How many times does a bull mate with a cow?

General recommendations for bull:cow ratios: The textbook recommendation for bull:cow ratio is typically 1 bull:20-30 females, with mature bulls closer to the 1:30 ratio and yearling bulls at 1 bull:20 cows. In cows in which estrous synchronization is used, the recommendations are altered by necessity.

Is a bull a cow?

They are suspended in an inverted position (compared to the bull and ram) with the tail of the epididymis uppermost. Particularly striking are the large Cowper’s glands.

How are the vas deferens removed from a bull?

Bulls may also be sterilized by a vasectomy in which a section of the vas deferens is removed so that sperm cannot pass to the outside of the body. The two vas deferens eventually unite into a single tube, the urethra, which is the channel passing through the penis.

Where do seminiferous tubules exit the testicle?

There are hundreds of individual seminiferous tubules in the body of the testicle which unite with one another to form a few dozen tubules that exit from the testicle and pass into the epididymis. The epididymis is a compact, flat, elongated structure closely attached to one side of the testicle.
