The effect of adding Chevillpowder (Ferulago angulate) on performance, blood parameters, intestine microflora and humeral immunity of female broiler chickens

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 Chevillpowder on microflora and immune response of femalebroiler 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 17chicks. Birds fed the same basal diets treatment with 0%(control)¡ 0.4 and 0.8%Chevillpowder in days 1 to 28¡ 29to 42and 1 to 42. For evaluating the immune system response in the days 28and 35¡ we injected sheep’s red blood cells (SRBC) 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 Chevill. Lactobacilluscount significantly increased in 0.4%or 0.8%Chevilltreatments¡ but E. coliwas decreased significantly on day 28of age (p
