Survival and reproduction are key features in the evolution of life-history strategies. In this study, we use capture-mark-resighting and multi-state models to examine survival senescence and reproductive senescence in six successive cohorts of fallow bucks that were studied for 16 years. We found that the overall age-specific survival probabilities of males were highly variable and the best-fi...

Six apparently healthy Borno white bucks weighing 15± 1.6 kg and aged 1.3± 0.3 years were used for this study. Two and half (2.5) ml Purit® (chlorhexidine gluconate 0.3% B.P W/V and cetrimide 3.0% B.P W/V CAPL Lagos) were injected bilaterally into the caudae of each epididymis following sedation with xylazine hydrochloride. The prestudy scrotal circumference was 20.1±1.5cm; Significant decrease...

The body weight and testicular and epididymal parameters of Afar, Long-eared Somali (LES), and Woyto-Guji (WG) breeds of goat were investigated. A total of 405 randomly selected bucks of Afar (n = 135), Long-eared Somali (n = 135), and Woyto-Guji (n = 135) were included in this study. The overall mean scrotal circumference (SC), testicular volume (TV), testicular length (TL), testicular weight ...

OBJECTIVE The present study examines the impact of Health Bucks, a farmers' market incentive programme, on awareness of and access to farmers' markets, and fruit and vegetable purchase and consumption in low-income New York City neighbourhoods. DESIGN The evaluation used two primary data collection methods: (i) an on-site point-of-purchase survey of farmers' market shoppers; and (ii) a random...

Caprine arthritis encephalitis is a worldwide, multisystemic disease caused by a small ruminant lentivirus. Although the main route of transmission is oral, detection of proviral DNA of the caprine arthritis encephalitis virus (CAEV) in caprine semen has been previously described. However, the presence of viral antigens in the male reproductive tract has apparently never been reported. The obje...

This study aimed at evaluating the effect of sex, age, breed and reproductive status on platelet count and total protein, and also to demonstrate the relationship between the two variables in goats during the cold-dry season. At the peak of the cold-dry season, 56 male and female goats belonging to Red Sokoto (n = 28) and Sahel (n = 28) as well as 14 Red Sokoto goats in the last trimester of ge...

Changes in semen quality occasioned by ejaculation frequency is one of the important yet neglected factor considered artificial insemination. Several factors have been shown to influence parameters, which sexual abstinence. Rabbits a very short interval between successive ejaculations hence, can easily be collected for examination. This experiment was carried out evaluate effect and graded diet...
