Effects of Pueraria lobata leaf powder as a feed additive on the immune system and growth performance of broiler chickens

The present research assessed the effect of different levels Pueraria lobate leaf (PLL) on growth performance, immunity, antioxidant capacity, and blood index in broiler feed. A total 384 at 21 days old chicks were assigned to 1 4 dietary treatments examine benefits basal diet, diet +1% PLL, +2% PLL +3% PLL. trial was divided into 2 time periods, including starter from 21-49 finisher 50-70. addition 2% 3% powder diets increased protein content, triglycerides, albumin, low-density lipoprotein (p < 0.05). In contrast, cholesterol, aspartate aminotransferase, urea nitrogen, high-density serum reduced antioxidants, superoxide dismutase, IgM, IgG, other aspect, significantly increased, nevertheless, content malondialdehyde interleukin decreased. Although supplementation with did not have an slaughter clear improvements thymus organ index, immune functions 0.05) observed. P. is a strong candidate as potential feed additive due its wide range sources well-established record safety, efficacy improving protein, lipoprotein, Ig M G without any adverse effects performance. conclusion, can be regarded novel resource for replace antibiotics.
