白羽王鸽不同育雏数量的生长情况比较

Comparison of growth on different numbers of suckled nestling pigeons of american King pigeon

以贵州省惠水县龙翔鸽业有限公司的白羽王鸽种鸽及其所产仔鸽为研究对象,从3 000多对种鸽中随机选取125对,并对其270只仔鸽分别进行生物学特性观察和生长情况测定.结果表明,5～9日龄各组雏鸽处于生长高峰期;自然育雏0～15日龄试验Ⅰ组和Ⅱ组与对照组在增重方面差异显著(P<0.05);15日龄后经人工育肥,试验组与对照组的平均日增重接近(P＞0.05).表明自然育雏以每窝2只为好,人工哺育以每窝3只为好,可缩短繁殖周期,提高生产效率.

270 nestling pigeons from 125 couples of adult pigeons were divided into three groups,grouplwith 1 nestling pigeons and one couple of adult pigeon,group Ⅱ with 3 nestling pigeons and one couple of adult pigeon, group Ⅲ as a control with 2 nestling pigeons and one couple of adult pigeon, to observe their biological attributes and compare their growth sit- uation. The results showed that the 5 -9^th day-pigeons have the highest growth speed; Group I and Ⅱ have a significant difference（ P 〈0.05 ） compared with the contrast one in BG during 0 -15^th days; After the 15^th day, the experimental groups have similar ADG compared with the contrast one（ P 〉 0.05 ）. It is verified that 2 nestling pigeons with one couple of adult pigeon is better than others when natural suckling,but 3 nestling pigeons with one couple of adult pigeon is better than others when artificial suckling,the reproduction circle can be shorten and productive rate can be improved.
