Problems solved by technology
At present, among the total amount of domestic straw, about 20% are directly used as living fuel, about 15% are used as feed, about 2% are used as industrial raw materials, and more than 60% of the remaining straw is used as low-grade fertilizer to return to the field, It is discarded or burned directly, which causes a great waste of resources and environmental pollution
In order to solve this problem, people have tried to improve the utilization value of straw with physical and chemical methods, but because these two methods have not been able to obtain satisfactory results
At present, there are no relevant reports on the use of bio-fermented straw for livestock and poultry animal feed

Abstract
The invention relates to a formula of livestock-poultry grain-saving feed using biological fermentation straw to partially replace corn. In the formula, the biological fermentation straw partially replaces the corn in the common livestock-poultry feed, and the biological fermentation straw accounts for 5 to 20 percent of the total weight of the common livestock-poultry feed. In particular, the livestock-poultry feed consists of the following ingredients in percentage by weight: 45 to 65 percent of corn, 20 to 35 percent of bean pulp, 4 to 15 percent of biological fermentation straw, 1 to 3 percent of fish meal, 3 to 8 percent of bean oil, 0.5 to 2 percent of rock flour, 1 to 2 percent of calcium hydrogen phosphate, 0.05 to 0.2 percent of methionine, 0.3 to 0.4 percent of common salt and 1percent of premixing material. Due to the combination of steam explosion of straw and microorganism fermentation treatment, the method has the advantages of improving nutritive value and utilization rate of the corn straw, making changing the waste crop straw into the valuables possible, partially replacing the corn in the pig and chicken feed, improving the daily gain of livestock and poultry, having good feeding effect and bringing huge economic benefits.
Description
technical field [0001] The invention belongs to the technical field of feed for livestock and poultry, and in particular relates to a grain-saving feed formula for livestock and poultry which uses biologically fermented straw to replace part of corn. Background technique [0002] The shortage of food resources is a major problem facing the world. With the growth of population and the improvement of people's living standards, the rapid development of animal husbandry has been promoted, and the seriousness of the competition for food between humans and animals has been further aggravated. At present, 38% of my country's raw grain is used as animal feed, and it is estimated that this value will reach 50% by 2050. The lack of feed has become the main bottleneck restricting the development of my country's animal husbandry. According to statistics, the annual shortage of grain feed in my country has reached more than 30 million tons. How to tap feed resources has become more and m...
