Histomorphometry of the Duodenum of Ducks (Anas platyrhyncos) after Administration of Nanochitosan in Feed

Poultry farming business has several problems such as lack of availability on raw materials, expensive feed prices, and egg production that is not optimal. To overcome the problem high prices duck productivity, we need to add additives nanochitosan. This study aimed analyze effect nanochithosan digestive function intestine tenue (duodenum) indicated by histomorphometric changes in duodenum Tegal ducks (Anas platyrhyncos). Duodenal histomorphometry related was measured, including lumen diameter, villi height, epithelial cell thickness, muscular layer thickness. used a completely randomized design consisting 5 treatments with replications. The research included P0 control (basic without nanochitosan particle additives) P1, P2, P3, P4 addition nanochitosanwith doses 2.5; 5; 7.5; 10 grams/kg respectively). variables observed were duodenal muscle data analyzed using analysis variance (ANOVA) 95% confidence level. results showed particles had significant diameter thickness (P0.05). ducks. conclusion this concentration 2.5-10% can improve an increase thickening, layer. novelty from additive repair From research, people gets benefit knowing use digestion performance productivity
