhere, so as a tourist you feel really safe.”

Shanghai Zhangjiang HiTech Park
This park acts as an incubator for tech companies as well as an accelerator and free-trade zone. Companies there make a video game for hand-and-arm rehab that is being sold in Germany, and other health-related products.

Shanghai Starbucks Reserve Roastery

At 30,000 square feet, this was the largest in the world until a one opened in Tokyo. At $6-7/mug, Starbucks is expensive in China, more of a status symbol.

Contrast and contradiction

“You see what I mean about contradictions?” asks Dawn, speaking of these images. “Shanghai is like any international city. There’s even a French concession area. It didn’t always feel like China, whereas Beijing and the other cities did. China will host the Winter Olympics in 2022 so I think they will reuse the Bird’s Nest.”

“We should be more aware of their development,” she says. “It felt like the future is here, and we’re playing catch up. Obviously, there are still problems, like pollution, but there are trees and tree farms everywhere so they are concerned with the environment. Is it a distraction? Some of the more interesting things in societies are their contradictions. China is both modern and respectful of its traditions, and it seemed there was often structure and chaos at the same time.”

Wind, rain and cows

Robert Mukiibi is finishing up his PhD in bovine quantitative and functional genomics related to feed efficiency. He’s been with Gentec for nearly four years. During that time, he has focused on improving feed efficiency in beef cattle through the genetic selection of more efficient animals using high throughput genomic tools. His research aims to identify genes and gene variants associated with feed efficiency through sequence transcriptomic data analyses of coding and non-coding species of RNA. The information obtained is then used to improve genomic merit estimation for breeding animals. Robert is also involved in imputation of genotypes from low density panels to high density and full sequence genotypes, and genomic prediction for feed efficiency traits in beef cattle.

This is where the Irish angle comes in. Canada and Ireland have common research interests in beef cattle genomics. In 2014, Robert’s supervisor Dr. Changxi Li at Gentec, UAlberta and Dr. Sinead Waters at Teagasc (the Agriculture and Food Development Authority, Ireland) were awarded a Teagasc-UAlberta Walsh Fellowship to work on the project: “DNA-based biomarkers for feed efficiency in beef cattle,” which helped support Robert’s own project: “Quantitative and molecular genetics of feed efficiency traits in Irish and Canadian beef cattle.”

“For my project, we are using the functional information of the bovine genome to improve accuracy,” says Robert. “I perform the gene expression, gene functional characterization analyses and genomic analyses in Canada. In Ireland, I perform the lab work to validate the gene expression results.”

Robert has visited Ireland twice for his project, first in 2016 and again in 2018 with Dr. Li to enhance the joint research activities. During the 2018 visit, the pair presented at the National University of Ireland, Galway, and at Grange(see below). Robert’s Irish co-supervisor, Dr. Waters, is expected to visit Canada as part of the exchange.In 2017, Gentec hosted Teagasc’s Tara Carthy, who was working with Gentec’s Dr. Paul Stothard to identify structural variants in the bovine genome associated with important economic traits.

In Ireland, Robert worked at theAnimal Bioscience Research Centre Grange, one of the world’s leading beef production research facilities, outside a small heritage town called Trim in County Meath.

“Ireland really is as green as they say,” he winces. “It rains several times every day. It’s vital to carry an umbrella but it’s not always useful because of the strong winds.”

Similar to Gentec, the lab experience was all Robert could hope for. Cooperative and collaborative colleagues, unlimited access to lab tools and everything he might need to obtain reliable and reproducible results for the scientific community and industry. While there, Robert expanded on his social experience with visits to the pubs to see live bands, and watching Gaelic football. Such was the warm and welcoming working environment, that fellow students picked Robert up from his lodgings and brought him back—for which he was extremely grateful.

“The bus rarely runs on time and the frequency is very low,” he remembers. “So when it breaks down, I had to wait an hour for the next one.”

In terms of key points that might help other students decide where to study, Robert believes that Canada is a bit more student-friendly than Europe in terms of easily accessible healthcare, availability of student partner employment permits, availability of extra merit-based scholarships and affordable and efficient transportation through student passes. A major difference he highlights is the high cost of student accommodation in Canada compared to Europe.

Robert thanks Dr. Li and Dr. Waters, Teagasc, Alberta Innovates and the Department of Agricultural, Food & Nutritional Science at UAlberta for the wonderful opportunity of the Walsh Fellowship. He is already looking for a postdoc position for the fall.

“I’ve now lived out of my home country, Uganda, for more than 10 years in countries including Egypt for my undergrad, Sweden and the Netherlands for my MSc and now Canada for my PhD. So the next stop can be anywhere in the world. I’m open to suggestions.”

