Abstract

The present invention relates to the technical field of enzyme preparation applications, and specifically provides a keratinase preparation, which comprises neutral protease, hydrogen phosphate and zinc chloride. According to the present invention, with the synergetic effect of the neutral protease and the zinc chloride, the digestion rate of the keratinase preparation on the feed protein raw materials can be significantly improved, and the unexpected technical effect is provided; and the enzyme preparation can be widely used in feeds, and has effects of effective reduction of the protein raw material addition in the feed, production cost reducing, and farmer economic benefit increasing.

Description

technical field [0001] The invention relates to the application field of enzyme preparations, in particular to a keratinase preparation and its application in feed. Background technique [0002] Protein is an essential nutritional factor for animals. Most livestock get their essential protein from plant or animal protein sources, such as fishmeal, beans, and grains such as corn and wheat. However, monogastric animals, such as pigs and poultry, cannot fully digest the protein raw materials in the feed. Especially for piglets and pigs in the growing period, their ability to digest protein is only about 80%. Therefore, the utilization rate of protein raw materials in the current feed is low, and there is a large degree of waste. [0003] On the other hand, there is an increasing shortage of protein raw materials for feed in the world, and the price continues to rise. It is reported that my country's soybean imports have increased from 10.42 million tons in 2000 to 54.8 mill...
