Reproduction Week: Estrous vs Estrus

Estrous (aka complete and repeating heat cycle) refers to the complete reproductive cycle that a female cow will experience and on average takes 21 days. This includes the formation of a mature follicle, release and creation of a corpus luteum, and associated shrinking of corpus luteum in non-pregnant cows. This cycle will repeat  

Estrus refers to heat associated behaviors such as mounting and willingness to be mounted. This is the period during the estrous cycle which a cow will be receptive to breeding. This is the perfect time for a cow to be bred, as breeding a cow with a bull or by using A.I (artificial insemination) during her receptive period will have a higher conception rate.

Today we shipped 4,581 gallons of milk.

There were no new calves born today.
