Diagnosis and treatment of chicken enterotoxin syndrome

1. The main manifestation of chicken enterotoxic syndrome. Decreased feed intake, slow weight gain or weight loss. Feces thinning, not shaped, feces with undigested feed, the color becomes light yellow, yellow-white or fish intestine-like feces, carrot-like feces. There was a significant increase in sudden death before dawn or agitation and then paralysis, exhaustion and death. Most of them occurred at the age of 40 days.

It is common in broiler flocks whether raised on the ground or on the Internet, resulting in huge hidden economic losses, which are often ignored by breeders and veterinary workers. The chickens with excessive density, excessive humidity and poor ventilation are common, the symptoms are more serious, and the therapeutic effect is poor. The higher the content of protein, energy and vitamins in the feed, the more likely it is to develop enteric toxic syndrome.

The disease can also occur in laying hens. Most of them occur just or before the opening of production. Chickens with enterotoxic syndrome often have respiratory syndrome. After the cure of enterotoxic syndrome, the symptoms of respiratory syndrome will also be alleviated or self-cured.

The disease is often misdiagnosed as general dyspepsia or intestinal coccidiosis, but there is no obvious effect with all anti-coccidiosis drugs.

two。 The main pathological changes of chicken enterotoxic syndrome. The intestinal mucosa is thickened and the mucosa is easy to fall off. There are bleeding spots and necrotic foci on the intestinal mucosa. The intestinal wall becomes thinner, the intestinal content is less, and there is undigested feed. The contents of the intestines are like fish intestines, carrots or persimmons.

3. The cause of chicken enterotoxic syndrome. Infection of small intestinal coccidia; large number of harmful bacteria in the intestinal tract; changes in the intestinal environment; massive loss of electrolytes; effects of protein, energy and vitamins in feed; overuse of anticoccidial drugs and antibiotics; autopoisoning.

4. The therapeutic effect of Provet. Each bag of Previte is 120 kg of water, drinking water for 12 hours a day. After 1 day of use, the feces thickened and the color became darker; after 2 days of use, the food intake increased significantly, the weight gain accelerated, and then recovered in 2 days.

5. Provette is not used to the situation. Diarrhea caused by feed mildew; diarrhea caused by high salt content in feed; physiological diarrhea caused by increased drinking water in hot and humid seasons; sudden binge drinking due to water shortage for a long time

Diarrhea caused by; diarrhea caused by other infectious diseases.
