肉鸽保健添加剂对青年鸽生长的影响研究

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。

Effects of Health Additives in Feed on Young Meat Type Pigeon Growth

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.
