[QUOTE="Jeanne - Simme Valley, post: 1742783, member: 968"] "Supposedly"---- breeding early in the cycle produces more heifers, but lower conception. Breeding later, bulls, but higher conception. Flush researcher told me this is based on the fact that heifer sperm is fatter and slower than the sleek fast male sperm. Males get there first but the egg has not been released. The females get there and are still viable when the egg becomes available for fertilization. Also, I've heard that the PH in the uterus can be favorable for heifer or bull sperm. I've heard of people putting vinegar in the water, but don't know if that was to improve males or females. [/QUOTE]
