肉鸽体重蛋重与乳鸽增重规律的观察

Observation on the Body Weight,Egg Weight and Squab Weight Increasing of Pigeon

母鸽体重平均为652g,平均蛋重为22.57g,它们之间的相关系数为0.303(P<0.01).肉鸽每窝所产的2枚蛋,第2枚大于第1枚0.75 g(P<0.01).初生重占蛋重的比例为77.68±7.45%.乳鸽初生重与3、4周龄体重呈弱相关:蛋重与乳鸽初生重,1,3,4周龄体重呈中等相关;2周龄与3、4周龄及3与4周龄体重均呈强相关(P<0.01).肉鸽的快速生长期在第1～2周,第4周生长减慢,增重只有52.47g.

65 pairs of pigeon were involved in the study,and their body weight(BW),egg weight(EW),initial weight(IW)and 1～4 week BW of squab were measured. The result showed that average BW of female pigeon and EW were 625g and 22.57g,respectively,the related coefficient of both of them was 0.303(p<0.01). Of the two eggs of each brood,the weight of latter77.68±7.45%. IW and 3,4 week BW were weakly related,EW and IW,1,3,4 week BW were medium related,but 2 week BW and 3,4 week BW or 3 week BW and 4 week BW were highly related. The fastest BW increasing period of squab was among 1 to 2 week,BW increasing in the fourth week was weak,averaged about 52.47g.
