Breeding Myths #1

Breed the best to the best and hope for the best I would absolutely subscribe to this theory if we were breeding purebreds, but we are not, we are breeding hybrids! If we were breeding purebreds, full siblings would look exactly the same, like a line of peas in a pod, but they don't. Foals […]

Explanation of Mating Reports

Mating Reports Overview One of my greatest frustrations as a Stallion Owner is Truenicks. It is the go-to mating software because it is free for breeders to use and it is easy to access as it is owned by Bloodhorse Magazine.

Truenicks vs. Pedigrees 360

Which One is Better? Every Monday morning I receive an email from TrueNicks showing me which reports have been run on Airoforce or Uncle Vinny.  Every time I look at them I get frustrated that the breeders have not contacted me directly and asked me to run a pedigrees360 report or a G1 Goldmine (or […]
