【摘要】：為研究酵母硒對(duì)蛋雞血清酶活性及抗氧化能力的影響,試驗(yàn)選用1 000只280日齡的海蘭褐殼蛋雞,隨機(jī)分為5組,每組5個(gè)重復(fù),每個(gè)重復(fù)40只,分別為基礎(chǔ)飼糧組,以及0.1,0.2,0.3和0.4mg/kg酵母硒添加水平組,試驗(yàn)期40d。結(jié)果表明:與對(duì)照組相比,各試驗(yàn)組均可顯著提高血清ALP和LDH活性(P0.05),并顯著降低CK活性(P0.05);與對(duì)照組相比,飼糧添加0.2,0.4mg/kg酵母硒均可顯著提高血清SOD活性(P0.05),其他試驗(yàn)組SOD活性與對(duì)照組無(wú)顯著性差異(P0.05);各試驗(yàn)組GSH-Px和T-AOC水平均顯著高于對(duì)照組(P0.05),而血清MDA含量均顯著低于對(duì)照組(P0.05)。試驗(yàn)結(jié)果提示,酵母硒可提高蛋雞抗氧化能力,且以添加0.3,0.4mg/kg為宜。
[Abstract]:In order to study the effect of yeast selenium on serum enzyme activity and antioxidation ability of laying hens, 1 000 Hailan brown shell laying hens aged 280 days were randomly divided into 5 groups, 5 replicates in each group and 40 in each, respectively, as basal diet group. The results showed that compared with the control group, the serum ALP and LDH activities were significantly increased in each experimental group, and the activity of CK was significantly decreased in the experimental group, compared with the control group, and the activity of CK was significantly decreased in the experimental group. The results showed that the serum ALP and LDH activity of the experimental group were significantly higher than that of the control group, and that of the control group was significantly lower than that of the control group. Dietary supplementation of 0.2 mg / kg yeast selenium significantly increased serum SOD activity (P0.05N), but there was no significant difference in SOD activity between the other trial groups and the control group (P 0.05). The levels of GSH-Px and T-AOC in each trial group were significantly higher than those in the control group (P 0.05), and the serum MDA levels were significantly lower than those in the control group. The results of the test indicate that, Yeast selenium can improve the antioxidant ability of laying hens, and it is suitable to add 0.3g / kg of 0.3g / kg.
