本工作的目的是研究一种新型多菌种益生菌在肉鸡营养中的效果。该益生菌含有2株乳杆菌、1株双歧杆菌、1株肠球菌和1株小球菌属。将400只1日龄Cobb肉鸡公鸡分成4个试验组，每组6周。试验组饲喂玉米-大豆基础日粮，分别为：“对照组”，不添加其他添加剂；“饲料和水中添加益生菌”(PFW)，在整个试验期间按规定的间隔在饲料和水中添加益生菌；“饲料中添加益生菌”，饲料中添加益生菌(PF)，与PFW中一样；以及“抗生素”，在饲料中添加阿维拉霉素2.5 mg/kg。盐霉素钠被用作球虫药。每个处理有5个重复，共20只肉鸡。测定了处理对肉鸡生产性能和盲肠微生物生态参数的影响。每周和总体测定肉鸡体重、采食量和饲料转化率。实验结束后，测定盲肠微生物区系组成、挥发性脂肪酸浓度和5种细菌糖酵解酶(α-半乳糖苷酶、ss-半乳糖苷酶、α-葡萄糖苷酶、ss-葡萄糖苷酸酶)的活性。总体而言，处理PFW显示出与AB没有区别的促进生长的效果。总体而言，AB组的饲料转化率显著优于对照组(P
The aim of this work was to investigate the efficacy of a new multibacterial species probiotic in broiler nutrition. The probiotic contained 2 Lactobacillus strains, 1 Bifidobacterium strain, 1 Enterococcus strain, and I Pediococcus strain. Four hundred 1-d-old male Cobb broilers were allocated in 4 experimental treatments for 6 wk. The experimental treatments received a corn-soybean basal diet and were as follows: "control," with no other additions; "probiotic in feed and water," (PFW) with probiotic administered at I g/kg of feed for the whole period and in water on scheduled intervals during the first 4 wk; "probiotic in feed," (PF) with probiotic in feed as in PFW; and "antibiotic," (AB) with addition of avilamycin at 2.5 mg/kg of feed. Salinomycin Na was used as a coccidiostat. Each treatment had 5 replicates of 20 broilers. Treatment effects on parameters of broiler performance and cecal microbial ecology were determined. Broiler BW, feed intake, and feed conversion ratio were determined on a weekly and overall basis. Cecal microflora composition, concentration of volatile fatty acids, and activities of 5 bacterial glycolytic enzymes (a-galactosidase, ss-galactosidase, a-glucosidase, alpha-glucosidase, and ss-glucuronidase) were determined at the end of the experiment. Overall, treatment PFW displayed a growth-promoting effect that did not differ from AB. Overall, feed conversion ratio in treatment AB was significantly better (P
