Aspectos reprodutivos da raça Mangalarga Marchador no norte de Minas Gerais

Abstract

Equinoculture is an important activity of Brazilian agribusiness, moving billions a year and generating direct and indirect jobs. Considered the most numerous equine breed in the country, Mangalarg Marchador breeding is concentrated, especially, in the Minas Gerais state. Therefore, this study aimed to explore the clinical and reproductive scenario of the Mangalarga Marchador breed in the Northern Minas Gerais region to understand the breeding profile in this mesoregion. For this purpose, an online questionnaire was applied, which was completed upon prior acceptance of the Free and Informed Consent Form. The sample consisted of 52 breeders and the results obtained were subjected to frequency analysis by chi-square test. Among the data obtained, 38% of breeders reported leisure as the breeding purpose (p=0.53). Regarding the mating method, 40% reported the use of controlled cover. However, the majority (58%; p<0,01) performs artificial insemination, of which 62% use semen fresh (p<0.01). In addition, 51.92% reported the practice of embryo transfer (p=0,78). Regarding reproductive diseases, abortion, in females, and inguinal hernia, in males, were more prevalent with, 39.13% (p<0.01) and 83.33% (p<0.01), respectively. There was also remarkable technical assistance by veterinarians (86.53%; p<0.01) with monthly periodicity (16.55%; p<0.01). Therefore, it is possible to infer that the northern region of Minas Gerais requires improvements in sanitary-reproductive management applied to the Mangalarga Marchador breed to achieve the desired reproductive efficiency.
