Necrotic Enteritis, NE. This is a very common bacterial disease found in the field. This is a very popular disease in commercial chickens, layers or boilers. This disease causes huge economic losses, either due to increased mortality or from poor production performance.

It is a disease of the gastrointestinal tract, Clostridium perfringens infection of the poultry or chicken intestines. The bacteria cause necrotic enteritis in chickens and sudden increase in mortality. However, birds with depression, ruffled feathers, and diarrhoea may also be seen.  The clinical illness is usually very short, and often the only signs are a severe depression followed quickly by a sudden increase in flock mortality caused by an acute enterotoxemia.

necrotic enteritis, small intestine lesions

The gross lesions are primarily found in the small intestine (jejunum/ileum), which may be ballooned, friable, and contain a foul-smelling, brown fluid. In this picture looks a severe lesion in the intestine. The process of occurrence of such lesions has been going on for a long time, but clinical symptoms look just a few days. We will see chickens die abruptly, maybe clinical symptoms can not be observed before.

In severe conditions, we can observe diarrhoea, even blood in the faeces. This condition is often misdiagnosed with coccidiosis. However, coccidiosis does not cause this severe condition in adult chickens.

This disease can cause a decrease in egg production or interfere with growth in broiler chickens, but in some cases with severe intestine the chicken is still able to survive and produce eggs, to be found chickens died suddenly, or the chicken does not produce eggs due to additional infection by other bacteria.

necrotic enteritis and complex infection

In the picture below, a medium lesion appears in the intestine. In these conditions we have not seen clinical symptoms in chickens, chicken manure form still looks normal. However, a few days later we could get chickens died suddenly, with pathological lesions in the colon that is more severe, perhaps with some clinical symptoms or without clinical symptoms seen before.

Unlike other infectious diseases, the chicken mortality pattern appears sporadic. In a chicken flock, or in a chicken house that has thousands of chickens, the disease has developed with varying degrees of severity. Sporadic. Chickens suffering from severe illness will die.

necrotic enteritis, the spread of disease.

The most important factor in the emergence of this disease is a significant change in the intestinal environment conditions. Changes in chicken feed or poor feed raw materials are the most common factor in this case. Treatment is done with the use of antibiotics, but if the cause of the disease is not diagnosed with certainty, then the disease will occur again after treatment is completed. Usually, in the field, the effective control for this disease is, evaluating the quality of feed ingredients and the use of antibiotics if high mortality is observed. Some breeders use probiotics and acidifiers in chicken feed for control.
