Abstract

The invention discloses a piglet feed complex enzyme preparation and a production method and application thereof. The complex enzyme preparation comprises the following enzyme activity components: 80-100U / g of glucose oxidase, 20-25U / g of alpha-galactosidase, 3000-4000U / g of xylanase, 500-600U / g of beta-dextranase, 500-600U / g of beta-mannase, 2000-3000U / g of acid proteinase, 800-1000U / g of neutral protease, 800-1000U / g of medium-temperature alpha-amylase, 400-500U / g of fungus alpha-amylase and 3000-4000U / g of glucamylase. According to the complex enzyme preparation, a mixture of corn starch, monopotassium phosphate, dipotassium phosphate and calcium sulfate serves as a diluent. The using method of the complex enzyme preparation comprises the step of adding 500-750g of complex enzyme preparation into every ton of piglet complete formula feed.

Description

technical field [0001] The invention relates to a suckling pig feed compound enzyme preparation capable of improving the feed digestibility of suckling pigs, reducing the diarrhea rate and improving the feeding environment, as well as its production method and application. Background technique [0002] The health of suckling piglets is the most important link in the whole pig breeding production and the key to the success of breeding. In order to improve the productivity of sows and reduce feeding costs, modern intensive pig farms advance the weaning age of piglets to 3 to 5 weeks old. Due to factors such as early departure from the sow, mutations in nutrient sources, and other stressors, early weaning can easily lead to decreased immunity of piglets, intestinal microecological disorders, gastrointestinal mucosal lesions, and inability to digest and absorb dietary nutrients normally. , At the same time, it causes a series of changes in the blood, endocrine and nervous syste...
