Abstract: This study was aimed toproduce compound preparations of Fuzhengjiedusan fermented with Lactic acid bacteria and analyze its effectson growth performancesand immune organ growth of broilers. Firstly, to identify the influence of traditional Chinese medicine on the growth of Lactic acid bacteria, the medium for the growth of Lactic acid bacteria was filled with different proportions of Astragalusmembranaceus, Radix Isatidis, Epimedium and compound Chinese herbal medicine extracts by single factor test. Secondly, to confirm the optimum medium, orthogonal test was used to optimize the culture medium of compound medicine liquid. Finally, 450 one-day-old healthy AA broilers were randomized into three groups, each group had 3 repeats: control group (antibiotics), group Ⅰ(fermented preparation), group Ⅱ (unfermented preparation). The growth and immune organ index were determined in 21 and 42 days after administration. The results showed that the highest viable count of Astragalusmembranaceus, Radix Isatidis, Epimedium and compound medicine liquid groups were increased by 261.64%, 505.48%, 156.16% and 564.38%, respectively, compared with control group. The optimum medium composition was compound medicine liquid 100 mL, brown sugar 2.0 g, peptone 0.3 g, soybean meal 2.0 g. The viable count of fermentation liquid was 7.13×109 CFU/mL.The production results showed that in period of 1~42 days, the daily weight gain of group Ⅰ and Ⅱ were separately increased by 17.84% and 8.22% (P<0.05) than that of the control. What's more, the feed conversion rate was reduced by 10.88% (P<0.05). The average daily feed intake was significantly higher than control group (P<0.05). At 21 and 42 days, the spleen index of group Ⅰ were improved by 11.04% and 13.58% (P<0.05), respectively. The bursal index were raised by 31.30% and 26.23% (P<0.05), respectively. However, the spleen index of group Ⅱ were improved by 7.79% and 7.41% (P<0.05), respectively. The bursal index were raised by 15.65% and 11.48% (P<0.05), respectively. On the basis of the above results, it could be suggested that Chinese herbal medicine extracts can promote lactic acid bacteria proliferation and compound fermentation liquid can improve growth performance in broilers, as well as immune organ development.
