| 摘 要： | 仔猪生后1—20公斤的生长阶段,是养猪生产营养关键期。这一时期给仔猪补食,在生产实践上促进早期断奶的完成,缓解同窝多仔养分不足的矛盾。在营养理论上,根据仔猪生长发育快的生物学特点(Wkg≈2WK)。满足仔猪高能高蛋白的需求,克服仔猪消化功能不全的弱点;根据仔猪代谢能利用率高的营养代谢特点(Kpf=0.8),充分挖掘仔猪的生长潜力。在经济上获得饲料/增重约1:1的效果。要获得较好的补饲效果,必须有优质高效的预混料与之配合,因此,应从氨基酸、维生素,微量元素、消化酶、抗菌素和矫味剂等方面对仔猪补饲的预混料配方开展研究

| Abstract: | The growth period of piglets from 1 to 20 kg live weight is nutritionally the most critical period in the pig production. Caused by a largo litter sizetheinsufficient nutrients and energy intake in this period is usually supplemented by creep feeding. Furthmore, the intake creep feeding is necessary for development of the digestive system in the piglets and improves physiological conditions of the piglets for early weaning. Economically, the creep feeding benefits from a high feed utilization as the ratio of feed intake to live weight gain is usually 1: 1. However, the creep feeding can not give satisfactory results without an efficient premix in the diet. The optimum composition of the premix in respect to amino acids, minerals, vitamins, enzymes, antibiotics and others is essential in order to achieve satisfactory growth and development of the piglets. Therefore, the premix formulation for the creep feeding needs intensive and careful studies. |
