Abstract
This research report investigated the influences of diet supplemented with sodium diacetate (SD) on growth performance, carcass characteristics, meat quality, and intestinal pH and Escherichia coli count of broilers. A total of 240 1-day-old Arbor Acres chicks were randomly allocated into four groups fed with basal diets containing 0% (Control group), 0.01%, 0.03%, and 0.05% SD. At 42 days of age, the final weight, bodyweight gain, pre-evisceration weight, eviscerated weight, and breast muscle weight were increased in the 0.05% SD group compared with the Control group (P < 0.05). The 0.05% SD group also showed an increased water-holding capacity in the breast and thigh meat (P < 0.05). However, this group also showed a decrease in the lightness value of thigh meat (P < 0.05). There was a tendency towards a decrease in pH values of duodenum, jejunum, ileum, and appendix with the increase in SD supplementation (0.01–0.05%). Broilers in the 0.05% SD group had a lower pH in the jejunum than those in the Control group (P < 0.05). SD supplementation in diets decreased the E. coli count in the small and large intestines (P < 0.05). This study suggests that SD supplementation in diets provides a nutritional strategy to improve growth performance, carcass characteristics, meat quality, and intestinal health of broilers.
