The Effect of Ferulaassa-Foetida Gum Powder Compare to Antibiotic on Performance, Microbial Population and Intestinal Morphology in Broiler Chickens

This experiment was conducted to investigate the effect of different levels of Ferulaassa-foetida gum powder and antibiotic on performance, intestine morphology and microbial population in broiler chicks. The experiment was carried out in a completely randomized design with 240 chicks in 5 treatments, 4 replicates and 12 chicks per replicate. Treatments included: 1) basal diet without additives, 2) basal diet containing 100 mg per kg of antibiotics Avilamycin.3, 4 and 5) basal diet contain 0.1, 0.2 and 0.3 Ferula assa-foetida gum powder, respectively. The results showed that in whole experiment period, treatment fed antibiotic had the highest body weight (P
