[QUOTE="cow pollinater, post: 1227757, member: 14661"] Not really. If you buy semen from a reputable source it has to have a certain number of viable semen in it to qualify as saleable semen and it is not a direct case of more is better as we'd all like to think. They have a formula that dictates how much semen it would take to improve conception above and beyond a certain point and it would take more than two straws to make any difference unless the individual bull isn't producing quality semen, in which case more is the only chance of making it better. Example: when sorted semen first came on the market a lot of guys would try to use two straws(at significant expense) to improve conception but their results were only marginally better than anyone else's. It would take around six straws of the originally packaged sorted semen to reliably improve conception rates beyond what was in one straw... The producers have a benchmark in mind and know that they have to have X amount in every straw to achieve that benchmark. The only real additional advantage to using two straws is if you do it twelve hours apart so that every cow has semen in the right place at the right time as they all ovulate at different times during the process but even then you're money ahead to just breed them once and then wait twenty one days and do it again. If you have to breed a beef cow three times then you're justified in treating her like she needs extra help to breed up but there's no reason to treat them like that before then. [/QUOTE]
