Problems solved by technology

In recent years, with the rise in the price of energy raw materials such as corn, cassava has gradually been promoted as a substitute for energy feed for livestock breeding. However, due to the relatively short storage time of cassava and the high content of cyanide in cassava, there will be cyanide in the preparation of feed. The risk of chemical poisoning. After testing, the cyanide content in cassava skin can be as high as 1062.11 μg / g, and the cyanide content in cassava meat can be as high as 38.48 μg / g. In the process of using cassava to prepare food or feed, it is often reduced by peeling Cyanide content, however, cassava skin is still rich in nutrients, peeling not only the preparation process is troublesome but also causes waste, the utilization rate of cassava is low, making cassava feed have no competitive advantage

Abstract

The invention relates to the fields of feeds and processing technologies thereof, and especially relates to a biological feed for cassava, and a preparation method and a use thereof. The biological feed for cassava is prepared through mixing cassava, auxiliary materials and probiotics according to a weight ratio of (40-50:)(15-20):(1-5) and fermenting the obtained mixture. The most main component of the biological feed is cassava, molasses and corn flour are added to the cassava, and fermentation is carried out to improve the nutrition values of the obtained fermentation feed, the molasses and corn flour in the auxiliary materials in the above formula provide enough energy, tea powder can neutralize hydrocyanic acid and adsorb cyanides, and applied plant extracts comprising finely divided phtheirospermum root extract, licorice root extract and guava leaf extract are alkaline, can neutralize the hydrocyanic acid to a certain degree, also can inhibit the growth of competitors and improve the growth of beneficial bacteria, are extracted from plant sources, are more safe than chemical removal of the hydrocyanic acid, and are suitable for being used in the animal feed to improve the palatability of the feed and promote the growth of animals.

Description

【Technical field】 [0001] The invention relates to the technical field of feed and its processing, in particular to a cassava biological feed and its preparation method and application. 【Background technique】 [0002] Cassava is the main economic crop in Guangxi. It has the characteristics of drought resistance and high yield. At present, it is mainly used as raw material for starch production. In recent years, as the price of energy raw materials such as corn has risen, cassava has gradually been promoted as a substitute for energy feed for livestock breeding. However, due to the relatively short storage time of cassava and the high content of cyanide in cassava, there will be cyanide in the preparation of feed. The risk of chemical poisoning. After testing, the cyanide content in cassava skin can be as high as 1062.11μg / g, and the cyanide content in cassava meat can be as high as 38.48μg / g. In the process of using cassava to prepare food or feed, it is often reduced by peel...
