In recent years, the edible fungi industry has developed rapidly, and its by-products, waste mushroom materials, are also increasing. Farmers can use these waste materials to feed fattening pigs, which is better than feeding rice bran. It can achieve the feeding effect of corn, and can reduce costs and increase economic efficiency.
Edible fungus has a strong ability to decompose fiber, therefore, the crude fiber in the waste of cultivated edible fungi is reduced by 50% and the lignin is reduced by 30%. Because the waste contains a large amount of bacterial proteins, the crude protein content increased from 2% to 6%-7%, and the fat content also increased by about 1 times.
According to the analysis, the use of rice straw, wheat straw, corn cobs and other fiber materials to cultivate Pleurotus ostreatus and Pleurotus ostreatus can produce 80 kg of fresh mushrooms per 100 kg of raw materials, and 60 kg of nutrient-rich bacteria can be obtained. The strains contained crude protein 6.15%-10.92%, crude fat 0.2%-1.4%, crude fiber 3.25%-11.63%, crude protein content slightly higher than fine rice bran, and crude fiber content was much lower ( In the fine rice bran, crude protein was 9.4%, crude fat 15.0%, crude fiber 11.0%), which was beneficial to the absorption of zinc, iron, calcium, phosphorus and other elements, especially zinc absorption, can enhance the immune function of pigs and improve The resistance to diseases improves the digestion and metabolism of nutrients by pigs and promotes growth and development. With 1/3 of bacillary dysentery and other feed with pigs, the average daily gain of 780 grams or more than the daily feed rate with other feeds to feed more than 50% higher, saving food 40%, cost reduction of 50%, lean ratio than feeding Corn is about 5% higher. The initial addition of bacillary dysentery should be from less to more, and gradually increase from 10% to 30% after about a week of adaptation.
The specific method is to put waste residue in the green feed beater and then mix it with other feeds; it can also be directly mixed with other feeds without processing. The sun-dried fungus feed can be stored in whole pieces and then crushed when used. For the remaining waste materials should be dug out the part of infected bacteria, dried, put it in a cool dry place, do not rain, to prevent mildew.
