Abstract: Bilateral ovariectomy, castration or sterilization, is a surgical procedure that consists of removing the ovaries, using different techniques, being used by producers in the sectors of dairy cows and heifers in feedlots. The technique prevents pregnancy and eliminates the main source of estrogen at the ovarian level. The advantages for sterilized heifers include: prevention of pregnant heifers in the feedlot, elimination of feed additives that suppress estrus, does not require testing for brucellosis and tuberculosis, which facilitates their mobilization for transport outside the country, better average daily gain and feed conversion compared to non-castrated heifers, and castrated adult cows obtain better carcass yield and fat marbling in muscle mass, generating a better cost-benefit ratio at slaughter. The American Veterinary Medical Association recommends that proper aseptic technique and restraint be used in all procedures, and that flank oophorectomy performed without anesthesia is inhumane. Pain and discomfort should be minimized as much as possible before, during, and after the surgical procedure. Performing a pregnancy diagnosis before sterilizing heifers could reduce the risk of complications.
