A couple of interesting papers

Three interesting papers have come across my desk that I thought were worth commenting on: The first is a genome wide study on height and other conformation characteristics in Franches-Montagnes horses. They used around 40,000 SNPs to do their analysis which is a lot less than what we used to do ours (~65,000) but the method is the same (comparing two groups and looking at where a signal is found). Interestingly they found two QTL's that explained ~18.2% of the heritable variation of height in horses. We don't think that this has a lot of application for Thoroughbreds (height doesn't relate a lot to performance) but they did find that the QTL region on ECA 3 associated with height at withers

Genomic Estimated Breeding Values

In our opinion there are two papers on what is wrong with thoroughbred breeding in terms of breed improvement that are really "must reads" for us. The first is a paper written by Burns, et al titled "The Status of Equine Genetic Evaluation" while the second is a great paper written by Dr Betrand Langlois titled "A consideration of the genetic aspects of some current practices in Thoroughbred Horse Breeding". I have provided links for both of these papers (the fact that one was written back in 1996 says a lot about the industry!) and I would suggest that you download and read them if you have a chance. Both papers outline how much the Thoroughbred Breeding industry is missing in terms of gene