Is there a “beef” with Canada’s new Food Guide?

The 2019 update of Canada’s Food Guide has been out for about a month. In that time, it has been both praised as better reflecting today’s lifestyles and sustainability issues, and reviled as insufficiently reflecting Canada’s demographic diversity.

“Certainly, the new Food Guide has some great concepts,” says Tom Lynch-Staunton, Alberta Beef Producers’ Government Relations and Policy Manager. “The proportions of fruit and veg versus protein and grains… absolutely, that’s appropriate.”

Where the livestock sector differs is that the Guide over-emphasizes plant-based protein—on a plate that’s already three-quarters full of plant-based items.

“We think that could be misguided,” says Tom. “Plant proteins don’t have the same nutritional profile as animal protein. Meat contains all the essential amino acids; plants don’t. Vitamin B12 only comes from animal protein, unless supplemented in other foods. And iron from red meat is much more bioavailable than plant-based iron.”

The beef sector is concerned that animal protein and plant protein are made to look equal. However, certain demographics (children, seniors, pregnant women, athletes, etc.) need extra nutrients that they may be substituting out with plant protein without realizing that they may be inviting deficiencies. Milk is an obvious example.

“If you give your children soy milk instead of cow’s milk, thinking it is the same, they probably won’t grow the same way,” says Tom. “You have to compare the nutrient profile! That’s the missing piece.”

Tom would have preferred the Guide to recognize that milk, meat and eggs are highly nutritious but that if people don’t want to eat them… here (the missing piece, perhaps advice from a dietician) is how to get equivalent nutrition that meets their needs from alternatives. You can’t just tell people to replace meat with lentils and be done with it.”

Alberta Beef Producers isn’t really worried that Canadians will switch to tofu by the thousands and drive it out of business. True, Canadians are eating less beef, but the developing world is increasing its consumption as the quality of life in those countries improves.

Instead, it is positioning beef consumption as a complement to other foods in smaller amounts. A 180-degree shift from the more familiar steak. That might mean adding a few slices of beef to a salad high in Vitamin C to better absorb the iron from the beef, which can increase the bioavailability of the iron from the spinach as well. Alberta Beef Producers is also positioning beef as a nutrient-dense food to those demographics who need the extra nutrients, and trying to reconnect consumers back to where beef comes from… how it’s grown and the environmental benefits of raising livestock, especially on land that is not suitable to grow crops. There are lots of misconceptions out there.

“Of course, we want people to eat beef and drink milk,” says Tom. “There’s an economic value that infers bias. And, of course, we wanted to be consulted on the Guide but Health Canada was trying to keep bias out of the mix. Bottom line? That’s irrelevant. What IS relevant is how the Guide improves the health of Canadians. So the question is: how much (nutritious) meat can you eat to complement other items on the plate. That’s the balance we’d like to see.”

Hands-on practice helps student learning stick

The Ruminant Digestion, Metabolism and Nutrition course at UAlberta benefits from hands-on industry participation

ANSC461/AFNS561 is a “must-have” course for any student wanting to improve their knowledge and understand the principles of ruminant nutrition, digestive physiology and metabolism—and apply this knowledge in commercial dairy and beef operations.

“Industry contribution provides great opportunities for students to better understand the industry and put their skills in practice,” said course co-teacher and Gentec researcher, Dr Ghader Manafiazar.

One beef farm Blindman Beef and Bison Farm (check out the incredible photography) and one dairy farm Tuxedo Farm Ltd kindly volunteered to host the students and provide the required information for them to complete their project.

Blindman Beef and Bison Farm sits beside the Blindman River in the south-central region of Alberta, with about 300 Angus and Beefbooster cow-calf pairs. The farm backgrounds its own calves as a better marketing practice. Assar Grinde, the owner, is highly concerned about and focused on the animals’ welfare, practising antimicrobial stewardship and environmentally sustainability, and having third-party verification for the farm’s practices. Assar shared his pasture management, bale grazing, weaning, and grain processing practices in addition to feed and water analysis with the students.

Tuxedo farms Ltd. is a family owned and operated farm located northeast of Westlock, in North-Central Alberta. Diversification is a major goal. The farm feeds high-quality, home-grown corn, barley and hay to its dairy (337 cows, of which 285 milking cows) and beef herds. Management added 120 free-stalls in 2018, and will add more in coming years. The farm is equipped with advanced technologies, such as Herd Navigator and a body-condition scoring camera. Herd Navigator detects sick animals for treatment and those producing less than 10 L/day to go dry. Nelson Jespersen, the manager, asked his nutritionist, Jamie McAlister, and herd manager, Francis Kavanagh, to participate in our two visits, allowing the students to discuss many aspects of the dairy farm business and management in smaller groups with them.

