Causes and Prevention of Enteric Syndrome
Release time:
Sep 28,2018
Causes:
1. Infection of small intestinal coccidia
Infection of small intestinal coccidia is one of the main causes of this disease. Small intestinal coccidia is mainly parasitic in intestinal mucosal epithelial cells. When it grows and multiplies in large quantities, it will inevitably lead to intestinal mucosal thickening, edema, severe shedding and bleeding, which will almost make the feed unable to be completely digested and absorbed. At the same time, the absorption of water is also significantly reduced. Although chickens drink a lot of water, it will also cause dehydration, so the feces discharged by the affected chickens are very thin and shapeless, contains feed that has not been digested.
2. Bacterial infections
Bacteria can cause enteritis, but also one of the causes of intestinal toxin syndrome in broilers: such as Salmonella, gas-producing Clostridium, etc., through the stimulation of the destruction of intestinal mucosa, while causing inflammation to speed up intestinal peristalsis, excessive excretion of digestive juice, feed through the digestive tract to shorten the time, resulting in indigestion.
3. Virus infection
Viruses are also one of the causes of enterotoxic syndrome; for example, reovirus causes enteritis, which impairs the absorption function of the intestine.
4, the intestinal acid-base balance disorders
Due to the season, feed, pathogenic microorganisms and other reasons caused by intestinal flora imbalance, produce a large amount of lactic acid, so that the intestinal PH value is seriously reduced, the intestinal environment changes, beneficial bacteria reduce the proliferation of harmful bacteria, and because the intestinal tract is in an anaerobic environment, Clostridium welchii, intestinal Clostridium and other anaerobic bacteria will multiply, harmful bacteria and coccidia coordinate with each other to strengthen the pathogenicity. This will cause the reduction of beneficial bacteria, and a large number of harmful bacteria growth and reproduction, especially Escherichia coli, Salmonella can increase the pathogenicity. The increase of toxins secreted by the flora stimulates the intestinal mucosa to accelerate intestinal peristalsis, increase the excretion of digestive juice, shorten the time for feed to pass through the intestinal tract, indigestion, and undigested feed is excreted together with the shedding mucosa, forming characteristic tomato-like or fish-like feces.
5, a large amount of electrolyte loss
Due to the large growth and reproduction of coccidia and harmful bacteria, indigestion and intestinal absorption disorders are caused, which reduces electrolyte absorption. At the same time, due to the rapid rupture and disintegration of a large number of intestinal mucosal cells, a large amount of electrolytes are lost, and physiological and biochemical disorders appear, especially the large amount of potassium ions The loss will lead to excessive enhancement of the excitability of the heart, which is also one of the main reasons for the obvious increase of sudden death in broiler.
6. Self-poisoning
In the process of onset, a large number of intestinal epithelial cells rupture, under the action of bacteria, corruption and decomposition occur, and the shedding intestinal mucosa, dead worms, etc. ferment and decompose in the body to produce a large number of toxic substances. At the same time, the toxins secreted by the abnormal intestinal flora will be absorbed by the body and self-poisoning will occur, resulting in symptoms such as excitement, screaming, paralysis and failure and death.
7, drug poisoning
Long-term medication, so that the drug damage to the intestinal mucosa, causing enteritis.
Prevention and control measures:
1. Strengthen feeding management, change bedding frequently, reduce feeding density, reduce the stimulation of various stress factors and prevent the occurrence of complications.
2. Keep the chicken house clean and hygienic, especially the feeding trough and drinking fountain should be disinfected regularly. Keep the chicken house well ventilated and the air fresh. The light intensity, time, temperature and humidity shall meet the technical requirements of scientific management.
3. Feed: Mix mildew-removal agent into the feed for a long time to prevent mildew of the feed, and prohibit the use of moldy feed. Scientific added feed protein and vitamins.
4, the rational use of drug prevention, give the right amount of vitamins, cod liver oil and other nutritional products, contribute to the growth and development of chickens, enhance disease resistance.
