摘要
仔猪断奶一般是在出生后4～6周，仔猪断奶期间仔猪的免疫机制和肠道形态都会发生变化，所以这个阶段是抵抗力最低的阶段。饲料中添加药物可有效预防各种细菌的继发感染，降低发病率或减轻发病程度，因而能够有效降低死淘率，提高经济效益。同时在仔猪断奶期间合理饲喂教槽料和高浓度营养日粮，结合良好的饲养管理和环境控制降低应激反应的影响，保证仔猪的营养，可尽量提高仔猪的抵抗力。
Piglets bigin to wean at about 4 -6 weeks old, and many changes have taken place in weaning piglets＇ immunity functions and intestinal tract morphous in this periods. So the resistance of piglets is minimal at this time. Adding medicine to annimal feed can prevent various kinds bacterial secondary infection as well as degrade attack rate or less the morbidity, so by this way we can degrade the piglets death rate and increase economic returns. During the weaning, feeding weaning piglets reasonably with piglet feed and high concentration nutrition diet combined- ing the favourable breed management and environmental control can depress the impact of stress reaction , by this way we can ensure piglets nutrition as far as possible raise the piglets power of resistance.
