Effects of Dietary Vitamin E and Selenoyeast on Laying Performance, Hatching Performance and Vitamin E and Selenium Deposition in Egg of Yellow?Feathered Broiler Breeders
摘要
Abstract
The effects of dietary vitamin E ( VE) and selenoyeast on laying performance, hatching perform?ance and vitamin E and selenium ( Se) deposition in egg of yellow?feathered broiler breeders were studied. A 3×3 double factorial design with three supplemented levels of vitamin E (0, 20 and 40 IU/kg) and three sup?plemented levels of Se (0, 0.15 and 0.30 mg/kg) was used. Eight hundred and sixty four 32?week?old fast?growing Lingnan yellow?feathered parental broiler breeder hens were randomly assigned to nine groups with six replicates per group and sixteen hens per replicate according the similar laying rate and body weight. The nine groups were VE0Se0 group, VE0Se0.15 group, VE0Se0.30 group, VE20Se0 group, VE20Se0.15 group, VE20Se0.30 group, VE40 Se0 group, VE40 Se0.15 group and VE40 Se0.30 group, respectively. The experiment lasted for 8 weeks. The results showed as follows:1) dietary vitamin E and Se levels had no significant effects on weight gain, average daily egg mass, the ratio of feed to egg, average egg weight, laying rate, broken egg rate, un?qualified egg rate of yellow?feathered broiler breeders (P>0.05). 2) Dietary vitamin E and Se levels had no significant effects on egg long diameter, egg short diameter, albumen height, yolk color, Haugh unit, yolk weight, eggshell weight, eggshell thickness of yellow?feathered broiler breeders ( P>0.05) . 3) Dietary vitamin E and Se levels had no significant effects on healthy chick birth weight, hatchability, altricial rate, fertilization rate of yellow?feathered broiler breeders (P>0.05). 4) Dietary vitamin E level had significant effect on the content of malondialdehyde ( MDA) in plasma of yellow?feathered broiler breeders ( P<0.05) . The content of MDA in plasma had a decreasing tendency with the increase of dietary vitamin E level, and the content of MDA in plasma at 40 IU/kg vitamin E supplemented level was significantly lower than that at 0 IU/kg vitamin E supplemented level ( P<0.05) . Dietary vitamin E and Se levels had significant interaction on the content of MDA in plasma (P<0.05), and the content of MDA in plasma in VE40Se0 group was significantly lower than that in VE0Se0.15 and VE0Se0.30 groups (P<0.05). 5) The contents of vitamin E and Se in egg of yellow?feath?ered broiler breeders was significantly increased with the increase of dietary vitamin E and Se levels ( P<0.05) , and dietary vitamin E and Se levels had significant interaction on the contents of vitamin E and Se in egg ( P<0.05) . In conclusion, vitamin E can improve the antioxidation level of yellow?feathered broiler breed?ers, and dietary vitamin E and Se levels had significant effects on the contents of vitamin E and Se in egg ( P<0.05). It is suggested that corn?soybean meal diet of yellow?feathered broiler breeders do not need adding vita?min E and Se without any stress factors and without using feedstuffs in Se deficiency area.关键词
