肉鸽保健添加剂对青年鸽生长的影响研究

摘要

The experiment was made to study the effects of he alth feedadditives on the young meat type pigeons.Four treatment groups and a c ontrol group were set for the 120-day-long experiment.The four treatment group s were respectively provided 1.5 g(standard group),2 g,2.5 g or 3 g of the qualifi ed health feed additives,which were designed according to the nutrition requirem ents of the meat-type-pigeons,per pigeon per day.It was supplied with the feed a dditives produced by unprofessional farmers(1.5 g/(pigeon*day))in the control g roup .All young pigeons for the experiment were fed on the basal diet main ly comprise d of grain and soybean(ME 3.24 MJ/kg,CP 13%,Ca 0.07%,P0.28%).After the 120-day-lo ng experiment,the increase of the body weight of male pigeon in treatment groups (94.68±74.67 g)is 3.84 times when compared with the increase of the control gro up(24.68±22.69 g)(P＜0.01).The increase of the body weight of female pigeon (74.43±38.85 g)is 4.76 times compared with the increase of that in the control group(15.63±9.10 g)(P<0.01).Comparing to the control group,the age of onse t of lay is 5 days earlier,the egg yield increases by 31.75%,the number of pigeo ns fit for breeding increases by 40% in the experimental young meat type pigeons. The best feeding result is attained through 1.5 g qualified health addi tives satisfying standard nutrition requirements per day per pigeon. However,whe n young pigeons are provided more qualified health additives than the stand ard requirements, the increase of body weight of them decreases significantly( P<0.01)and the number of pigeons fit for breeding is affected,whereas the eg g yield is not.A significantly negative effect on the health,on the growth and development,and on the reproduction of the young meat type pigeons is found whe n they are fed with the additives produced by unprofessional farmers.%在用谷物豆类原粮饲喂白羽杂交王鸽青年鸽日粮营养水平ME13.24MJ/kg、CP1 3%、Ca 0.07%、P 0.28%情况下，设计了每日每鸽保健添加剂饲喂量为1.5 g(标准组)、2 g、2.5g、3g共4个剂量组，与自配保健添加剂(对照组)1.5g剂量，进行120d比较试验。结果：公鸽体重增加94.68±74.67g，比对照组24.68±22.69g，提高2.84倍(P＜0.01)；母鸽体重增加74.43±38.85g，比对照组15.63±9.10g提高3.76倍(P＜0.01)。青年鸽开产时间提早5d，产蛋窝数提高31.75%，种鸽育成率提高40%。按肉鸽营养标准配制保健添加剂每日每鸽喂量以1.5g达到理想效果，饲喂量超过标准需要量和实践添加量，青年鸽增重呈明显下降趋势(P＜0.01)，对种鸽育成数有影响，而对产蛋窝数并没有明显影响，自配保健添加剂对青年鸽的健康、生长发育和繁殖都有负面明显影响。
