Banff Pork Seminar; the experiences and insight from a student presenter

By Teresa Lantz

Every January for the last 14 years, Banff, Alberta plays host to the Banff Pork Seminar (BPS). The Fairmont Banff Springs Conference Centre currently accommodates this event, which brings together a wide array of university students, researchers, industry professionals and producers. This year, over 750 attendees from all over the world took in the sessions, including plenary talks about African Swine Fever, the plant-based alternative protein movement and wild boars in Canada.

The overall program aims to provide practical science with direct applications to the swine industry, ample networking opportunities, and lectures with relevant information for producers, students and researchers. In alignment with this, the BPS runs several competitions within the conference, one of which focuses on the creation and dissemination of new and relevant science by undergraduate and graduate students: the RO Ball Young Scientist award. Students must submit abstracts with their work to a poster competition for evaluation by the BPS awards committee. Four finalists then prepare a 20-minute presentation in addition to a poster to be a part of the ‘Innovators’ lecture series at BPS. This presentation is judged by a panel of industry professionals and researchers, who elect the top two student contenders to win a cash prize. This year, I was honoured to win second place. First place went to Julia Moroni, one of Gentec-associated researcher Mike Dyck’s students.

My poster focused on meat quality, while other topics discussed reproduction, nutrition and behaviour, which offered a well-rounded afternoon of learning. This is standard for BPS, with lectures for all interests, which are repeated (except for the ‘Innovators’) so participants are not limited on the topics they can learn about. Listeners were engaged in every presentation, confirmed by the significant number of questions fielded. To me, this meant each talk was appropriate for the audience. The scope of knowledge provided significant value and an invaluable experience for a young professional hoping to continue a career in this industry. The connections sparked from this opportunity will, I’m sure, prove vital in the coming years.

The BPS also provides excellent experience for young professionals and students in the generous opportunities to network without feeling the weight and awkwardness that traditional networking opportunities often pose. The BPS is friendly, open and personable—an environment sometimes not felt at conferences, particularly for students who may lack networking experience. By providing multiple, bite-sized time-chunks plus coffee and tea, talking to fellow attendees feels much more natural; particularly when you can reference your poster and presentation and take a quick sip before asking for a card. Finding a common connection or discussing the lecture you just listened to simply feels less intimidating!

One of the most interesting things I noted was the support and encouragement given by colleagues and network acquaintances upon learning of the competition—and from the other three finalists. We all were very happy to be sharing our research and this experience with one another. As finalists, we also volunteered during the event, so we spent significant time together. This camaraderie during competition was refreshing and showed a truth of young professionals; we support one another and are excited for our future and that of our peers as we pursue advancement in the Canadian swine industry.

The experiences and opportunities provided by the BPS for me as a graduate student, particularly with plans to defend my thesis shortly and move into industry, are extremely valuable. The connections made, and ability to show my name on this scale to such a variety of industry professionals, and adding this competition and an award to my CV will undoubtedly help in my eventual job search.

I recommend the BPS to all students in the swine industry and to those interested in the animal agriculture industry. The science is relevant and accessible, and the setting is unmatched! For researchers and industry professionals, this conference provides significant networking opportunities for the next generation of students graduating and an opportunity to gather with some of the prominent voices in the industry. Together, students can learn from the previous year and work on the emerging challenges while enjoying some wonderful mountain views. It is an excellent way to kick off the New Year. I hope to see you there in 2021!

Wind, Rain, Cows and now… Fish

In April 2019, we spoke with Gentec PhD student Robert Mukiibi about his experience working with Ireland’s Teagasc on a joint project to find biomarkers for feed efficiency in cattle (read that article here). He concluded that, having already lived in four countries as part of his studies, he was pretty open to any geographical location for pursuing his postdoc.

That location turned out to be Scotland. As of November 2019, Robert is a postdoc at The Roslin Institute, a world-leading institute for animal science research that is part of the University of Edinburgh. While Gentec has many close contacts and collaborations with the institute from which Robert might have benefited, he did this old-school. He applied for the position prior to his graduation from University of Alberta, interviewed, and got the job.

Robert’s research to date has been in beef cattle. At Roslin, he’s working on fish! Specifically, it’s an Aqua FAANG project on improving functional annotation of farmed fish genomes. His part will involve molecular characterization of disease-resistance in farmed seabass using multiple functional genomic tools (genome-wide association studies, coding and non-coding RNAseq analyses, epigenomic analyses and genomic predictions). This functional information will be integrated into genomic prediction models to enhance the genomic prediction accuracy for disease resistance in farmed seabass. The work package is led by Ross Houston, who is also chair of aquaculture genomics at Roslin. The Aqua FAANG project is led by CIGENE in Norway, and includes 24 partners spread over the UK, France, Spain, Italy, Poland, The Netherlands, Greece and Germany.

