What causes diarrhea in piglets?

There is a case here that is basically the same as yours. The day before yesterday, a customer from Ningjin, Dezhou, Shandong Province called and said that the pigs at home had diarrhea again. More piglets had diarrhea, and the effect of antibiotics was not obvious. The mortality rate is very high, accompanied by fever, loss of appetite, rough coat, and some symptoms of coughing and asthma

The causes of diarrhea in pigs are as follows:

1. Pig physical problems

Due to imperfect digestive system function and the impact of weaning stress, piglets in the nursery period have damaged intestinal villi and insufficient gastric acid secretion, which makes them difficult to digest nutrients such as soybean meal protein in the feed. Diarrhea due to decreased ability.

2. Breeding environment

For example, the current temperature rises and falls suddenly. Piglets have very high requirements for the growth environment and are very sensitive to temperature, humidity and wind speed. They are easily affected by the weather. It is difficult to adapt to the sudden changes and cause diarrhea. Whether it is piglets or medium and large pigs, the environmental requirements must be kept within a certain range and remain unchanged to facilitate the rapid growth of pigs.

3. Feeding and management

1. Feed

(1) Feed moldy causes diarrhea.

(2) Excessive amount of protein soybean meal added to the feed or lack of vitamins and minerals can lead to diarrhea.

2. Management

(1) The structure of the pen is unreasonable, with poor ventilation, insufficient lighting, and the humid and dark environment of the pen is particularly conducive to the growth of bacteria. Prevent the invasion of feces and wind.

(2) When flushing the pens every day in summer, flush the pigs with cold water, which will cause stress to the pigs.

(3) Overfeeding diarrhea caused by starting feeds too late or after weaning.

3. Diseases

(1) Bacterial pathogens

Yellow dysentery in piglets is caused by Escherichia coli. It usually develops within 3 days of birth and the feces is gray. Yellow, yellowish-white, fishy smell, mushy,

Red dysentery in piglets is caused by Clostridium welchenii. It is easy to get sick about 7 days after birth. The feces is usually reddish brown, with a blood-like paste.

Piglet pullorum is caused by Escherichia coli. Generally, suckling piglets within 30 days of birth are susceptible to the disease, which is white-gray and mushy.

Piglet edema is caused by Escherichia coli. It appears within 1 to 3 days after weaning. The diarrhea is not obvious and there are neurological symptoms.

Add appropriate amounts to the nursery feed before and after weaning. Amoxicillin must be properly controlled when eating. The pigs of this customer's home are given "Zi Li Wuyou" orally for sows, and "Intestinal" for piglets. Under the premise of cooperating with the improvement of the environment, It has recovered now, and breeding focuses on management
