ABSTRACT Recently the use of antibiotic growth promoter (AGPs) in poultry feed is banned in China, leading to the increasing demand for AGPs substitutes. Probiotics have been considered as a potential substitute. The purpose of this study was to evaluate the effects of probiotic on serum biochemistry, and growth promotion of body weight and visceral organs and in Lohmann Brown chicks aged 0 to 9 weeks. Five hundred and forty 1-day-old male chicks were randomly divided into three groups, with six replicates and 30 chicks in each replicate. The experiment was carried out over 70 days. Dietary treatments were: (1) basal diet alone (control group); (2) basal diet containing 0.1% probiotics (probiotic group); and (3) basal diet containing 0.01% zinc bacitracin in the feed (antibiotic group). The body weight (BW) of probiotic group was significantly higher than that of the control group during the whole trial period (p<0.05). ADG (0~70 d) in the probiotic group and the antibiotic group was higher than that in the control group (p<0.05). The Oliver weight and serum total protein (TP) in the probiotic group was higher than that in the control group on the 63rd day (p<0.05). The length of the duodenum, the weight of the spleen, duodenum and Jejunum in both the probiotic and antibiotic groups were higher than those in the control group (p<0.05). The ileum weight in the probiotic group was significantly higher than those in the control group (p<0.05). The ileum length in the probiotic group was significantly longer than that in both the antibiotic and control groups (p<0.05). Probiotic mix with Bacillus subtilis and Pediococcus acidilactici play a similar role in promoting growth of body and visceral organs, and it is a promising growth promoter for Lohmann Brown chicks (0 to 9 weeks).
