摘要
鸽子属晚成鸟,雏鸽从出生到28日龄靠亲鸽分泌的鸽乳喂养。鸽乳是一种高蛋白、高脂肪的乳酪状物质,其分泌受催乳素控制。在分泌过程中,亲鸽嗉囊组织增生,血管化现象显著。研究表明,雏鸽代谢能需求为12.5~13.5 MJ/kg,粗蛋白20%~22%,而成年鸽代谢能需求为11.5~12.0 MJ/kg,粗蛋白12%~18%。目前成年鸽的饲料类型有原粮饲料型、全价颗粒料型和平衡用配合饲料型,不同类型的饲料对成年鸽的生产性能存在一定影响。文章综述了鸽乳的组织生物学基础和营养特征,雏鸽与成年鸽的营养参数需求量以及成年鸽饲料类型和应用,对肉鸽业生产具有一定的参考意义。
As an ahricial bird, pigeon squabs were fed ＂crop milk＂ produced by parent pigeons until twenty-eight days of age. ＂crop milk＂ was a type of cheese-like substance and triggered by prolactin, which has high concentration of protein and lipid. During its secretion, crop tissue of parent pigeons became bigger and was full of vessels. The nutrition level of metabolic energy in squabs should be from 12.5 to 13.5 MJ/kg, and its crude protein was from 20% to 22%. As to adult pigeons, the two nutritional levels should be from 11.5 to 12 MJ/kg, and 12% to 18% of protein. The feeding choices of adult pigeon included seeds, formulated diets and balanced diets. This followings are biological characteristics and nutrient composition of ＂crop milk＂, nutrient requirements of squabs and adult pigeons, and the application of feed in pigeon production. The review will support the pigeon industry in our country.
