| Abstract | ||
| This experiment was conducted in therthar poultry fields. The effect of adding local probiotic to the feed was studied with different levels of barley on productive traits of laying chicks at one day old upto 20 weeks of age. Four hundred and five chicks were used in an experiment included 9 treatments, with three replicates for each treatment. The local probiotic was used at three levels 0, 3 and 5 kg/ ton feed with three levels of barley 12, 22 and 32% of the diet. The results of this experiment showed significant reduction (P<0.01) in feed conversion coefficient at 3, 17 and 20 weeks of age and average body weight at 3 weeks of age and significant increase (P<0.01) in feed intake with increasing the level of barley in the diet. The resultsof this experiment showed significant improvement (P<0.01) treatments with added local probiotic in feed conversion coefficient and average body weight 3, 17 and 20 weeks of age and significant reduction (P<0.01) in feed intake at 10, 17 and 20 weeks of age, as compared with treatment without any additive. whereas, treatment of adding local probiotic with defferent levels of barley showed significant reduction (P<0.01) in feed intake at levels of barley 12, 22% of the diet. The results of this experiment showed significant improvement (P<0.01) in feed conversion coefficient and significant increasing. (P<0.01) in average body weight at 3, 17 and 20 weeks of age for treatments of local probiotic with different levelsof barley of the diet . | ||
