Abstract

The invention discloses a crude fiber and carbamide mixed condensation compound. On the basis of a ruminant non-protein nitrogen nutrition research and through the combination with a slow release technology, the crude fiber and carbamide mixed condensation compound is formed by condensation reaction of liquefied corn cobs, various leaves, various crop stalks, chaff and the like with carbamide by adopting a chemical condensation method. With the adoption of the crude fiber and carbamide mixed condensation compound, the ammonia release rate of carbamide in a rumen can be effectively reduced; the ammonia release rate of carbamide in the rumen is matched with the rate of ammonia used by rumen microbes, so that the utilization efficiency of non-protein nitrogen is ensured to the greatest extent; and as the ammonia release rate is low, the safety is further ensured. The crude fiber and carbamide mixed condensation compound can be processed either into powder to be mixed with other raw materials of feed to prepare concentrated feed, or into a lick block to be licked by ruminants. The crude fiber and carbamide mixed condensation compound has the characteristics of simple process, low preparation cost and no pollution to environment.

Description

Crude fibre urea mixed condensate

1. technical field

The invention belongs to the ruminant animal nutrition technical field.

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.Microorganism in the ruminant tumor gastric can be converted into microprotein with nonprotein nitrogen, and urea is a kind of as nonprotein nitrogen, because its source is wide, cheap, nitrogen content is high, is widely used in the ruminant feed, has obtained certain effect of increasing production.But urea is under the effect of ruminant tumor gastric microorganism urease, the ammonification that is decomposed very soon, and rumen microorganism utilizes the speed of ammonia synthesis mycoprotein then slower, and promptly release ammonia speed and the rumen microorganism of urea in cud utilizes the speed of ammonia not match very much.This not only reduces the utilization ratio of urea, and exist ammonia stress, the ammonia poisoning problem.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.What these products had been controlled urea to a certain extent releases ammonia speed; Reached utilization rate that improves urea nitrogen and the effect that prevents to poison, but some process of producing product relative complex, technical parameter requires harsh; Some product price is higher relatively, is not widely used.Occurring in nature has a large amount of all kinds of leaves, all kinds of stalk, corncob, husk etc. to be rich in coarse-fibred material; Can form the various carbohydrates that the degree of polymerization does not wait after their hydrolysis; In theory they can with the amino generation chemical reaction of urea, thereby reduce the ammonia speed of releasing of urea.Because these material wide material sources; Very be easy to get; It is the optimum feed stock of producing the slow-release carbamide product; This seminar from 2009 to all kinds of leaves, all kinds of stalk, corncob, husk etc. be rich in coarse-fibred material acidolysis condition, study with the problems such as reaction condition of urea, and accomplish product development and product index test in December, 2010.

3. the content of inventing

The present invention is to be theoretical foundation with ruminant novel protein system, is support with the slow release method, adopts chemical condensation reaction principle, invents out crude fibre urea mixed condensate, in the hope of efficient, safety, to ruminant domestic animal nitrogenous source is provided at low cost.Get corncob, all kinds of leaf, all kinds of agricultural crop straw, husk mixture 40%-50%; Add 20%-30% urea, and with the said mixture mixing, add the phosphoric acid of 30%-35%; Under 120 ℃ of conditions, reacted 1 hour then, can generate crude fibre urea mixed condensate.The present invention has taken into full account the ability nitrogen balance problem of ruminant nonprotein nitrogen product, can guarantee the utilization ratio and the security of products of product nitrogen to greatest extent.This product can be made into powder to be mixed with other feedstuff, preparation ruminant fine fodder compound.The present invention 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 crude fibre urea mixed condensate 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.

Example 1: add crude fibre urea mixed condensate in the cattle diet: corncob, all kinds of leaf, all kinds of agricultural crop straw, husk are pressed earlier arbitrary proportion mix; Process the coarse fodder mixture; Then by following prescription: coarse fodder mixture 40%-50%, urea 20%-30%, phosphoric acid 30%-35%.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 60 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.

Claims

1. material prescription of the present invention is: corncob, and all kinds of leaves, all kinds of agricultural crop straws mix formation coarse fodder mixture, mixture 40%-50%, urea 20%-30%, phosphoric acid 30%-35% with arbitrary proportion.

2. technical matters of the present invention is: get corncob; All kinds of leaves, all kinds of agricultural crop straw mixture 40%-50% add 20%-30% urea; And with the said mixture mixing; The phosphoric acid that adds 30%-35% reacted 1 hour under 120 ℃ of conditions then, can generate crude fibre urea mixed condensate.
