The wheat middling is then added in and mixed. The mixture is then pressed out in a mould eg. The hard block is offered to healthy animals with grass and other feeds. Forage must always be available. While waste from intensive livestock production can have a negative impact on the environment it can be a valuable farm resource.
Manure is collected and recycled on to crops.
In the plants, the animals' manure is digested by bacteria under anaerobic conditions producing methane and other gases. This is used for cooking but, if in sufficient supply, may also be used for lighting on the farm and for the running of engines. The treated effluent is a better quality manure without the characteristic odours and is less harmful to the environment. The effluent also conserves water for fertilizing and irrigation in the dry season. This is expected to continue.
