The technology drive from egg production in relationship with genetic selection makes today’s egg production quails quite different from those of a decade ago. For instance age at 5 percent production is now earlier and total egg number has increased. The quail eggs are renowned for their high biological value (George, 2002). Although it was first considered mainly as a model animal for commerc...

the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

tomato seedlings were inoculated with t. harzianum bi (106 spores/ml) and salicylic acid (5mm) other separately or combined together in the greenhouse environment. the effect of salicylic acid was investigated on growth of antagonistic agent in vitro. for an investigation of the effect of salicylic acid and of antagonist on pathogenecity factor, treatment with t. harzianum bi by drenching soil ...

The present study was carried out to determine the sex of the fertilized white layer eggs with using morphological measurements. A total of 300 Super Nick White Layer (54 wks of age) eggs were incubated and sexed in the end of incubation period. Before incubation egg length, width and weight were measured. The egg volume and shape index were estimated with using these measurements for each egg....

1. The reaction between ferricyanide and egg albumin in solutions of urea, guanidine hydrochloride, and Duponol has been investigated. 2. In neutral medium ferricyanide oxidizes all the SH groups of egg albumin that give a color reaction with nitroprusside. In neutral medium ferricyanide appears to react only with the SH groups of egg albumin. The quantity of ferrocyanide formed can accordingly...

Egg-laying behavior of free-living Willow Ptarmigan (Lagopus lagopus) was studied at Chilkat Pass, B.C. to learn if females were indeterminate egg-layers in natural conditions. Eggs were removed from clutches of experimental birds during laying, usually beginning with the third egg. All birds were determinate egg-layers and there was no difference in the number of eggs laid by control (K = 8.11...

The effect of streptozotocin-induced diabetes mellitus was studied in mice infected with Schistosoma mansoni. Faecal egg excretion was lower in diabetic mice but worm load and total amount of eggs in the intestine tissue were equal to the control group. Evaluation of an oogram showed a great number of immature dead eggs and a low number of mature eggs in diabetic mice. It was therefore conclude...

A total number of 330 native Libyan chicken eggs were collected from smallholders over different areas of south Libya to determine and classify some quantitative and qualitative traits in Libyan native fowls. The quantitative traits studied in the current trial were fertility and hatchability percent, egg weight, eggshell characteristics (weight, thickness, area), chicks weight and body measure...

A total number of  5520 female and  480 male breeders (Arbor Acres plus) at 42wks of age  were used in a 10-week-trial to investigate the effect of an enzyme complex on  the quality  and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...
