Effect of Dietary Supplementation of Organic Acids on Performance, Intestinal Histomorphology, and Serum Biochemistry of Broiler Chicken

Abstract

The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, intestinal histomorphology, and blood biochemistry of broiler chicken. The birds in the control (T1) group were fed the basal diet whereas in other treatment groups basal diet was supplemented with 2% butyric acid (T2), 3% butyric acid (T4), 2% fumaric acid (T4), 3% fumaric acid (T5), 2% lactic acid (T6), and 3% lactic acid (T7). Broiler chicken fed diets supplemented with organic acids had significantly (𝑃<.05) improved body weight gains and feed conversion ratio. No effect (𝑃<.05) on cumulative feed consumption was observed. The addition of organic increased villus height in the small intestines but the differences were not significant (𝑃<.05) in case of the ileum. Serum calcium and phosphorus concentrations were increased (𝑃<.05) but no effect (𝑃<.05) on the concentration of serum glucose and cholesterol, serum glutamic pyruvic transaminase (SGPT), and serum glutamic oxaloacetate transaminase (SGOT) was observed. The results indicated that the organic acid supplementation, irrespective of type and level of acid used, had a beneficial effect on the performance of broiler chicken.
