Effect of a mixture of monoglycerides with salinomycin on the growth performance and intestine morphology in broiler chickens

This study aims to interact with the combined influence of monoglyceride supplementation and salinomycin on growth performance and the morphology of the small intestine in broiler chickens. A factorial treatment design was employed in a completely randomized design (CRD). The broiler chickens were randomly divided into four experimental groups, the treatments studied were as follows: 1) Control group (without monoglyceride and salinomycin supplementation), 2) 0.05% monoglyceride supplementation combined without salinomycin, 3) 0.006% salinomycin without monoglyceride supplementation, and 4) 0.05% monoglyceride supplementation combined with 0.006% salinomycin. The study results indicated that the combined supplementation of monoglycerides and salinomycin had an interaction effect on the feed conversion ratio during the first 10 days, villus height: VH in the duodenum, and crypt depth: CD with villus height/crypt depth ratio: CD in the jejunum, which were significantly different statistically. Therefore, the supplementation of 0.05% monoglycerides combined with 0.006% salinomycin has an interaction effect on the feed conversion rate to body weight (days 1-10), the increase in VH in the duodenum, and the CD, along with the VH: CD ratio in the jejunum, resulting in improved growth performance and morphology of the proximal small intestine in broiler chickens.
