One of the most common causes of salmonellosis of man and poultry is Salmonella Enteritidis which is often found in the digestive system of adult birds. The infected birds do not display any evident clinical symptoms and, at the same time, they excrete the bacteria into the surrounding environment. Studies are carried out by standard microbiological procedures which include the isolation of Sal...

A 54-year-old woman suffered an episode of dyspnea and edema affecting her eyelids, tongue, and lips a few minutes after intake of Lizipaina (bacitracin, papain, and lysozyme). She was treated with intravenous drugs and her symptoms improved within 2 hours. She had experienced 3 to 4 bouts of similar symptoms related to the ingestion of cured cheeses or raw egg. Specific serum immunoglobulin (I...

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...

Egg yolk constitutes the main storage compartment of the avian egg and the first nutritional source that supports embryonic growth. Most egg yolk components are synthesized by the liver of laying hens at sexual maturity and are secreted into the blood to be further transferred into the ovarian oocyte (yolky follicle) by receptor-mediated endocytosis. Egg yolk proteins are secreted as precursors...

Enrichment diets high in ground flax may cause irritation to the gut, which may affect absorption of omega-3 polyunsaturated fatty acids (ω-3 PUFA) from flax as well as other dietary enrichment ingredients. This study assessed the egg enrichment with ω-3 PUFA and Lutein when provided alone in the diet, in combination, or when fed in alternate day patterns. A total of 144 individually caged Lohm...

Carotenoids are partially responsible for the colors of plants and when consumed by humans and animals are deposited into tissues (e.g., skin and egg yolk in laying hens) and may have health benefits. Because carotenoids are more available when consumed from egg yolk sources than vegetables, this research examined the ability of the laying hen to deposit dietary lycopene, a carotenoid that impa...

The objective of this study was to determine the effects of various levels of dietary black cumin seed on egg production, egg weight, feed conversion ratio, egg shell quality, and egg yolk cholesterol. In this study, eighty 27-wk-old laying hens (Hyline-5 White) were randomly assigned into 4 groups with 4 replicates of 5 birds each (20 laying hens per group) and fed diets supplemented with 1, 2...

OBJECTIVE An experiment was conducted to determine the effect of superdosing phytase on productive performance and egg quality in laying hens. METHODS A total of 200 42-wk-old Hy-Line Brown laying hens were allotted into 1 of 5 dietary treatments with 5 replicates consisting of 8 hens per replicate. The positive control (PC) and negative control diets (NC) were prepared based on the recommend...

We analyzed the prevalence of thermotolerant Campylobacter spp. compared that of to Salmonella spp. in raw yolk and on eggshells. A total of 2,710 eggs were investigated for each bacterium. Viable bacteria were found in 4.1% (Campylobacter spp.) and 1.1% (Salmonella spp.) of the eggshell samples, whereas the egg yolk samples were negative for both bacteria.

the aim of this study was to develop a diet suitable for obtaining quail eggs enriched with omega-3 fatty acids with minimum disadvantages on egg quality. this 12 weeks study was performed to investigate the effects of fish oil (fo) and savory (satureja khuzestanica) essential oil (eo) supplementation in diets of laying quails at different ages, on their performance, egg quality, fatty acid com...
