How do I keep my dairy and poultry farm biosecure to prevent disease spread?

Biosecurity is just keeping disease out and stopping it spreading, and a few simple habits prevent most outbreaks. Control entry by limiting visitors and vehicles, using a footbath or disinfectant at the gate and shed, and not letting people move between sick and healthy animals without cleaning up. Quarantine any newly bought animals or birds away from the main herd or flock before mixing them, since market purchases are a common way disease enters. Keep feed and water clean and protected from rodents, wild birds and dung contamination, and remove and dispose of dead animals properly rather than leaving them around. Clean and disinfect sheds and equipment between batches, and follow the vaccination schedule from your veterinarian. These low cost steps usually save far more than they cost in lost animals and treatment.
