Effects of Feed-Used Mannanase Transgenic Corn on Growth Performance, Carcass Performance and Blood Physiological and Biochemical Indexes of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of mannanase transgenic corn on growth performance, carcass performance and blood physiological and biochemical indexes of broilers.A total of 480 one-day-old Arbor Acres ( AA) broilers were randomly allocated to 4 groups, with 6 six replicates per group and 20 broilers per replicate.The four groups showed as follows: group Ⅰ, broilers fed non-transgenic corn without addition of mannanase as the control; group Ⅱ, broilers fed non-transgenic corn with addition of mi-crobial mannanase at low dosage of mannanase activity ( 500 U/kg);groupⅢ, broilers fed mannanase trans-genic corn with low dosage of mannanase activity (500 U/kg); and group Ⅳ, broilers fed mannanase trans-genic corn with high dose of mannase activity ( 5 000 U/kg) .The trial lasted for 42 d.The results showed that the average daily gain of broilers aged of 42 days in groups ⅢandⅣwas significantly higher and the ratio of feed to gain was significantly lower than those in control group (P<0.05).Slaughter percentage, eviscerated percentage of broilers aged of 42 days in group Ⅳwere significantly higher than those in groupⅡand control group( P<0.05) .No significant differences were observed among the 4 groups in blood physiological and bio-chemical indexes (P>0.05).It is concluded that diet added mannanase transgenic corn can significantly im-prove the growth and carcass performance of broilers, while has no significant effects on the blood physiologi-cal and biochemical indexes.关键词
