Abstract

The invention discloses a grass additive. A process for preparing the grass additive comprises the following steps: (1) subjecting reaped grass to cleaning, draining, mixing, adding water, grinding straw pulp, sterilizing and deactivating various enzymes; (2) adjusting the grass, adding cellulase to subject the grass to an enzymatic hydrolysis reaction and enzyme inactivation, then adjusting the pH of the grass, adding hemicellulase to subject the grass to the enzymatic hydrolysis reaction, and performing enzyme inactivation for 5 minutes; and (3) drying, puffing and packing the obtained grass zymolyte and obtaining finished products. The grass additive utilizes the cellulase and the hemicellulase to perform the step-by-step enzymatic hydrolysis reaction, so that cellulose which is contained in trees and grass is subjected to partial degradation, the palatability of feeds is improved, the food intake of rabbits is increased, and the grass additive is beneficial to digestion and assimilation of rabbits.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive made of green grass. Background technique [0002] Green grass is often added to rabbit feed, but many grasses contain a lot of cellulose, which is not conducive to the digestion and absorption of rabbits, and has poor palatability, so rabbits are unwilling to eat. In order to overcome the above-mentioned defects of the prior art, the present invention uses cellulase and hemicellulase to degrade grass, aiming to provide a new grass feed additive, which is more beneficial to rabbits ingestion and digestion and absorption. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a green grass additive, which can degrade the cellulose in the green grass and improve the palatability of feed and the food intake of rabbits. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is ...
