Curriculum reference: B8.2.4.1 Understand animal health, disease control and housing requirements. Indicator B8.2.4.1.1: Identify common diseases affecting farm animals and their control. All the exemplars are merged into one set of notes.
1. Why Animal Health Matters
Healthy animals grow fast, give more meat, milk and eggs, and earn more money for the farmer. Sick animals grow slowly, may die and can pass diseases to people.
2. Signs of a Sick Animal
- Loss of appetite and weight loss
- Dull eyes, rough coat or dull feathers
- Fever, coughing or difficult breathing
- Diarrhoea or bloody droppings
- Swollen body parts, sores, limping or staying apart from the others
- Drop in milk or egg production
3. Common Diseases of Farm Animals
| Disease | Animal | Cause | Signs | Control |
|---|---|---|---|---|
| Newcastle disease | Poultry (fowl) | Virus | Coughing, greenish diarrhoea, twisted neck, sudden deaths | Vaccination, hygiene, quarantine |
| Fowl pox | Poultry | Virus | Wart-like sores on the comb and face | Vaccination, control of mosquitoes |
| Coccidiosis | Poultry | Protozoa | Bloody droppings, weakness | Dry clean litter, drugs given by the vet |
| Anthrax | Cattle, sheep, goats | Bacteria | Sudden death, bleeding from natural openings | Vaccination, burn or bury dead animals deeply |
| Foot and mouth disease | Cattle, sheep, goats, pigs | Virus | Blisters on mouth and feet, limping, drooling | Vaccination, quarantine, movement control |
| Trypanosomiasis (nagana) | Cattle | Protozoa spread by tsetse flies | Fever, weakness, weight loss | Control tsetse flies, drugs |
| Worm infestation | All farm animals | Roundworms, tapeworms, liver flukes | Weight loss, pot belly, diarrhoea | Drenching with dewormers, clean pens |
4. Prevention and Control Measures
- Vaccination: giving animals vaccines on time so that they build protection against diseases.
- Hygiene: clean pens, clean drinkers and feeders, and removal of dung.
- Quarantine: keeping new or sick animals apart before they join the flock or herd.
- Good feeding: a balanced diet and clean water make animals strong.
- Control of pests: dip or spray against ticks, lice and flies.
- Regular visits by a veterinary officer and quick treatment of sick animals.
- Burn or bury dead animals properly.
5. Housing Requirements
- Enough space so that animals are not overcrowded.
- Good ventilation and light, with a roof to protect from rain and sun.
- Dry, easy-to-clean floor.
- Safe from thieves and wild animals such as snakes and rats.
- Separate sections for young and sick animals.
- Feeders, drinkers and a good drainage system.
- Built away from the farmer’s house but close enough for easy care.
Remember: Prevention is better than cure. Vaccinate, keep pens clean and quarantine sick animals.
