Abstract(s)
Os principais objetivos deste estudo foram: avaliar a relação entre o perímetro escrotal, a temperatura do ar e o gradiente de temperatura da superfície escrotal com as características seminais de carneiros da raça Churra Galega Bragançana durante o outono. Para o efeito foram utilizados 6 carneiros adultos desta raça. A temperatura do ar foi medida com recurso a um termómetro. O gradiente de temperatura da superfície escrotal foi medido com o auxílio de uma câmara térmica e o perímetro escrotal com uma fita métrica metálica. Os ejaculados recolhidos foram avaliados quanto ao volume de ejaculado, à concentração espermática, à concentração do ejaculado, à motilidade espermática e à percentagem de espermatozóides normais. Tendo em conta o gradiente da temperatura da superfície escrotal, os carneiros foram divididos em três grupos: grupo 1 (≤ 5,4°C) , grupo 2 (5,5-6,4°C) e grupo 3 (≥ 6,5°C). No que concerne ao perímetro escrotal, os carneiros foram divididos em 2 grupos: grupo 1 (< 30 cm) e grupo 2 (≥ 30 cm).
This study's main objectives were: evaluating the relationship between scrotal perimeter, air temperature and the scrotal surface temperature gradiant with the respective lamb seminal characteristics of the race Churra galega Bragançana during autumn. To that effect were utilized 6 adult ram of the mentioned race. The room temperature was measured using a termometer. The scrotal surface temperature gradient was measured with the aid of a thermal chamber and the scrotal perimeter with a metal metric tape. The ejaculate samples were evaluated for sperm volume, sperm concentration, ejaculate concentration, sperm motility and lastly the percentage of normal sperm cells. Considering the scrotal surface temperature gradient, lambs were divided in three groups: group 1 (≤ 5,4°C) , group 2 (5,5-6,4°C) e group 3 (≥ 6,5°C). Regarding the scrotal perimeter lambs were divided in 2 groups: group 1 (< 30 cm) e group 2 (≥ 30 cm).
