Adição de gonadrofinas em protocolos de IATF e fertilidade de vacas Bos indicus

Abstract

Currently, Timed Artificial Insemination (TAI) can be routinely applied in reproductive programs. TAI protocols are projected to promote the control of luteal and follicular functions, which results in satisfactory conception rates. A variety of protocols was projected according to characteristics and needs of different genetic groups, animal category and management. Recently, GnRH/PGF2α or estradiol/progesterone based protocols are used. The TAI programs are important reproductive management tools to improve productive and reproductive performance of dairy and beef cattle. Therefore, the correct incorporation of these programs, inside cattle breeding, increases the reproductive efficiency of the animals and, concurrently, productivity and economic return for the pastoralist.
