【摘要】：為篩選桑葉適宜禽類飼料用的桑品種及明確桑葉發(fā)酵后的飼用效果,將桑品種大10、抗10、吳堡桑、湘7920的桑葉以及大10的發(fā)酵桑葉分別按照一定比例(質(zhì)量分數(shù)3%)添加至胡須雞的日糧中,調(diào)查桑葉飼料對胡須雞生長性能、屠宰性能、肉品質(zhì)、抗氧化指標的影響。與普通日糧飼養(yǎng)對照組相比,抗10桑葉飼料組胡須雞的平均日增體質(zhì)量極顯著降低(P0.01),大10桑葉飼料組、抗10桑葉飼料組、湘7920桑葉飼料組胡須雞的日采食量均顯著降低(P0.05)。各品種桑葉飼料組胡須雞的屠宰性能、肉品質(zhì)指標與對照組比較以及各品種桑葉飼料組之間比較均無顯著差異(P0.05)。與對照組相比,抗10桑葉飼料組胡須雞血清中的谷胱甘肽過氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性分別呈極顯著(P0.01)和顯著(P0.05)上升,過氧化氫酶活性、肝臟丙二醛(MDA)含量分別呈顯著(P0.05)和極顯著(P0.01)下降;吳堡桑桑葉飼料組胡須雞血清中的SOD活性顯著上升(P0.05);大10發(fā)酵桑葉飼料組胡須雞血清中的SOD活性極顯著上升(P0.01),肝臟MDA含量顯著下降(P0.05)。綜合各項指標,吳堡桑桑葉飼料和大10發(fā)酵桑葉飼料對胡須雞的生長性能無影響或有一定程度提高,2組桑葉飼料能明顯改善胡須雞血清、肝臟的抗氧化能力,飼用效果較好。
[Abstract]:In order to screen mulberry varieties suitable for poultry feed and to determine the feeding effect of mulberry leaves after fermentation, mulberry varieties were selected as big 10, resistant 10 and Wubao mulberry varieties. The mulberry leaf of Xiang 7920 and fermented mulberry leaf of Big 10 were added to the diet of bearded chicken according to a certain proportion (3% by mass fraction). The effects of mulberry leaf feed on growth performance, slaughter performance, meat quality and antioxidant index were investigated. Compared with the normal diet control group, the average daily body weight (ADG) of the mustache chickens in the anti-10 mulberry leaf feed group was significantly decreased (P0.01), and the daily feed intake of the bearded chickens in the anti-10 mulberry leaf feed group, the anti-10 mulberry leaf feed group and the Xiang 7920 mulberry leaf feed group were significantly decreased (P0.05). There was no significant difference in slaughtering performance, meat quality index between mulberry leaf feed group and control group and between mulberry leaf feed group and control group (P0.05). Compared with the control group, the activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in serum of the control group were significantly increased (P0.01) and significantly (P0.05). The content of malondialdehyde (MDA) in liver decreased significantly (P0.05) and extremely significantly (P0.01). The serum SOD activity of mulberry leaf feed group increased significantly (P0.05), the serum SOD activity of mulberry leaf feed group increased significantly (P0.01), and the MDA content of liver decreased significantly (P0.05). The results showed that Wubu mulberry leaf feed and Da-10 fermented mulberry leaf feed had no effect on the growth performance of mustache chickens or could improve the antioxidation ability of serum and liver of the two groups to a certain extent, and the feeding effect was better.
