Biometry from crioula goat male reproductive in northeastern semi-arid during season dry or rainy
AbstractThe aim of this study was to compare the biometry from goat male reproductive between dry and rainy season. 46 and 52 genitals were collected from goat male in dry and rainy season, respectively. Testes were identify in right and left, measured in length, thickness and diameter. Epididymidis were weight. The deferents duct and penis were measured as length. Seminals vesicle were identify in right or left, weight single and measured in length, wideness and thickness. The parameters of weigh, wideness, thickness and length from different structures were submitted at Student t Test (P<0,05). The results showed had significant difference between the parameter measured in dry and rainy season (P<0,05), with except from seminal vesicle. It was showed values in dry season, with except from deferents duct. We conclude that parameters biometric from crioula goat in Northeastern semi-arid Brazil are inferiors to the mentioned in the international literature. These results demonstrated that the process of adaptation of exotic races brought by the Portuguese settlers along these 500 years provoked a decrease of the load of the same ones, turning them more rustic, however with normal reproductive characteristics, even in times of shortage of foods.
