The effects of L-carnitine supplementation (50-500 mg/kg diet) of a practical layer diet, based on maize, soyabean and wheat, on the performance of laying hens and some indices of egg quality were studied for 8 weeks, using 65-week-old hens kept in cages. Albumen quality (albumen height and Haugh (1937) unit score) was improved, while yolk index and yolk colour score were not affected by dietar...

Kanamycin, penicillin, and streptomycin were injected individually into air cells of newly set chicken and turkey hatching eggs, and assay was made throughout the incubation period to determine the location, potency, and duration of efficacy. By 24 hours, each antibiotic had diffused throughout the albumen. By six days, penicillin residues could not be detected, whereas kanamycin or streptomyci...

The goal of this experiment was to investigating of effects of different levels of nano chromium (N-Cr) in diet on egg quality and blood chromium content of japanese quail. Two hundred and forty laying japanese quail (45 day old) were randomly distributed to 20 experimental unit with 12 birds in cage pens of 40 × 80 cm. Experimental treatments include: 1) control national research council (NRC,...

The relationship between protein changes and egg quality during storage is a critical area of investigation in both basic science product preservation. Viscosity albumen are sensitive sign the deterioration process. Ovomucin, which present albumen, plays an important role gelation albumen. Egg freshness indices ovomucin concentration will alter response to time. This paper analyzed correlation ...

Salmonellosis and colibacillosis in poultry are two major zoonotic bacterial diseases often transmitted through eggs to the offspring. To detect prevalence of Salmonella and Escherichia coli bacteria in table purpose poultry eggs 85 eggs were sampled from Bareilly and Dehradun retail markets and an organized farm in Izatnagar. Salmonella could be isolated from four eggs and E. coli from 24 eggs...

We studied the effect of dietary source (organic or inorganic) and level of Se on the Se uptake of chick embryos. After receiving a low-Se diet for 16 wk, 126 Leghorn laying hens were randomly assigned to one of seven dietary treatments. Treatments consisted of feeding a low-Se basal diet alone or with one of three levels of added Se (0.1,0.2, or 0.3 mg/kg Se) supplied by sodium selenite or Se-...

The toxicity of the herbicide Erbitox E30, a commercial formulation of 2-methyl-4-chlorophenoxyacetic acid (MCPA) containing 28% MCPA as sodium-potassium salt and 72% of unknown ingredients, was tested on chick embryos. Sterile aqueous solutions of MCPA were injected into the air chamber at doses of 0, 1.5, 3.0, 6.0, 9.0, or 10.5 mg/egg on day 0 or on day 4 of incubation. The mortality rate for...

In this investigation the friction and wear performance of GUR 1020 medical grade ultra-high molecular weight polyethylene (UHMWPE) polymer under dry sliding, distilled water and egg albumen lubrication conditions were evaluated. The sliding experiments were carried out on a pin-on-disc tribometer. The contact configuration used was a polymer pin on a rotating AISI 304L stainless steel disc. We...
