摘要: Two trials were designed to investigate the impacts of egg storage time and maternal dietary vitamin E (VE) supplementation on growth performance antioxidant capacity progeny chicks. In total 512 Ross 308 broiler breeder hens (71-wk-old) assigned 2 VE treatments (6 100 mg/kg) for 14 wk. Progeny chicks used in 1 originated from eggs laid at week 10 (stored 0 d) 8 d), 12 respectively. The 4 groups trial consisted levels (0 d). mg/kg), sex (male female). 1, decreased body weight, liver superoxide dismutase 21-day-old offspring (P < 0.05), weight gain feed intake 21 d 0.05); increased serum malonaldehyde (MDA) 7-day-old ratio feed: (F/G) 7 0.05). Maternal (100 vs. 6 F/G 2, 42-day-old offspring, 22 42 MDA 21- reduced Interactively, stored but not that unstored two trials. It can be concluded (14 while could partly alleviate reduction (except performance) induced by early phase post-hatch.
