Abstract
Restriction of using antibiotics in human and animal brought an increasing application of effective biological compounds in this regards. In present research, to investigate the effects of Cavill powder on microflora and immune response of female broiler chicken, a total of 476 commercial broilers (Cobb strain) randomly assigned to 7 treatments, each with four replicates in a way that each replication contained 17 chicks per each. Birds fed the same basal diets treatment with 0% (control), 0. 4 and 0. 8% Cavill powder in days 1 to 28, 29 to 42 and 1 to 42. For evaluating the immune system response in the days 28 and 35, we injected sheep’s red blood cells into wing vein of two birds at each replicate. To measure the carcass weight, fat weight, triglycerides, cholesterol, HDL and VLDL, two birds were killed in each replication. The highest average of daily gain observed in the control group and the lowest one was seen in 0. 8 percent Cavill. Lactobacillus count significantly increased in 0. 4% or 0. 8% Cavill treatments, but E. coli was decreased significantly on day 28 of age (p
