Abstract
In the state of São Paulo, as in the rest of the country, the performance indexes of dairy herds from smallholders are extremely deficient, despite the high cost of land and the proximity to public research and extension institutions. Therefore, it is urgent to find viable strategies that allow changing this situation, to prevent the producer from moving away from the activity. In this se…

Abstract
In the bovine species, information on how biological ageing affects reproductive physiology and the quality of gametes is sparse and limited. The main obstacle to carrying out studies on the influence of age on the reproduction of cattle derives from the difficulty of finding adequate experimental material, since commercial farms discard their animals long before they cease their reproduc…

Abstract
Estrogen-based protocols for synchronization of ovulation are widely used in Brazil, due to reduced cost and good efficiency in pregnancy rates after fixed time artificial insemination (TAI). However, restrictions on trade in animal products treated with estrogen may limit its use in the future. An alternative to estrogen-base protocols is to replace estrogens by GnRH, in some variations …
