Ecological pig-culturing method

Abstract

The present invention discloses an ecological pig-raising method. It is characterized by that the Chinese pennisetum whose growth is quick and yield is high can be planted around the pig farm, in the lower side of said pig farm a methane-generating tank is built up. The pig's fecal sewage can be flowed into said methane-generating tank, fermented and can be made into the organic fertilizer for promoting growth of Chinese pennisetum. The harvested Chinese pennisetum can be undergone the processes of pulping and mixing with concentrate and can be used for raising pigs, and said harvested Chinese pennisetum also can be mixed with the Chinese medicinal materials of astragalus root, lonicera flower, scutellaria root and licorice root, etc. and made into a natural plant source immunity-regulating agent for raising immunity of pigs.

Description

technical field [0001] The invention relates to an ecological pig raising method, in particular to an ecological pig raising method using pennisetum as a compound diet. Background technique [0002] With the rapid development of my country's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. If a large amount of pig manure and urine wastewater is not treated properly, the water quality will be affected. Because pig manure and urine contain a large amount of Organic matter and organisms will consume dissolved oxygen in water when they decompose, and then destroy the ecological balance. For example, when the water source of tap water is polluted by pig feces and urine wastewater, the water will have a bad smell, which will affect people's drinking; second, it will hinder environmental sanitation, Because pig manure and urine will emit a pungent odor, and it is easy to breed mosquitoes and flies, ...
