Hereford and Red Angus Heifers Recruited for Genomics Research

The University of Missouri is recruiting 2,500 Hereford heifers and 2,500 Red Angus heifers to participate in a heifer puberty and fertility genomic research project. Heifers should be registered Hereford, registered Red Angus, or commercial Hereford or Red Angus. Hereford x Red Angus crossbred heifers targeted for the Premium Red Baldy Program would also be a good fit for the research project. Producers must be willing to work with a trained veterinarian to collect the following data: ReproductiveTract Scores collected at a pre-breeding exam 30 to 45 days prior to the start of the breeding season. PelvicMeasurements (height and width) collected at the same pre-breeding exam 30 to 45 days prior to the start of the breeding season. Pregnancy Determination Using Ultrasound reporting fetal age in days. Ultrasound will need to occur no later than 90 days after the start of the breeding season. In addition, heifers must have known birth dates and have weights recorded eithe

Technology Lag: We Don't Have Time

From Shauna Hermel's Twitter feed, I came across this article about David Buchanan's talk at the 2013 BIF Research Symposium and Convention. Buchanan said,
There is a sizable investment being made in agricultural research, which should result in new technologies, but it takes time for development and adoption, and then for the benefits to be realized. Historically, it takes about 30 years. We don’t have 30 years.
I also see technology adoption as a major shortcoming of the beef industry. This will be a continued theme of this blog and my extension program.

But, in this post I want to discuss the unresolved concern raised in Troy Smith's article. He quotes Buchanan as saying, "“We’ve done pretty well, but we could do better. But better selection tools just get us into trouble faster if we aren’t selecting for the right things.”

Yet, the article does not suggest what are the "right things". In your experience and based on scientific information, what are the right things?

I attended the farewell dinner for a retiring extension adviser here in Queensland a few years ago. When asked if the rate of adoption had improved over his career, he replied "Well yes, what used to take 20 years now only takes 19 years…."
In many ways the coming of genomics in beef has just made the genetic messages more complex and has added new jargon & new dimensions to the "black box". Genetic improvement as a permanent, sustainable means of herd improvement and supply chain improvement needs continuous education and simple profit messages but how to ramp up adoption is still a challenge

"It is dishonest to suggest, or imply, that BLUP (EPD) analysis will allow accurate genetic comparisons of all economically important traits across all environments. A trait such as fertility is determined by hormonal balance (largely unaffected by environment) and body condition (largely a reflection of environmental adaptation). It is therefore subjected to genotype X environment interaction. Animals performing well in one environment may perform poorly in a different environment. This is reflected in fertility. No mathematical model can correct for this in order to allow animals be compared across environments with regard to traits that are subjected to genotype X environment interaction."

Potentially more accurate selection (Genomics) for the wrong things will NOT improve genetics and/or profitability. For the RIGHT things…….
