饲粮中添加啤酒花渣对肉仔鸡死淘率的影响

目的]探讨啤酒花渣对内仔鸡死淘率的影响.方法]试验选用300只1日龄AA肉鸡,各试验组在饲粮中分别加入0％、4％、8％、12％、16％和20％啤酒花渣.结果]各组0～3周、4～6周和全期死淘率从高到低依次为：2组＜3组＜l组＜4组＜6组＜5组.0～6周2组、3组肉鸡全期死淘率比1组增加73.3％和16.7％,而4组、5组、6组比1组分别降低60.0％、93.0％和86.7％.结论]在肉仔鸡饲粮中添加12％、16％和20％啤酒花渣,可以降低肉仔鸡的死淘率.

Effect of Hop Residue Supplementation on Dead and Discarded Rate of Broilers

Objective] To investigate the effect of hop residues on dead and discarded rate.Method] A total of 300 AA male broilers were selected,adding 0％,4％,8％,12％,16％,20％ hop residues into each group.Result] The order of dead and discarded rate is 2 group ＜3 group ＜ 1 group ＜ 4 group ＜ 6 group ＜ 5 group.The dead and discarded rate of 2 group and 3 group is higher of 73.3％ and 16.7％ than 1 group,while 4 group,5 group and 6 group is lower of 60.0％,93.0％ and 86.7％ than 1 group.Conclusion] Adding 12％,16％ and 20％ hop residue into broilers feed could decrease dead and discarded rate.
