Supplementation of laying-hen feed with palm tocos and algae astaxanthin for egg yolk nutrient enrichment.

Adding supplements to hen feed can increase egg nutritional value. Astaxanthin, tocotrienols, and tocopherols are potent antioxidants that provide health benefits to humans. We hypothesized that the addition of these nutrients to hen feed would result in an increased nutrient content in egg yolk with minimum changes in functional properties. Laying hens (Hy-Line W-36 breed) were fed four diets ...

Egg Iron Enrichment in Response to Various Levels of Pomegranate by-Product in Laying Hen Diet

The present study was conducted to investigate the effects of different levels of pomegranate by- product (PBP) on performance, egg quality and blood parameters in laying hens. A total of 144 Bobze layer hens from 44 to 56 weeks during 12 weeks were randomly assigned into 4 treatments including 0 (control, corn and soy bean meal), 4, 8 and 12% of PBP, with 4 replicates and 9 layers in each. Res...

The composition of triglycerides from liver, egg yolk and adipose tissue of the laying hen.

The composition of the triglycerides of liver, egg yolk and adipose tissue of laying hens fed on a standard diet were investigated by using argentation thin-layer chromatography to separate the triglycerides according to their degree of unsaturation. About 40% of liver triglycerides consisted of one saturated and two monoenoic fatty acids. Triglycerides containing linoleate were more abundant i...

The enrichment of eggs with folic acid through supplementation of the laying hen diet.

In light of evidence supporting a need for humans to increase their dietary folate intakes, experiments were conducted to evaluate the extent to which egg folate levels could be increased. In Study 1, Hyline W36 hens (n = 6/diet) received a barley-based diet, containing 0 or 10 mg/kg of crystalline folic acid, to establish the potential for folate incorporation into table eggs. In Study 2, 70 h...

Lycopene incorporation into egg yolk and effects on laying hen immune function.

Carotenoids are partially responsible for the colors of plants and when consumed by humans and animals are deposited into tissues (e.g., skin and egg yolk in laying hens) and may have health benefits. Because carotenoids are more available when consumed from egg yolk sources than vegetables, this research examined the ability of the laying hen to deposit dietary lycopene, a carotenoid that impa...
