Problems solved by technology

The digestion of fibrous substances in feed by animals mainly depends on microbial fermentation in the digestive tract. Therefore, crude fiber feed such as straw is only suitable for feeding ruminants such as cattle and sheep, but its palatability is poor, the digestibility of organic matter is low, and the feed intake of poultry is limited. Lignin is difficult to digest and absorb

Abstract

The invention discloses a method for preparing straw ammoniation feed from oilseed rape straw as a raw material, and belongs to the technical field of straw ammoniation feed production. The method comprises the following step: by taking oilseed rape straw as the raw material, performing ammoniation fermentation treatment, thereby obtaining the straw ammoniation feed. The method is simple in process, low in production cost, and is not limited by weather or season; the product can be stored for a long time and is easy to popularize; waste of oilseed rape straw can be reduced, and the utilization rate of oilseed rape straw can be increased; the feed produced in an ammoniation fermentation manner is soft and juice, sour and sweet in taste, fragrant in smell, good in palatability, can promote digestive gland secretion, and has a good function of improving feed digestibility; the feeding test shows that the palatability of the feed is remarkably improved, the cattle feeding amount is increased by 15-20%, the digestibility of organic matters such as cellulose and hemicelluloses can be improved by about 15%, the feed is high in nutrition value and rapid to absorb, the daily gain of fed cattle is increased by 3-5%, and the feed conversion ratio is reduced by 5-10%.

Description

technical field [0001] The invention belongs to the technical field of straw ammoniated feed production, and in particular relates to a method for producing ruminant fermented feed by ammoniating rape straw as a raw material. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's dietary structure is also gradually changing, and the proportion of meat, eggs and milk is constantly increasing. Vigorously developing animal husbandry is the only way to effectively solve the contradiction between supply and demand of animal husbandry products in our country. However, the material conditions to support the rapid development of animal husbandry by relying on a large increase in grain no longer exist, and the development of animal husbandry is facing the severe challenge of shortage of feed grain. Therefore, optimizing the structure of feed production and establishing a low-consumption an...
