Animal Housing, Farm Management, and Biosecurity
Animal Housing, Farm Management, and Biosecurity tests site selection, space, ventilation, waste handling and disease prevention. Questions often describe a farm plan and ask what is wrong.
Core rules
- Choose an elevated, well-drained site with good water, all-weather road access and distance from residences and other farms. Place animal sheds downwind of the house and away from water sources.
- Housing must provide dry flooring, adequate space, ventilation without draughts, shade and easy cleaning. Overcrowding raises humidity, ammonia and disease.
- Farm management includes records of feed, milk, reproduction, health and costs; records support culling and breeding decisions.
- Biosecurity has three layers: isolate incoming or sick animals; control visitors, vehicles and rodents; sanitise sheds, equipment, boots and feed stores.
- Manure and dead animals need planned disposal. Footbaths and quarantine pens are useful only if maintained.
Worked example
A proposed dairy site is low-lying, 30 m from a village well and next to a poultry shed. The reasoning rejects it: low land floods, the well risks contamination, and close poultry increases disease spread. A better site is elevated, downwind, farther from the well and separated from other livestock.
Traps
Do not treat vaccination as the whole of biosecurity. Do not site sheds uphill of a drinking-water source. Do not ignore drainage and ammonia. Do not keep visitor records without enforcing entry control.
