Problems solved by technology

[0003] 1. Formaldehyde reacts with urea to form hydroxymethyl urea and methylene diurea. They are degraded in animals or decomposed by urease. The intermediate product is formaldehyde. Formaldehyde is a toxic substance that can cause livestock poisoning
[0004] 2. Hydroxymethylurea decomposes quickly in animals, and methylidene diurea decomposes faster than the former...

Embodiment

[0030] 1. Add 52 grams of biuret and 200 grams of water into a reaction flask equipped with a stirrer, a thermometer and a reflux condenser, adjust the pH to 2.5-3.0 with acetic acid, add 18 grams of malondialdehyde, and set the temperature at 65-70 ℃, after reacting for 1 hour, move the reactant to a larger reaction bottle, add 190 grams of lysine residue, adjust the pH = 3.0-4.0, continue to reflux and stir for 1.5 hours, filter and dry to obtain non-protein nitrogen compound feed.

[0031] 2. Put 51 grams of acetylurea and 200 grams of water into a reaction flask equipped with a stirrer, a thermometer and a reflux condenser, adjust the pH to 3.0 with lactic acid, add 25 grams of glutaraldehyde, and react at a temperature of 60 to 65 ° C. After 1 hour, the reactant was moved into a larger reaction bottle, 200 grams of lysine raffinate was added, the pH was adjusted to 3.0, and the reaction was continued for 1.5 hours under reflux and stirring. After filtering and drying, a n...

Abstract

A compound feed is prepared from at least one of urea, biuret, acetylurea and allantoin, at least one of acetaldehyde, propanal, propanedial, butanal, butanedial, isobutanal and glytaraldehyde, and water through feeding them in a reactor, regulating pH to 2.0-3.0, reaction at 40-70 deg.C for 0.5-1.5 hr, adding lysine liquid and/or straw powder, regulating pH to 3.5-4.5, and reaction while stirring for 1-2 hr.

Description

1. Technical field [0001] The invention relates to a non-protein nitrogen compound feed and its preparation method and application. 2. Background technology [0002] At present, there is a general shortage of special protein feed for animal husbandry. It is impossible to further increase production simply by adding animal and plant proteins such as fish meal, bone meal and soybean meal to ordinary feed. This has become a bottleneck for the development of animal husbandry. Expanding protein resources has become an urgent need for animal husbandry. solved problem. Non-protein nitrogen is produced by chemical synthesis. Compared with animal and plant protein additives, it can be digested and absorbed by cattle and sheep to the greatest extent, achieving a feeding effect of twice the result with half the effort. The Colorado National University in the United States conducted an experiment on 80 high-yield dairy cows, and the effect of each kilogram of non-protein nitrogen feed ...
