Fermentation: 50% corn (2469, 0.00, 0.00%) powder, 50% cottonseed meal or rapeseed meal (2579, -12.00, -0.46%), 0.5% salt, mix into the chicken manure Mixing in the mixer or stirring on the ground, the amount of mixture adjusted according to the moisture content of fresh chicken manure, adjust the moisture to 45% to 50%. That is, by clasping your hands, you can group them and spread them with a touch. The diameter of the raw material particles after mixing is not more than 1 cm. The mixed fermented material is piled into a trapezoidal shape with a height of 60 cm and a width of 100 cm. The length is not limited. When it is piled, it should not be pressed, and it should be kept loose. Above covered breathable insulation materials, such as straw, linen and so on. The use of wild feces in chicken feces to produce heat, the temperature up to 55 ~ 65 °C, can kill most pathogenic bacteria and parasite eggs, and can use the non-protein nitrogen in chicken manure into bacterial protein, but also Can produce some useful other ingredients, such as enzymes, B vitamins, antibiotics and so on. If the temperature drops during the fermentation, it means that the oxygen has been exhausted. Therefore, aeration and oxygenation should be performed after 36 hours of accumulation, and the surface and bottom layer should be turned to the middle to ensure uniform fermentation. After 24 to 36 hours of turning, the fermented material can be exposed to sunlight and dried. After the dried chicken manure fermentation material is crushed, impurities such as chicken feathers are screened out and bagged for use. The chicken manure after fermentation has a clear fragrance, and most cattle and sheep do not refuse to eat.
1. Mix with energy feed and add some flavoring agent: chicken manure has higher crude protein content but lower available energy value. It can be mixed with corn, sub-powder and other energy feeds to adjust the ratio of energy to nitrogen and promote the development of rumen microbial community. . It is helpful to accelerate the adaptation of cattle and sheep to chicken manure. It can be considered to use 40% to 50% chicken manure mixed with 50% to 60% corn meal, and add 1% salt as the concentrate of cattle and sheep. Fruity or grainy flavors can mask the bad smell of chicken droppings and enhance palatability.
2. Production of pellet feed: The pellet feed can be used to reduce the dust of the chicken manure. In addition, the high-temperature, high-pressure granulation process is conducive to the killing of harmful bacteria and parasite eggs, and has the effect of flavoring and improving the flavor.
