The present study was conducted to evaluate the effects of feeding garlic along with multi-strain probiotics on performance of broilers. One hundred eighty no. (N=180) of day old commercial Ven Cobb 50 broiler chicks 45 chicks in each group with 3 replicates of 15 chicks each by following Randomized Block Design (RBD) and chicks were randomly distributed into 4 treatment groups i.e. T₀, T₁, T₂ and T₃ on the basis of their body weight. Experimental diets were formulated for starter and finisher phases to meet the nutrient requirement as per ICAR (2013) using commonly available ingredient. A corn and soybean meal based diet was used as the control diet (T₀). The experimental diets were formulated by mixing the basal diet with garlic powder (GP) and multi-strain probiotics (MSP) at 0.25, 0.50 or 0.75% (GP+MSP) in diets of groups T₁, T₂ and T₃, respectively. daily weight gain and feed conversion ratio (FCR) was significantly (Pd 0.05) improved in T₂ group as compared to other group. Jejunal villus height and villus width was significantly (P<0.05) higher in T₂ group. The population of cecal microflora was not altered by dietary treatments. Broiler chickens fed the 0.50% (MSP+GP) diet exhibited (P<0.05) lower levels of serum triglycerides and cholesterol compared to control group. Collectively, the results show that dietary supplementation of GP+MSP at 0.50% can be used as a synbiotic for better production and health status in commercial broilers birds.
