Abstract
A slow-releasing non-protein nitrogen feed for domestic animals and fowls is prepared from corn flour, urea, bentonite, brown sugar and soybean through pulverizing, proportionally mixing, puffing, cooling and breaking. It features that the urea particles are wrapped by starch membrane to elongate its hydrolyzing time to 3-4 hr, so preventing poisoning.
Description
Technical field:
The invention belongs to the prescription and the technical field of producing of animal and fowl fodder, specifically is the feed formula of a kind of ruminant and the production technology of producing this kind feed.
Background technology:
Along with social progress; science and technology development and market demand, the production of ruminant livestocks such as fattening beef cattle is raised from original natural extensive style, must carry out the transition to large-scale breeding; also require simultaneously ruminant feed from the roughage being main changing into based on concentrated feed; in order to save food, stabilize feed nutrition reduces feed cost; people adopt albumen supplement feed-urea as ruminant feed at present; urea fodder easily causes ammonia poisoning, and utilization rate is low but simultaneously.
Summary of the invention:
The technical problem to be solved in the present invention is to disclose a kind ofly can prevent that animal poisons, sustained-release non-protein nitrogen feed of increasing operation rate and the technology of producing this feed.
The scheme of technical solution problem of the present invention is to adopt corn flour, urea, bentonite, brown sugar, soy meal to constitute the composition of raw materials of feed, and its ratio of weight and number is:
Corn flour 60-70 (moisture content≤18%)
Urea 20-30 (nitrogen content 〉=46%)
Bentonite 3-5
Brown sugar 1-3
Soy meal 1-2
Its preferred feedstock formulation weight portion rate is:
Corn flour 63-68
Urea 22-28
Bentonite 4-5
Brown sugar 1-2
Soy meal 1-1.5
Its optimum feed stock formulation weight portion rate is:
Corn flour 66
Urea 25
Bentonite 5
Brown sugar 2
Soy meal 1
Its production process is:
Corn flour, urea, bentonite, brown sugar, soy meal are pulverized respectively, the granularity of the 60-80% of corn flour, urea can be sieved by 40 order analyses, by above-mentioned prescription requirement, raw material is mixed in proportion, water content is 18-22%, sends into to carry out expandedly in the bulking machine, and pressure is 1.0-1.5Mpa, temperature is 100-200 ℃, and expanded after cooling, fragmentation makes sustained-release non-protein nitrogen.
Raw material is under high temperature, high pressure effect, cornstarch in the pasty state, the urea dissolving, urea after the dissolving is absorbed by bentonite, be diffused in the corn starch paste, urea granules is surrounded by one deck starch film like this, is coated on time lengthening that the urea in the starch is hydrolyzed by 3-4 hour in the cud of ruminant, can avoid the rapid hydrolysis of urea to cause intoxicating phenomenon to improve feeding effect.
Shortcomings such as feed of the present invention has overcome traditional shortcoming of directly utilizing fertilizer urea method for breeding to exist, and it is loaded down with trivial details to have overcome technologies such as ammonification, alkalization, ensiling, little storage, seasonal strong, time-consuming have effectively utilized nonprotein nitrogen.
The specific embodiment:
Get 66 kilograms of corn flour, 25 kilograms in urea, 5 kilograms of bentonites, 2 kilograms in brown sugar,
1 kilogram of soy meal, pulverize respectively, the granularity of the 60-80% of corn flour, urea can be sieved by 40 order analyses, by above-mentioned prescription requirement, raw material is mixed in proportion, water content is 18-22%, send into carry out in the bulking machine expanded, pressure is 1.0-1.5Mpa, and temperature is 150 ℃, and expanded after cooling, fragmentation makes sustained-release non-protein nitrogen.
