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...

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...

Japanese Quails were used to evaluate the effects of dietary supplementation with vitamin E (dl-a-tocopheryl-acetate), lycopene, and their combination on egg production, egg quality, concentrations of malondialdehyde (MDA), vitamin E, A and cholesterol in serum and egg yolk. Quails (n = 120; 55 d old) were divided into four groups (n = 30/group) and fed a basal diet or the basal diet supplement...

The effects of natural dietary carotenoid supplementation of the maternal diet (tomato powder and marigold extract) on transfer to the egg yolk and on the development of the antioxidant system of the young quail liver in early postnatal life were investigated. Sixty Japanese quail (Coturnix coturnix japonica) were allocated to four treatment groups, each with three replicates consisting of four...

Background: This study was conducted to investigate the effects of natural and synthetic sources lycopene on performance, egg quality some blood characteristics Japanese quail layers. Methods: The 252 eight-week-old hens were randomly divided into seven treatments with three replication. first treatment fed basal diet (control). Second third given diets containing tomato fruit powder (TOM) at a...

The level of consumers’ satisfaction with the quality edible chicken eggs is determined, in particular, by attractive appearance yolks and their content biologically active substances that have functional properties. Such compounds include carotenoids astaxanthin lycopene, which can be deposited yolks, provide pigmentation, as powerful antioxidants, affect stability fatty acid composition lipid...

Background: Nowadays, radiotherapy is used effectively for treatment of head and neck cancers. Mucositis is one of the most important side effects of radiotherapy. Radio-protective agents protect tissues and cells against the adverse effects due to ionizing radiation and cleave radiation-induced free radicals. Lycopene as a potent antioxidant protects cells against oxidative damage by free radi...
