Method for preparing livestock feed and feed prepared by the method

Abstract

The invention relates to a method for preparing livestock feed by using stems and leaves of annual plant through low-temperature drying method. The water content of the feed prepared by the low-temperature drying method is kept in the range of 5%-13%, the green appearance of the feed is also maintained, and the most of superoxide dismutase (SOD) and protein (Protein), and various organic active matters in the leaves and stems are not damaged.

Description

technical field [0001] The present invention relates to a method for preparing animal feed, more specifically a method for preparing animal feed with stems and leaves of annual plants using a low-temperature drying method. Background technique [0002] We know that the leaves and stems of plants are rich in various vitamins, organic ketone materials, cellulose, organic active substances, such as superoxide dismutase, leaf protein, antioxidant substances and so on. However, when a large number of plant leaves and stems need to be processed, improper methods, such as high-temperature drying, will cause a large number of active substances to lose their activity. For example, substances such as superoxide dismutase (superoxide dismutase SOD) and leaf protein will coagulate and lose activity of protein substances at a temperature higher than 60° C., especially the loss of activity of superoxide dismutase is a very unfortunate thing. If animals, such as dairy cows, eat a large am...
