The objectives of the present study were to determine the effects of six different antibiotics in controlling the growth of semen contaminating bacteria and if these antibiotics have any adverse effect on Awassi ram spermatozoa. Semen samples from six mature Awassi rams were used in this study. A total number of 120 ejaculates were collected from the rams using an artificial vagina once a week....

Introduction Primary breeders are currently faced with the same problem plaguing most animal industries, rising production costs. Labor, feed and energy costs are forcing primary breeders to consider more economical ways of maintaining gene pools. One way to reduce such costs is with the use of frozen semen. With frozen semen available from superior sires, primary breeders will have the tool to...

It was the aim of the present study to test whey as protective protein for the sperm cell in the long-term boar semen preservation medium TRIXcell. Analyses of sperm cell motility using computer-assisted semen analysis (CASA) indicated that the whey protein Porex has a similar protective effect as bovine serum albumin (BSA) in maintaining viability of stored boar sperm. Boar sperm diluted in TR...

This study was designed to analyze boar sperm to compare motility, acrosome morphology, viability and ATP by various preservation methods between Duroc boar A with cold shock resistance sperm and Duroc boar B with cold shock sensitivity sperm. Semen volume, sperm concentration, motility and normal acrosome between Duroc boar A and B did not show any differences within 2 h after collection. Ther...

The present study was aimed to test the efficacy of adding vitamins C or E to Tris-fructose-egg yolk diluent to increase Awassi ram sperm storage period at 5 ˚C. Semen samples from six mature Awassi rams were used in this study. The semen samples were diluted by Tris-glucose-egg yolk. Diluted semen sample was divided into three parts. The first part was added with 0.9 mg mL-1 vitamin...

Semen extenders based on egg yolk and milk have been widely used in seminal preservation. However, they present health risks due to the transmission of pathogens. Therefore, new studies emerged seeking for a diluent vegetable origin, capable guaranteeing sperm quality eliminating risk contamination. In light above, meta-analytical review was conducted determine effect coconut water as extender ...
