Farmers can use pig manure to produce biogas, improve their soil, grow
better crops, and spend less on industrial fertilisers, which are usually
expensive. Manure from pigs can also be used for rearing insect larvae,
which are used as chicken, fish and pig protein and energy (fat) sources.
An example of the insect larvae used in animal feed is the black soldier
fly larvae.
