Abstract

This study presents results of technology transfer of the reproductive management of meat sheep production in an association of producers from Dormentes, PE, Brazil. Ninety-two local crossbred Santa Inês and Bergamácia sheep were used in three experiments. Experiment I evaluated two levels of Total Digestible Nutrients (TDN), and Experiment II evaluated three levels of urea in the supplement before the mating season. Total Weight Gain (TWG), Daily Weight Gain (DWG), parturition rate and prolificacy were measured. Experiment III evaluated the post-partum anoestrus and lambing interval. In Experiment I, it was observed that there was an average of 3.5 kg for TWG, 63.8 g/day for DWG, 86.9% for parturition rate and 1.1 for prolificacy. In Experiment II, it was observed an average of 0.56 kg for TWG, 13.4 g/day for DWG, 77.7% for parturition rate and 1.1 for prolificacy. In Experiment III, the post-partum anoestrus was 57.8 days, and the lambing interval was 209.8 days. The supplements showed to be appropriate for weight gain and maintenance of reproductive activity of sheep during the dry season. The post-partum anoestrus and lambing interval of crossbred Santa Inês and Bergamácia sheep were short at the beginning of rainy season, which shows a high reproductive efficiency. Farmers actively participated in the activities and started to apply these techniques.

Index terms: family farming, fertility, mating season, meat cattle production, Ovis aries, participative research.
