【摘要】：本試驗旨在探究富鍺酵母菌培養(yǎng)物對產(chǎn)蛋高峰期的海蘭褐殼蛋雞抗氧化性能、血清生化指標和免疫指標的影響。試驗將240只健康無病、日齡及體況較一致的海蘭褐殼蛋雞隨機分為對照組和試驗組,每組120只,各12個重復,每個重復10只。其中試驗組日糧中添加0.2%富鍺酵母菌培養(yǎng)物,對照組飼喂基礎(chǔ)日糧;預飼期7 d,正式試驗42 d。結(jié)果顯示:與對照組相比,試驗組血清中總膽固醇含量降低了17.24%(P0.05);甘油三酯含量降低了19.73%(P0.05);尿素氮含量降低了22.68%(P0.05);IgG含量提高了5.39%(P0.05);SOD活性提高了12.18%(P0.01);MDA活性降低了10.06%(P0.05);蛋雞肝臟中SOD、GSH-Px活性分別提高了21.46%(P0.01)和11.16%(P0.05);蛋黃中MDA活性降低了17.78%(P0.01)。試驗表明:日糧中添加0.2%富鍺酵母菌培養(yǎng)物可顯著提高蛋雞抗氧化性能及免疫性能。
[Abstract]:The purpose of this experiment was to investigate the effects of germanium enriched yeast culture on the antioxidant activity, serum biochemical index and immune index of Hailan brown shell laying hens during the peak period of egg production. 240 healthy, disease-free, day-old Hailan brown shell hens were randomly divided into two groups: control group (n = 120) and experimental group (n = 10). In the experiment group, 0.2% germanium enriched yeast culture was added to the diet, while the control group was fed the basal diet, and the pre-feeding period was 7 days, the formal test was 42 days. The results showed that: compared with the control group, In the test group, the total cholesterol content in serum decreased 17.24% P0.05, triglyceride reduced 19.73% P0.05, urea nitrogen decreased 22.68% P0.05G and 5.39% P0.05 + P0.05 + SOD activity increased 12.18% P0.01MDA activity decreased 10.06% P0.05%, the activity of SOD in liver increased 21.4646 P0.05) and 11.16% P0.05, respectively, and the activity of P0.05 in the liver of the control group was increased by 21.46P0.05) and 11.165T, respectively, and the activity of P0.05 in the liver of the test group was increased by 10.06% P0.05, while the activity of SOD in the liver was increased by 21.4646 (P0.01) and 11.16% (P0.05), respectively. The activity of MDA in yellow decreased 17.78% (P 0.01). The results showed that 0.2% germanium enriched yeast culture could significantly improve the antioxidant and immune performance of laying hens.
