Twenty-four, 79-wk-old White Leghorn hens were assigned randomly to three diets containing 0, 2.5, or 5.0% conjugated linoleic acid (CLA). The diets were fed for 4 wk to determine the effect of dietary CLA on quality characteristics of eggs. Eggs were collected daily and stored at 4 C for 1, 7, 21, or 49 d. At the designated times, the eggs were processed to evaluate water content, fatty acid c...

To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...

Eggs were collected from a single inline processing facility weekly for 3 wk (replicates). The eggs were stored at 4 degrees C and 80% RH. Sampling began the day after collection and continued each week for 10 wk. During analysis, 24 eggs were examined for egg weight, albumen height, Haugh units (HU), shell strength, and vitelline membrane strength for each replicate. Egg weight decreased (P < ...

The objective of the study was to examine the activity of different biologically active proteins in geese egg whites. The experiment was performed in 8 replicates on eggs collected from Italian White geese, Polish wild geese (Gegawa) and their cross line. Analyses of activities of cystatin, lysozyme and serine proteinases inhibitors in fresh geese egg whites were carried out. Moreover, trypsin ...

Current egg washing practices use wash water temperatures averaging 49 degrees C and have been found to increase internal egg temperature by 6.7 to 7.8 degrees C. These high temperatures create a more optimal environment for bacterial growth, including Salmonella Enteritidis if it is present. Salmonella Enteritidis is the most common human pathogen associated with shell eggs and egg products. I...

The objectives of this study were to investigate the effects of testis-epididymis cool storage on viability and progressive motility of buffalo epididymal sperm (EP) and to compare the influences of two basic semen extenders on post thaw EP viability and progressive motility. Abattoir collected buffalo testicles were allotted to three storage times (0 h: n = 10; 24 h: n = 10 and 48 h: n = 12). ...

this study was conducted to evaluate the effect of egg yolk and cooling on ram coated spermatozoa. semen was collected from three ram by artificial vagina contacted with a tube containing tris- fructose-egg yolk 15%. samples were pooled, centrifuged by 700 g for 10 min and removed supernatant. then, samples were diluted by tris-glucose and centrifuged again to remove seminal plasma and egg yolk...

1. New information is introduced and other information reviewed regarding the impact of egg storage on the integrity of the avian embryo. 2. Morphologically, the blastoderm from an egg which has been stored more than 10 days is often asymmetrical and may have an attenuated appearance. 3. Fresh egg breakouts coupled with the perivitelline layer sperm-hole determination procedure provide detailed...
