The genomic regions make sense. Genes involved with innate immunity, such as the interleukins, were in the identified regions. The research team did a challenge experiment where they infected cattle with 7 different pathogens. They collected tissues from the challenge animals and have done an...

A Steak in Genomics: Jim Womack gave an update about the USDA CAP project on Bovine Respiratory Disease. http://steakgenomics.blogspot.com/2014/05/jim-womack-update-on-bovine-respiratory.html

A Steak in Genomics: Charolais Association will host a tour prior to BIF to discuss development of genomic-enhanced EPDs. https://www.facebook.com/SteakGenomics/posts/1436960666558847

Register now for the 2014 Beef Improvement Federation Annual Convention! See blog post for more details. http://steakgenomics.blogspot.com/2014/05/2014-beef-improvement-federation-annual.html Have any of you attended BIF before? What did you think? What improvements in the meeting would you...

Thanks for the feedback knabe. In terms of high resolution parentage testing, I think you are right, but I am going to write a blog post about why that is a good thing and the benefits of that. (Thanks for teeing up another post!) As I've mentioned before, I think you could use genomic...

Lots of good suggestions. I am also a fan of 719T, lots of depth, lots of muscle.

I like him. Like the way he holds his head and his rib shape. Wish he had a little more muscle shape. How thick is he from the rear? Should make a nice steer project.

Few updates and questions about my blog. First off, I have created a Facebook page for my blog and extension program. If Facebook is your thing and you enjoy beef genetics and genomics, please like my Facebook page and share it with your friends. https://www.facebook.com/SteakGenomics Second...

New blog post at Steak in Genomics about new Simmental TraitTrac system. http://steakgenomics.blogspot.com/2014/05/american-simmental-associations-updates.html

I like the comments about knowing your cow's calving ease (maternal calving ease) and balancing the bull's calving ease (direct calving ease). Here are the percentile rank recommendations for direct calving ease that we make for the Missouri Show-Me-Select Heifer Replacement program Active Sire...

New blog post at Steak in Genomics guest authored by Mike Kasten. Mike discusses the performance of 3 pens of cattle in the Quality Beef by the Numbers program and recent cattle prices. Data collection is the first step in genetic improvement...

Just posted on another post, before I read this thread. Glad to see people are realizing they would loose 25% of calf crop from breeding carrier to carrier. Lots of great answers here!

Breeding a carrier cow to a carrier bull is inhumane in my opinion. If you care about animal welfare, you would not take the chance of producing an affected calf. I support using carrier animals [shameless self-promotion here...

New blog post about "Green Pastures, Genetics, and Environment." http://steakgenomics.blogspot.com/2014/04/green-pastures-genetics-and-environment.html Thanks for your comments on the last post! This post is in response to one of those comments. As always, your feedback is welcomed.

Speaking of FTO. http://www.nature.com/news/new-contender-for-fat-gene-found-1.14863

We haven't had the sequence data to look at this yet. The region of interest is the entire genome. We don't pick out gene regions in a genomic prediction. We fit the entire genome.

Don't know.

Are you talking metabolic pathways? The larger the effect the more accurate the estimated effect size is. The smaller the effect, the less accurately its effect is estimated. But, when we do the analysis, even though the effects are small they cluster in the same gene networks. In my mind this...

Because so much variation was lost when cattle were domesticated, I don't think you can reconstruct aurochs from domestic cattle. You can make something that looks similar, but the DNA is not necessarily the same.
