Abstract

Assigned to 4 treatments, with 5 replicate, 20 birds per each replicate was conducted to determine the effect of diet supplementation with Lactobacillus cultures on some blood parameters and mortality of broiler chicken. Lactobacillus cultures used in this study prepared by sampling from broilers ileum (Ross 308) at 42 day of age. For this purpose the experiment carried out by feeding 4 levels of the Lactobacillus cultures (0%, 0.05%, 0.10% and 0.15%) were added to broiler basal diets. Hematological, biochemical tests were measured at day 21 and 42; hemoglobin, hematocrit, release of alanine transaminase, aspartate transaminase, lactate dehydrogenase, white blood cell, heterophils, lymphocytes, cholesterol and triglycerides. Mortality was recorded daily. The results of the recent experiment showed that, feeding diet with Lactobacillus cultures (0.15%) to chickens significantly (P<0.05) decreased hemoglobin, alanine transaminase and aspartate transaminase activity, cholesterol and triglycerides. Moreover, Lactobacillus cultures (0.15%) significantly (P<0.05) increased hematocrit and white blood cell at day 42 of age. Moreover, Lactobacillus cultures (0.15%) significantly reduced chicken mortality compared to the other group. There are no significant effects of Lactobacillus cultures on other blood parameters.
