Pig-and-chicken circular farming model boosts feeding efficiency
The new technology of efficient circular pig-and-chicken farming is a practical technique particularly suited to rural farmers. The method is as follows: ferment chicken manure by the lactic acid method to feed pigs. There are many ways to feed pigs with chicken manure, such as drying it, feeding it fresh, and conventional fermentation, but the lactic acid fermentation of chicken manure is best. This is because this method can turn chicken manure into a high-quality pig feed with good palatability. The fermentation method is: first dry the chicken manure to 70% dryness, then mix an appropriate amount of lactic acid bacteria and 10 kg of wheat bran or rice bran into every 100 kg of chicken manure, put it into non-toxic plastic bags or other containers for sealed fermentation for about 10 days, until a wine-like aroma can be smelled. When feeding pigs, it is best not to mix more than 40% into the feed, and in the feed of sows, especially pregnant sows, it must not exceed 20%; use pig manure fermented to breed insects to feed chickens. Collect and pile up the fresh pig manure every day, about 500 kg per pile, spread it out and dry it to 70% dryness, then add 20% soil and 3% bran or rice bran, mix well, pile it up and seal the manure pile tightly with plastic film for about 7 days, dig a deep pit in flat ground, then spread the fermented pig manure evenly in the pit to a thickness of about 30-40 cm, cover it with green grass or straw curtains or gunny sacks and keep it moist, and prevent water from entering on rainy days. Generally, in about 20 days, maggots, insects and @#@254@#@ etc. will appear, and the insects produced from the manure of one pig can generally feed about 20 chickens.
