Effect of Synbiotic Supplementation on The Growth and Hematological Attributes of Broiler Chicken (Gallus Gallus) Infected with Coccidiosis

This study was conducted to examine the effects of synbiotics against coccidiosis infected broilers based on growth performance, and selected hematological attributes (RBCs, WBCs, hemoglobin, ALT, AST, uric acid, triglyceride, and glucose). The main objectives of this study were to evaluation the negative impacts of coccidiosis, and amelioration of its harmful effects by using synbiotic (diclacox 1ml/5l and protexin 1mg/5l of water in a ratio of 1:1). The whole experiment was conducted in an environmentally control shed. A total number of 120-day old broiler chickens were selected, and on 21st day were equally divided into four groups with each group having 3 replicates (n=10). The details of the grouping are T0 (negative control), T1 (Positive control), T2 (supplemented with synbiotic, and basal diet while T3 treated with basal diet, synbiotic, and infection (3.0 ×104 oocytes). Results revealed that supplementation of synbiotic significantly improved broilers' growth performance, and hematological attributes during 5th, 10th, and 15th days of samplings. The T1 group exhibited significant decrease in growth, and selected hematological parameters however, after treating with synbiotic the negative effects of coccidiosis were significantly decreased. Moreover, T3 showed positive improvements in all parameters under study. Maximum growth of organs on 15th days of sampling was found higher in infected group of birds as in spleen (109.09%), kidney (15.79%), gizzard (21.60%) and liver (44.09%) at (P ≤ 0.05). Furthermore, no lesions and oocyte shedding were observed in T0 but the aforementioned parameters were found higher in T1. It was concluded that supplementation of synbiotic improved production performance of broilers and selected blood indices of broilers infected with coccidiosis.
