Avaliação econômica da estação de monta em caprinos utilizando protocolo de sincronização do estro e ração flushing.

Resumo: O objetivo deste estudo foi realizar uma análise econômica do protocolo de sincronização do estro mais a ração flushing oferecida as cabras durante a estação de monta. Foram selecionadas 12 cabras da raça Saanen e um reprodutor, recebendo ração flushing. Utilizou-se esponjas análogas a progesterona, Prostaglandina e Gonadotrofina Coriônica Equina. O custo total foi de R$ 46, 17/animal. A utilização da sincronização torna-se uma medida viável economicamente quando comparada a monta natural. [Economic analisy on station of sum to Saanen goats using protocol of synchronization of estrous and flushing ration]. Abstract: The aim of the experimente was to realize na economic analysis of protocol synchronization of estrous and flushing ration offered to Saanen breed goats during station of sum. Twelve Saanen breed goats and onde billy-goat were used. Intravaginal sponges containing progesterone, Prostaglandin and Equine Corionic Gonadotroohin were used. The total costs were R$ 46,17/animal. The use of protocol of sychronization of estrous is more economically viable the sum natural.

Reproductive seasonality in Saanen goats managed in southeast Brazil.

The aim of this study was to characterize the reproductive seasonality during the period of one year in Saanen goats managed in southeastern Brazil These results endorse hormonal methods (estrus synchronization and induction of synchronized estrus) or natural (male effect, flushing or light treatment) more appropriate according to the time of year in the region. Saanen goats, managed under tropical climate in southeastern Brazil, have a breeding season set from March until mid-August with the transitional phase to the anestrus in September. It is extends to mid-December at the new one transition phase for the reproductive season in March.
