Common Diseases Of Pigs

Disease Prevention & Control
- Housing and ventilation
The house should facilitate proper cleaning, disinfection and maintenance of sanitary conditions. Good ventilation is essential in disease control and air must move through the building such that foul air is replaced with fresh air.
- Proper manure disposal
Disease causing agents may be contained in urine, feces, exhalation and nose and mouth discharges. These may act as media for growth of disease causing agents. Excrement must be removed frequently from the immediate surroundings.
Manure may be heaped so that the heat generated kills the parasites and microbes. It is recommended that manure be kept in a covered concrete pit and the manure in the put sprayed with insecticides to inhibit development of disease causing organisms and flies.
- Pigs kept on pasture should be rotated in the paddocks
Rotation on pasture will disrupt the life cycle of many disease causing agents as these agents are sometimes specific for certain hosts. Pastures may be rotated between different species.
- Provide suitable feed and water containers
- Isolate new animals
- Dispose of dead pigs properly
- Use of disinfectants
- Hire a veterinarian doctor
