Abstract
To study the effects of different levels of protein and energy of diets on the growth performance and apparent rate of nutrient metabolism of Shihchih broilers,a total of 120 three-week-old Shihchih broilers were randomly divided into four groups, each group with three repeats. Chicks were fed with corn-soybean meal based diets in which the level of protein and energy were 12.09MJ/kg (18. 07%), 13. 09MJ/kg ( 18.01%),12.09 MJ/kg (20.08%), and 13.09MJ/kg (19. 93%) for groups I , II, III and IV ,respectively. The experiment lasted for 21 days. The results showed that the group IV had the highest level of average daily gain (ADG) and the lowest level of Feed/Gain (F/G) while the group I had the highest level of average daily feed intake (ADFI). Different levels of protein and energy diets did not significantly affect ADG (P>0. 05), ADFI (P>0. 05) and F/G (P>0. 05). The apparent utilization rate of crude protein, crude fat and calcium in group TV were the highest than the other groups,but the differences were not significant. Moreover the differences were not significant among the other groups (P>0. 05). The carcasses weight and leg muscles weight were significantly increased in group II and IV (P<0. 05). The all net weight loaded,half net loaded weight and slaughter rate were significantly improved in group II and IN (P<0. 05). According to the effects of diets on slaughtering performance and meat quality of Shihchih broilers,t're nutrition level of group II was the best.关键词
