Hello everyone,
I got a Genetics question.
So currently my parents and I have a herd of cattle in Guatemala.
We have two sires which are brahman but mediocre-looking(looking to make a better-purebred herd longterm)they are replaced every two years, and they are servicing between 200-220 heifers.
My question is the heifers were originally Zebu, Nelore, Guzerat, and some Holstein. In the last 15 years, the heifer's original traits or characteristics have slowly disappeared. My question is IF I were to do AI with the "best-looking heifers or close to purebred characteristics" will I phase out the other breeds or genetic traits?
Also after going through several generations of AI will the bulls be considered purebred??
I hope I explained my question correctly and I hope the wonderful people of this board can help answer my questions.
Also for AI, I'm looking to buy semen from bovine elite or other vendors and probably buy JD Hudgins semen or V8 Ranch. Their sires look really promising.
And to all that provide their input Thanks in advance, I'll see if I can post some old pics shortly. and some new ones I took last month.
