AbstractThis experiment was conducted in Therthar poultry fields of the animal's product Theraar company. The effect of adding local probiotic and the imported Biotronuc SE to the feed was studied with different levels of barley on productive traits of laying hens at 21 weeks upto 40 weeks of age. Two hundred and fourty three laying hens at 21 weeks of age distributed on 9 treatments with three replicates for each treatment. The local probiotic was used at a level of 5 kg / ton fed with 3 levels of barley 12, 22 and 32 % of diet. The Biotronic SE was used at a level of 2 kg / ton fed with the presence of 3 levels of barley 12, 22 and 32 of the diet and 3 levels of barley 12 , 22 and 32% of the diet without any additive. Using 5 kg/ ton local probiotic and 2 kg / ton Biotronic SE in this experiment according to the manufacturing company of these products. The results of this experiment showed significant reduction (P < 0.01) in egg production rate , accumulative egg per hen, feed conversion coefficient, feed intake, egg mass and accumulative egg weight with increasing the level of barley in the die. whereas, treatments of adding Biotronic SE and local probiotic with different levels of barley were improved significantly (P < 0.01) as compared with treatments contained the same levels of barley without any additives in productive traits of laying hens. Morever, Biotronic SE treatments were significantly improved over local probiotic treatments with these levels of barley 22 and 32% of the diet in productive traits of laying hens. Morever, local probiotic treatments were significantly improved over Biotronic SE treatments with the level of 12% barley of the diat.
