Pig chicken circulation feeding technology refers to the use of chicken manure containing certain nutrient substances to replace part of the pig feed after treatment, and at the same time it will be a kind of ecological farming method of fermenting pig manure to chickens. It not only realizes the recycling of resources, but also solves the problem of faecal pollution of the environment. At the same time, it has the characteristics of low cost and easy operation, and can be promoted among farmers.
1. Fermentation of chicken manure by the lactic acid method Fermentation of chicken manure by the lactic acid method can improve the quality and palatability of the chicken manure. The fermentation method is: first dry the chicken manure to 70% dry, and then mix the appropriate amount of lactic acid bacteria per 100 kilogram chicken manure. And 10 kg of wheat bran or rice bran, into a non-toxic plastic bags and other containers for sealed fermentation for about 10 days to be able to smell the wine can be. The proportion of incorporation in the feed should not exceed 40% when feeding pigs, and not more than 20% in sows, especially pregnant sows.
Second, after the fermentation of pig manure, the larvae will be collected and piled on fresh pig manure every day, spread out to dry to 70% dry, and then add 20% of soil, 3% of bran or rice bran and mix well, and use plastic film to dung. Sealed and fermented for 7 days. Dig a deep pit of 50 cm in length on the flat ground, and then spread the well-fermented pig manure in a pit about 30 to 40 cm thick. Cover it with grass or straw curtains and sacks and keep it moist. Drain ditches to prevent rain from entering the water. Generally about 20 days can give birth to maggots, worms and cockroaches. The worms produced by the feces produced by one pig can generally feed about 20 chickens.
Third, do a good job in fermentation and environmental management Because the feces will be processed during the fermentation process will pollute the surrounding ground, and emit odors, summer and autumn will also breed a large number of mosquitoes, so the treatment field must be far away from the living area, and the farm must maintain a certain Distance, in particular, should be far away from living and producing water sources, and prevent the destruction of wild beasts such as rats and minimize pollution to the environment.
IV. Controlling the percentage of chicken feces added in the proportion of pig feed should be controlled within 40%, and the proportion in sow feed should not exceed 20%. Pig manure is fed to chickens and the scale of breeding is determined by 1:20.
