早期断奶仔猪的消化生理及饲粮组合研究

Study on Digestive Phsiology and Forage Combination of Early weaning Piglets

仔猪早期断奶受心理、环境及营养应激影响,常表现为"仔猪早期断奶综合症"。主要是营养应激,即仔猪由液态母乳转向固体饲料。由于仔猪消化系统尚未发育成熟,不能适应这种营养物质的骤变。因此配制适合早期断奶仔猪消化生理的饲粮是克服早期断奶综合症的最有效方法。

Early-weaning of piglets was a concernedly advanced technology in intensified pig farming. This technology can improve reproductive rate of swine, decrease the spread of diseases from the parent to piglets and improve production performance and carcass quality. The piglets weaned in three to five weeks after birth in higher raising lever. At present,The method weaned in two weeks after birth have been spreaded and applied in the developed country. The piglets often displayed syndrome of piglets early weaning because they were influenced upon from liquid breast which had bad odour and abundant nutrt toon to solid forage which had had odalr and solid texture. Butthe disgestive system of piglets did not develop maturedly in this moment and adjust to the violet change of nutritious material. So it is the most effective method overcome the syndrome of early weaning theat the forage was compounded to fit the need of digestive physiology of early weaning
