Capturing relative phenotypes to help us understand boar fertility

Amanda Minton, Associate Director of Reproductive Technology at Acuity Swine and Karl Kerns, Assistant Professor at Iowa State University, discuss capturing relative phenotypes to help us understand and ultimately improve boar fertility.

R&D: Understanding index distribution and accountability in competitive comparison

Justin Fix, Director of Business Development and Genetic Improvement with Acuity and Caleb Shull, Director of Research at The Maschhoffs discuss how genetic evaluation varies from nucleus to commercial production and how that variation creates a bias in data analysis.

New Northwest Iowa Extension Swine Specialist is Ready to Help

There's no question too big or too small for Ashley Englin, new swine specialist for Iowa State University Extension and Outreach in northwest Iowa. On the job just since Jan. 29, she's already working to develop contacts, meet colleagues and clients, and prepare to offer great service to producers and others in that area. "My primary responsibility is to provide resources to people to improve the local and state swine industry," she said. "I want everyone to know I'm a resource to call on when needed." Englin said her background provides with her a great deal of first-hand experience and an understanding of what takes place within the day-to-day operations of a farm, and that's a big plus in this position. "I was introduced to agriculture at an early age while growing up in Le Mars and participating in 4-H," she said. "I decided to pursue my passion by attending Iowa State University where I received a bachelor's degree in animal science." After graduation, she began work as a nurRead More

PRRS virus-resistant nucleus herd ready for breeding upon regulatory approval

CRISPR is king. That’s what Cooperative Extension Professor in Animal Genomics and Biotechnology at UC Davis, Alison Van Eenennaam, and her post-doc, Alba Ledesma, found out when the European Food Safety Authority asked them to do a review of the global research in genome editing of livestock for food and agricultural production. “About 80% of all of the edits detailed in peer-reviewed research publications were being done using the CRISPR/Cas9 system. Other editing technologies such as zinc-finger nucleases and TALENs, predated CRISPR/Cas9, and comparatively they're more complicated and expensive to use. They do the same thing, make a double-stranded break in the DNA at a targeted location in the genome, but they're more expensive and complicated to use,” Van Eenennaam says. “That's part of the attractiveness and the democratization of genome editing is that with CRISR/Cas9, you just need to order a different CRISPR guide and you can target the Cas9 to cut at a different region in thRead More

Q&A: Pork, pathogens and progress—a close look at PRRSV research

The pork industry provides people across different cultures a considerable source of protein, essential nutrients and a versatile ingredient for diverse culinary traditions. So, when the problem of porcine reproductive and respiratory syndrome virus (PRRSV) infection in the pork industry results in an economic loss of $650 million annually in the United States, finding a solution is of critical significance.Read More
