Pasteurization at 60 C cannot be used to eliminate Salmonellae from liquid egg white, since this process coagulates the proteins and destroys the functional properties of egg white. Therefore, other means of destroying these organisms have been investigated. These include storage of the dried egg white at 50 to 70 C (Banwart and Ayres, 1956) and irradiation with high voltage cathode rays (Nicke...

A total 2400 hatching eggs were obtained from Japanese quails breeders ranged from 100 to 150 days of age used to analyze the effect of shell color on fertility, hatchability, embryonic mortality and malposition as well as internal and external egg quality. Results revealed that shell color had significant effect on fertility and scientific hatchability while it doesn't affect commercial hatcha...

An experiment was carried out to compare the effects of laying hen’s diet supplemented with inorganic and different organic sources of selenium (Se) on quality and oxidative stability of eggs during storage. A total of 81, (35-week old) laying hens of Lohmann LSL-White were assigned to cages in a completely randomized design with 9 groups of treatment and 3 replicates of 3 birds. Hens in each g...

In many species, females store sperm between copulation and egg fertilization, but the consequences of sperm storage and patterns of sperm use for female life history and reproductive success have not been investigated in great detail. In hymenopteran insect societies (ants, bees, wasps), reproduction is usually monopolized by one or relatively few queens, who mate only during a brief period ea...

Goats are small ruminants that reared by the rural community for financial income and nutrition. This study was aimed to determine effect of vitamin C addition in tris–egg yolk extender on lifespan Sapera goat spermatozoa stored 5o C. Semen collected from 1.5 years old male goat. The ejaculates were diluted Tris-egg (T-EY) added with 0, 0.2, 0.3, 0.4 g C/mL T0, T1, T2, T3 groups, respectively. ...

Three Ottawa control strains and a current commercial laying stock were reared and housed in the same environment. Eggs were collected at 5 different hen ages throughout the 2 production cycles of the flock. The eggs were inoculated with Salmonella Enteritidis (SE), Pseudomonas fluorescens (PF), a combination of the 2, or sterile buffered peptone water and stored up to 5 wk. After storage at ro...

The present study was designed to see whether adding glutathione to tris-citric egg yolk extender improves the quality of buffalo bull spermatozoa stored at 5°C for five days. Semen collected from Nili-Ravi buffalo (Bubalus bubalis) bulls (n = 5) was diluted (37C; 10 x 10 motile spermatozoa per ml) with extender having glutathione (0.0, 0.5, 1.0, 2.0 and 3.0mM). The extended semen was cooled fr...
