| Abstract | ||||
| The present study was conducted to examine the effect of selenium sources on growth performance, carcass criteria and physical meat quality of broiler chickens. A total of 192 One-day old broiler chickens were randomly distributed into four equal treatment groups. Treatment groups were fed a control diet, a control diet supplemented with selenomethonine (0.3 mg /kg), control diet supplemented with Sodium-Selenite (0.3 mg /kg), or control diet supplemented with Nano-Selenium (0.3 mg /kg). The feeding trial lasted for 35 days. Each treatment had six replicates with eight birds each. Broilers fed the diets supplemented with selenium sources increased body weight and body weight gain and improved (P<0.05) feed conversion ratio than those fed the control diets. Broilers fed the diets supplemented with Nano-Selenium had higher body weight and body weight gain and lower (P<0.05) feed conversion ratio than those fed the control diets or diets supplemented with selenomethonine and sodium selenite. Additionally, broilers fed the diets supplemented with different sources of selenium at 0.30 mg/kg had improved meat quality in leg muscle than those fed the control diets. Furthermore, broilers fed the diet supplemented with different sources of selenium improved dressing percentage and abdominal compared to control, but no differences (P<0.05) were observed in internal organs among treatments. Overall, Nano-selenium resulted in best performance. The results from the present study indicated that supplemental selenium improved the growth performance, physiochemical meat quality and carcass criteria of broilers; and the Nano-selenium was more effective than the Se from selenomethonine and sodium-selenite. | ||||
