The aim of the present study was to assess the effects of medium-chain fatty acid (MCFA) diet supplementation on growth performance, intestinal histomorphology, serum biochemistry and intestinal microflora of broiler chickens. The study was performed on 180 one-day-old broilers of the same origin (Cobb 500 hybrid), over a 42-day period. They were fed diets supplemented with three treatments: control group (basal diet without supplementation); group with MCFA supplementation; and group with MCFA and coccidiostat supplementation. Broiler chickens fed diets supplemented with MCFAs had a significantly greater final bodyweight. The weights of carcass cuts (breast, drumsticks with thighs and wings) were greater in broilers receiving MCFAs than in control broilers. The addition of MCFAs to broiler diet significantly increased villus length and crypt depth in the duodenum and caecum, and significantly decreased villus width in the duodenum and ileum. Additionally, serum HDL-cholesterol and triglyceride concentrations were increased significantly in broilers with MCFA dietary supplementation. The results indicated that the MCFA diet supplementation had a beneficial effect on the performance of broiler chickens, their intestinal histomorphology and microflora.
