The study of pathological conditions of the male reproductive system is paramount to understanding reproductive inefficiency in the Sahel goat. In this study, 1048 Sahel bucks presented for slaughter at the Maiduguri metropolitan abattoir were evaluated for the presence of various pathological abnormalities of the reproductive system. A total incidence of 15.08% was recorded for various patholo...

Lipids are the main structural/functional components of the sperm, and their composition may undergo a series of modifications in relation to either physiologic events and/or diet. The effect of lecithin supplementation on reproductive and reproductive performance were studied in rabbits bucks. Twenty eight adult V line rabbits (at age between 7-8 months) were divided into four equal groups. Th...

Characterization of Black Bengal bucks and does was performed in this study. A total of 50 goats of different aged were studied. The experiment was performed in Black Bengal bucks and does at 1 day and at 3, 6, 9 and 12 months of age for measuring different parameters such as body length, heart girth, wither height, hip height, fore and hind leg length, head length and width, head length and wi...

Heat stress (HS) often blamed for suboptimal reproductive efficiency and is a worldwide problem, which inflicts heavy economic losses reflected in limiting the breeding season of rabbits to be normally from September to May in northern hemisphere and subtropical regions. The present experiment was conducted to study the effect of summer heat stress and the alleviating effect of some antioxidant...

The objective of this work was to study the effects of organic selenium and folic acid supplementation on productive performance and reproductive performance of rabbit bucks exposed to hot condition during summer condition. Twenty-eight male V-line rabbits 7-8 months old with average initial body weight of 3.4090.05 kg were randomly divided into four groups of 7 bucks each. Group 1 served as c...

This paper dwells on the histological structure and karyometric parameters of adrenal medulla non-pregnant maral does throughout year. It was found that in autumn synthetic activity norepinephrine-producing cells is lowest relation to other seasons Having compared our results with literature data, we identified sex-related differences glandular medulla, which indicates different mechanisms meta...

this study was focused on the effect of wattle trait on body sizes and scrotal dimensions of traditionally reared wad bucks in the derived savannah environment. data were collected from 153 bucks ranging from 4 months to 2 years of age and this included, scrotal length, scrotal circumference, body weight, height at withers, body length and chest girth. parameters for wattle traits included, wat...

Interest in the preservation of endangered breeds such as the Blanca Andaluza goat, has increased and some steps should be therefore taken to ensure it. The study was designed to determine the seasonal reproductive pattern of Blanca Andaluza bucks, and whether this affects the quality of their semen and its freezability over the year. Seven bucks were used and their body weight, testicular weig...
