VIRAL DISEASES
CONTENT
- Foot and mouth disease
- Rinderpest diseases
- Newcastle disease
- Fowl pox
- Gumburo disease
| VIRAL DISEASE | ANIMAL AFFECTED | MODE OF TRANSMISSION | SYMPTOMS | CONTROL/PREVENTION |
| FOOT AND MOUTH DISEASE | Cattle, Sheep and Goat | contact, air-borne, droplets of saliva, infected materials like urine, faeces. | Formation of blisters (skin vesicle filled with serum, watery animal fluid) on the skin, between and around the hooves, inflammation of teats and udder, salivation, loss of weight. | Isolation of infected animals, burning or burying contaminated materials, timely vaccination. |
| RINDERPEST DISEASE | Cattle, Sheep and Goat | By contact, contaminated feed and water | High fever, weakness, difficult breathing, blood stained diarrhoea, high mortality, loss of appetite. | Timely vaccination, isolation of infected animals, restriction of infected animal movement within the farm. |
| NEWCASTLE DISEASE | Domestic fowl, Turkey, Goose, Ducks and Guinea fowl | Through contaminated feed, water and litter | Sneezing, nasal discharge and difficult breathing. Lack of appetite and diarrhea, Paralysis, somersaulting, twisting of neck, cycling movement | Vaccination, good sanitation, disinfection of poultry building. |
| FOWL POX | Fowl | Through contaminated feeds, water and litter materials | Sores on the combs and wattles | Isolate the infected birds, practice good sanitation measures, apply iodine on the affected parts, adopt routine vaccination |
| GUMBURO DISEASE | Birds | Through faecal, contaminated feeds, water and litter. | Swelling of liver, spleen and kidney. The birds appear dull and sleepy. | Isolate infected birds to maintain good sanitation measure, adopt routine vaccination. |
BACTERIAL DISEASES
CONTENT
- Anthrax
- Brucellosis
- Tuberculosis
- Pullorum Disease
- Fowl Typhoid
- Fowl Cholera
| BACTERIAL DISEASE | ANIMAL AFFECTED | MODE OF TRANSMISSION | SYMPTOMS | CONTROL/PREVENTION |
| ANTHRAX Bacillus anthraxis | Cattle, Sheep, Goat, Pig. | Through contaminated feed, water, equipment and infected animals. | High fever, depression, staggering and sudden death of the animal. | No effective drug for the treatment. Regular vaccination, infected animals should be slaughtered and buried, proper sanitation. |
| BRUCELLOSIS (CONTAGIOUS ABORTION) Brucella abortus | Pigs, Cattle, Sheep and Goat. | Contaminated feed, water, contact with infected animals, contact with infected materials such as shoes etc. | Abortion, inflammation of the womb, diarrhoea and dysentery, paralysis, loss of milk and frequent infertility. | Sick animals should be isolated and badly infected animals should be killed and burried. |
| TUBERCULOSIS Mycobacterium tuberculosis | Cattle, Sheep, Goat, Pigs and poultry birds. | Sputum, droppings, milk of infected Cow, germ inhaled or through mouth during feeding | Constant coughing, loss of weight and appetite, infection of liver and udder in Cows. | No cure of drug. Animal infected should be killed and buried, good sanitation, isolate suspected animals. |
| PULLORUM DISEASE | Poultry | Through contamination of feeds, water and litter | Watery droppings that are usually sticky and greenish – white in colour. | Obtain chicks from sources that are disease free, Isolate infected birds, Maintain good sanitation, Treat the infected birds with appropriate antibiotics. |
| FOWL TYPHOID | Fowl | Through contaminated feed, water and litter materials | Yellowish watery droppings, loss of appetite and ruffled appearance. | Routine vaccination, Maintain good sanitation, Treat the infected birds with appropriate antibiotics |
| FOWL CHOLERA | Fowl | Through contaminated feed, water and litter. | Ruffled appearance, thirst due to dehydration, blood-stained yellowish watery droppings and sudden death. | Isolate infected birds, Maintain good sanitation measures, Practice routine vaccination and treat the infected birds with appropriate antibiotics. |
FUNGAL DISEASES
CONTENT
- Ringworm
- Aspergillosis
| FUNGAL DISEASE | ANIMAL AFFECTED | MODE OF TRANSMISSION | SYMPTOMS | CONTROL/PREVENTION |
| RINGWORM | Cattle Sheep, Goat and Rabbit | Contact with contaminated feeders and water troughs | Lesions (injury, damage, change in texture) in the skin of the animals, irritation of the skin, loss of appetite and weight. | Disinfection of pens and equipment, treat affected parts with sulphur ointment. |
| ASPERGILLOSIS Aspergillus fumigates | Poultry birds, pigs, Cattle | Through contaminated feed (mouldy feed), mouldy litter. | Difficult breathing, respiratory disorder, loss of appetite, irritation of skin, high body temperature, loss of weight. | Regular disinfection of the pen and equipment, avoid use of mouldy feed, practice good sanitation and maintain proper hygiene, spray fungicide from time to time to kill fungi spores. |
PROTOZOAN DISEASES
CONTENT
- Trypanosomiasis
- Coccidiosis
- Red water fever (Piroplasmosis)
| PROTOZOAN DISEASE | ANIMAL AFFECTED | MODE OF TRANSMISSION | SYMPTOMS | CONTROL/PREVENTION |
| TRYPANOSOMIASIS | Cattle, Sheep and Goat | Spread by the blood sucking Tse-tse fly which sucks blood from an infected animal and transmit the pathogen to healthy animal. | Rise in body temperature, dullness in appearance, constant sleeping. | Clearing of bush around farm in order to remove the fly’s habitat, spraying with insecticides to kill vector, treatment with drugs such as trypanosomide and antimosan. |
| COCCIDIOSIS Eimera sp | Domestic fowl, duck, goose, turkey, guinea fowl and rabbit | It is spread through faeces, litter, feed, water and contaminated soils. | Dropping wings, loss of appetite, blood stained diarrhoea, emaciation, high mortality, loss of hair/ acopecia (in rabbit) | Proper sanitation, avoid wet litters and feed, change of litter used and general disinfection, use suitable drugs such as amprolium and nitrofurazone in water, treat with coccidiostats. |
| RED WATER FEVER (PIROPLASMOSIS) Babesia sp | Cattle, Sheep, Goat and Pig | It is transmitted through the bite of vector called Blue tick. | Rise in body temperature, loss of appetite, diarrhoea, pale red colour of urine, emaciation and death. | Spray with insecticides to kill vector of disease (blue tick), injection of drugs such as Trypan Blue, Babesan or Phenamidine. |
