Effect of selected probiotics and synbiotics on growth performance and blood-biochemical changes in broiler chickens

In broiler production, probiotics and synbiotics have been introduced as a replacement for antibiotic growth promoter. The study investigated the effects of selected probiotics and synbiotics on body weight and blood-biochemical parameters in broiler chickens. A total of 48, day-old Lohman broiler chicks were reared for 28 days. At day 13, the chicks were randomly divided into four equal groups: A, B, C, and D (n=12 in each group). The group A was considered as non-treated control. Group B was supplemented antibiotic (ciprofloxacin) with water. Group C and D were supplied with probiotics at a dose rate of 1 g/L and synbiotic 1.2 g/L, respectively through drinking water. Synbiotic treated broilers had significantly (p [J Bangladesh Agril Univ 2021; 19(4.000): 471-476]
