Effects of different levels of dinamion prebiotic and Biotronic organic acid on immune response and blood parameters in laying hens

Different levels of Dinamion® prebiotic and Biotronic® organic acid added to standard diet, to determine its effect on blood parameters and immune response compared to control group. A total of 130 52 weeks of age lyaing hens (nick chick) were divided into 9 treatments with 5 replications of 3 birds per each, and randomly assigned to 27 pens, in a complete randomized design (CRD) with a factorial arrangement (3×3). Experimental treatments included dinamion prebiotic and biotronic organic acid in three levels (Zero, recommended level and double level of recommended). Data were analyzed by using general linear model (GLM) procedure of the SAS version 9.1 program for repeatedly measured data. The results showed that Dinamion prebiotic had not significant effect on lipid profile and blood factors such as total protein, uric acid, globulin, albumin and glucose (P>0.05). Using of organic acid significantly decreased cholesterol, LDL, total protein and uric acid concentration and on the contrary significantly increased serum glucose concentration (P0.05). In conclusion, supplementation laying hens with dinamion prebiotic and biotronic organic acid cause improvement of feed intake, laying egg percent.
