The effects of 5 different feeding systems on the performance, carcass traits and organ development were studied in pigeon squabs. The 5 treatments were (1) whole grains of maize, pea and wheat plus concentrate feed; (2)whole grains of maize and wheat plus concentrate feed (CWC); (3) whole grains of maize and pea plus concentrate feed; (4)whole grain of maize plus concentrate feed (CC); and (5) compound feed (CF). Feed intake of parent pigeons increased significantly from 0 to 21 d and it was higher in the CF treatment. Body weight of squabs in the CWC treatment was the highest among the 5 treatments in 4 weeks. Body weight losses of parental pigeons during the rearing period were not significantly different among the 5 treatments. Protein intake in CC and CWC treatments was lower than that of the other three treatments. The CWC treatment had the highest daily weight gain and the lowest feed conversion ratio. Treatments were statistically similar in the relative weight of carcass, breast and thigh. CF had the lower relative weight of abdominal fat. Relative weight of gizzard in the CF treatment was significantly lower than that of CWC. It was concluded that the application of free choice feeding of whole grains of maize and wheat plus concentrate feed increased the body weight of 28-d-old pigeon squabs and decreased the feed conversion rate of parent pigeons. This feeding strategy could be commercially interesting in meat-type pigeon production.
研究了5种不同饲养系统对乳鸽生产性能、胴体性状和器官发育的影响。5种处理分别为:(1)玉米、豌豆和小麦全谷物加浓缩饲料;(2)玉米和小麦全谷物加浓缩饲料(CWC);(3)玉米和豌豆全谷物加浓缩饲料;(4)玉米全谷物加浓缩饲料(CC);(5)配合饲料(CF)。亲鸽采食量在0至21日龄时显著增加,且CF处理的采食量更高。CWC处理的乳鸽体重在4周龄时是5种处理中最高的。5种处理中亲鸽育雏期体重损失无显著差异。CC和CWC处理的蛋白质摄入量低于其他三种处理。CWC处理的日增重最高,饲料转化率最低。各处理在胴体、胸肉和大腿的相对重量上在统计学上相似。CF处理的腹部脂肪相对重量较低。CF处理的肌胃相对重量显著低于CWC处理。得出的结论是,采用玉米和小麦全谷物加浓缩饲料自由采食的方式可提高28日龄乳鸽的体重,并降低亲鸽的饲料转化率。这种饲养策略在肉鸽生产中可能具有商业价值。
