【摘要】：试验旨在研究饲粮添加白术多糖、枯草芽孢杆菌对育成期蛋鸡生长性能和血清免疫指标的影响。选用体重相近、健康的11周龄海兰褐蛋鸡480只,随机分成12组,每组4个重复,每个重复10只。采用4(白术多糖:0、0.2%、0.4%和0.6%)×3(枯草芽孢杆菌:0、250 mg/kg和500 mg/kg)因子设计试验。试验期为7周,其中预试期1周,正试期6周。结果显示:(1)饲粮中添加白术多糖对育成期蛋鸡的平均日采食量和血清Ig M含量无显著影响(P0.05),但可以显著提高其末体重、平均日增重和血清Ig A、Ig G含量(P0.05),降低料重比(P0.05);(2)饲粮中添加枯草芽孢杆菌对育成期蛋鸡的末体重、平均日采食量和料重比及血清Ig A含量均无显著影响(P0.05),但可以显著提高其平均日增重(P0.05),并提高血清Ig G和Ig M含量(P0.05);(3)白术多糖和枯草芽孢杆菌的互作效应对育成期蛋鸡的平均日采食量和血清Ig A、Ig M含量无显著影响(P0.05),但可显著提高其末体重、平均日增重和血清Ig G含量,降低料重比(P0.05)。试验表明,白术多糖和枯草芽孢杆菌两者互作对育成期蛋鸡的生长性能和血清免疫指标有协同作用,且以添加0.4%白术多糖和250 mg/kg枯草芽孢杆菌组的效果较佳。
[Abstract]:The purpose of the experiment was to study the effects of dietary Atractylodes macrocephala polysaccharides and Bacillus subtilis on growth performance and serum immune index of laying hens.Four hundred and eighty Hailan brown layers of similar weight and healthy 11 weeks were randomly divided into 12 groups with 4 replicates in each group and 10 layers in each group.The experiment was designed with 4 (Atractylodes macrocephala polysaccharide 0: 0. 2% and 0. 6%) 脳 3 (Bacillus subtilis: 0 250 mg/kg and 500 mg / kg) factor.The trial period was 7 weeks, in which the pretest period was 1 week and the positive trial period was 6 weeks.The results showed that the addition of Atractylodes macrocephala polysaccharides in diet had no significant effect on the average daily intake and serum IgM content of laying hens, but could significantly increase the end weight of laying hens.The average daily gain (ADG) and serum IgA Ig G content (P0.05G) decreased the feed / weight ratio (P0.05G / kg).) the supplementation of Bacillus subtilis in diet on the end weight of laying hens at growing stage was studied.The average daily feed intake and serum IgA Ig M content of laying hens had no significant effect on P0.05, but they could significantly increase their end weight.The average daily gain (ADG) and serum IgG content decreased the feed weight ratio (P < 0.05).The results showed that the interaction of Atractylodes macrocephala polysaccharides and Bacillus subtilis had synergistic effects on growth performance and serum immune index of laying hens, and the effects of adding 0.4% Atractylodes macrocephala polysaccharide and 250 mg/kg Bacillus subtilis were better.
