【摘要】：本试验旨在研究益生菌对罗曼蛋雏鸡生长性能、血清生化指标、免疫器官指数的影响。选取1日龄健康,体重相近的罗曼褐蛋雏鸡432只,随机分成A、B、C、D 4个组,每组6个重复,每个重复18只鸡。A组为对照组,饲喂基础日粮;B、C、D为试验组,分别在基础日粮中添加粪肠球菌制剂、嗜酸乳杆菌制剂、乳双歧杆菌制剂。结果显示:(1)与A组相比,B、C、D组各周龄末雏鸡体重、平均日采食量(ADFI)、平均日增重(ADG)随试验进行均表现出先下降后上升的趋势,在6周龄末时达到最佳,B、C、D组的雏鸡体重和ADG分别较A组显著提高了6.9%、7.9%、6.3%和17.2%、18.7%、12.2%(P0.05),ADFI较A组极显著提高了9.2%、13.5%、10.0%(P0.01)。全期B、C、D组ADFI和ADG较A组分别极显著提高了5.3%、7.0%、6.4%和7.6%、8.6%、6.8%(P0.01)。试验组各周龄的料重比(F/G)无显著差异(P0.05)。(2)与A组相比,D组尿素氮(BUN)含量显著降低了34.8%(P0.05),B、C组BUN含量下降了8.7%、8.7%,但较A组差异不显著(P0.05),其余血清生化指标均无显著差异(P0.05)。(3)B、C、D与A组间的免疫器官指数均无显著差异(P0.05),但B、C、D组的胸腺指数分别比A组提高了3.5%、12.3%、1.8%。综上,日粮中添加益生菌可改善雏鸡的生长性能。
[Abstract]:The purpose of this study was to study the effects of probiotics on growth performance, serum biochemical index and immune organ index of Rohmann egg chicks. 432 Roemannian brown egg chicks, healthy and of similar body weight, were randomly divided into 4 groups, 6 repeats in each group and 18 chickens in group A as control group. Enterococcus faecalis, Lactobacillus acidophilus and Lactobifidobacterium were added to the basal diet. The results showed that compared with group A, the body weight, average daily intake (ADFI) and average daily gain (ADG) of chicks at the end of each week were decreased first and then increased with the experiment. The body weight and ADG of chicks in group D at the end of 6 weeks of age were significantly higher than those in group A by 6.9% and 17.2%, respectively. Compared with group A, the ADFI of group A was significantly higher than that of group A. The ADFI and ADG in group D were significantly higher than those in group A (5.3%) and 7.6% (P 0.01), respectively. There was no significant difference in the feed weight ratio (F / G) of the test group (P 0.05) compared with group A (P < 0.05) the content of BUN in group D was significantly lower than that in group A (P < 0.05). The content of BUN in group C decreased by 8.7%, but there was no significant difference between group A and group A (P 0.05), and there was no significant difference between group A and group A in terms of serum biochemical indexes (P 0.05), and the content of BUN in group C was significantly lower than that in group A (P 0.05), but there was no significant difference between group A and group A (P > 0.05). There was no significant difference in the immune organ index between group A and group A, but the thymus index of group B CnD was higher than that of group A by 3.5% and 12.3%, respectively. In conclusion, adding probiotics to the diet can improve the growth performance of chicks.
