What are the causes of sub-health in sows and what preventive measures are there?

Sub-health in sows refers to a state in which the sow's body structure and physiological functions are declining, which can lead to a serious reduction in pig farm production efficiency, cause frequent outbreaks of various diseases, and affect the economic benefits of the pig farm. So what causes sub-health in sows? How should it be prevented? Let's take a look together.

I. Causes of sub-health in sows

1. Unreasonable feed formulation

Some farmers excessively pursue growth speed, feed conversion rate and body weight. Under short-term interests, they excessively increase the feeding amount and nutrient concentration, resulting in pigs becoming too fat or their health being seriously affected.

2. Presence of immunosuppressive diseases

In addition to directly harming the health of the pig herd, immunosuppressive diseases can also cause immunosuppression in the body, allowing other pathogens and viruses to invade, causing secondary infections, worsening the condition and leading to vaccination failure.

3. Moldy feed

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

4. Poor rearing environment

Both too high and too low temperatures will cause a certain degree of stress to pigs. When sows are in a high-temperature or low-temperature environment for a long time, they will be in a stress state of adapting to an adverse environment, thereby leading to sub-health. When sows are in a poorly ventilated environment for a long time, the content of harmful gases increases, which can easily cause chronic poisoning in sows, weakening their resistance to disease, and even causing acute poisoning.

5. Invasion of external pathogens

After the pig herd is infected with external pathogens, it can only adapt to this balanced state by gradually adapting and producing corresponding antibodies. During the process of producing antibodies, the resistance of the pig herd will also be affected to varying degrees, resulting in sub-health.

II. Preventive measures

1. Strengthen environmental control of the pig house

Because sows bear enormous production pressure, they should be kept in a quiet, comfortable environment with good air quality as much as possible, so that their production potential can be maximized.

2. Eliminate immunosuppressive sources

When introducing breeding stock, attention should be paid to the sow quarantine procedures. On the other hand, purification work for porcine reproductive and respiratory syndrome and porcine circovirus should be done for existing sows, and sow antibodies should be tested regularly.

3. Establish a complete health care and prevention plan

The goal is to eliminate pathogens in the sow's body, inhibit viral replication, enhance sow immunity, purify infectious diseases in the pig farm, promote normal estrus in sows, and increase the number of piglets born.
