experiment was conducted to evaluate the effect of different levels of egg yolk for coating and storing spermatozoa. ejaculates were collected from four rams. in each session, second ejaculates (n=4) were collected in a tube containing 1 ml coating buffers which were prepared by 10, 15 or 20% egg yolk plus tris-fructose. samples were pooled, centrifuged and the supernatant removed in the labora...

a total of 2000 records of egg quality of 746 birds and body weight data from 17th generation of fars native fowl breeding station were used to estimate the genetic parameters of egg quality and body weight traits. six univariate animal models with different random effects were fitted for each trait. a model with direct additive genetic and maternal permanent environmental effects was the most ...

Protein by-products from the extraction of lecithin from egg yolk can be converted into value-added products, such as bioactive hydrolysates and peptides that have potential health enhancing antioxidant, and antihypertensive properties. In this study, the antioxidant and angiotensin converting enzyme (ACE) inhibitory activities of peptides isolated and purified from egg yolk protein were invest...

Experiments were conducted to evaluate the potential for dietary garlic to influence egg yolk cholesterol concentrations and overall performance in different layer strains. Thirty-six, 28-wk-old, Hisex Brown,Isa Brown, Lohmann, Starcross, Babcock, and Starcross-579 strains (six hens per strain) were fed diets supplemented with 0 (control), 2, 4, 6, 8, or 10% sun-dried garlic paste for 6 wk. The...

The study aimed to determine evaluate the use of sorghum as a substitute for maize in laying quail diet and its effect on performance quality eggs produced best levels lutein (Marigold flower extract) canthaxanthin inclusion based Japanese feed well influence storage time eggs. A total 680 quails (Coturnix coturnix japonica), with 64 weeks age was distributed 4 × x4 factorial + 1 control scheme...

Egg-tempera painting is a pictorial technique widely used in the Middle Ages, although poorly studied its physico-chemical aspects until now. Here we show how NMR relaxometry and rheology can be combined to probe egg-tempera paints shed new light on their structure behavior. Based recipes of 15th century, model formulations with egg yolk green earth have been reproduced characterize physicochem...

It is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and...

The aim of this study was to compare the quality and physicochemical characteristics of blue-shelled eggs (BE) and conventional eggs (CE). Proximate composition, quality, pH value, shell color, collagen content, fatty acid composition, total cholesterol, α-glucosidase inhibition activity, and antioxidation activity were determined. The proximate composition, general qualities, and pH values of ...

This trial was conducted to evaluate the effects of high-dose daidzein supplements on laying performance, egg quality and antioxidation in laying hens during the late laying period. Seven hundred sixty eight 55-wk-old Hyline Brown were randomly assigned to four groups with 8 replicates of 24 birds each (192 laying hens per group) and fed diets supplemented with 0 (control), 10mg/kg, 50mg/kg and...

this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...