“I was lucky,” Robert says. “Even though fish are new to me, I am able to carry over my experience and expertise in all the tools, techniques and technologies I learned at Gentec and Tegasc, in particular from the labs of my PhD supervisors Drs. Changxi Li and Sinead Waters. What will be new is working as one of several hundred employees, instead of the smaller groups at Gentec and Teagasc. I am excited to acquire new knowledge of the aquaculture world in Dr. Ross Houston’s lab.”

Another link is with the European FAANG project, BovReg, which includes Kinsella Composite cattle. Common activities, such as bioinformatics are being coordinated across FAANG projects, so Robert may well bump into some of his old friends at project events. (see PAG report).

Just before he arrived in Scotland, Robert’s publication (Liver transcriptome profiling of beef steers with divergent growth rate, feed intake, or metabolic body weight phenotypes), which features his Canadian and Irish supervisors as co-authors) won Editor’s Choice in the Journal of Animal Science. In this study, they employed transcriptomic analyses to identify genes and biological mechanisms associated to feed efficiency component traits in Angus, Charolais, and Kinsella Composite cattle. The study identified key processes related to liver nutrient metabolism (including amino-acid, carbohydrate and lipid metabolism) and immune-related processes related to feed-efficiency traits in beef cattle. In terms of the biological mechanisms, the results showed that underlying functions are largely the same across the three breed populations, however the genes within these functions or processes were majorly breed-specific.

Back in Ireland, Robert was mildly unimpressed by the daily wind and rain. He hasn’t exactly jumped from the frying pan into the fire but Edinburgh—facing the aptly-named North Sea—isn’t known for its palm trees and sunny beaches. We’ll have to wait for his verdict.

Plant and Animal Genome Conference XXVIII Highlights

by Xuechun Bai

The Plant and Animal Genome Conference (PAG), marketed as “the largest ag-genomics meeting in the world” takes place in the middle of January each year in San Diego, California. In the laid-back California atmosphere, San Diego is always a sunny, warm place to defrost from Alberta’s chilly winter. PAG XXVIII, held on January 11-15, 2020, brought together over 3,000 leading scientists, researchers, biologists, bioinformaticians, and industry representatives from around the world who presented their latest contributions and future research. Tianfu Yang (postdoctoral fellow) and I (PhD student) were so excited to represent UAlberta and Gentec at the meeting, and feel on the cutting-edge of genomics. A big Thank You to Gentec and Dr. Graham Plastow for sending us and helping me secure a Graduate Students’ Association Academic Travel Award.

The large crowds and packed schedule at PAG XXVIII covered a range of topics related to the genomes of plants and animals, so be sure to check out all the event materials through the Meeting App.

FAANG Workshop and Updates
FAANG is the Functional Annotation of ANimal Genomes project and works to understand the genotype to phenotype link in domesticated animals. PAG XXVIII provided a great opportunity to foster interactions and collaborations of the FAANG community and to communicate and exchange information regarding their recent FAANG contributions.
Dr. Christa Kühn, Director of Germany’s Leibniz-Institut für Nutztierbiologie (FBN), introduced the BovReg project, which is a part of the global FAANG initiative. BovReg aims to provide a comprehensive map of functionally active genomic features in cattle and help to understand associations between the epigenome and complex phenotypes related to robustness, health and biological efficiency. Gentec is excited and proud to participate and provide tissue samples from Kinsella crossbred animals characterized by feed efficiency ratios and methane production. “Team members and partners will have access to an internal database,” said Dr. Kühn. “BovReg will develop biology-driven genomic prediction tools by integrating biological knowledge of regulatory genomic variation and genomic selection methods for local and global cattle populations.” The results will advance our efforts in more environmentally sustainable cattle production and food security while respecting animal welfare.
Dr. Colin Kern, a postdoctoral fellow in Dr. Huaijun Zhou’s group at University of California Davis, presented their updates for the FAANG project. “We completed the first comprehensive identification of regulatory elements in farm animals across eight tissues in the chicken (White Leghorn), cattle (Holstein), and pig (Large White) genomes,” he said. The data and results from the FAANG pilot projects are available on the FAANG data portal and viewable on genome browsers via a UCSC track hub. These datasets will provide a resource for our Gentec swine studies to better annotate current GWAS results and improve the understanding of complex traits, including disease resilience and meat quality.

