2. Add 300 kg of feed raw materials such as 1000 kg of wheat bran, soybean meal, corn kernels, rapeseed cake, cottonseed cake, chicken manure, pig manure, duck manure, etc. and mix them evenly to make the humidity reach about 40%.
3.30-40% of coarse materials (rice bran, cassava residue, peanut shell powder residue, bean residue, straw, etc.). ) can be added in the process of fermenting feed to reduce feed cost. Then the fermented feed is stacked or sealed in a fermentor or other containers, and the fermentation time is appropriately adjusted according to the external temperature, about 5 days in winter and spring, and 2 days in summer and autumn, and it is proved that the fermentation is successful when a sour smell of fermentation is smelled.
4. After fermentation, pack in woven bags.
5. Add 2-4% premix or 6% fresh pine needle powder and other trace elements and minerals when feeding.
