Resumo: | This study aimed to evaluate the interference of daily gynecological exam on reproductive and productive parameters in Murrah buffaloes. Twenty-four buffaloes, which have calved in the autumn season, were milked once a day and kept on pasture, were divided into two groups: Research (RG; n=13) and Control (CG; n=11). The animals in RG were daily taken to the corral and submitted to gynecological examination and blood collection immediately after milking, from the 7th day postpartum until the first estrus and breeding day. Animals in CG were released directly to pasture after milking without any manipulation. The RG had smaller calving-first estrus interval (40.4±9.0 days) than CG (59.2±24.4 days; P<0.05). There was no difference in calving-conception interval and pregnancy rate at the end of the reproductive season (61.2±21.3 days and 86.0% RG; 71.2±30.4 days and 91.0% CG, respectively; P>0.05), as well as in milk production. The number of mating per conception was higher in RG (2.1±0.9) than in CG (1.5±0.5; P<0.05). We concluded that the daily management of animals used for research in this experiment affects some reproductive parameters, such as the number of mating per conception, but it does not affect calving-conception interval nor the pregnancy rate at the end of the season, as well as milk production, considering the management system and the production indices of the experiment.KEYWORDS: buffalo; gynecological exam; milk; research; reproduction. |

Este trabalho teve o objetivo de avaliar, em búfalas Murrah, a interferência da manipulação diária dos animais para exame ginecológico em parâmetros reprodutivos e produtivos. Vinte e quatro búfalas, paridas no outono, ordenhadas uma vez ao dia, mantidas a pasto foram distribuídas nos grupos: Pesquisa (GP; n=13); e Controle (GC; n=11). As fêmeas do GP, após a ordenha, foram diariamente, desde o 7º dia pós-parto até o primeiro estro e cobertura, conduzidas até o curral e submetidas a exame ginecológico e coleta de sangue. Os animais do GC, após a ordenha, foram liberados diretamente para o pasto sem nenhuma manipulação. O GP apresentou intervalo parto-primeiro estro menor (40,4±9,0 dias) que o GC (59,2±24,4 dias; P<0,05). Não foi observada diferença no intervalo parto-concepção e na taxa de prenhez ao final da estação reprodutiva (61,2±21,3 dias e 86,0% GP; 71,2±30,4 dias e 91,0% GC, respectivamente; P>0,05), bem como na produção de leite. O número de coberturas por concepção foi maior no GP (2,1±0,9) do que no GC (1,5±0,5; P<0,05). Conclui-se que a manipulação diária dos animais para pesquisa empregada neste experimento afeta alguns parâmetros reprodutivos, comprometendo o número de coberturas por concepção, mas não interfere no intervalo parto-concepção, na taxa de prenhez ao final da estação e na produção leiteira, considerando-se o sistema de manejo e os índices de produção do experimento.PALAVRAS-CHAVE: búfalo; exame ginecológico; leite; pesquisa; reprodução.
