Effects of sodium butyrate on the production performance and the morphological of small intestine in black-bone chickens
Abstract: Objectives: The study aimed to study the effects of sodium butyrate on the production performance and the morphological of small intestine in black-bone chickens. Methods: Choose 512 black-bone chickens of 21 weeks old were randomly pided into control group and experimental group. The control group was fed the basal diet without additives, and the experimental group was fed with basal diet supplemented with 0.05% sodium butyrate. Record the product data every day. Slaughter at 36 weeks of age, and the small intestinal samples were collected. Then select 3 black-bone chickens of control group and 3 black-bone chickens of experimental groups to make paraffin sections, for HE staining. Results: Microscope observation showed that the duodenum, jejunum and ileum of villus height were increased and the crypt depth were reduced. Statistical analysis of relevant data can be drawn that the experimental group compared with control group, villus height and v/c of the duodenum, jejunum and ileum were significantly increased (P < 0.05), crypt depth were reduced (P < 0.05). Conclusions: The results showed that adding 0.05% sodium butyrate in black-bone chickens diet, can improve small intestinal morphology, increase the villus height, reduce the crypt depth, and increase v/c of duodenum, jejunum and ileum. It’s explain that sodium butyrate can effectively regulate the intestinal health of black-bone chickens, improve the intestinal absorption efficiency of nutrients, and promote the growth and improve the production performance.