Swine Workshop
The swine workshop aimed to highlight updates on how the transcriptome, genome assembly and GWAS can be used to identify markers linked to important production traits in swine. It covered hot topics in complex production traits including meat quality, pig behaviour and aggression, feeding behaviour and feed efficiency, sperm quality, pig health and disease resilience.

Dr. Claire Rogel-Gaillard, a senior scientist at the French National Institute for Agricultural Research (INRA), presented her group’s work on updating the annotation of the swine leukocyte antigen (SLA) complex on chromosome 7 from the genome assembly Sscrofa 11.1. This work makes significant contributions to the study of disease responses because the SLA complex plays essential roles in the immune system, including peptide presentation and self/non-self-recognition. Dr. Rogel-Gaillard’s group reannotated the whole SLA genomic region, refined the annotation of 27 SLA genes, corrected the gene structures and names, and characterized the gene allele sequences and splicing variants. I was so excited to talk with Dr. Rogel-Gaillard afterwards during my poster session. As one of our collaborators on the pig project of disease resilience, Dr. Rogel-Gaillard was very interested in our studies and the results of exploring complete blood count as a phenotype for disease-resilience in pigs. She also offered to help me further annotate my GWAS results regarding the SLA complex. This help will make our GWAS results more meaningful and help us to better understand and explore the immune functions and responses related to disease resilience.
We also talked to and had lunch with Dr. Jack Dekkers and his group, who are also collaborators on the disease resilience pig project. His postdoctoral fellow Dr. Kyu-Sang Lim and PhD student Yulu Chen presented their results and indicated the potential of using the blood transcriptome and protein levels of young healthy pigs as biomarkers to improve pig disease resilience, respectively. Dr. Lim and I were excited that we found common results between his blood transcriptome analyses and my GWAS of complete blood count. This connection will strengthen our collaboration and enhance confidence to cross-validate and further develop our findings to improve pig disease resilience. The pig resilience project is led by Mike Dyck at UAlberta and is a partnership with PigGen Canada with funding from Genome Canada and other agencies, including USDA NIFA.
Dr. Joan Lunney is an international authority on pig immunology and genomics, a research scientist at the Beltsville Agricultural Research Center, and a collaborator on the PRRS Pregnant Gilt Model (PGM) that aims to assess maternal and fetal factors that could be predictive of PRRS severity and resilience in fetal pigs. “This study affirmed the diversity of fetal pig anti-PRRSV response within each litter. It has set the stage for more detailed analyses now underway to probe for key markers of fetal pig PRRS resilience,” said Dr. Lunney in the swine workshop. Talking with Dr. Lunney afterwards, I felt very lucky to participate in the sampling work for PGM during my time at University of Saskatchewan. And I will never forget how well and efficiently it was organized by our collaborator, Dr. John Harding, a professor there.
Genome editing and livestock farm animals’ health and welfare
Genome editing using CRISPR-Cas9 to improve farm animals’ health and welfare continues to be a hot topic. The simple disruption of the CD163 gene is a recent breakthrough in gene editing in pigs, and confers complete resistance to PRRSV infection. It is the only method that can fully protect pigs from infection with PRRSV and thus also from transmitting it. Gentec collaborator Dr. Andrea Doeschl-Wilson and her group at the Roslin Institute, University of Edinburgh, developed a genetic-epidemiological model to predict how gene editing may affect PRRS outbreaks and whether the dispersion of gene-edited pigs in a commercial pig herd could help to eradicate this devastating disease at a national level. Considering many different scenarios, Dr. Doeschl-Wilson suggests that PRRS eradication through gene editing alone is not feasible and would require large proportions of gene-edited pigs. Complementary methods, such as vaccination and introduction of genetically resilient pigs, are being explored in current Gentec projects with collaborators around the world. These findings would be significant to achieve the hitherto unprecedented opportunity to eradicate PRRS and improve pig health in the face of challenged commercial environments in the future.
It is always exciting to make new friends and meet Gentec people and old friends during the conference. PAG is such an informative meeting that offers a fantastic opportunity to catch up on the latest advances and technologies. I highly recommend this meeting as a great place to learn. Beyond this, PAG provides practical and informative workshops to train students and postdocs for academic and industry jobs with the latest tools and technologies, which can be applied to our studies and research work immediately. As representatives of UAlberta and Gentec, we will share our learning and experience with our friends, colleagues and collaborators.
