Dead pigs can be a source of continuing problems. They attract birds, rats and mice and are a breeding ground for flies. Vehicles collecting them pose a serious threat of disease to your herd.

There are five options for the disposal of dead pigs:

1. A self digestion pit dug into the ground and lined with concrete rings. This will cope with pigs up to 50kg. This is only of use in ground with a low water table and in temperate climates.
2. Composting in a deep straw manure heap or using other materials. Pigs will decompose totally within three weeks provided they are placed into the centre of the manure heap and buried at a minimum depth of 1.2m. This is only of value in temperate climates. Make sure there is no access for foxes and other animals. This method can be used for pigs up to 150kg weight.
3. Burial. This will depend on the water table and local restrictions.
4. Incineration on the farm.
5. Removal by a licensed person for incineration or disposal elsewhere. (N.B. This is the only option allowed in some countries).

Care needs to be taken for disease security at the collection site of dead animals. It should be out of the vicinity of the farm and at least 200m away; 400m if live pigs are involved. There should be an entry to the collecting area on the farm side and an exit on the opposite side for collection by the disposing lorry. An example of a reception area is shown in Fig.3-9. There are many variations of design. In some countries the design is stipulated by the authorities.
