abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...

in this experiment, a total of 128 hy-line w36 hens at 63 weeks of age were used. the hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. all birds were housed in commercial cages, had ad libitum access ...

this study aimed to decrease the cholesterol content of egg yolk of laying hens through inclusion of barley malt rootlets in the diets. forty-two, 54-week-old, lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 25.5 or 51.1g barley malt rootlets/kg. inclusion of barley malt rootlets at 25.5 or 51.1g/kg diet significantly de...

The correlation of yolk cholesterol and yolk fat concentrations of egg from the pedigreed Athens-Canadian Randombred control population with the percentage of abdominal fat (AF) and feed conversion ratio (FCR) of their progeny were studied. The average yolk cholesterol, yolk fat, and AF were 20.3 mg/g yolk, 244 mg/g yolk, and 1.64%, respectively. The phenotypic correlation of both yolk choleste...

an eight week study was conducted to investigate the effect of inclusion of tomato waste meal in layer diets on laying performance, egg quality and lipid profile as a means to reduce feed cost and pollution. four laying diets containing tomato waste meal (twm) at four levels of 0, 3, 6 or 9% were assigned randomly to 4 groups of 40 birds divided among four replicates of 10 birds in each dietary...

The objective of this study was to investigate the deposition rule of yolk cholesterol in Lushi Green-shelled and Silky Fowl layers. A total of 90 layers of each breed were selected at an age of 15 to 51 weeks. Productive performance was recorded on a weekly basis, whereas yolk cholesterol was determined at 4-week intervals from 21 to 51 weeks of age. The average yolk cholesterol content of Sil...

This experiment was conducted to measure the effects of olive leaf powder on performance, egg yield, egg quality and yolk cholesterol level of laying hens. A total of 120 Lohmann Brown laying hens of 22 weeks old were used in this experiment. The birds were fed on standard layer diets containing 0, 1%, 2%, or 3% olive leaf powder for 8 weeks. Egg weight and yield were recorded daily; feed intak...

this experiment was conducted to investigate the effects of various levels of cichorium intybus andcopper on performance and egg yolk cholesterol. total of 324 layer hens (hy-line w-36) were used in arandomized complete blocks with nine treatments, three replications of 12 birds in each from 38 to 50weeks of age. experimental diets include control, four levels of copper (150, 200, 250 and 300 m...

In recent years, the consumer’s desire for healthier foods has increased the demand for animal products containing low cholesterol and enriched with omega-3 fatty acids. In response to the perceived need, poultry researchers have focused on reducing egg yolk cholesterol to satisfy the health conscious of consumers. The present study was conducted to determine the effects of dietary forage legum...
