摘　　要：旨在研究枯草芽孢杆菌与地顶孢霉复合制剂对蛋鸡生产性能、蛋品质及相关肠道指标的影响。试验选用30周龄的海兰蛋鸡240只,随机分为复合添加剂试验组和对照组,每组4个重复,每个重复30只鸡。对照组饲喂基础饲粮,试验组在基础饲粮中添加浓度为5×10^(8) CFU枯草芽孢杆菌和地顶孢霉的复合制剂。试验预试期1周,试验期12周,每天记录生产数据,在试验的第1、7和13周收取蛋样测定蛋品质,并在1周龄与13周龄进行抽样屠宰,取盲肠内容物分析盲肠菌群。结果显示:与对照组相比,复合制剂极显著提高了蛋鸡的产蛋率(P<0.001),但对破蛋数无显著影响(P>0.05);枯草芽孢杆菌与地顶孢霉复合制剂对蛋型指数、蛋重、哈夫单位和蛋壳厚度均无显著影响(P>0.05),但极显著提高了第1周的蛋黄重(P<0.01),显著提高了第7周的蛋白高度(P<0.05)和蛋黄颜色(P<0.05)。此外,与对照组相比,试验组第13周的蛋壳强度也有了极显著提高(P<0.01);枯草芽孢杆菌与地顶孢霉复合制剂对蛋鸡盲肠沙门氏菌和乳酸杆菌的数量无显著影响(P>0.05),但极显著降低了大肠杆菌的数量(P<0.01)。结果表明,产蛋鸡饲粮中添加枯草芽孢杆菌和地顶孢霉复合制剂能够提高蛋鸡生产性能、蛋品质并降低肠道中大肠杆菌的数量,改善肠道菌群结构。The purpose of this study was to investigate the effects of Bacillus subtilis and Acremonium spp compound preparation on the production performance, egg quality and related intestinal indexes of laying hens. 240 30-week-old Hyline layers were selected and randomly divided into the compound additive experimental group and the control group, with 4 replicates in each group and 30 chickens in each replicate.The control group was fed with a basic diet, and the experimental group was fed with a combination diet of Bacillus subtilis and Acremonium spp. with a concentration of 5×10^(8) CFU/g. During the trial period of 13 weeks preceded with one week of preliminary experiment, the production data of the birds were recorded every day. Egg samples were collected at the first, 7;and 13;weeks of the trial to determine their quality, and Sample hens at the first and 13 th weeks of age were taken and slaughtered to obtain intestinal tissue and cecal chyme samples for analysis oftheir intestinal morphology and microbial abundance.The results indicated that compared with the control group, the compound preparation group significantly increased their laying rate(P<0.01), but presented no significant effect on the number of broken eggs(P>0.05). The compound preparation ofBacillus subtilisandTerpirosishad no significant effect on the egg type index, egg weight, huff unit and eggshell thickness(P>0.05), but significantly increased their yolk weight at the first week(P<0.01), and significantly increased protein height(P<0.05) and yolk color(P<0.05) at 7 thweek. In addition, there was a significant increase in eggshell strength of the compound preparation group at 13 thweek, compared withthat of the control group(P<0.01). The combination ofBacillus subtilisandP. terricolahad no significant effect on the number ofSalmonella typhimuriumandlactobacillusin the cecum of the laying hens(P>0.05), but significantly reduced the number ofE. coli(P<0.01). The results of this study indicated that supplementingBacillus subtilisandAcremoniumspp.
