摘　　要：试验旨在研究白羽王鸽种鸽哺育前体重对哺育期减重和乳鸽生长性能的影响。采用单因子试验设计,选用120对健康种鸽,按哺育前体重由大到小分为A、B、C和D四个处理组,每组6个重复,每重复5对种鸽。采用"2+4"生产模式,饲喂全价颗粒饲料,预饲10 d,试验期20 d。结果显示:试验第1~10天,A组母鸽减重显著高于D组(P<0.05),母鸽哺育前体重越大,减重越多;试验第11~20天,不同体重公鸽减重、母鸽减重和公母鸽总减重均差异不显著(P>0.05);试验第1~20天,A组公鸽减重显著低于B组公鸽(P<0.05),A、C组母鸽减重显著高于D组(P<0.05),B组公母鸽总减重显著高于D组(P<0.05)。白羽王鸽种鸽体重对乳鸽5、10、15和20 d末重均无显著影响(P>0.05),从数值上看以B组种鸽哺乳效果最好。公、母鸽初始体重与乳鸽5、10、15、20 d末重均无显著相关性(P>0.05),公、母鸽减重与乳鸽平均日增重无显著相关性(P>0.05)。综上所述,母鸽哺育前体重能影响母鸽哺育期减重,哺育前种鸽体重对公鸽减重和乳鸽生长性能影响不大。The experiment was conducted to study the effects of body weight of white king pigeon （Columba liva） on brooding weight loss and growth performance of squabs. A total of 120 white king pigeons were allotted into four groups（A, B, C and D）by weight from heavy to light. Each group had six replicates and five pigeons in each replicate. Pigeons were fed processed-pellet, adopt ＂2＋4＂ production modes. The experiment lasted for 30 days with 10-day adaptation and 20-day trial period. The results showed that： During days 1 to 10,compared with group D,body weight of the female pigeon of group A was significantly decreased （P〈0.05）. During days 11 to 20, there was no significant difference in weight loss among four groups （P〉0.05）. During days 1 to 20,compared with group B,male pigeon of group A had a significantly less weight loss （P〈0.05）; Compared with group D,male pigeon of group A and group C had significantly more weight loss （P〈0.05）,and the weight loss of total pigeons of group B were significantly increased （P〈0.05）. Initial body weight of breeding pigeons had no significant difference on body weight of squabs on days 5,10,15,20 （P〉0.05）,which had no significant correlations （P〉0.05）,and squabs of group B had heavier body weight. The results indicated that initial body weight of breeding female pigeon could affect weight loss of brooding period, and initial body weight of breeding pigeon had little influence on weight loss of male pigeon and growth performance of squabs.
