Egg yolk oil is a natural source of bioactive compounds such as unsaturated fatty acids, oil soluble vitamins, pigments and others. Bioactive compound content in egg yolk oil depends from its content in eggs, from which oil was extracted. Many studies show that bioactive compound content in egg is correlated to the content of these compounds in hen feed, but there is also an opinion that hen ho...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

The work on liver lecithins by Levene and Ingvaldsen’ and by Levene and Simms,z has shown the existence of lecithins which are distinguished from one another by the nature of their unsaturated fatty acids. There were isolated from liver lecithin, two unsaturated fatty acids, oleic and arachidonic, as well as two saturated acids, palmitic and stearic. Hence on the basis of the present findings i...

The objective of this study was to determine the effects of diet supplemented with marigold on egg yolk fatty acid composition and egg quality parameters. Sixty hens were assigned into three groups and fed diets supplemented with 0 (control), 10 g kg(-1), or 20 g kg(-1) marigold for 42 days. Eggs collected at the 6th week of the study were analyzed for fatty acid analysis. Laying performance, e...

Cross-sectional study of quail eggs was conducted to evaluate the nutritional compositions of carbohydrate, fat, protein, calories, vitamin, minerals and sex hormones. The results showed that average of each whole quail egg weight was 10.67 g. Their contents of ash, carbohydrate, fat, protein and moisture were 1.06, 4.01, 9.89, 12.7 and 72.25 g 100g -1 , respectively. Total energy in calories o...

A total of 216 Brown Dwarf laying hens (1.62 +/- 0.06 kg BW and 60 wk old) were fed 1 of 3 corn-soybean meal-based diets containing 0, 2.5, or 5.0% conjugated linoleic aicd (CLA) to explore its effects on the fatty acid composition of egg yolk, plasma, and liver as well as hepatic stearoyl-coenzyme A desaturase-1 (SCD-1) activity and its mRNA gene expression. Four hens were placed in wired-floo...

Based on evidence from rodent models, it was hypothesized that furan fatty acids found in corn would inhibit reproduction in the laying hen. An isomeric mixture of furan fatty acids [9, (12)-oxy-10,13-dihydroxystearic acid and 10, (13)-oxy-9,12-dihydroxystearic acid] was administered for a period of 3 wk via the diet (1 and 3 ppm) at levels greater than those in corn to 20-wk-old pullets. There...

Hen’s egg has long history as a food. It contains a great variety of nutrients to sustain both life and growth. Egg provides an excellent, inexpensive and low calorie source of highquality proteins. Moreover, Eggs are a good source of several important nutrients including protein, total fat, monounsaturated fatty acids, polyunsaturated fatty acids, cholesterol, choline, folate, iron, calcium, p...
