초록
The present study was carried out to investigate the effects of feeding dietary legislation sulfur on the lipid levels of chicken meat and growth performance in broilers. A total of 180 male broilers (Ross strain 308) were randomly assigned into three treated groups with triplicate of 20 birds each, T1 (control group), T2 (antibiotics 8 ppm), and T3 (0.3% sulfur premix containing 30% of sulfur) groups. The body weight gains over a 3-wk period were significantly higher in T2 and T3 groups than the T1 group, but not different between T2 and T3. The dressing percentage, weight of thigh meat, breast muscle and bursa of F were significantly high in T2 and T3 groups compared to the T1 group, but not different between T2 and T3. The weight of abdominal fat was significantly higher in T3 group than in T1 and T2 groups. The cholesterol content of the whole chicken meat was significantly lower in the T3 group as compared to the T1 and T2 groups. The oleic acid (18:1n-9) content of whole chicken meat from the T3 group was higher than that of the other groups. The results of this study suggests that feeding dietary sulfur as an antibiotic replacement may increase the oleic acid and reduce the cholesterol in chicken meat while improving the carcass characteristics and growth performance in broiler chickens
Abstract
The present study was carried out to investigate the effects of feeding dietary legislation sulfur on the lipid levels of chicken meat and growth performance in broilers. A total of 180 male broilers (Ross strain 308) were randomly assigned into three treated groups with triplicate of 20 birds each, T1 (control group), T2 (antibiotics 8 ppm), and T3 (0.3% sulfur premix containing 30% of sulfur) groups. The body weight gains over a 3-wk period were significantly higher in T2 and T3 groups than the T1 group, but not different between T2 and T3. The dressing percentage, weight of thigh meat, breast muscle and bursa of F were significantly high in T2 and T3 groups compared to the T1 group, but not different between T2 and T3. The weight of abdominal fat was significantly higher in T3 group than in T1 and T2 groups. The cholesterol content of the whole chicken meat was significantly lower in the T3 group as compared to the T1 and T2 groups. The oleic acid (18:1n-9) content of whole chicken meat from the T3 group was higher than that of the other groups. The results of this study suggests that feeding dietary sulfur as an antibiotic replacement may increase the oleic acid and reduce the cholesterol in chicken meat while improving the carcass characteristics and growth performance in broiler chickens
