Abstract:
In the present study, the influence of dietary gamma aminobutyric acid (GABA) on production performance and duodenal villi height, crypt depth, and their ratios in commercial broilers were studied. A total of 192, day-old straight-run broiler chicks were divided into 4 treatment groups (T1, T2, T3, and T4) with four replicates of twelve chicks in each. T1 acted as the control. T2, T3, and T4 groups were supplemented with dietary GABA at 25, 50, and 75 mg per kg feed, respectively. The birds were reared under standard management conditions for 5 weeks (mean THI=75.0). Dietary GABA improved body weight in this study while there was no significant difference in FCR and carcass traits. A significant influence of GABA was observed only on the ratio of villi height to crypt depth.
