- Emaciated (abnormally thin or weak)
- In early stages some chickens may appear depressed
- Chickens die for no apparent reason
- High death rate
Birds Most Susceptible to Necrotic Enteritis Are:
Necrotic Enteritis is a disease stemming from the domestication of birds and is not likely to threaten wild birds. Birds most susceptible are:
- Rapidly growing young birds.
- Chickens and turkeys 2-12 weeks of age are most susceptible.
- Over crowded flocks.
- Immuno-suppressed flocks.
- Flocks kept in unsanitary conditions.
- Most commonly affects broiler birds, roasters, and turkeys.
- Ulcerative enteritis commonly effects pullets and quail.
Synonyms of Necrotic Enteritis
Other synonyms or names for Necrotic Enteritis are enterotoxemia and rot gut.
Causes of Necrotic Enteritis
Necrotic Enteritis grows inside the intestinal tract and is contracted when a chicken ingests bacteria from:
- Infected soil
- Infected feces
- Other infected materials
Treatment for Necrotic Enteritis in Poultry
- Isolate infected birds
- Bacitracin (most commonly used)
- Neomycin
- Tetracycline
- Penicillin

How to Prevent Necrotic Enteritis in Poultry
Proper sanitation, waste disposal, husbandry, and management can significantly reduce the chances of your chickens contracting the clostridia bacteria in necrotic enteritis.
- Keep your chicken coop clean and dry
- Scoop the feces out of the litter if you use litter. Change scooped litter completely at least once per month.
- Frequently turn the soil or move birds to a different area.
- If you find a sick bird-isolate it from the flock, then clean and sanitize everything in and around the coop so other birds do not get infected.
- Keep clean fresh water available at all times.
- Make sure feces do not come in contact with feed or water.
- Keep birds in a very large fenced run which does not let wild birds in.
- Move hen house, coop and run to fresh ground every six weeks.

Chickens may get Coccidiosis at the same time as Necrotic Enteritis Necrotic Enteritis and Coccidiosis both have similar symptoms and often occur together so you may wish to also see information about coccidiosis here: See Cecal Coccidiosis-Signs, Symptoms & Treatments |
Oregano for Necrotic Enteritis Prevention Healthy alternatives to Antibiotic growth promoters commonly used on grower farms for broiler hens. Antibiotic growth promoters can produce antibiotic immunity in humans, as a result, new laws and regulations are being put in place to regulate poultry and livestock feed. Many farmers depend on these antibiotic growth promoters to keep their flock healthy and to make them gain weight faster but you may be surprised to find out that studies show oregano essential oil, carvacrol, and thymol can do the same things as them..but better...

Updates: Necrotic Enteritis in Chickens Study 2022
Consumers recent push to stop the commercial poultry broiler industry from using antibiotics due to the fact that using antibiotics can actually cause people who eat these commercial broilers to develop a resistance to antibiotics they may need when they are given them by their physicians. As a result, the commercial broiler industry is suffering heavy financial losses due to the birds getting sick with illnesses such as Necrotic enteritis (NE) type A strains and C strains.
"Necrotic enteritis (NE) is a Clostridium perfringens-induced disease of poultry and is caused by Clostridium perfringens type A strains and type C strains. Clinical and subclinical NE infections occur when C. perfringens colonizes and proliferates in the small intestine to produce extracellular toxins that damage the intestinal wall. Consumer concern over antibiotic resistance has increased pressure on poultry producers to increase the number of flocks raised without antibiotics. This recent push to remove antibiotics from poultry production has led to an increase in the incidence of NE in the poultry industry" .
The poultry industry is in process of finding other ways of controlling pathogenic bacteria (bacteria which causes disease), Necrotic enteritis in particular due to the sudden high death rates. Bacteria contamination can occur due to contaminated surfaces, equipment, water, and animal microbiota (gut). In this study researchers tested birds who were induced with the bacteria and had a control group that was not induced. There was a "total of 192 one-day-old male Cobb500 broiler chicks obtained from a commercial hatchery were raised in Petersime battery cages for 28 days at the Southern Poultry Research facility (Athens, GA, USA). Chicks were weighed by pen and then randomly distributed to one of two treatment groups: unchallenged and challenged birds, in a completely randomized design. A cage was treated as a replicate. Each treatment was replicated in eight cages (n = 8) of twelve chicks per cage. Birds were raised under standard management practices and had ad libitum access to a diet of mash feed and water. Feed intake, body weight, and mortality were measured weekly from the day of hatch. Mortality was recorded. Average feed intake and body weight gain (BWG) were corrected for mortality when calculating the feed conversion ratio (FCR) for each pen...Birds in the challenge group were orally gavaged with 5 × 103 oocysts of E. maxima on d 14 post-hatch and 1 × 108 CFU/bird of a netB positive strain of C. perfringens on d 19, 20, and 21 post-hatch. On day 21 post-hatch, three birds per cage were randomly selected and scored for NE lesions on a scale of 0–3. The 0–3 scoring scale was as follows: 0 is normal, 1 shows slight mucus covering the small intestine, 2 has a necrotic small intestinal mucosa and 3 shows sloughed cells and blood in the small intestinal mucosa and contents....
In conclusion, the NE challenge caused a shift in the microbiota and cecal tonsil transcription at 6 days post-Eimeria infection. Campylobacter was upregulated in the ceca of challenged birds. Unexpectedly, although Clostridium was numerically higher in the ceca of challenged birds, this was not statistically significant, which may be due to the time of sample collection. Most of the downregulated genes in the challenged birds are related to lipid metabolism, whereas the upregulated genes were related to immune response. Oocyst shedding and gut permeability were higher in challenged birds, which also showed decreased performance. (Akerele G, Al Hakeem WG, Lourenco J, Selvaraj RK. July, 27, 2022).
The poultry industry have ongoing research and studies to find a way to control and improve the chickens overall intestinal gut health but recent studies have indicated that Oocyst shedding were higher in the tested birds who were induced with the bacteria, Studies have not been successful in finding a cure for preventing the intestinal bacteria which causes Oocysts to multiply and spread the bacteria. Oocysts can be shed from the chickens feces (poop) and spread to others in the flock who come in contact with contaminated feces, feed, water, bedding, shoes, clothing, equipment used in production, vehicle tires, coop, run etc. Necrotic Enteritis continues to be a problem due to the fact that the birds are not being treated with antibiotics because of the risk to humans of developing antibiotic resistance from eating meat from birds and animals who have been treated with antibiotics. However, if you have chickens and are not planning to eat your birds or their eggs you could prevent Necrotic enteritis with antibiotics. Many are using probiotics rather than antibiotics to improve their chickens gut health.
