As I understand it, Santa Gertrudis are 3/8 Brahma and 5/8 Shorthorn, with maybe a little dairy cow thrown in there. The book was closed about 70 years or so ago, so you can't create new SG's from breeding Brahmas and Shorthorn, like you can Brangus. So my question is: what is the advantage of using SG over cattle that are not SG, but are 3/8 Brahma and 5/8 Shorthorn, if the Brahmas and Shorthorns are well bred cattle?
It is my guess that all you gain from using Santa Gertrudis is more uniformity, but you would surely lose some hybrid vigor, since the Santa Gertrudis are necessarily all fairly closely related compared to a fresh 3/8s--5/8s Brahma/Shorthorn cross.
I have the same question for Beefmaster cattle. I understand they are half Brahma, a quarter Hereford and a quarter Shorthorn, and again the stud book has been closed off for several decades. Wouldn't you do better to get the same mixture of breeds that are not line bred like the Beefmaster? In addition to more hybrid vigor, maybe they've made some improvements in those 3 breeds since the Beefmaster was concocted.
Or am I missing something?
