Abstract

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.
