Abstract

The invention discloses a mineral high-nitrogen composite nutrient for ruminant livestock. On a basis of ruminant non-protein nitrogen nutrition researches, the invention discloses the mineral high-nitrogen composite nutrient. According to the invention, ruminant mineral nutrition, rumen degradation speed of non-protein nitrogen-containing substances, and the ratio of a nitrogen source and other nutrients are taken into consideration. The invention intends to provide a high-efficiency and low-cost nutrient for proving a nitrogen source and trace elements for ruminant livestock. According to the invention, a urea molecular structure is changed. Urea is subject to a reaction with phosphoric acid, such that a transparent solution is obtained; a stabilizer is added to the solution; calcium sulfate, copper sulfate, magnesium sulfate, cobalt chloride, sodium selenite, bentonite and a curing agent are added to the solution; and an insoluble solid with a homogenized quality is obtained through a one-step addition reaction. The product provided by the invention can be produced into powder and prepared into a fine feedstuff with other feedstuff raw materials. Also, the product can be solidified during a production procedure, and prepared into sustained-release pellets in molds. The nutrient provided by the invention is advantaged in simple technology, low production cost, and no environmental pollution.

Description

The high nitrogen composite nutrient of ruminant domestic animal mineral matter

1. technical field

The invention belongs to ruminant animal nutrition control technique and slowly-releasing technical field, the present invention relates to chemical synthesis and mixes solidification technology.

2. background technology

Protein is that all animals earn a bare living and produce requisite nutrient, the protein resource of animal husbandry production labor, and therefore, the cheap grain-saving type protein substitute products of exploitation seem particularly important.Early stage discovers that the rumen microorganism of ruminant domestic animal can utilize the nitrogenous thing synthesising thalli proteins of non-albumen such as urea, and these mycoproteins are good protein sources of host animal.Yet rumen microorganism utilizes nonprotein nitrogen to have a serious limit factor, and promptly nonprotein nitrogen can not be utilized by microorganism in the degradation in cud excessive velocities effectively, causes ammonia to be accumulated thus, consequently domestic animal ammonia poisoning.In order to address this problem, researchers have done unremitting effort.Some is intended to slow down rumen microorganism through the molecular structure that changes the nitrogenous thing of non-albumen degrades to it, like hydroxymethyl urea, urea phosphate; Some forms one deck dressing on the nitrogenous thing of non-albumen, like the various urea that encapsulate, also some utilizes urea and carbohydrate to react, like the expanded urea of starch.Although these products have played controlled release or slow release effect, prescription is single, does not consider the mutual work of nitrogen and other nutrient, especially with the mutual work of sulphur.Other mineral matter such as calcium, phosphorus, magnesium, and trace quantity mineral substance element such as copper, cobalt, selenium, iron, iodine etc. all are that microorganism and domestic animal growth institute is essential.This seminar was studied compound, the slowly-releasing and the moulding problem of nitrogen and mineral matter from March, 2007, and accomplished product development and product index test in December, 2008.

3. the content of inventing

The present invention is on the basis of ruminant nonprotein nitrogen nutrient research; In conjunction with the ruminant mineral matter nutritional; Both considered to reduce the cud degradation speed of the nitrogenous thing of non-albumen; Consider the proportioning between nitrogenous source and other nutrient again, in the hope of efficiently, to ruminant domestic animal nitrogenous source and trace element are provided at low cost.For this reason; We set about from changing the urea molecule structure; With urea and phosphatase reaction, obtain transparent solution, add stabilizing agent to this solution; Add calcium sulfate, copper sulphate, magnesium sulfate, cobalt chloride, sodium selenite, bentonite, curing agent again, produce the insoluble solid of quality homogeneous through a step addition reaction.The present invention has the advantage of uniqueness owing to said prescription and manufacture craft technology: the compound nutrient product that can produce Different Nutrients content according to domestic animal to the nitrogen and the needs of trace element.We both can be made into powder and other feedstuff mixed preparing concentrated feed by the product of invention, also can it solidified, and in mould, processed the slowly-releasing bullet.The present invention also has characteristics such as technology is simple, cost is low, pollution-free.

4. the specific embodiment:

Ruminant domestic animal all can utilize the nitrogenous thing of non-albumen without any exception; This is their general character; In this respect; Be not exist specificly between different ruminants, so the high nitrogen composite nutrient of ruminant domestic animal mineral matter of our invention is fit to all ruminants, unique different be that the ruminant of different cultivars, different physiological stages is different to the requirement of nitrogen and mineral matter.

Example 1: add the high nitrogen composite nutrient of ruminant domestic animal mineral matter in the cattle diet: filling a prescription is: urea 20%-30%, phosphoric acid 20%-30%, calcium sulfate 10%-25%; Sodium sulphate 3%-6%, bentonite 5-15%, curing agent 4-7%; Stabilizing agent 3-5%, composite trace element salt 0.1%-0.3%.Above raw material can add in the beef concentrate through pulverizing by the solid of certain procedure reaction back formation homogeneous.Cattle diet was smart thick than being 1: 1 when this product was used in suggestion, and the adding proportion of the high nitrogen composite nutrient of ruminant domestic animal mineral matter in fine fodder is 10%.

Example 2: the high nitrogen composite nutrient of grazing sheep supplementary feeding ruminant domestic animal mineral matter: it is the same to fill a prescription.Can this product be processed into 20 centimetres of diameters in mould, weigh the fragment of brick that 5 kilograms confession pasture stock licks; Licking brick is placed on special wooden licking in the brick box and feeds; Lick that the brick box can be placed on the ground or hopper in, also can fix on the wall or the cowshed wall on conveniently to lick.As far as every adult sheep, the high nitrogen composite nutrient of lump ore material brick should have been licked in 70 days.Licking dosage can control like this: lick half an hour before going out to herd every morning, licked half an hour again after evening, receipts were herded.
