[QUOTE="KNERSIE, post: 593096, member: 4353"] Early, medium and late maturing animals refers to carcass maturity more than sexual maturity although there is a correlation between the two. ( The higher hormone levels after the onset of puberty inhibits the long bone growth and effectively starts the process of the closing of the growth plates on the long bones. Doc can put this in better words and descibe the technicalities much better than I can) Not at all, it would simply have wet his apetite. If you turned the young 14 month old bull out with 60 cows on marginal feed then he would rapidly lose condition and it would TEMPORARILY set his growth back, but they all will eventually get out of it again. Yes, very low as most fertility traits, but as I said in MM's thread if you need to hit a target where would you aim? Same answers. Most brahman influenced or brahman derived breeds are very capable to cycle and conceive to calf at two and most herds here are bred to calf at two. They can expect a higher % of open heifers and those can always be sold as replacements to those breeding to calve at 3 or held over for next year. Straightbred brahmans is pretty much the same deal, but you can expect fewer heifers to reach sexual maturity by breeding season than those who had another influence. Depending on your management and feeding conditions those heifers bred to calve at 2 will be smaller for a year or two compared to those who calved at 3, but again by the time they are 4 you won't be able to see the difference.
