Abstract

The present invention discloses a protein feed and method for preparing the same. The method for preparing the protein feed provided by the present invention obtains the protein feed by fermenting the flax. In the inventive protein feed, the content of the crude protein obviously increases relative to the raw material, the neutral detergent fiber is significantly reduced, thereby producing a large number of proteases and increasing the nutritional value. The products have sufficiently improved colors relatively to the raw material, aromatic smell, loose materials, improved foraging velocity and feed intake of the livestock, sufficiently improved palatability and improved biology valence of the flax feed. The method of the invention not only saves energy and simplifies the production process, and has advantages of high-yielding, simple process, low investment, low energy consumption, less covering and so on. The present invention has great economic value and social significance.

Description

technical field [0001] The invention relates to a protein feed and a preparation method thereof. Background technique [0002] Flaxseed, also known as flaxseed, is the seed of flax, a plant in the flax family. The world's flaxseed production has increased rapidly in the past decade, and China has become the world's second largest flaxseed producer next to Canada, with flaxseed production accounting for 20% of the world's total. Flaxseed oil is rich in about 73% polyunsaturated fatty acids and 18% monounsaturated fatty acids, making it a high-quality source of edible oil. During the preparation of linseed oil, a large amount of defatted meal will be produced. The linseed meal is rich in protein, lignans, soluble fiber, minerals and vitamins and other nutrients, which can well supplement the gap of protein feed in the market and is available important resource. At present, linseed meal cannot be effectively utilized, and only a small amount of linseed meal can be added to t...
