Pheasants tend to be hardy birds. Their lifespan averages 15 years up to 25 years. However, they are prone to poultry diseases, such Botulism, Coccidiosis, owl typhoid, erysipelas, fowl cholera, avian tuberculosis, navel ill, crooked toes (young birds), Newcastle disease .eye infections and worms. Regular treatment for worms is recommended. Parasite Control. Proper vitamin and mineral supplementation will build up their resistance and make them less susceptible to these problems. ..

Tip: Hiding medication in their favorite foods is a stress-free, convenient way to administer medicine.

Avian botulism is a paralytic disease caused by ingestion of a toxin produced by the bacteria, Clostridium botulinum. This bacteria is widespread in soil and requires warm temperatures, a protein source and an anaerobic (no oxygen) environment in order to become active and produce toxin. Decomposing vegetation and invertebrates combined with warm temperatures can provide ideal conditions for the botulism bacteria to activate and produce toxin. There are several types of toxin produced by strains of this bacteria with birds being most commonly affected by type C and to a lesser extent type E.
Birds either ingest the toxin directly or may eat invertebrates (e.g. chironomids, fly larvae) containing the toxin. Invertebrates are not affected by the toxin and store it in their body. A cycle develops in a botulism outbreak when fly larvae (maggots), feed on animal carcasses and ingest toxin. Ducks that consume toxin-laden maggots can develop botulism after eating as few as 3 or 4 maggots.
Susceptible Species:
All domestic poultry: fowls, turkeys, water fowl, pheasants and also most wild birds are susceptible. Carrion-eating birds can withstand large doses of the toxin without showing any symptoms.
Botulism occurs sporadically in poultry raised under conditions where hygiene is poor and where birds have access to rotting carcasses or other contaminated or decaying material. It also occurs occasionally in wild birds particularly if they are feeding in stagnant water holes. Botulism is usually more common in the warmer months.
Clinical Signs/Field Signs
Healthy birds, affected birds, and dead birds in various stages of decay are commonly found in the same area. The toxin affects the nervous system by preventing impulse transmission to muscles which results in flaccid paralysis. Consequently, birds are unable to use their wings and legs normally or control the third eyelid, neck muscles, and other muscles. Birds with paralyzed neck muscles cannot hold their heads up and often drown. Death can also result from water deprivation, electrolyte imbalance, respiratory failure, or predation.

Diagnosis
Diagnosis of botulism is based on demonstration of the toxin in serum from sick birds, or tissue samples from dead birds such as clotted heart blood, stomach contents, or liver.
Treatment / Recovery:
Under favorable environmental conditions - access to clean water, fair weather conditions and no predation - birds can recover from low doses of the toxin. Birds that do recover from avian botulism do not show any increased tolerance for the poison and are not resistant to subsequent exposures. There is some evidence that birds may be protected for short periods of time with a vaccine.
Birds which live through 48 hours of illness usually recover. The following cause of action is recommended:
- Sick birds should be isolated and provided with food and water.
- Supportive therapy with antibiotics and vitamins has been helpful in some cases.
- If possible, remove the source of the toxin. Keep birds away from suspect sources.
- Remove dead birds, supply clean feed and water, clean up around stagnant pools and ensure that all feed is fed in containers and not on the ground.
- The toxin is also found in maggots and litter beetles so these must also be controlled.
Coccidiosis
Coccidiosis is the most common disease of domestic pheasants. It generally causes a bloody tinge to the birds' droppings, and death results if the disease is not treated promptly. Coccidiosis can be kept in control by any of the sulfa family of drugs. A veterinarian should be contacted to determine the best method of treatment and dosage.
- Dust-bathing
- Dusting with pyrethrum-based louse powder
- Systemic insecticide or growth regulator
- Environmental insecticide
Feet Problems:
- Hereditary: bent toes
- Bacterial: bumble foot
- Parasitic: scaly leg
- Crooked Toes
