Abstract
A slow-releasing urea-in-molasses feed is prepared proportionally from urea, wheat brane, molasses, starch, alum, wheat flour and bentonite. Its application is also disclosed.
Description
Technical field
The present invention relates to the feed addictive of a kind of feeding ruminant, relate in particular to edible molasses coated urea slow-released fodder composite of a kind of ruminant and its preparation method and application.
Background technology
Urea is a kind of in the nonprotein nitrogen, PE is high, reach 293%, a kind of that present domestic and international application is the most general, price is the most cheap, it is similar to the principle that vegetable protein is employed to the application principle of ruminant: urea is decomposed ammonification and carbon dioxide by a part of microorganism in ruminant tumor gastric, ammonia is utilized synthesising thalli protein by a part of microorganism again, digested absorption in abomasum; And vegetable protein is decomposed ammonification, amino acid and peptide, the digested absorption in abomasum of a part of microorganism and ammonia synthesis mycoprotein by a part of microorganism when being employed.
Because the urea PE is high, the a quite albumen of 6-7 part dregs of beans, this causes attention both domestic and external, the whole world is all at research urea, application urea, 1,000,000 tons of the U.S.'s annual product urea series products, more than 60 ten thousand tons of the annual application of former Soviet Union's eighties in 20th century, Europe, all states in Australia also use ten thousand tons of 50-60 every year. These urea albumen can be used to replace in the feeding ruminant plant protein fodder at least 1/3 vegetable protein, thereby economize in raw materials, and improve the intake of feeding animals.
Urea-containing feed product both domestic and external is divided into following a few class at present: one, urea deep processed product such as biuret, is urea further to be heated make, and its shortcoming is price; Two, plastered starch urea is to mix with urea to heat, pressurize with corn to carry out gelatinization, and shortcoming is that slow release effect is bad; Three, urease inhibitor suppresses biological urease activity with metallic salt, shortcoming be simultaneously other microbial activities to having suppressed, affected and digested and assimilated; Four, coated or coated urea is with other material urea to be wrapped, and urea is slowly discharged, and shortcoming is too expensive. Work out at present the urea fodder product, all because there are the problems referred to above in the urea fodder product, and urea is directly fed to exist easily and is poisoned, mouthfeel is bitter, and the two large shortcomings that palatability is poor add that production technology falls behind, production line is complicated, loss is large, and cost is high, fails so far to produce in enormous quantities and large standard application.
Summary of the invention
The purpose of this invention is to provide a kind of molasses coated urea slow-released fodder composite, overcome the shortcoming of above-mentioned urea product, have good palatability, do not poison, low-cost advantage.
The objective of the invention is to be achieved through the following technical solutions:
A kind of molasses coated urea slow-released fodder composite is by the feed that comprises that following weight portion raw material is prepared from: urea 20-40, wheat bran 10-30, molasses 15-35, starch 3-7, alum 0.2-0.8, flour 8-12, bentonite 8-12; Described raw material components is preferably following parts by weight of component: urea 30, wheat bran 20, molasses 25,, starch 5, alum 0.5, flour 10, bentonite 9.5.
Described fodder compound is preferably granule.
The byproduct that wheat bran described in the present invention remains when being the processing wheat; Described molasses can also use brown sugar, white sugar, granulated sugar to replace; Described flour is the known Cereal flour such as wheat flour, corn flour, and the bentonite chemical name is (N2，C
2)
0.33(Al，Mg)
2(SiO)
10(OH)
2nH
2O)。
The present invention also provides a kind of preparation method of molasses coated urea slow-released fodder composite, may further comprise the steps:
Take by weighing in proportion raw material urea, wheat bran, molasses, starch, alum, flour, bentonite; Molasses are soluble in water, preferably soluble in water with 1: 2 ratio; With other raw material co-grinding in proportion, sieve the most well 2 mm sieve; Raw material after the pulverizing and molasses water mix and blend carry out saccharification; Saccharificatinn period is 5-15 minute, best 10 minutes; Raw material after the saccharification send in the granulator granulates, and without steam, by the temperature of friction, urea dissolves in the friction process fully, and between the raw material space that urea has been pressed against by saccharification, this temperature is 50-80 ℃, pressure 2-3kg/mm2, drying is made the particle of 3-5 millimeter.
Granulator of the present invention can be the plain particles machine, such as the fish feed pellets machine.
The present invention also provides the application of a kind of molasses coated urea slow-released fodder composite in the ruminant feed for nursing.
Described molasses coated urea slow-released fodder composite is as the application in the ruminant feed, that described molasses coated urea slow-released fodder composite is added in the normal diet in the ratio of 3%-5%, this normal diet is feed common on the market, the feed that is made into such as corn, dregs of beans, plants and vegetables etc.
The present invention has the following advantages:
1, with molasses urea is tightly wrapped up, granulation had both solved the urea bitter, and the shortcoming that palatability is poor has solved again the problem that urea is easily poisoned, and price is also cheap.
2, starch, alum, flour, bentonite are that natural adhesive is in processes of mixing and granulating among the present invention, play extremely strong cementation, urea can slowly be decomposed, the ammonia that decomposes slowly discharges, animal edible is not poisoned, after the ruminant such as ox, sheep is edible, fast growth, give milk manyly, the milk quality is high.
3, the inventive method is simple, and mechanization degree is high, is convenient to large-scale production;
4, this product has been filled up a blank in this field.
The present invention has above advantage for proof, the present invention has carried out embodiment 1 described molasses coated urea slow-released fodder composite feeding of ruminant animals test, test group is made into smart supplementary feeding material with molasses coated urea slow-released fodder composite and the normal diet of embodiment 1, and control group is made into smart supplementary feeding material with molasses coated urea slow-released fodder composite and the normal diet of embodiment 1; The present composition or premix proportioning ratio in smart supplementary feeding material is 5%, and this normal diet contains 60% corn, 20% dregs of beans, 10% cotton dregs, 5% plants and vegetables and an amount of trace element, result such as table 1 and table 2.
