The Effect of Hydroalcoholic Extract of Allium Hirtifolium Compare to Flavophospholipol on Growth Performance, Some Blood Parameters, Microbial Population, and Intestinal Morphology in Broiler Chickens

This experiment was conducted to study the effect of hydroalcoholic extract of Allium Hirtifolium compare to for flavophospholipol antibiotic on growth performance, blood parameters, microbial population and intestinal morphology in broiler chickens (Ross 308). The experimental design was a completely randomized design with 5 treatments, 4 replications and 10 chickens in each replication (200 chicks). The experimental treatments were included: basal diet with no additives, and the basal diet supplemented with 500 mg/kg flavophospholipol or Allium hirtifolium extract at different levels (150, 300, 450 mg/kg). In the age of 25-42, using 450 mg/kg hydroalcoholic extract of Allium hirtifolium significantly improved body weight gain and feed conversion ratio compared to the control and antibiotic groups (p < 0.05). Blood parameters were not affected significantly by the dietary treatments. The colony count of lactobacillus bacteria in the ileum of chickens fed with 450 mg/kg of hydroalcoholic extract of Allium hirtifolium were significantly higher than antibiotic group (p < 0.05). The length of the villus in the birds fed with 450 mg/kg of hydroalcoholic extract of Allium hirtifolium was higher than the control group. In conclusion, using 450 mg/kg hydroalcoholic extract of Allium hirtifolium can improve performance parameters, count of benefit microbial bacteria, and intestinal morphology of broilers. In addition, hydroalcoholic extract of Allium hirtifolium (at 450 mg/kg) can be used as a good replacement for antibiotics.
