Larry is a producer and wants to save time when planning his artificial insemination program. He is able to control the ovulation in all his female recipients. This process is referred to as .

Estrus Synchronization

Explanation:

This is the procedure of manipulating the reproductive hormones of the female animals so that, the heat period occurs at  relatively the same time that is  convenient and  preferred by the producer. This is for  timed ovulation needed for techniques of artificial insemination for artificial selection. Thus the producer is able to plan his insemination programme to suite his work engagements.

The common hormones for this procedure are; Prostaglandins F2α :(which suppresses the oestrous cycle, to end, and restart the entire cycle and ovualtion again to suit the producer).  Progestins: (which inhibit heat and  ovulation until it is removed by the producer) and also induces oestrous cycle in a  non oestrous animals,and Gonadotropin Releasing Hormone.( for inducing oestrous cycle in  non oestrous animals, and for stimulating eggs production when needed.

Its advantages includes

uniformity in kids rearing,

uniformity in slaughtering period,

availability of milk round  the clock,

control of transmission of infectious diseases.
