Spring breeding is in progress all around our route

Inside is a review of the estrus cycle, and how to time your inseminations to get an acceptable conception rate.     

Here is an extra tip:   If seeking bull calves, breed as late as possible in the cycle.   The male sperm cells are heavier than female, and as they will all wake up and be swimming about after you thaw the straw, the heavier male sperm cell expends more energy in the process.    Thus, they will have a shorter life in utero than the female sperm.

Breeding later  (like waiting until the cow refuses further mounting activity)  gives you higher percentages of live male sperm as they come in contact with the cow’s ovum (egg), thus increasing chances of a winning steer calf in next year’s crop.
