摘　　要：试验旨在研究优化颗粒保健砂对肉鸽产蛋率、受精率及孵化率等产蛋性能影响。通过对产蛋性能统计,确定了一份完整保健砂营养组分。结果显示:与对照组相比,粉剂保健砂组肉鸽的产蛋数、产蛋率、受精率极显著提高(P<0.01);颗粒保健砂与粉剂保健砂相比,饲喂颗粒保健砂肉鸽的产蛋数、产蛋率、受精率显著提高(P<0.05);推广使用颗粒保健砂30 t,饲喂肉种鸽2万对,比上一年同期产蛋率提高16.73%,种蛋受精率达23.72%。研究表明,饲喂颗粒保健砂能够有效提高肉鸽生产性能和养殖经济效益。The experiment was to study the effect of optimized granular health sand on laying performance of meat pigeons, such as laying rate, fertilization rate and hatching rate. A complete nutritional composition of health sand was determined by statistics of egg production performance. The results showed that compared with control group, the laying number, laying rate and fertilization rate of pigeons in powder sanding group were extremely increased(P<0.01).Compared with powder health sand, the laying number, laying rate and fertilization rate of pigeons fed with granular health sand were significantly increased(P<0.05). Twenty thousand pairs of meat pigeons were fed with 30 t granulated health sand, the laying rate increased by 16.73% compared with the same period of last year and fertilization rate of breeding eggs reached 23.72%. The experiment indicates that feeding granular health sand can effectively improve the production performance and economic benefits of meat pigeon breeding.
