Abstract
The present study aimed to evaluate the statement effect of in ovo injection with probiotics bacteria at seventh days of incubation on subsequence productive performance of broiler chicks Ross308 with determining the best type of probiotic bacteria vital injected used in this study. The experiments were carried out in the hatchery and poultry farms of agriculture college-University of Al-Muthanna, while the chicks were reared during the period of Nov. 5th, 2011 until Des. 31st, 2011. The treatment groups as follow: First group (T1) (Negative control): without injection. Second group, (T2) (positive control): eggs Injected sterilized distilled water, Third treatment (T3): eggs injected with Lactobacillus acidophilus by 107 bacteria/egg, Fourth treatment(T4):eggs injected with Bacillus subtilus by 107 bacteria/egg, Fifth treatment (T5): eggs injected with Bifidobacterium by 107 bacteria/ egg and Sixth treatment(T6): eggs injected with mixture of probiotics above by 108 bacteria/egg. A total of 360 unsexed day old chicks hatched from six treatments were reared in the batteries (four floors for each treatment), each floor had a cage dimensions 1.5×1 meters, chicks were randomly distributed to treatment )60 chicks/treatment(, three replicates for treatment (20 chicks per replicate). Results showed that injection eggs with probiotics improved a highly significant (P≤0.01) in productive performance, average body weight, weight gain, feed intake, food conversion efficiency and production index, with a significant reduction (P≤0.05) in the mortality of broilers.
