Abstract

An experiment was conducted to investigate the effects of supplementary herbal products [Miracle20^ⓡ(M20)] on the performance, nutrient digestibility, small intestinal microflora and serum IgG level in broiler chickens. One thousand one-day-old broiler chickens(Ross^ⓡ) were assigned to five treatments: control(T1), 50ppm chlorotetracycline(CTC; T2), 0.2% M20-S(T3), 0.2% M20-D(M20-S fortified in Angelica gigas, Dioscorea japonica and Schizandra chinensis; T4), 0.2% M20-A(M20-S minus Schizandra chinensis and plus Plellidendron amurense; T5). Each treatment had four replications (two for each sex) of 50 birds. Growth performance was not significantly affected by dietary treatments. The herbal products supplementation tended to improve the weight gain of male broiler chicks, but showed no significant difference. Nutrient digestibilities and ammonia gas level on the litter were not significantly affected by treatments. The colony forming unit(CFU) of CI. perfringens in small intestine was significantly lower in treatments T2 and T5 at 26 days of age while the CFU of E. coli was significantly lower in T3 compared to T1 at 42 days of age(P$lt;0.05). The level of serum IgG tended to increase with dietary herbal products supplementation.
These results indicate that dietary herbal products(M20) do not significantly affect growth performance and nutrient digestibilities in broiler chickens but have positive effects on small intestinal microflora and serum IgG level.
