Effect of dietary prebiotic and acidifier supplementation on the growth performance, carcass characteristics and serum biochemical parameters of broilers

This study investigated the effect of dietary supplementation with the fermacto prebiotic and Biotronic®S.E (an acidifier) on the growth performance, carcass characteristics and serum biochemical parameters of broiler chickens. 240 day old Ross 308 broilers were equally distributed into 24 floor pens and reared for 42 days. A basal diet was formulated according to the recommendations of NRC for starter (1 to 21 days) and grower (22 to 42 days) periods and considered as control diet. Four tested diets were formulated as listed control diet (without any additives), fermacto prebiotic, Biotronic®S.E (an acidifier) and mixture of fermacto prebiotic plus Biotronic® S.E. Six replicate were used for each treatment. The results of this study indicate that addition of fermacto prebiotic and Biotronic® S.E increased the final body weight, significantly (p˂0.05). Furthermore, addition of additives decreased abdominal fat, triglycerides, serum cholesterol and increased carcass weight. Addition of fermacto prebiotic plus Biotronic® S.E had the best performance, carcass characteristics and lowest serum cholesterol on broiler chickens at 42 day of age.   Key words: Fermacto prebiotic, Biotronic® S.E, performance, broiler, carcass characteristics, serum cholesterol.
