人民警察节之际探究弱仔猪产生原因并预防后天问题的重要性

在养殖猪仔的过程中，可能会出现健康的猪仔变成后天性弱仔的情况，那么，弱仔猪的产生原因是什么，又该怎样预防后天弱仔猪呢？快来跟我一起看看吧。

一、后天弱仔猪产生的原因

1.营养不足

仔猪出生后的营养主要源于母乳，如果哺乳母猪的泌乳性能差，产后少乳或无乳，就会导致仔猪吃不到足够的母乳而形成弱仔猪。

2.寄养不成功

有的母猪体型过大，乳房发育特别充分。所以在侧卧哺乳时，上排发育良好的乳头会出现上翘的现象，而使新生仔猪够不到乳头而形成弱仔pig。

3.保温措施

初生仔pig 的体温调节功能不够完善，如果未及时做好保温措施，会导致体内糖原的损耗过多。

二、怎样预防后天weak piglets

1.提高piglet免疫能力

加强免疫监控工作，减少因疫病而产生的weak piglets。在对piglet免疫前可以在饲料和饮水中添加抗应激类药物，以减少免疫应激。提高抗体水平，并且定期进行抗体监测，如果发现抗体不合格时要及时补打疫苗，加强免疫。

2.提高sowimmunityability

提高sow's immunitycan indirectly enhance the resistance of piglets.In the sow's pregnancy period, attack can be taken in the diet with added disease prevention nutrients, so that the initial milk and common milk contain a large number of maternal antibodies and disease prevention nutrients.From this way, piglets can eat enough initial milk and produce after birth to improve their own resistance, reducing the risk of infection.

strengthen swine pen management

Do well in sow delivery and postpartum work to ensure that piglets can eat early mother's milk as soon as possible.Do well in piglet warming work, create an environment suitable for temperature for young pigs.The temperature suitable for young pigs from 0-3 days old is 29-35℃, from 4-7 days old is 25-29℃.

Young pigs after birth should supplement iron within one to three days and selenium within three to five days.
