Why does a sow refuse to eat and vomit? Causes and solutions

During pig farming, careful care is required, and in this process, many situations can arise that cause problems in sows. What should be done when a sow refuses to eat and vomits?

1. When a sow refuses to eat and vomits

First check whether the feed has become moldy, and promptly replace the moldy feed. For diseases such as gastritis and gastric ulcers, use astragalus polysaccharide and ceftiofur sodium for intramuscular injection, and inject Aimuer on the other side, once a day for 3 consecutive days. At the same time, administer omeprazole and domperidone orally. If eating is normal, it is recommended to mix 0.3% baking soda into the feed for one week. During the conditioning period, feed mild and nutritious feed, and add a mold remover to self-mixed feed. Finally, take good insulation measures.

If the feed nutrition is unbalanced, it is recommended to use probiotics or balanced protein to increase nutrients and avoid moldy feed.

2. Causes of vomiting in pigs

1. Porcine transmissible gastroenteritis is a highly contact-contagious viral infectious disease characterized by vomiting, severe diarrhea and high mortality in piglets under 2 weeks of age.

Prevention and control: Do not introduce breeding pigs carrying the disease, and carry out disinfection well. In winter, do a good job of cold protection and warmth, and pay special attention to strictly preventing draft intrusion during seasonal changes and sudden climate changes. From October to March of the following year, do a good job of vaccine injection. Transmissible gastroenteritis vaccine can be used, and it must be used according to the instructions. It is best to start preventing this disease from the sow, and implement an all-in-all-out system in management.

2. Porcine epidemic diarrhea is an infectious disease caused by a virus and characterized by vomiting and diarrhea. This disease mainly occurs in spring and winter, and also occurs occasionally in summer and autumn. Pigs of all sizes are susceptible, and it appears as an endemic epidemic.

Prevention and control: Drug treatment results are not ideal, so only symptomatic treatment can be used to prevent bacterial infection and improve the resistance of piglets.

3. Porcine pseudorabies is an acute infectious disease of pigs caused by pseudorabies virus. In adult pigs, the disease often appears as a latent infection or with catarrhal symptoms of the upper respiratory tract, while in pregnant sows it causes reproductive disorders, manifested as abortion, stillbirth or mummified fetuses, and weak piglets. Suckling piglets develop fever, encephalomyelitis and septicemia symptoms, and finally die.

Prevention and control: The most critical prevention and control method for this disease is to improve the pigs' own immunity. In addition to increasing nutrition, attention should also be paid to feeding management, especially doing a good job of vaccination against porcine pseudorabies. Pig farms with the conditions should monitor the antibody levels of the vaccine to ensure that the pigs themselves have sufficient immunity.

There are many causes of vomiting in pigs. Take certain measures according to the actual situation, and avoid blindness.
