外文摘要：Two experiments were carried out to study the effect of in ovo manganese (Mn) injection on the embryonic development, antioxidation, hatchability, and performances of offspring broilers under normal temperature (NT) and high temperature (HT). Experiment 1 was conducted to investigate the effect of in ovo Mn injection on the embryonic hatchability of Arbor Acres broiler breeders. On D 9 of incubation, a total of 684 fertilized eggs were randomly allocated to 6 treatments: the non-injected positive control (niPC) and treatments injected with 0 (the negative control, iNC), 6.25, 12.5, 25.0, or 50.0 mg Mn/egg as Mn sulfate. Experiment 2 was conducted to investigate the effect of in ovo Mn injection on the embryonic development, antioxidation and performance of offspring broilers under NT and HT. A total of 792 fertilized eggs were randomly allocated to 6 treatments in a 1 (niPC) + 1 (iNC) + 2 (injected Mn sources: Mn sulfate and Mn proteinate) pound 2 (injected Mn levels: 12.5 and 25.0 mg/egg) factorial arrangement during the embryonic stage and D1 to 28 at NT. Then, 288 birds were allotted to 12 treatments in a 6 (the above embryonic treatments) pound 2 (environmental temperatures: NT-22. vs HT-34.) factorial arrangement from D 29 to 42. The results showed that Mn injection affected (P < 0.03) the hatchability and the maximum level of in ovo injected Mn was 25.0 mg Mn/egg. The Mn injection upregulated (P < 0.05) Mncontaining superoxide dismutase mRNA expression in the embryonic heart compared to the iNC. Hyperthermia decreased (P < 0.05) ADG and ADFI, breast muscle percentage, plsma alkaline phosphatase activity, and red color values of breast and thigh muscles, but increased (P < 0.05) F/G, plasma aspartate aminotransferase and lactic dehydrogenase activities, total cholesterol, uric acid and triiodothyronine contents, abdominal fat, light values of breast and thigh muscles of offspring broilers. The results suggest that in ovo Mn injection can enhance antioxidant ability in the chick embryonic heart.
