Slow release non-protein nitrogen bulking fodder and its preparing method

Abstract

The slowly releasing non-protein nitrogen bulking fodder consists of non-protein nitrogen 90-110 weight portions, metal chelate 0.5-1.5 weight portions, macromolecular organic compound 0.8-2.5 weight portions, emulsifier 1-3 weight portions, condensating agent 1-3 weight portions, energy coating agent 8-12 weight portions, adsorbent 8-12 weight portions, dispersant 0.8-2.5 weight portions, and water 0.5-1.5 weight portions. The preparation process includes chelating, emulsification, mixing, energy coating, condensation and puffing. The slowly releasing non-protein nitrogen bulking fodder has simple preparation process, good taste, good dispersivity and other advantages.

Description

technical field [0001] The present invention relates to the composition of non-protein nitrogen (NPN) feed and its preparation process. Background technique [0002] Non Protein Nitrogen (NPN) has been widely used in animal feed and can replace part of the plant protein in the feed. Non-protein nitrogen can be utilized by some animals, such as ruminants and aquaculture animals. The principle of utilization is to effectively convert non-protein nitrogen into bacterial protein through rumen or digestive tract microorganisms, and be absorbed and digested by animals and transformed into the body's own protein. The source of non-protein nitrogen raw materials is wide, easy to get, cheap, and can be produced on a large scale, providing high-quality and cheap protein resources for ruminants and aquaculture animals. The non-protein nitrogen slow-release technology currently used has the disadvantages of fast slow-release speed, low utilization rate, poor palatability, poor evacuat...
