Abstract

An experiment was conducted to evaluate the effects of dietary coated-benzoic acid on leg health of broilers and physicochemical property of bedding. A total of 2 400 Arbor Acres chicks were randomly distributed into 2 groups with 12 replicate pens per group and 100 birds (male: female was 1:1) per pen at 1 day of age. The broilers in control group were fed basal diets, and in experimental group were fed basal diets supplemented with 500 g/t coated-benzoic acid. The trial lasted for 35 d. At 35 days of age, 10 chicks per pen were selected for footpad and hock assessments, and the humidity, pH and total nitrogen (TN) content of bedding samples were measured in each pen. The results showed that dietary supplementation of 500 g/t coated-benzoic acid significantly reduced the occurrence of footpad and hock injury (P<0.05). Moreover, coated-benzoic acid significantly decreased the pH and TN content (P<0.05) of bedding whereas the humidity remained unaffected (P>0.05). In conclusion, the current research reveals that dietary supplementation of coated-benzoic acid decreases the incidence of footpad and hock injury and considerably influences the physicochemical property of bedding. The welfare of the broilers is improved by coated-benzoic acid.
