CoccidiosisInfected birds or chicks become droopy, look unthrifty, and usually have ruffled feathers, pale beaks and shanks. Caecal coccidiosis has bloody droppings. Mortality may be high and sudden.The disease is caused by coccidian, which multiply very rapidly in the intestines. It usually occurs at 8 to 10 weeks of age and normally expresses itself in acute and chronic forms. In the acute type, death occurs in 5 to 7 days. The chronic type does not kill immediately but persists for long.Sulphur drugs are normally used for treatment, use of coccidiostat in feed and always ensuring dry litter are other controls.
Fowl CholeraThe disease spreads very rapidly in a flock. There is yellowish colouration on birds’ droppings, which is followed by yellowish or greenish diarrhoea. Infected birds become droopy, feverish and sleepy. The birds also sit with the head down or turned backwards or rested in feathers about the wing.

The disease is caused by pasteurella avicida, a microorganism that multiplies very rapidly in the blood causing poisoning. Sick birds, wild birds, human, animals or utensils transmit the disease.Birds with acute type should be destroyed and burned. House should be thoroughly cleaned and disinfected. Treatment with recommended sulphur drugs is effective. Ensuring there is no wet litter is important, which provides ideal conditions for coccidian.

New Castle Disease
In chicks, gasping coughing and sneezing is observed and ater nervous systems. Birds may be seen sitting on their back hock joints; others may walk backwards; or in circles; or hind their head between their legs.

In adult birds, external symptoms are more of respiratory nature, plus sudden decrease in egg production. Birds lose appetite and are droopy. If infection is severe, most birds sit on the floor and the roosts.
Egg production declines up to zero in 4 days. When laying resumes, misshapen eggs are produced with rough shells and sometimes bleached shells.

This disease is caused by a virus that infects respiratory and nervous system. In both chicks and old birds mortality varies from 0 to 100% depending on virulence of the organism.
Vaccinate chicks at 3 to 4 weeks of age. Repeat at 16 weeks of age and at the 24th week. Thereafter vaccinate when there is an outbreak in the area.

Fowl Typhoid
Symptoms include dullness, ruffled feathers, paleness of the head drooping comb, loss of appetite and pale orange coloured diarrhoea. Symptoms appear in 3 to 4 day after infection and death occurs in 2 weeks. The disease can be introduced into the flock by infected birds, materials, shoes, litter, etc.

The disease is caused by a microorganism called salomonella gallinarum or shigella gallinarum.
Vaccinate the birds at 7 weeks of age.
Destroy all dead birds by burning.
Do not allow visitors to enter into the poultry unit without being disinfected.
Pullurum Disease
Chicks utter squeaky chirps and appear drowsy and ruffle. Vent is sometimes smeared with faecal discharges. In adult birds no external symptoms are seen. In baby chicks, symptoms are seen in 4 to 10 days with death occurring in 3 weeks.

Pullurum disease is caused by a microorganism called Salomonella Pullurum, which infects the ovary of the hen. The microorganism can also be found in the intestine of chicks. The disease is usually spread by eggs laid by birds carrying the microorganism and chicks hatched from those eggs.

Destroy all confirmed carriers of the disease.
Clean and disinfect all the premises and incubators
Get chicks from hatcheries with good disease control programme.
