Embodiment 1

[0014] A special compound enzyme for barley-type feed, the components and their contents are respectively: 10kg of β-glucanase, 25kg of cellulase and 10kg of xylanase. This is 1# complex enzyme.

Embodiment 2

[0016] A special compound enzyme for barley-type feed, the components and their contents are respectively: 13kg of β-glucanase, 20kg of cellulase and 7kg of xylanase. This is 2# complex enzyme.

Embodiment 3

[0018] A special compound enzyme for barley-type feed, the components and their contents are respectively: 15kg of β-glucanase, 22kg of cellulase and 5kg of xylanase. This is 3# complex enzyme.

[0019] The above-mentioned special compound enzyme for barley-type feed is obtained by weighing each component in the compound enzyme according to the above-mentioned ratio, and then fully mixing each component evenly.

Abstract

The invention relates to the field of feed additives and particularly provides a special compound enzyme for barley-based feed. The compound enzyme contains beta-dextranase, cellulase and xylanase and can increase the dry matter utilization rate and in-vitro digestible energy of the barley-based feed effectively, so that efficient digestion and absorption utilization of the barley-based feed are realized for livestock and poultry. The adding amount of the beta-dextranase in the compound enzyme is the key for affecting the effect of the compound enzyme, specifically, when the defined amount of beta-dextranase (the weight ratio of the beta-dextranase to the cellulase to the xylanase is (10-15):20:7) is added, the beta-dextranase can play a synergistic role on the effects of the cellulase and the xylanase in the compound enzyme, and accordingly, the comprehensive effect of the compound enzyme is optimal; however, when the beta-dextranase is added excessively, an antagonistic action is caused, the action effects of the cellulase and the xylanase can be inhibited to a certain extent, the comprehensive effect of the compound enzyme is reduced, and undesirable effects are realized.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a special compound enzyme for barley-type feed and its application. Background technique [0002] The growth of demand for feed grain has become an important factor affecting my country's future food security. Affected by the traditional feed formula, corn has been used as the main energy source in the energy feed of livestock and poultry for a long time, resulting in an increasingly tight supply of corn. Moreover, judging from the current supply and demand of energy feed in my country, it is obviously difficult to make up for the gap in energy feed only by increasing corn production. Therefore, finding, developing and replenishing new feed resources has become a hot topic for animal husbandry workers all over the world. The local solution of energy feed is of great significance to the development of national economy. [0003] Barley is highly tolerant to climate and can be grown...
