[QUOTE="msscamp, post: 593726, member: 539"] I would say the cow that twinned would have the more fertile calves due to the fact that she cycled and bred back in 30 days. Why would twinning have any negative effect on fertility? True, twins could possibly have an effect on the cow breeding back, depending on management, but I would think that could be easily remedied with a little adjustment in feeding. No, I do not believe a calf from a subfertile cow will be more fertile than her mother. How could it be when fertility is an inherited trait? The bull might possibly influence that fertility a little bit, but I believe that mitochondrial DNA will prevent him from influencing it enough to make any kind of significant difference from this particular mating.
