Abstract: 

This experiment was conducted to evaluate the effects of using of probiotic, organic acid and blends of some medicinal herbs on performance, egg quality, blood biochemical and immunity parameters of laying hens. The experiment was carried out in a completely randomized design with one hundred and ninety two of Hy-Line (W36) laying hens from 37 to 49 weeks of age. There were randomly assigned to 4 dietary treatments with 4 replicates and 12 hens in each replicate. The treatments included: 1) control group 2) using 0.005 % of probiotic (Protexin®), 3) using 0.2% of propionic acid and treatment 4) using blends of medicinal herbs (zizaphora, Menta pulagum, peppermint and nettle. The results showed that there were some significant difference in performance and egg quality between experimental groups (p>0.05). The highest amount of egg mass production (51.38g), and the best value of feed conversion (2.04)), were observed in experiment group 3. Whereas the best yolk color index (4.5) was observed in experiment group 4.
There were not observed any significantly difference between experimental groups in blood biochemical and immunity parameters. With consideration in obtained results in laying hens using probiotic, organic acid and blends of some medicinal herbs have positive effects on performance and egg yolk color.
