鸽蛋人工孵化和仔鸽并窝的试验研究

An experimental study of artificial incubation of pigeon eggs and young pigeons' co-nesting

研究了鸽蛋人工孵化和仔鸽并窝对产鸽生产性能的影响。试验结果表明：鸽蛋人工孵化可有效减少破蛋率，降低死胎率，出雏率提高12．2％（P〈0．05）．同时，使产蛋周期缩短30d，差异极显著（P〈0.01）；并窝3只的乳鸽体重增长与非并窝的乳鸽相似，但饲料报酬明提较高，重料比差异极显著（P〈0．01）;并窝4只的仔鸽饲料报酬高，但乳鸽增重较慢。说明一对亲鸽完全有可能同时哺喂3～4只仔鸽，但以每窝并至3只仔鸽较理想。

This paper studies the influence of artificial incubation of pigeon eggs and co-nesting of young pigeons on the production of pigeons. The experiments indicates： the artificial incubation of pigeon eggs can effectively decrease the rate of broken eggs and dead fetus, increase the birth rate by 12.2M （P〈05）. Meanwhile, it can shorten the period of egg-laying to 30d （P〈0. 01）. The weight of 3 co-nesting pigeons and non-nesting pigeons is similar, but the repayment of fodder evidently increases （P〈0.01）. The repayment of 4 co-nesting pigeons fodder is also high, but they grow more slowly and weigh more lightly. This shows that a couple of pigeons can feed 3-4 young pigeons at one time, but 3 nesting pigeons is more idealistic.
