[QUOTE="cow pollinater, post: 1220379, member: 14661"] It's a junk number until the reliability is up in the .70 range and even then there is variation from collection to collection. PLUS you're looking at a +1 meaning 1% better than average... You can beat that fifty different ways by simply managing your cows for fertility. I'm not saying it's a bad thing, I'm just saying that it's a sales tool. ;-) Don't pick bulls based on 1% better conception, you'd have to have thousands of insemenations to see that 1% difference reliably and any other fluctuations you see would be environmental/management on your end. Pick the BEST bull and take whatever fertility information you have into consideration when you pick him. [/QUOTE]
