Abstract

The aim of the present study was to evaluate the effect of two doses of acetonide triamcinolone (TRI) at two distinct moments of gestation in the pre induction of parturition. Embryo recipients pregnant of the in vitro produced embryo were utilized as experimental model. A total of 175 pregnant embryo recipients were assigned into one of the four groups according to gestational period (280 or 285 days) and utilized dose of the TRI (1mg/60Kg or 1mg/100kg of body weight). The synchronization and assistance rates of the calving, the viability and body weight of calves at calving as well as retained placenta rate were evaluated. The TRI dose did not effect any variables responses (p>0.05). Least spread of the calving moment was observed in the recipients treated at the 280 days of gestation (p?0.05). The cow calving calf with ?42kg needed more assistance to calving (p?0.05) and these calves had lower viability than calves with <42Kg of the body weight (p?0.05). The data suggested that, independent of dose of the TRI, the pre induction with TRI at 280 days of gestation promote a good synchronization in the calving with a high predictable calving time without compromise the calf viability when compared with the pre induction at 285 days of gestation.
