Effect of Chinese Propolis Supplementation on Ross Broiler Chicks: Microbial Population in Fecal matter and Litter
Keywords:Propolis; Bacterial count; Gut microflora; Litter; Broiler.
Propolis has been considered a good candidate for health amelioration and disease prevention over a long period of time. Effect of feed supplementation with Chinese ether extract propolis was evaluated for the antibacterial action on (Ross 308) broiler chicks and their litter over 35 days. The addition of different levels of propolis (100, 250 and 750 mg/kg diet) on total aerobic and coliform bacteria as well as Lactobacillus spp. and bifidobacteria were determined. Supplementation of propolis significantly increased (p<0.05) the desired stimulating effect of Lactobacillus spp. and Bifidobacteria in fecal samples of all treatment groups compared to control group. However, propolis did not have an impact to reduce the total aerobic and coliform bacteria compared to control group in both fecal and litter samples. In conclusion, Chinese propolis improved the beneficial normal gut microflora and had a limited effect on the total aerobic and coliform bacteria in broiler chicks and litter quality.
