Evaluation of performance, hematology, blood metabolite and histomorphometry of gasterointestinal tract of broiler chickens treated with dietary alginate and antibiotics

Dietary additives especially prebiotics can improve performance and immunity of broiler by increasing health status. This study was performed to investigate effect of dietary alginate and antibiotic on performance, carcass traits, Hematology and histology of intestinal tract in male broilers. A total of 144, day-old male broilers (Ross 308) were randomly assigned to three treatments with four replicates. This experiment was conducted in a completely randomized design. The experimental treatments consists 1) basal diet as control group 2) basal diet + 200 ppm Alginate 3) basal diet + 200 ppm antibiotic (felavophospholipol). Body weight gain at 1-10, 10-24 and 24-42d was not significantly differ between treatment but only Body weight gain at 1-42 was significant between control and other treatments significantly. FCR in all periods had significantly differed in Alginate group with control. There are no significantly differences in hematological and white blood cell differentiation count traits. There are no significantly differences in carcass traits, gizzard, abdominal fat, and thymus and spleen relative weight in all experimental treatments. Serum cholesterol, HDL, LDL, VLDL did not show any significant differences among treatments. Serum glucose, triglyceride was significantly different and all treatment and alginate had lower than control group. Deudenum and jjenum height of villi, Villus height to crypt depth ratio in deudenum and jejenum had significantly difference in alginate group and control group. Based on our results, it can be concluded that 200 ppm alginate group had simmilar performance parameters in compared to control group and it had better histometric parameters so alginate can use efficiency as prebiotic source to increasing performance in male broiler.
