Abstract
The invention relates to an animal feed, and in particular relates to a livestock and poultry protein feed which is prepared from urea and formaldehyde taken as main materials, and a preparation method of the livestock and poultry protein feed. According to the feed, a low-molecule condensation product is used as the main ingredient; an appropriate quantity of corn powder, soya bean meal, phagostimulant and the like are added; and the total nitrogen content is 15-17% and is 93.8-106.3% after being converted into crude protein. The addition of auxiliary components aims at improving the taste of hydroxymethyl urea, increasing the nutrition value of a product and improving the utilization efficiency of the low-molecule condensation product. Due to the successful research of the product, the feeding security of non-protein nitrogen is improved, the palatability of the non-protein nitrogen is improved, the production cost of the non-protein nitrogen is lowered, and the economic benefits of users are increased.
Description
Technical field
The present invention relates to a kind of animal feed, specifically relate to and utilize urea and formaldehyde to be primary raw material, be processed into a kind of livestock and poultry protein feed and preparation method thereof.
Background technology
At present, the most frequently used nonprotein nitrogen kind mainly is urea both at home and abroad, and urea is the compound that ammonia and carbon dioxide form under HTHP, and its total nitrogen content is 46%, and being scaled gross protein value is 288%, is equivalent to 7 times of dregs of beans protein.In general, urea itself is nontoxic, but the ammonia that it discharges through the urase hydrolysis in cud is to the toxic effect of animal.Therefore, want to guarantee that urea brings into play trophism to greatest extent, the most important thing is urea searched for food enter cud after, control and slow down the rate of release of ammonia so that keep low ammonia concentration in the cud, thereby prevent ammonia poisoning and promote the utilization of urea.Method commonly used mainly contains at present: 1, add urease inhibitor, thereby reduce the hydrolysis rate of urea; 2, urea is coated with processing or makes slow-release carbamide; 3, make the urea ensiling; 4, improve the mode of feeding of urea, increase the frequency or make urea and lick brick of feeding, reduce each urea amount of taking in; 5, urea being carried out chemical synthesis, is corresponding derivative with Urea Transformation.These methods respectively have its pluses and minuses.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, one livestock and poultry protein feed is provided, this feed is as Main Ingredients and Appearance take low molecule condensation product, by adding an amount of corn flour, dregs of beans, phagostimulant etc., its total nitrogen content is 15-17%, and being scaled crude protein content is 93.8-106.3%.The purpose of adding complementary composition is to improve the mouthfeel of methylolurea, and increases the nutritive value of product, improves the utilization ratio of low molecule condensation product.This product development success, the raising security that has improved nonprotein nitrogen has improved the palatability of nonprotein nitrogen, has reduced the production cost of nonprotein nitrogen, has improved user's economic benefit.
The present invention realizes with following technical scheme: a kind of livestock and poultry protein feed, it is characterized in that: this feed carries out the Low Temperature Thermal reaction and is composited with on the basis of the low molecule condensation product that urea and formolite reaction were generated behind interpolation dregs of beans, corn flour, phagostimulant, the abundant mixing of catalyst.
Described phagostimulant is that the fish raw meat is precious; Described catalyst is zinc chloride or ammonium chloride.
The method for preparing livestock and poultry protein feed as claimed in claim 1 is characterized in that comprising the steps:
(1) takes by weighing in proportion each raw material urea, formaldehyde, corn, dregs of beans, phagostimulant, catalyst;
(2) formalin of adding 37% in reactor, and the interpolation catalyst, be 7-8 with the pH value of sodium carbonate conditioned reaction system, then reactor is heated to 50 ℃, add urea, reacted 2 hours, and then added dregs of beans, corn flour and phagostimulant (the fish raw meat is precious), abundant mixing, be warming up to 105 ℃, reacted 30 minutes, make wherein starch gelatinization, drying;
(3) discharging; Be cooled to natural temperature and get yellowish-brown or yellowish-brown object; Pulverize 3mm and sieved to get the powdery finished product.
Advantage of the present invention is: this feed is that by adding the complementary compositions such as an amount of corn flour, dregs of beans, phagostimulant, its total nitrogen content is 15-17% take low molecule condensation product as Main Ingredients and Appearance, and being scaled crude protein content is 93.8-106.3%.The purpose of adding complementary composition is to improve mouthfeel, and increases the nutritive value of product, improves the utilization ratio of low molecule condensation product.
The specific embodiment
The invention will be further described below in conjunction with embodiment and application test example;
Embodiment,
The formalin (being converted into 16 parts of butts) that in reactor, adds 43 part 37%, and add 1 part of catalyst, pH value with sodium carbonate conditioned reaction system is 7-8, then reactor is heated to 50 ℃, add 100 parts in urea, reacted 2 hours, then add 10 parts of dregs of beans, 1 part of 150 parts of corn flour and phagostimulant (the fish raw meat is precious), fully mixing is warming up to 105 ℃, reacted 30 minutes, make wherein starch gelatinization, the dry Maillard reaction generation fragrance that also passes through appropriateness, be cooled to natural temperature, pulverized again 3mm and sieve to get yellowish-brown or yellowish-brown powdery finished product.
Claims (3)
1. livestock and poultry protein feed is characterized in that: this feed is with on the basis of the low molecule condensation product that urea and formolite reaction were generated, and adds to carry out the Low Temperature Thermal reaction behind dregs of beans, corn flour, phagostimulant, the abundant mixing of catalyst and be composited.
2. livestock and poultry protein feed according to claim 1 is characterized in that: described phagostimulant is that the fish raw meat is precious; Described catalyst is zinc chloride or ammonium chloride.
3. the method for preparing livestock and poultry protein feed as claimed in claim 1 is characterized in that comprising the steps:
(1) takes by weighing in proportion each raw material urea, formaldehyde, corn, dregs of beans, phagostimulant, catalyst;
(2) formalin of adding 37% in reactor, and the interpolation catalyst, be 7-8 with the pH value of sodium carbonate conditioned reaction system, then reactor is heated to 50 ℃, add urea, reacted 2 hours, and then added dregs of beans, corn flour and phagostimulant (the fish raw meat is precious), abundant mixing, be warming up to 105 ℃, reacted 30 minutes, make wherein starch gelatinization, drying;
(3) discharging; Be cooled to natural temperature and get yellowish-brown or yellowish-brown object; Pulverize 3mm and sieved to get the powdery finished product.
