Cracking the bovine genome code

UC Davis receives funding for livestock genetics research

Researchers at the University of California, Davis are trying to to understand specific characteristics of the bovine genome.

Pablo Ross, an associate professor in UC Davis’ animal science department, will lead USDA-funded research (US$2.5 million over four years) to uncover what the sequence means.

“The bovine genome is made up of about three billion letters,” Ross told Farms.com today. “But we’ve never been able to understand much of what those letters mean. This research will help us translate that alphabet and find the most important parts of the bovine genome sequence.”

Scientists from the USDA and the National Institutes of Health sequenced the genome of a female Hereford cow in 2009.

The Bovine Genome Database, an online source based at the University of Missouri, released updates to the sequences in 2015 and again earlier this year.

 Discovering which parts of a cow’s genomic makeup are responsible for certain characteristics could bring important benefits to the cattle industry, Ross said.

“If we can find the regulatory elements (within the cow) that cause disease resistance, growth, meat production and fertility, we might be able to help develop better breeding programs,” he said.

The USDA is also supporting genomics research for the other two main types of livestock. Iowa State University received a grant for swine genetics, and the Western University of Health Sciences in Ponoma, Calif. received funding to study chicken genomics.

WARNING! Rough Start To Breeding Season!!

Video: WARNING! Rough Start To Breeding Season!!

WARNING! Sheep Breeding Season Begins With A Bang! Breeding season is officially underway at Ewetopia Farms, but it didn’t exactly start the way we planned!

This vlog begins with us sorting through our rams to find the perfect match for a customer’s breeding program. What should have been routine quickly turned dangerous when one of our more nervous rams panicked. In seconds, Arnie’s knee was injured, and then I was slammed hard onto the concrete floor — both of us taken down by one ram!

Thankfully, it was just bruises, but it’s a reminder of how unpredictable and powerful mature rams can be. Once we recovered, it was time to get back to the real work — the start of breeding season.

We sorted the ewes into four breeding groups (two Suffolk and two Dorset), checking parentage as they ran through the chute, deworming those that needed it, and setting aside thinner ewes for session two of breeding season in a month’s time.This staggered approach keeps lambing organized and prevents overcrowding in the barns.

From rogue rams to the excitement of new breeding groups, this episode is full of action. Stay tuned for the next vlog, where we’ll share how we chose the rams for each group!
