In the summer and autumn alternation season, the temperature changes greatly. During this period, the diarrhea of ​​weaned piglets is high. How to prevent the diarrhea of ​​weaned pigs becomes a problem for pig farmers. Today, Xiao Bian conducts prevention and treatment on the physiological characteristics of weaned piglets.
First, the physiological characteristics of weaned piglets
1. Growth and development is rapid;
2. Poor body temperature ability;
3. Weaned piglets have low immunity;
4. The digestive organs are underdeveloped.
Second, breast-feeding weaning pig diarrhea prevention measures
1. Nutrients : The weaning and weaning pigs have a birth weight of about 1.5kg, 6.5-8kg at 3-4 weeks of weaning, and the weight gain is nearly 5 times. The nutrients that need to be supplied (giving nutrients rich, palatable, and digestible) Groove).
2. Insulation : The ability of breast-feeding and weaning pigs to resist cold is poor, especially when the autumn and winter seasons are replaced, and the diarrhea is presented on the second day of birth.
This is due to the low ambient temperature of the reborn weaned piglets. The ambient temperature for primary weaned piglets is 32-34 °C, while the suitable ambient temperature for pregnant sows is 18-22 °C.
Solution : In the first week of weaning pigs, two hooded heat lamps were hung on both sides of the pregnant sow. The hanging height was about 45 cm. The weaned pigs were opened when they were breastfeeding and turned off when they were breastfeeding. This takes care of both weaned piglets and pregnant sows.
3. Eat colostrum : Wash the nipple with 0.1% KMnO4 before breastfeeding to ensure the nipple is clean.
Colostrum and its characteristics: colostrum generally refers to the secretion of mammary glands within three days after the delivery of the pregnant sow. The difference between pig colostrum and normal milk is mainly milk protein content, up to 15.1% in colostrum and 5.5% in normal milk. This difference is determined by the high content of immunoglobulin in colostrum.
Immunoglobulin: This is a globulin with antibody activity or chemical structure similar to that of an antibody. It is one of the key components of the immune system. It plays an important role in the health and disease of reborn weaned piglets.
The above is the prevention and treatment measures for diarrhea of ​​breast-feeding and weaning pigs that are organized by Huinong.com, and I hope to help you.
