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, ...

This study compared a number of semen parameters of two separate groups of the common marmoset monkey (Callithrix jacchus) in order to determine the effect of a continuous potentially stressful situation on these parameters, and thus on the monkey's reproductive ability. The semen from 16 adult male marmoset monkeys was collected and analysed to compare semen parameters between a 'normal' (cont...

Abstract Increasing evidence supports the existence of a microbial community in bovine semen, and that this seminal microbiota may influence not only male reproductive health, but also female offspring health through transfer. In study, we evaluated beef bulls (BW= 503±7.2 kg) fed common diet to achieve moderate (1.13 kg/d) or high (1.80 rates weight gain. Semen samples were collected at day 0 ...

Spermatozoa represent a tissue readily accessible for study after various exogenous perturbations. To characterize the lipid composition of monkey sperm and to establish a baseline from which dietary or pharmaceutical influences may then be evaluated, we collected semen samples from five rhesus monkeys by electroejaculation and analyzed the sperm for sterols, fatty acid composition, and the mol...

The aim of this study was to assess whether refractoriness to long photoperiod (LP) could be reversed by subjecting tomcats to a period of short days. Our hypothesis was that photoperiod changes can avoid refractoriness and restore sperm quality and production to that before refractoriness. Tomcats (n = 6) were housed in a conditioned room with LP (12L: 12D) for 45 days of acclimation and then ...
