Fifteen yearling fallow bucks were randomly assigned by BW to one of three treatment groups: control (C; n = 5), melengestrol acetate (MGA; n = 5), and zeranol (Z; n = 5), to evaluate effects on testicular development, aggressive behavior, antler growth, sexual activity, ADG, and BW. Zeranol-treated bucks received zeranol ear implants (36 mg) at 90-d intervals, and MGA-treated bucks received MG...

The objectives of this study were to characterize the mating capacity of bucks under range condition and assess the effect of mating frequency on flock fertility. Two adjacent flocks of crossbred goats (Criolloxdairy breeds; n=70 does, 5 bucks and 141 does, 4 bucks) were used in this study. The mating period was 16 and 20 days for each flock, respectively, in January and February, 1996. Mating ...

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...

BACKGROUND Aloe vera (Aloe barbadensis miller) is an evergreen perennial plant widely used in modern herbal practice and is often available in proprietary herbal preparations. OBJECTIVE This study was designed to investigate the semen picture and spermatozoa morphology of West African Dwarf (WAD) bucks treated with Aloe vera extract. MATERIALS AND METHODS Twelve sexually matured WAD bucks, ...

The effect of dry season supplementation with crop-residue-based rations on bodyweight, scrotal circumference and serum testosterone concentrations in Red Sokoto weaner bucks at 5, 6 and 7 months of age was investigated in the present study. There were 7 treatment groups which were fed a positive control ration (conventional concentrate) fed at 1 and 2% of the bucks’ bodyweights (Rations 1A and...

This study was aimed for selection of Black Bengal bucks based on their fertility and the performance of their progeny in field condition. Data on buck were collected from a nucleus breeding flock and on progeny at field level. The traits considered were birth weight, weight at every 3-m interval up to 12 m of age. Average daily gain (g/day) on 90 progeny produced from 10 bucks and semen parame...

INTRODUCTION One strategy for lowering the prevalence of obesity is to increase access to and affordability of fruits and vegetables through farmers' markets. However, little has been documented in the literature on the implementation of such efforts. To address this gap, the Division of Nutrition, Physical Activity, and Obesity (DNPAO) sponsored an evaluation of the New York City Health Bucks ...

The aim of the study was to compare the reproductive performance of Termond White (TW) and New Zealand White (NZ) bucks with various behavioral types. The empathic and novel-object tests were implemented to determine the patterns in rabbit reactions: -Aggressive, -Tame and -Timid. The comparison of bucks’ behavior with mating duration and fertility rate did not evidence significant relations. F...
