Fermentation agent and preparation method of probiotics and straw fermented feed

Abstract

The invention discloses a fermentation agent and a preparation method of a probiotics and straw fermented feed. A fermentation agent of a ruminant animal fermented feed, a fermentation agent of a non-ruminant animal fermented feed and a fermentation agent of a poultry fermented feed are prepared from various probiotics; the ruminant animal fermented feed, the non-ruminant animal fermented feed and the poultry fermented feed are prepared from the corresponding fermentation agents; after straws are fermented, the feed is not mildewed, generates the certain sour fragrance and becomes a straw feed preferred by livestock; after the fermented feed is eaten by the livestock, pepsinogen is activated to be converted into pepsin for promoting protein decomposition, reducing gastrointestinal motility and shortening emptying time, so that the digestibility is improved. A formula of the fermentation agent is reasonable, a preparation method of the agent is easy to master, the preparation cost is low, the raw material application range is wide, the fermentation agent can be prepared and used on site all the year round without territory restriction, the human-powered transport is reduced, the palatability of the feed is relatively good, the daily gain and the meat-feed ratio are increased, and the disease resistance of the livestock is improved.

Description

technical field [0001] The invention relates to an animal feed, in particular to a starter and a production method of a variety of probiotic straw fermented feed and a production method of a variety of probiotic straw fermented feed. Background technique [0002] my country is a large agricultural country. For a long time, the development of animal husbandry mainly relies on grain and forage. This has become a deep-rooted traditional understanding of farmers. The contradiction between food and grain has become increasingly acute and difficult to coordinate. However, only about 20% of the more than 600 million tons of crop stalks produced in my country every year are used as feed for grass-eating livestock, and most of the rest are used as energy fuels or burned in vain. Since the 1950s, my country has begun to apply silage and ammonia treatment technology, using crop straw as feed for cattle, sheep and other large livestock, increasing the utilization rate of straw. In the ...

Problems solved by technology

[0003] Straw feed has high crude fiber content, especially a considerable amount of lignin and silicate, and very little protein content. The crude protein content of various straw feeds is low, and the crude ash content is high. The stalks were all relatively high, and the straw was not treated in any way, but it was only shortened to feed livestock. Although the feed intake increased, the digestibility could not be improved, the potential nutrients of the straw were not fully utilized, and the palatability was poor. The food intake is not very high, and the maintenance needs of livestock are also difficult to meet
