Temperature-resistant feed enzyme preparation composite

Abstract

The invention belongs to the technical field of feed additives, and particularly relates to a temperature-resistant feed enzyme preparation composite. The temperature-resistant feed enzyme preparation composite comprises the components of apoenzyme and a vector, wherein the apoenzyme comprises acidic cellulase, neutral cellulase, acidic xylanase, neutral xylanase, acidic proteinase, neutral proteinase, high-temperature resistant alpha-amylase, acidic mannase, neutral mannase and glucose oxidase; the vector comprises fermentation slag of the enzymes, glucose, sucrose, trehalose, stevioside, chitosan, maltose and levulose. The enzyme preparation composite provided by the invention can not only meet the requirement for degradation effect of antinutritional factors contained in different feed raw materials, but also reduce the enzyme activity loss ratio in the high-temperature granulating process of a feed.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a temperature-resistant feed enzyme preparation composition. Background technique [0002] Feed enzyme preparation is a new type of additive in the feed industry. It started in the late 1970s in foreign countries. Since the 1980s in my country, the single enzyme introduced from abroad has been tried to be used in livestock and poultry breeding. [0003] Due to the relatively simple function of a single enzyme, most of the current feed industry is dominated by compound enzymes. The existing compound enzymes have the following two sources: (1) The same strain produces multiple enzymes during the fermentation process, with one enzyme with high enzyme activity as the main activity and other enzymes as the secondary activity, but such a strain The disadvantage of fermentation is that the enzyme activity is generally low, the fermentation cost is high, and it does not meet the ...

The existing compound enzymes have the following two sources: (1) The same strain produces multiple enzymes during the fermentation process, with one enzyme with high enzyme activity as the main activity and other enzymes as the secondary activity, but such a strain The disadvantage of fermentation is that the enzyme activity is generally low, the fermentation cost is high, and it does not meet the requirements of the feed industry for low cost and high enzyme activity; (2) Another source of compound enzymes is single enzymes produced by fermentation of different strains, combined with feed materials As well as the characteristics of the animals to be fed, the product after compounding has low price and high enzyme activity, so the corresponding cost performance is high. At present, this product is basically the main product in China.

[0004] Because the former compound enzyme is produced by the same strain of bacteria, the coordination and synergistic effect of the enzyme are very good, but the cost is high, and it cannot meet the needs of livestock and poultry in the feed industry; although the latter product can meet the production needs, the enzyme preparation After being mixed with the feed, it needs to be granulated at high temperature. The enzyme is a kind of protein. Under high temperature conditions, the active center of the enzyme will be destroyed, which will reduce the activity of the enzyme. It has been found through research that the enzyme activity after high temperature granulation can only reach the level of granulation. 60% of the former enzyme activity, a huge loss
