Antioxidant systems in chick embryo development. Part 1. Vitamin E, carotenoids and selenium
Chick viability is known to be an important factor determining profitability of the poultry industry. Chick embryo tissues contain a high proportion of highly polyunsaturated fatty acids in the lipid fraction and therefore need antioxidant defence. The antioxidant system of the developing embryo and newly hatched chick includes the antioxidant enzymes (superoxide dismutase, glutathione peroxida...

متن کاملComparison of Natural and Synthetic Carotenoids: Effect on Yolk Colour and Oxidative Stability of Yolk Lipids
Two experiments were performed to evaluate the effect of synthetic and natural carotenoids on the daily output of eggs and some parameters of their quality. The hens were fed a control diet and diets supplemented with synthetic carotenoids Carophyll Red and Carophyll Yellow, lutein, algae Chlorella, and mustard meal. Carotenoids had no effect on hen-day egg production. Both synthetic and natura...
