There is a disease commonly found in chicken flocks characterized by diarrhea, feces containing undigested feed or persimmon-red droppings; decreased feed intake, slow growth or weight loss; and post-mortem findings of tomato-like contents in the intestines. The prevalence of this disease is currently on the rise. Although the mortality rate is not high, the hidden economic losses it causes are enormous. According to investigations and studies by relevant scholars, this disease is a syndrome caused by multiple etiological factors - "chicken intestinal toxin syndrome."
Causes of chicken intestinal toxin syndrome
Infection by small intestinal coccidia: Infection by small intestinal coccidia is one of its main causes. Small intestinal coccidia commonly affect chicken flocks at 20-40 days of age, mainly because the number of oocysts in litter and feces increases significantly, leading to severe coccidial infection at this stage.
Concurrent viral infection: Many viral infections can be one of the triggers for intestinal toxin syndrome. For example, reovirus, which causes enteritis that can impair intestinal absorption function. Typical symptoms of chicks infected with reovirus include poor development, stunted growth and diarrhea, among others. In addition, there are adenovirus, coronavirus, etc.
Bacterial infection: During the process of small intestinal coccidial infection, small intestinal coccidia multiply massively in the intestinal mucosal cells, consuming large amounts of oxygen, causing the small intestinal mucosal tissue to produce large amounts of lactic acid, reducing beneficial bacteria and allowing harmful bacteria to multiply massively. In particular, Escherichia coli, Salmonella, Clostridium perfringens and others seize the opportunity to multiply massively. Coccidia and harmful bacteria act synergistically, enhancing pathogenicity.
Massive loss of electrolytes: Coccidia and bacteria grow and multiply rapidly in large numbers, leading to indigestion, impaired intestinal absorption and reduced electrolyte absorption.
Effects of toxins: Exogenous toxins may be present in feed, and may also be present in drinking water and feed by-product ingredients, such as aflatoxin. Endogenous toxins refer to the clinical symptoms that appear during the course of the disease, such as soft legs, lethargy, coma, exhaustion and death.
   In addition, the effects of vitamins, energy and protein in feed: The richer the feed nutrition, the higher the incidence rate and the more severe the symptoms, while lower-quality feed has a relatively lower incidence rate. This is because in the mixed infection of coccidia and bacteria, large amounts of energy, protein and some vitamins promote the massive proliferation of both, aggravating the symptoms.
Epidemiological characteristics of chicken intestinal toxin syndrome
In developed farming areas, whether floor rearing or net rearing, whether broilers or laying hens, this disease is commonly present, and it is more frequently seen in summer and autumn.
Symptoms of chicken intestinal toxin syndrome
The mental state of the chicken flock is still fairly good, but growth is slow and combs are pale. Some sick chickens pass white strip-like or mucous-like feces, the feces contain undigested feed, and the fecal color is slightly yellow. A few chickens are depressed, retract their heads, have head tremors, run around aimlessly, are prone to shrieking, and then become paralyzed. The affected flock shows sporadic deaths, with cull chickens appearing almost every day.
Prevention and treatment of chicken intestinal toxin syndrome
1. Keep the chicken house clean and hygienic, and avoid damp environments.
2. To prevent concurrent infection of colibacillosis and coccidiosis, deworm the chicken flock regularly.
3. When diarrhea symptoms are found in the chicken flock, do not arbitrarily assume it is enteritis and simply use drugs for treating enteritis, so as to avoid causing dysbiosis of the intestinal flora and damaging the intestinal mucosa of sick chickens.
4. Regularly use disinfectants for disinfection with chickens present, or regularly mix disinfectants into the sand that the chicken flock frequently pecks at.
      Classic scheme for prevention and treatment of chicken intestinal toxin syndrome: Zhengchang + Qiujian + Lijunkang + cod liver oil
Morning: Zhengchang (400 jin water/bag) + Qiujian (300 jin water/bag) for concentrated drinking water, once a day, for 3 consecutive days
Afternoon: Lijunkang (300 jin feed/bag), steeped in boiling water for 30 minutes, then mixed into feed for concentrated feeding, for 4—5 consecutive days.
