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

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 ME1 3 .2 4 MJ/kg、CP1 3 %、Ca 0 .0 7%、P 0 .2 8%情况下 ,设计了每日每鸽保健添加剂饲喂量为 1 .5g 标准组 、2 g、2 .5g、3 g共 4个剂量组 ,与自配保健添加剂 对照组 1 .5g剂量 ,进行 1 2 0 d比较试验 .结果 :公鸽体重增加 94 .68± 74 .67g,比对照组 2 4 .68± 2 2 .69g,提高 2 .84倍 P<0 .0 1 ;母鸽体重增加74 .4 3± 3 8.85g,比对照组 1 5.63± 9.1 0 g提高 3 .76倍 P<0 .0 1 .青年鸽开产时间提早 5d,产蛋窝数提高 3 1 .75% ,种鸽育成率提高 4 0 % .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 .0 1 ,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 .

The experiment was made to study the effects of health feed additives on the young meat type pigeons.Four treatment groups and a control group were set for the 120 day long experiment.The four treatment groups were respectively provided 1.5 g(standard group),2 g,2.5 g or 3 g of the qualified health feed additives,which were designed according to the nutrition requirements of the meat type pigeons,per pigeon per day.It was supplied with the feed additives produced by unprofessional farmers(1.5 g/(pigeon·day))in the control group.All young pigeons for the experiment were fed on the basal diet mainly comprised of grain and soybean(ME 3.24 MJ/kg,CP 13%,Ca 0.07%,P 0.28%).After the 120 day long 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 group(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 onset of lay is 5 days earlier,the egg yield increases by 31.75%,the number of pigeons 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 additives satisfying standard nutrition requirements per day per pigeon. However,when young pigeons are provided more qualified health additives than the standard 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 egg 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 when they are fed with the additives produced by unprofessional farmers.
