[QUOTE="rocfarm, post: 1765955, member: 42715"] Read that yesterday. If you have genetics you want to keep, then heifers out of heifers seem to be a must. But I’m not too interested in purebred genetics at this point. I agree with the comment above that the best replacements come from older cows that are proven. Maternal traits are not that heritable, so if speaking purely in terms of a good, productive cow, then it seems to always be see what you get out of that 1st calf heifer in regards to how she does on that first birth and then make a culling decision. Older cows tend to give the best care as well (they give more milk as they mature (up to about 8 or 9 years) and know how to care for the calf a bit better, so you are probably going to have some benefits for that replacement based on no rough patches early in life for the calf (easy birthing, likely larger weaning weight, etc.). And she likely has a good teacher in her older momma. These advantages probably make a better replacement cow as well. I look forward to the day I have some older cows to make me some replacements. I’ll try to find some statistics on this sometime. Would be interesting to see if it makes a financial difference. [/QUOTE]