At the end of the semester, teams of students presented their recommendations to Ghader and the farmers, with an opportunity for discussion and feedback.

“It’s one thing to learn theory in class,” says Ghader. “Learning by doing sticks better. Overall, the students appreciated the opportunity to act as a consultant and put their knowledge into practice.”

Ghader also invited Barry Robinson (a private consultant), Kris Wierenga (regional manager with Shur-Gain feed mills), Myrddin Jespersen (farm owner) and John Stephen (Senior Sales Professional with Elanco) to present on the opportunities and challenges in different segments of the industry. Barry talked about his experience as a nutritionist; Myrddin discussed the opportunities and challenges of owning and managing a dairy, beef and grain farm; John shared his insight about the pharmaceutical industry; and Kris talked about the commercial feed industry. This session encouraged students to look for the opportunities in these sectors and expand their networks.

“It’s important for industry to be part of this course,” says Ghader. “Their contribution allows students to see where they can fit their skills and what other skills they need before entering the workforce.”

One woman’s search for a research home

From the Middle East to Europe and North America, Marzieh Heidaritabar talks to Gentec about the meaning behind international science.

Already, as a thirty-something, Marzieh Heidaritabar has lived in six countries as part of her studies and career. Such is the life of a scientist, these days.

“I always knew I wanted to go abroad for my advanced degrees,” she says. “The level of achievement at European and North American universities is higher than at home.”

Building on a Bachelor’s in her native country, Iran, Marzieh won a European Master of science in Animal Breeding and Genetics (EMABG) scholarship. She spent the first year at the renowned SLU (Swedish University of Agricultural Sciences in Uppsala) and the second at the Norwegian University of Life Science (NMBU) in Sá.

Wageningen University & Research (WUR) (in the Netherlands, where Marzieh completed her PhD in 2016 on genomic selection in egg-laying chickens) is my second home,” she says. “It’s a small—but highly social and connected—society of students. I was never bored.” Then, over to Aarhus University Foulum for a post-doc, where she already knew several researchers from collaborations with Wageningen.

“I was right about the European universities,” she says. “All of these are in small towns where students are the majority of the population. The facilities, computer labs and digital libraries are excellent, so are the teaching and technical support.

As a testament to the connectivity of the European science community, Marzieh didn’t have to learn any languages. With international reputations and a large international student body, almost all MSc courses are taught in English and the townsfolk are keen to practise their own language skills.”

During her PhD, she also spent several months at Iowa State University (ISU) in Ames, USA. “The ISU group is one of the best in quantitative genetics,” she says. “I learned a lot from my supervisors (Jack Dekkers is a long-time Gentec collaborator). People are hard workers and the group is so dynamic. I also met some faculty members and geneticists from other USA universities and companies.”

Then on to Canada. During Marzieh’s PhD, the Dutch company (Hendrix Genetics) that supplied her data also worked with Gentec CEO, Graham Plastow. Throw in some reminders about Gentec over the years through workshops, colleagues, some reading and fellow Iranians, and Marzieh decided to reach out.

Marzieh has been in Canada since late summer 2018. These days, she is working on swine data for the first time (data provided by Hendrix). She is exploring the potential benefits of whole-genome sequence (WGS) data to improve meat and carcass quality traits in genomic selection programs of purebred and crossbred pigs. Incorporating the biological information from WGS into genomic prediction models will lead to a better understanding of the genomic architecture underlying carcass and meat quality in swine.

Of course, there are pros and cons to moving around so much. Marzieh has learned about different research styles, communication styles, PhD content (North Americans expect PhD students to teach and take subject matter courses: not so in Europe), new cultures and lifestyles—an openness that hasn’t been available to her friends who chose to stay home.

“The disadvantage is that I always feel I’m not settled yet,” she says. “There’s a cost to physically moving your life from place to place. And there’s definitely an anxiety at the beginning about not being familiar with new towns, colleagues, culture and research. Special thanks to Dr. Plastow and other people from Gentec who welcomed me warmly so that I felt at home. I am very glad to be a member of Gentec.”

For someone who was raised to be quiet, it’s been a positive learning experience.

“I was shy,” she says. “Too shy to ask my supervisor for help. The student culture in Wageningen helped change that. You either get help or you don’t, but you have to ask! If I hadn’t left Iran, I wouldn’t be the person I am now.”
