Complex enzyme preparation for growing and fattening pig feed

Abstract

The invention discloses a complex enzyme preparation for a growing and fattening pig feed. The complex enzyme preparation for the growing and fattening pig feed comprises the following eight enzymes: acid protease, amylase, beta-mannase, xylanase, beta-dextranase, cellulase, pectinase and phytase; and the enzyme activity ratio of the eight enzymes is sequentially 1: (0.8-14.5): (0.19-0.3): (33.7-35): (25-30): (3.2-3.5): (0.19-2.0): (0-0.025). The complex enzyme preparation can degrade various anti-nutritional factors in the feed, reduce the chime viscosity of the intestinal tract, improve the metabolic energy of the feed, improve the digestion rate of growing and fattening pigs on protein and starch, reduce the nutrient content of the chime entering the intestinal tract, effectively inhibit the reproduction of harmful microbes in the intestinal tract, reconcile the micro-ecological balance of the intestinal tract, promote the health of the pigs, improve the average daily gain of the growing and fattening pigs, reduce the feed-meat ratio, shorten the maintenance period and improve the economic benefit.

Description

technical field [0001] The invention relates to a compound enzyme preparation for growing and finishing pigs. Background technique [0002] Feed compound enzyme is a new type of active feed additive, which is a mixed preparation of various digestive enzymes, and its main functional factors are endogenous digestive enzymes and exogenous digestive enzymes. Endogenous digestive enzymes mainly include amylase, protease and lipase. Exogenous digestive enzymes are similar enzymes that cannot be secreted by the digestive tract, including cellulase, pectinase, galactosidase, β-glucanase, and phytase. Exogenous enzymes cannot directly digest and hydrolyze macromolecular nutrients, but hydrolyze or hydrolyze anti-nutritional factors in feed, which indirectly promotes the digestion and utilization of nutrients. [0003] Compound enzyme preparations mainly include the following categories: (1) Feed compound enzymes mainly composed of protease and amylase, mainly used to supplement the...
