Abstract

Artificial Insemination in Fixed Time (IATF) is a technique that makes possible the use of artificial insemination in cows, reducing the problems of observation of estrus, thus enabling the reduction of the need of breeders in natural mating. The objective of this work is to economically evaluate...
