Problems solved by technology

[0003] In order to solve the above-mentioned deficiencies, the object of the present invention is to provide a non-protein nitrogen feed additive suitable for ruminants and its production method. The urea decomposition rate in the feed additive is coordinated with the rumen utilization rate to avoid ammonia accumulation in the blood causing ammonia Poisoning, while solving the shortcomings of poor palatability of urea

Abstract

The present invention discloses one kind of non-protein nitrogen feed additive for ruminant and its production process. The non-protein nitrogen feed additive has reasonable recipe, easy production, low cost, high decomposition speed, urea decomposing speed matching the utilization speed of rumen to avoid ammonia accumulation in blood and good taste. The non-protein nitrogen feed additive consists of urea 35-50 wt%, corn starch 35-48 wt%, and coating material 2-20 wt%, and its production process includes the steps of dispersing urea and corn starch in coating material solution, grinding in a colloid mill to form emulsion, and spray drying at normal temperature to form microspherical feed additive. It may be also produced into powder, granule, tablet or capsule.

Description

technical field [0001] The invention relates to a non-protein nitrogen feed additive suitable for ruminants and a production method thereof, belonging to the technical field of animal feed. Background technique [0002] Taking advantage of the ammonia availability of microorganisms in the rumen of ruminants, non-protein nitrogen is often used in ruminant feed instead of protein feed to save protein resources. Urea has the advantages of high nitrogen content and low production cost. In the case of insufficient animal and plant protein feed resources and high prices, it is a non-protein nitrogen source worthy of in-depth development. Studies have shown that urea feed can make the rumen microorganisms of cattle and sheep grow and multiply rapidly. After feeding, cattle and sheep can significantly increase the feed intake of forage grass by 15-20%, and improve the digestibility by 20%. Generally, the daily milk increase of dairy cows is 5-10%, and the milk fat rate is increased...
