摘要

本试验旨在研究不同环境下玉米-豆粕型基础饲粮中添加不同水平的包被酸化剂(CA)对肉仔鸡生长性能、消化道内环境及血清生化指标的影响。试验选用18日龄科宝500肉仔鸡960只,采用2×4交互设计,通过空气喷洒有害气体吸附剂改善鸡舍环境空气质量,将喷粉的鸡舍规定为良好环境,未喷粉的规定为较差环境,每个环境设4个组,分别为对照组、0.10%富马酸组、0.03%CA组和0.05%CA组,每组4个重复,每个重复30只鸡。肉仔鸡分别饲养在2个不同环境的鸡舍内,试验期25 d。结果表明:1)不同环境下,与对照组、0.10%富马酸组相比,0.03%CA组极显著增加了肉仔鸡平均日采食量(P<0.01),显著提高了盲肠乳酸杆菌数量(P<0.05);0.05%CA组盲肠双歧杆菌数量极显著高于其他各组(P<0.01),各组胃肠道pH差异不显著(P>0.05)。2)良好环境下,0.03%CA组肉仔鸡血清总蛋白含量极显著低于其他各组(P<0.01),0.05%CA组盲肠大肠杆菌数量显著低于0.10%富马酸组和0.03%CA组(P<0.05)。3)较差环境下,0.03%CA组盲肠大肠杆菌数量显著低于其他各组(P<0.05),0.05%CA组空肠乳酸杆菌数量显著高于其他各组(P<0.05)。4)对于平均日采食量、盲肠大肠杆菌和双歧杆菌数量、血清碱性磷酸酶和总超氧化物歧化酶活性,CA与环境的互作效应极显著 (P<0.01);对于盲肠乳酸杆菌和空肠乳酸杆菌数量,CA与环境的互作效应显著(P<0.05)。由此可见,添加CA能够改善肠道微生态环境,促进肉仔鸡生长;在良好环境下,CA的作用效果更好。

Abstract

This experiment was conducted to study the effects of dietary coated acidifier (CA) based on corn-soybean meal on growth performance, gastrointestinal environments and serum biochemical indices of broilers in different environments. A total of 960 18-day-old healthy Cobb 500 broilers were used in a 2?4 completely randomized design, and then air quality of chicken houses was improved by spraying harmful gas adsorbent. Chicken houses with spraying powder defined as a clean environment, and without spraying powder defined as a poor environment. The chicken were randomly assigned to four groups (control group, 0.10% fumaric acid group, 0.03%CA group, 0.05%CA group) in each environment with four replicates in each group and thirty broilers in each replicate. Broilers fed in two different chicken houses, and the trial lasted for 25 days. The results showed as follows: 1) in different environments, the average daily feed intake of 0.03%CA group were significantly higher than that of control group and 0.10% fumaric acid group (P<0.01), and the amount of cecal Lactobacillus of 0.03%CA group was significantly higher than that of control group and 0.10% fumaric acid group (P<0.05); the amount of cecal Bifidobaccteria of 0.05%CA group was significantly higher than that of other groups (P<0.01); there was no effect on gastrointestinal pH (P>0.05). 2) In the clean environment, the serum total protein content of 0.03%CA group was significantly lower than that of other groups (P<0.01), the amount of cecal Escherichia coli of 0.05%CA group was significantly lower than that of 0.10% fumaric acid group and 0.03%CA group (P<0.05). 3) In the poor environment, the amount of cecal Escherichia coli of 0.03%CA group was significantly lower than that of other groups (P<0.05), and the amount of jejunal Lactobacillus of 0.05%CA group was significantly higher than that of other groups (P<0.05). 4) The interaction of CA and environment had extremely significant effect on the average daily feed intake, the amount of cecal Escherichia coli and Bifidobacteria, activity of serum alkaline phosphatase and super oxide dismutase (P<0.01), and the interaction of CA and environment had significant effect on the amount of Lactobacillus in cecum and jejunum (P<0.05). In conclusion, dietary CA can improve the intestinal micro-ecological environment and growth performance of broilers. In addition, better effects can be found in the clean environment.
