Resumo: | The objective of this study was to assess the reproductive response of adult and prepubertal goats subjected to repeated laparoscopic ovum pick-up (LOPU). The study animals were divided into two groups, specifically, adult nanny goats (GA, n=10) and prepubertal nanny goats (GP, n=10), which were subjected to estrous synchronization and ovarian stimulation for LOPU. Both groups underwent six LOPU procedures at seven-day intervals and were subsequently subjected to controlled mating and pregnancy diagnosis to evaluate their future fertility. The study showed a reduction in the number of follicles visualized and in the amount and quality of the oocytes that were recovered and exposed to in vitro maturation. As indicated by the fertility test, however, no complications were found during the laparoscopic procedures that would impair the reproductive future of the animals. Therefore, a viable number of oocytes were obtained even with the decreased reproductive efficiency, proving that repeated LOPUs do not interfere with the reproductive of adult and prepubertal nanny goats. These results indicate a positive aspect of this procedure, allowing for increasing reproductive performance of this kind, when used for the production in vitro. |

Os animais do estudo foram divididos em dois grupos, especificamente cabras adultas (GA, n = 10) e pré-púberes (GP, n = 10), que foram submetidas a sincronização de estro e estimulação ovariana para LOPU. Ambos os grupos foram submetidos a seis procedimentos LOPU em intervalos de sete dias e foram posteriormente submetidos à monta controlada e posterior diagnóstico de gestação para avaliar sua fertilidade. O estudo mostrou uma diminuição do número de folículos visualizados, na quantidade e na qualidade dos oócitos que foram recuperados e expostos à maturação in vitro. Tal como indicado pelo teste de fertilidade, no entanto, não foram observadas grandes complicações durante os procedimentos laparoscópicos que pudessem prejudicar o futuro reprodutivo dos animais. Portanto, foi obtido um número de oócitos viáveis, mesmo com a diminuição da eficiência reprodutiva, provando que repetidas LOPU não interferem na reprodutividade de animais adultos e pré-púberes. Estes resultados indicam um aspecto positivo desse procedimento, possibilitando um aumento da eficiência reprodutiva dessa espécie quando utilizado para a produção in vitro.Universidade Estadual de São PauloUniversidade Federal de Minas Gerais (UFMG), Escola de VeterináriaUniversidade Estadual Paulista (Unesp)Cordeiro, M.
