Effects of Zymotic Grape Seed Meal on Growth Performance, Slaughter Performance and Nutrient Utilization of Wulong Geese Aged from 5 to 12 Weeks
摘要
Abstract
This experiment was conducted to study the effects of different dietary zymotic grape seed meal level on growth performance, slaughter performance and nutrient utilization of Wulong geese aged from 5 to 12 weeks, to found the appropriate supplemental level of the zymotic grape seed meal and its feed effect. A total of 288 five-week-old Wulong geese were randomly divided into 6 groups with 6 replicates per group and 8 geese per replicate ( half male and half female ) . Geese in the 6 groups were fed the basal diet supplemented with 0 ( group Ⅰ) , 2% ( group Ⅱ) , 4% ( group Ⅲ) , 6% ( group Ⅳ) , 8% ( group Ⅴ) and 10% ( groupⅥ) zymotic grape seed meal, respectively. The experiment lasted for 8 weeks. At the beginning of 12 weeks age, forty-eight Wulong geese were randomly choosed from the 6 replicates and divided into 8 groups for meta-blic experiment. Groups Ⅰ to Ⅵ were fed the basal diet supplemented with 0, 2%, 4%, 6%, 8% and 10%zymotic grape seed meal, respectively. GroupⅦ was fed zymotic grape seed meal diet, and groupⅧ was fed grape seed meal diet. The results showed as follows: 1 ) compared with the group Ⅰ, the average daily gain ( ADG) in groups Ⅳ and Ⅴ was significantly increased ( P<0.05) , and the feed to gain was decreased ( P>0.05); the half eviscerated yield, percentage of eviscerated yield and percentage of leg muscle was significant-ly increased ( P<0.05 or P<0.01) , the percentage of abdominal fat decreased ( P>0.05) , the dressed percent-age and percentage of breast muscle increased (P>0.05). 2) The utilization of crude protein, ether extract, calcium, phosphorus, crude fiber, neutral detergent fiber and acid detergent fiber in groups Ⅳ and Ⅴ were significantly higher than that in groupⅠ( P<0.05 or P<0.01);the utilization of nitrogen in groupⅤwas sig-nificantly decreased ( P<0.05); there were no significant differents in the energy utilization among all groups ( P>0.05) . The utilization of crude protein, acid detergent fiber, crude fiber, calcium and phosphorus of zy-motic grape seed meal was significantly higher than that of unfermented grape seed meal (P<0.01), and the neutral detergent fiber availability was significantly increased ( P<0.05) . 3) Compared with the group Ⅰ, the total amino acid utilization in groupsⅣandⅤwas significantly increased ( P<0.05 or P<0.01) , and the most amino acid utilization in groupsⅣ and Ⅴ was significantly increased ( P<0.05 or P<0.01) . 4) The nano oli-gopeptide collagen utilization in groupsⅣ and Ⅴ was significantly higher than that in group Ⅰ ( P<0.05) . In conclusion, zymotic grape seed meal can improve the growth performance, slaughter performance and nutrient utilization of Wulong geese aged from 5 to 12 weeks, and the dietary appropriate supplemental level is 6% to 8%.关键词
