【摘要】：为筛选桑叶适宜禽类饲料用的桑品种及明确桑叶发酵后的饲用效果,将桑品种大10、抗10、吴堡桑、湘7920的桑叶以及大10的发酵桑叶分别按照一定比例(质量分数3%)添加至胡须鸡的日粮中,调查桑叶饲料对胡须鸡生长性能、屠宰性能、肉品质、抗氧化指标的影响。与普通日粮饲养对照组相比,抗10桑叶饲料组胡须鸡的平均日增体质量极显著降低(P0.01),大10桑叶饲料组、抗10桑叶饲料组、湘7920桑叶饲料组胡须鸡的日采食量均显著降低(P0.05)。各品种桑叶饲料组胡须鸡的屠宰性能、肉品质指标与对照组比较以及各品种桑叶饲料组之间比较均无显著差异(P0.05)。与对照组相比,抗10桑叶饲料组胡须鸡血清中的谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性分别呈极显著(P0.01)和显著(P0.05)上升,过氧化氢酶活性、肝脏丙二醛(MDA)含量分别呈显著(P0.05)和极显著(P0.01)下降;吴堡桑桑叶饲料组胡须鸡血清中的SOD活性显著上升(P0.05);大10发酵桑叶饲料组胡须鸡血清中的SOD活性极显著上升(P0.01),肝脏MDA含量显著下降(P0.05)。综合各项指标,吴堡桑桑叶饲料和大10发酵桑叶饲料对胡须鸡的生长性能无影响或有一定程度提高,2组桑叶饲料能明显改善胡须鸡血清、肝脏的抗氧化能力,饲用效果较好。
[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.
