In pig production, the observation of feces can often have a preliminary understanding of the health of the herd, such as the softness and hardness of the feces, color, smell, different states, the digestive function of the digestive system, so as a farmer Special attention should be paid to the state of feces during routine inspections of pig houses and a reasonable analysis.

Today we talk about a condition of abnormal feces, that is, blood in the stool. What is the reason for this? How to deal with this situation? According to the state of feces, it is divided into dry blood and loose blood, which is divided into reddish blood according to blood color, and dark red or black blood.

Dry stools with blood, often accompanied by pus, is the dry stool on the surface of the pus mixed bloodshot, which is caused by constipation of rectal inflammation. The dark red color in the loose stools indicates the middle part of the intestine, mainly the ileum, which is ileitis.

The blood in the stool is bright red, suggesting that the end of the intestine is bleeding, mainly in the colon stage. It is colitis, which is the most common "pig bloody".

If the pigs only have black soy sauce-like stools and the body surface is whitish, the appetite is weak, generally suggesting that the stomach is bleeding, there are acute and chronic types. Stomach hemorrhage and rectal injury are relatively rare, and generally show a sporadic state, which will not cause great harm to pig production. The clinical cause of raising pigs is that ileitis caused by Lawsonia intracellularis and colitis caused by Treponema pallidum.

How to distinguish between these two diseases?

1, the difference in bleeding sites, the color of blood in the stool is somewhat different

The site of ileitis is located in the ileum stage. When the blood is excreted, it passes through a relatively long intestine. Because of the action of enzymes in the digestive tract, the blood is denatured and becomes dark red or black. After bleeding from colitis, the blood can be quickly excreted, so most of what we see is bright red blood. However, some acute episodes of inflammation also present acute bleeding, which is bright red and is not easily distinguished from colitis.

2. Hemorrhagic disorders are different in the stage of the herd

Intracellular Lawsonia is more likely to infect pigs or gilts in the middle and late stages of fattening. Treponema is more likely to infect piglets that are just weaned or pigs that are in pre-conservation. Therefore, the diagnosis can be distinguished by different age stages of blood drawing. Blood stasis within 70 days of age is colitis caused by Treponema pallidum infection, and blood stasis occurring at 70 days or older including gilts is ileitis caused by Lawsonia intracellularis.
