Water-soluble proteins, mainly livetins (a-, /?-, y-), are present in hen egg yolk (Martin, Vandegaer & Cook, 1957). They represent 5% of fresh yolk solids (Saito, Martin & Cook, 1965). During the later stages of incubation the watersoluble proteins (water-soluble fraction, WSF) undergo a marked increase in relative proportion; after 15 days of incubation they form over 15% and at 18 days over ...

This study tested different concentrations of egg yolk in canine freezing extender void of glycerol, a commonly used cryoprotectant, by examining the motility and morphology throughout the freezing process: initial (baseline after extender added), post-cool (after three hours at 5°C) and post-thaw (after freezing.) Initial values of pH, osmolarity, motility and morphology were obtained for comp...

The site of deposition of Salmonella enteritidis in eggs could influence the extent to which this pathogen multiplies before refrigeration achieves growth-inhibiting internal temperatures. The first part of this study sought to determine whether S. enteritidis inoculated onto the exterior (vitelline) membrane surface of egg yolks was able to penetrate into and multiply within the yolk contents....

Semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. This study was conducted on 4rams (2 Ghezel Merinos and 2 Merinos Moghani) to evaluate the effect of two diluents in Khalatposhan research station. Average age of rams was 3 years. Rams were trained to serve the artificial insemination and semen sam...
