I've been working on some new data models for the yearling sales season. The goal being that if the average sale has 3% Elite racehorses to all horses, and the average bloodstock agent gets about 10% Elite racehorses to purchases, if you can get a data algorithm to get you started with a shortlist at each sale with a little north of that latter figure, that you are putting yourself in a position for more consistent success. In analyzing the dataset, which is substantial, it i

In my previous post I discussed how advantage at a yearling or two year old sale can be found by looking specifically at offspring out of mares that have a CPI of 2.62 or better. Foals out of these mares represent an advantage over mares that have lesser race performance, all other things being equal. I also discussed how through the concept of missing heritability by specifically selecting for mares that could run themselves, we are hoping to diminish this effect that can in

In our last post we looked at a recent scientific study that detailed out the importance of the maternal line, in particular the race performance of the dam of a yearling in terms of its influence on the outcome of the resultant foal. Unsurprisingly, the study found that a good stallion could generally not negate the heredity effect of a poor race mare but that a good race mare could negate the hereditary effect of a poor sire. This finding is pretty much the same finding tha
