The study was conducted at the Ruminants section of Teaching and Research Farm University Ibadan, Ibadan to evaluate effects slaughtering weights on meat yield other chevon characteristics West African Dwarf bucks (WAD). Fifteen WAD were fed similar diets before sacrificing nine three pre-determined 15, 20 25kg relative percentage proportions Eviscerated Weight-EW, Hot Carcass Weight-HCW, Dress...

This study was designed to determine the levels of parasitaemia on 20 healthy domesticated rabbit bucks infected with Trypanosoma brucei brucei over a period of eight weeks. Ten out of the 20 bucks were infected with 1 ml of the parasite containing 1 X 10 trypanosomes and known as infected group A, while the remaining ten bucks were left uninfected as group B. The infected bucks were monitored ...

Photoperiod modulates reproduction in goats. We tested the hypothesis that the excitatory glutamatergic tone is reduced in the photoinhibited goat. The objectives of this study were to determine the effect of photoperiod and glutamatergic stimulation on LH, GH, and testosterone (T) secretion in goat bucks. Eight mature, intact bucks were used in two simultaneous 4 x 4 Latin square designs. Vari...

Independent of whether natural mating or artificial insemination is used for breeding, libido (sex drive) is evidently crucial to reproductive competence in all male meat animal species. Breeding goat bucks vary in their levels of libido; therefore, there is a need for the development of a predictive standardized test for estimating sex drive. The objective of this study was to evaluate libido ...

In the present study, three experiments were designed to identify most appropriate technique for freezing rabbit semen. Experiment 1 aimed determine optimal levels of dimethyl sulfoxide (DMSO) contents in medium and their effects on individual bucks. Semen ejaculates each buck (n=15 bucks) mixed split into portions extension with a containing varying concentrations DMSO (0.75, 1.0, 1.4 M). Dilu...

Two parallel schemes of crosses were practised involving the Spanish maternal line called V-line (V) and Saudi Gabali (S) rabbits. The first scheme began by crossing Saudi Gabali bucks with V-line does to get the F1 cross (½S½V), then does of this F1 were backcrossed with bucks of V-line to get ¾V¼S, then the progenies of the backcross were inter se mated to get (¾V¼S)2, followed by two more ge...

South African indigenous bucks are raised under extensive conditions and are more likely to reject artificial vagina (AV) due to their limited contact with human beings, as they are less handled. The purpose of the study was to compare goat semen collection techniques used for goats based on semen traits of South African indigenous bucks during the natural breeding season. A total of eight Sout...

The present study was conducted to assess the availability of Black Bengal breeding bucks in five districts from the Northern part (Lalmonirhat and Rangpur), Central part (Tangail and Mymensingh) and Southern part (Khulna) of Bangladesh and also to explore the relationship between distance of does from these breeding bucks and type of scarcity. The data were collected using a pre-tested questio...

Quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. The contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...
