A kind of dwarf-type laying cycle of laying hens feed
Technical field
The present invention relates to a kind of chicken feed, specifically a kind of dwarf-type laying hen---the laying period premixed feed of No. three laying hens of agricultural university.
Background technology
Along with the continuous development of feed industry and animal husbandry, the output of feed rises, and the raw material that causes problem in short supply is also more and more serious, and country has developed the low laying hen product of a kind of feed intake, i.e. " brown No. 3 of agricultural university " dwarf-type laying hen for this reason.Its commodity are for the production performance height, 72 year in age week egg number can reach 260 pieces, about 58 grams of average egg weight, laying period daily material consumption 85-90 gram/only, feedstuff-egg ratio 2.1: 1.Raise 1 dwarf-type laying hen commodity for saving feed 8-10 kilogram, increase nearly 8 yuan of profit.The nutrition of common layer breed is different on laying period nutrition and other market, and crude protein content reaches 17%, and methionine content reaches 0.45%, and sulfur-containing amino acid reaches 0.7%-0.72%.And do not have No. three chicken feeds of special agricultural university, conventional way to be to use common egg feedstuff to feed on the market, therefore, No. three laying hen premixed feeds of agricultural university of developing a kind of special use are necessary.
Summary of the invention
The purpose of this invention is to provide a kind of dwarf-type laying cycle of laying hens feed, this kind feed is at the dwarf-type laying hen, and the laying rate height is laid eggs heavily.
The present invention adopts following technical proposals to realize:
A kind of dwarf-type laying cycle of laying hens feed, form by following components by weight portions: calcium monohydrogen phosphate 120-200 part, stone flour 260-300 part, salt 40-60 part,, sodium sulphate 20-40 part, betaine 2-6 part, choline 15-20 part, 40 parts of composite trace elements, 9 parts of B B-complexes, lysine 10-15 part, methionine 18-26 part, corn protein powder 150-200 part, medical stone 90-280 part, bacillus subtilis 1-3 part, phytase 2-5 part, complex enzyme formulation 2-5 part.
Described composite trace element is that two or more arbitrary proportions cooperations in ferrous sulfate, copper sulphate, manganese sulfate, zinc sulfate, sodium selenite, the calcium iodate form.
Described B B-complex is that two or more arbitrary proportions cooperations in vitamin A, cholecalciferol, vitamin E, prokeyvit, vitamin B1, vitamin B2, vitamin B6, cobalamin, nicotinic acid, pantothenic acid, folic acid, the biotin form.
Described complex enzyme formulation is that two or more arbitrary proportions cooperations in protease, amylase, cellulase, zytase, the 'beta '-mannase form.Wherein complex enzyme formulation can be bought in market.
Bacillus subtilis: bacillus subtilis can consume the free oxygen in the environment in the alimentary canal rapidly, forms the enteron aisle low-oxygen environment, promotes useful anaerobic bacteria growth, and produces organic acid such as lactic acid, reduces the enteron aisle pH value, suppresses the growth of other pathogenic bacteria indirectly; The bacillus subtilis thalline can self synthesize the digestibility enzyme, as protease, amylase, lipase, cellulase etc., plays a role jointly with endogenous enzymes in alimentary canal, improves feed digestibility.
Phytase: improve the content of enteron aisle phytase, stimulate the growth of phytase, improve the absorption rate of laying hen, improve the absorption of elements such as copper, iron, manganese, zinc simultaneously to the phytate phosphorus in the feed.
Complex enzyme formulation: SNSP difficulties such as xylan, beta glucan, cellulose are digested and assimilated for No. three by agricultural university, they are constituents of plant cell wall, and alimentary canal chyme viscosity is increased, cause daily ration nutrient digestibility and feeding effect to reduce, limited the application of cereal in feed.Non-starch polysaccharide enzyme such as zytase, 1,4 beta-glucanase can decompose SNSP, eliminates its anti-oxidant action.
Betaine: betaine provides active methyl efficiently for body, and a kind of mesostate as in the animal body has participated in animal protein and fat metabolism indirectly.When choline was under-supply in the feed, adding betaine had part to substitute the effect of choline.Suitable additional betaine can substitute another main methyl donor in the daily ration--the confession methyl effect of methionine, thus save methionine, improve protein utilization.Betaine provides the ability of methyl can also promote the synthetic of the interior carnitine of animal body, improves fat metabolism intensity.
Lysine: a kind of essential amino acid, easily lack in the feed, lysine has the effect of satisfying the animal needs, promoting growth of animal, improve amino acid balance, improve efficiency of feed utilization, save protein resource.Can improve the nutritive value of phytoprotein and feed thereof, help developing protein feed resource.By additionally replenishing in the feed, can make amino acid balance, improve the laying hen efficient of laying eggs.
Methionine: be a kind of requisite additive in the animal feed, it is one of base unit that constitutes in protein, be unique amino acid that contains sulphur in the essential amino acid, it participates in transfer and the metabolism of phosphorus and the synthesizing of adrenaline, choline and creatine of methyl in the body; Being the raw material of synthetic protein and cystine, is methyl donor.Particularly in the bird feed, methionine is first limiting amino acid at mixed feed.Livestock and poultry lack methionine, can cause depauperation, lose weight, and the hypodynamia of liver kidney, muscular atrophy, fur is rotten etc.
Corn protein powder: produce byproduct after starch or brewing industry are carried alcohol through medical industry, its proteinaceous nutrient composition is abundant, protein 60 %, lysine 1%, methionine 1%, digestive utilization ratio is high, and has special taste and color and luster, can be used as feed and uses, fish meal, the soya-bean cake commonly used with feed industry compare, resources advantage is obvious, and the feeding value height does not contain poisonous harmful substance, need not handle again, can directly be used as protein raw materials.
Each component of feed of the present invention matches, and as dwarf-type laying cycle of laying hens feed, can improve the particularly egg laying performance of No. three laying hens of agricultural university of dwarf-type laying hen, reduces aquaculture cost.
In order to verify the influence of the present invention to the laying hen production performance, technology department of company has carried out 150 days feeding experiment by a definite date in the 2-6 month in 2010 in raiser laying hen field.Single factor contrast test design is adopted in test, and No. three laying hens of normal agricultural university about 7800 200 ages in days are divided into test group and control group at random, and every group comprises 3 repetitions.The test group daily ration is a feed of the present invention, and the control group daily ration is common layer chicken feed.
Result of the test
Result of the test shows: 1, death rate: test group has reduced by 58.75% than control group; 2, laying rate: test group has improved 4.60% than control group; 3, average egg weight: test group has improved 2.47% than control group; 4, rate of broken eggs: test group has reduced by 13.29% than control group; 5, feedstuff-egg ratio: test group has reduced by 8.76% than control group.
