Effect of uropgialectomy and diet supplementation with probiotics on fertility, hatchability and digestive gut microflora of Japanese quail birds

Abstract

This experiment was carried out at the Poultry station / state board for Agricultre research Abo-Grabe ,lasted for 28 weeks ,to determind the effect of uropygialectomy locally and imported probiotics supplementation on fertility and hatchbility of Japanes quails and to count the number of Lactobacilli and coliform Bacteria in the digestive tract of Japanes quail birds.Atotal of 540 quails (180 male and 360 female) were randomly distributed into 6 treatment groups with 3 replicates for each and experiment groups were as follow: T1: control group , T2 : uropygialectomy + control diet , T3 : uropygialectomy + locally prepared probiotic in diet 5 gm /kg , T4 : locally prepared probiotic in diet 5 gm /kg , T5 : uropygialectomy and imported probiotic (Biomin) in diet 2gm /kg , T6: imported probiotic (Biomin) in diet 2gm /kg. The results were showed that uropygialectomy and probiotics supplementation had got highly significant effect (P<0.01) in fertility and hatchability compared with control group at 16 and 24 weeks of ege. The control group had the heist percent of emberuo mortality while there were no significant difference between (T1 and T2) in pipet chicks. There were no significant differences in chicks weight between treatments in 16 weeks of age while treatments (T2 , T3 , T5) had a significant superiority compared with (T1 , T4 , T6) in chicks weight at 24 weeks of age. Fed supplemented with locally and imported probiotics showed a significant effect (P<0.05) in rasing number of lactobacilli in the digestive tract and reduced the number of coliform bacteria while there were no significant effect of uropygialectomy on the number of microflora in the digestive tract Japanes quail birds.
