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's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，加减少因疫病而产生weak piglets。在对piglet进行免疫前，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immunity.
2.提高sow immunization levels
提高sow's immune force, can indirectly enhance the resistance of piglets.To sow after pregnancy period attack can add anti-disease nutrients in the feed, to improve initial milk and regular milk of sow source antibody quantity and content of disease prevention nutrient.To make sure that the piglet can eat enough initial milk and produce after birth, increase its own resistance, reduce infection disease probability.
Strengthen farm management
Do a good job in sow delivery and postpartum work, ensure that piglets can eat early mother's milk as soon as possible.Do a good job in keeping warm for piglets.Create an environment suitable for temperature for young pigs.The actual production temperature from 0-3 days old is 29-35℃;4-7 days old is 25-29℃.Piglets should be supplemented with iron within the first three days after birth;with selenium within three to five days.
Let us together explore why weakling pigs occur during their rearing process and how we may prevent them!
