大豆异黄酮对产蛋后期蛋鸡卵巢机能的影响
Effects of Daidzein on Ovary Function of Hens during the Late Laying Period
摘要
Abstract
This study was conducted to investigate the possible improvement effects of daidzein ( Da) on ovary function of hens during the late laying period. Four hundred and fifty 70⁃week⁃old Hy⁃Line Brown laying hens were randomly allocated to 3 groups with 5 replicates per group and 30 chickens per replicate. There were 3 di⁃ets in this experiment consisting of one basic diet and 2 test diets supplemented with 10 or 15 mg/kg Da, re⁃spectively. The experiment lasted for 28 d. The results showed as follows:1) dietary Da supplementation sig⁃nificantly increased the laying rate (P<0.05), did not significantly impact on secretion levels of luteinizing hormone, follicle⁃stimulating hormone and progesterone ( P>0.05) , but 15 mg/kg Da supplementation group significantly increased the secretion levels of estradiol, β⁃endorphin and vitellogenin ( P<0.05) . 2) Compared with the control group, 10 mg/kg Da supplementation group did not significantly influence the numbers of hi⁃erarchical yellow follicles, smaller yellow follicles and large white follicles, as well as the atresia rates of all kinds of follicles (P>0.05), but 15 mg/kg Da supplementation group significantly increased the numbers of each follicles ( P<0.05) , and extremely significantly increased the numbers of large white follicles and primary follicles ( P<0.01) , meanwhile significantly reduced the atresia rates of smaller yellow follicles, large white follicles and secondary follicles ( P<0.05) . 3) The 15 mg/kg Da supplementation group extremely significant⁃ly increased the superoxide dismutase activity in plasma and ovary of hens (P<0.01), and significantly in⁃creased the superoxide dismutase activity in liver ( P<0.05) . It is concluded that Da can improve the production and ovarian function of laying hens, and the principle is related to the increasing secretion of estradiol and β⁃endorphin and the improvement of resistance to oxidation. There are some differences between two kinds of Da, and 15 mg/kg may get the better effect than 10 mg/kg in our study.关键词
