【摘要】：试验旨在研究日粮中添加苦玄参提取物对广西麻鸡血清生化指标及免疫功能的影响。选用1日龄广西麻鸡500羽,随机分为5组(A、B、C、D、E组),每组设5个重复,每个重复20羽。其中A、B、C组为试验组,分别在基础日粮中添加0.70%,0.35%和0.175%的苦玄参提取物;D组为阳性药物对照组,在基础日粮中添加0.01%硫酸黏菌素预混料;E组为空白对照组,饲喂基础日粮,预试期3d,正试期49d。于21、35和49日龄时分别从每组抽取10羽试验鸡进行心脏采血,测定血清生理生化及免疫指标。结果显示:与E组相比,日粮添加苦玄参提取物对鸡的血清TP、GLU含量无显著影响(P0.05);但21和35日龄时,A、B、C组的TBILI含量均极显著或显著低于E组(P0.01;P0.05);35日龄时,A、B、C组的血清AKP活性均极显著高于E组(P0.01),C组的GOT活性在21和35日龄时显著高于E组(P0.05);49日龄时,A、B、C组的IgG和B、C组IL-2含量均显著或极显著低于E组(P0.05;P0.01),B组T-AOC显著高于E组(P0.05),A、B、C组血清GSH含量均显著高于E组(P0.05)。由此可知,日粮中添加的苦玄参提取物显著降低了广西麻鸡的血清TBILI含量,并在一定程度上降低了IgG、IL-2和IL-6含量,提高了AKP和GOT活性及T-AOC和GSH含量。综合考虑,以0.35%的添加量效果最好。
[Abstract]:The experiment was conducted to study the effects of extracts of Radix Sophora Radix Sophora on serum biochemical indexes and immune function of Guangxi chicken. 500 feathers of Guangxi chicken in 1 days of age were randomly divided into 5 groups (A, B, C, D, E group), each group had 5 repetitions and 20 plumes, each of which was A, B, and C as the experimental group, and 0.70%, 0.35% and 0.175% of the Sophora dauri were added to the basal diet. The D group was used as the positive drug control group, and the basal diet was added to the basal diet with 0.01% colysin sulphate premixture, and the E group was a blank control group. The basal diet was fed, the pre trial period 3D was fed, and the positive 49d. was extracted from each group of 10 feathers from each group at the 21,35 and 49 days of age to collect blood from the heart and determine the serum physiological and biochemical and immune indexes. The results showed that the phase of the serum was compared with the E group. There was no significant effect on serum TP and GLU content in chicken serum (P0.05), but the TBILI content in A, B and C groups was significantly or significantly lower than that of E group (P0.01; P0.05) at 21 and 35 days old, while 35 days old, A, B and 35 days of age were significantly higher than those in the group of 21 and 35; 4 At 9 days of age, the content of IL-2 in group A, B and C was significantly lower than that of group E (P0.05; P0.01), and B group T-AOC significantly higher than that of the group (P0.05). The contents of IgG, IL-2 and IL-6 increased the activity of AKP and GOT and the content of T-AOC and GSH. Considering the addition of 0.35%, the best effect was obtained.
