The addition effect of Ginger and Antibiotic to broiler diet on intestinal microbiota and villi length and crypts depth

Abstract

Abstract AbstractThe present experiment aimed to study the effect of diet supplementation ginger and antibiotic on intestinal microbiota and villi length and crypts depth، Three hundred fifty two unsexed day old (Hubbard) broiler chicks and divided to eight treatment with two replicates (22 chicks per replicate) as follows: First treatment: Control treatment with two replicate of 44 chicks for one week. Second treatment : 0.4% ginger treatment with two replicate 44 chicks for one week. Third treatment : 0.4%ginger treatment with two replicate 44 chicks for seven week. Fourth treatment : 0.8 % ginger treatment with two replicate 44 chicks for one week. Fifth treatment : 0.8% ginger treatment with two replicate 44 chicks for seven week. Sixth treatment : 0.5gm antibiotic / kg feed with two replicate 44 chicks for one week. Seventh treatment : 0.5gm antibiotic / kg feed with two replicate 44 chicks for seven week and then supplemented with 0.4% ginger from 8-49 days. Eighth treatment : 0.5gm antibiotic / kg feed with two replicate 44 chicks for seven week and then supplemented with 0.8% ginger from 8-49 days. The results was showed non significant differences in the number of total aerobic bacteria at 1st week but there are lower significant (P≤0.01) in total aerobic and coliform bacteria for ginger treatment 0.08% contrast with other treatment at 3rd and 7th week respectively . with regard to jejunum tissue، the ginger treatments were high significant compared with other treatment in villi length ، crypts depth and villi length to crypts depth ratio
