Livestock as pets
Depending on the size of your property you may or may not be able to have livestock as pets. You will need to check with your local Council to see if such pets are permitted on your property, how many you can have and the restrictions in place to limit the disturbance of the animal to the neighbourhood. If your animal becomes a disturbance your Council may direct you to remove them from the property.
Generally, all livestock kept as pets will need to have easy access to food and water, and be able to move freely around their enclosure. Care should be taken to protect animals from the weather and disease.
This website has numerous policy documents and Codes of Practice surrounding livestock. These are largely aimed at production farms but the basic principles behind them can be interpreted for the keeping of livestock in backyards or on hobby farms, if permitted by your Council.
The Prevention of Cruelty to Animals Act 1986 protects the welfare of all animals, including livestock.
