Causes of sub-health of sows and preventive measures

Sow sub-health means that sows are in a state of decline in body structure and physiological function, which will seriously reduce the production efficiency of pig farms, resulting in frequent occurrence of various diseases, and breeding will affect the economic benefits of pig farms. So what is the cause of sow sub-health? How to prevent it? Let's take a look.

1. Causes of subhealth of sows

1. The feed ratio is unreasonable.

Some farmers excessive pursuit of growth rate, feed rate and body weight, in the short-term benefits, excessive increase in feed and nutrient concentration, resulting in overweight pigs or seriously affected health.

2. Immunosuppressive disease exists.

Immunosuppressive disease not only directly harms the health of pigs, but also causes immunosuppression, makes other bacteria and viruses invade, causes secondary infection, aggravates the disease and fails vaccination.

3. Feed mildew

If you feed moldy feed during feeding, it will have a great impact on pigs. As long as the temperature of the mold in the feed is above 10 degrees and the feed moisture is above 11.5%, it can grow and reproduce in large quantities, causing serious harm.

4. the breeding environment is bad.

Too high and too low temperature will cause certain stress to pigs. When sows are in a high or low temperature environment for a long time, they will be in a stress state of poor adaptation to the environment, resulting in sub-health. When sows are in a poorly ventilated environment for a long time, the content of harmful gases increases, which is easy to cause chronic poisoning of sows, weakening their resistance to disease, and even acute poisoning.

5. Invasion of foreign pathogens

After infected with foreign pathogens, pigs can only adapt to this equilibrium state by gradually adapting and producing corresponding antibodies. In the process of producing antibodies to them, the resistance of pigs will also be affected in varying degrees, resulting in sub-health.

II. Preventive measures

1. Strengthen the environmental control of pig houses.

Because sows bear great production pressure, so try to make sows live in a quiet, comfortable, good air quality environment, so as to maximize their production potential.

2. Clear immunosuppressant

During introduction, attention should be paid to the quarantine procedures of sows, on the other hand, the purification of blue ear disease and circovirus of pigs should be done well in the original sows, and the antibodies of sows should be tested regularly.

3. Establish a perfect health care and prevention plan.

The goal is to remove pathogens from sows, inhibit virus replication, enhance sow immunity, purify infectious diseases in pig farms, promote normal estrus and increase litter size.
