低温环境下饲粮核黄素添加水平对蛋鸭生长发育、免疫器官及抗氧化功能的影响
Effects of Riboflavin Supplementation on Growth, Immune Organ and Antioxidant Function of Laying Ducks at Low Ambient Temperatures
摘要
Abstract
The experiment was conducted to study the effects of riboflavin supplementation on growth and development, immune organ and anti-oxidative ability of laying ducks at low ambient temperature. Two factors (temperature x riboflavin) interactive experimental design was used in the experiment. The ambient temperatures were (2 ± 1) °C and (18 ± 1) °C, and supplemental levels of riboflavin in a basal diet were 4, 16 and 32 mg/kg, respectively. A total of 144 laying ducks (Jinding duck, female, 12 weeks old) were randomly allotted to 6 treatments with 6 replicates per treatment and each replicate comprised 4 ducks. The experiment lasted for 42 days. The results showed that ovary weight index and oviduct length index were significantly affected by the interaction between ambient temperature and riboflavin (P <0.05), however, the interaction between ambient temperature and riboflavin has no effect on the oviduct weight index (P >0.05). Immune organ indices were significantly affected by the interaction between ambient temperature and riboflavin ( P < 0.05). There were no significant differences in serum total antioxidant capacity, the activities of glutathione reductase and malondialdehyde concentration (P >0. 05). However, catalase and total superoxide dismutase activity were significantly affected by the interaction between ambient temperature and riboflavin (P<0.05). In conclusion, low ambient temperature is not conducive to growth and development of laying ducks, and appropriately increasing dietary riboflavin level in diets can release cold stress response to a certain extent.关键词
