研究了不同剂量植物乳杆菌RS5、RI11、RG14和RG11菌株(Com3456)复合代谢产物对肉鸡生产性能的影响。将504只罗斯肉鸡随机分为7个处理组，分别饲喂标准玉米-大豆基础日粮(阴性对照)、玉米-大豆基础日粮+100ppm新霉素和土霉素(阳性对照)、标准玉米-大豆基础日粮+0.1%植物乳杆菌RS5、RI11、RG14和RG11菌株代谢物组合(COM3456)、标准玉米-大豆基础日粮+0.2%COM3456；(V)标准玉米-豆基日粮+0.3%的Com3456(Vi)标准玉米-豆基日粮+0.4%的Com3456和(Vii)标准玉米-豆基日粮+0.5%的Com3456。添加不同剂量的Com3456可改善仔猪的生长性能，减少肠杆菌科细菌的数量，增加乳酸菌的数量，增加小肠绒毛高度和粪便挥发性脂肪酸浓度。0.4%和0.2%的康美3456处理效果最好，尤其是在生长性能、饲料转化率和绒毛高度等方面。然而，建议的剂量为0.2%，因为其浓度较低，产生的效果与0.4%的补充剂相似。这些结果表明，肉鸡日粮中添加0.2%是取代抗生素生长促进剂的最适水平。
The effects of feeding different dosages of metabolite combination of L. plantarum RS5, RI11, RG14 and RG11 strains (Com3456) on the performance of broiler chickens was studied. A total of 504 male Ross broilers were grouped into 7 treatments and offered different diets: (i) standard corn-soybean based diet (negative control); (ii) standard corn-soybean based diet +100 ppm neomycin and oxytetracycline (positive control); (iii) standard corn-soybean based diet + 0.1% metabolite combination of L. plantarum RS5, RI11, RG14 and RG11 strains (Com3456); (iv) standard corn-soybean based diet + 0.2% of Com3456; (v) standard corn-soybean based diet + 0.3% of Com3456 (vi) standard corn-soybean based diet + 0.4% of Com3456 and (vii) standard corn-soybean based diet + 0.5% of Com3456. Supplementation of Com3456 with different dosages improved growth performance, reduced Enterobacteriaceae and increased lactic acid bacteria count, and increased villi height of small intestine and fecal volatile fatty acid concentration. Treatment with 0.4% and 0.2% Com3456 had the best results, especially in terms of growth performance, feed conversion ratio and villi height among other dosages. However, the dosage of 0.2% was recommended due to its lower concentration yielding a similar effect as 0.4% supplementation. These results indicate that 0.2% is an optimum level to be included in the diets of broiler in order to replace antibiotic growth promoters.
