Abstract

The invention relates to cattle and sheep feed using potato dregs and bean curd dregs as main materials and a preparation method thereof, the feed contains the following components: the potato dregs, the bean curd dregs, alfalfa, corn flour, wheat bran, vitamins, trace elements, dried molasses, a lignin adhesive agent, a mildew preventive and a disintegrant. The feed formula has the advantages of high nutritive value, convenient feeding, low tendency to mildew, easy transport and storage, and achievement of the recycling of resources and other effects. Research shows that, the feed can better meet the nutrient substance needs of ruminant animals.

Description

technical field [0001] The invention relates to a feed for ruminants prepared from waste, in particular to a feed for cattle and sheep with potato dregs and bean curd dregs as main ingredients and a preparation method thereof. Background technique [0002] China is the largest potato producer in the world, with a planting area accounting for 1 / 4 of the world and a total output of about 1 / 5 of the world. With the change of industrial structure, the potato deep processing industry is also developing rapidly. At present, in most areas of our country, potato processing is mainly to extract starch, but with the development of starch industry, the pollution of potato residue is becoming more and more serious. Some documents point out that there are more than 700 large and medium-sized starch factories in my country at present, and the annual discharge of potato waste is about 4 million tons. [0003] As a by-product of tofu processing, bean curd residue is rich in nutrients, and...

Problems solved by technology

[0006] At present, there are patents on cattle and sheep feed prepared from bean curd and potato dregs, but their preparation mainly uses bean curd dregs and potato dregs as ingredients, and their consumption is far from meeting the needs of these wastes brought by industrial production. In terms of storage, this kind of feed is difficult to store and can only be prepared and used immediately. If it is not fed in time, it will easily make livestock sick after mildew; the palatability of roughage for cattle, sheep and other livestock is not very good, and there is a lot of crude fiber. Cattle and sheep do not like to eat and are difficult to absorb. The difference from traditional feed is not very big, and the benefits are not obvious. From a nutritional point of view, this type of feed cannot meet the needs of livestock for trace elements and vitamins. Long-term consumption may easily cause malnutrition in livestock. In addition, there is no patent that uses two kinds of industrial wastes, bean curd residue and potato residue, as feed at the same time.
