Description

A kind of high-efficiency concentration material directly supplied to chicken
Technical field
The present invention relates to a kind of feedstuff for laying hens concentrate feed, relate in particular to a kind of high-efficiency concentration material directly supplied to chicken.
Background technology
China's feed is crossed more than 20 year flourish already, has obtained the achievement that attracts people's attention, and forage yield is soaring every year, and according to statistics: by the end of the year 2005, only concentrated feed annual production in Henan Province's has reached 293.7 ten thousand tons, and total output reaches 7,820,000 tons.In the market boom, the feed market competition is also fierce further, add the outburst of the new epidemic situation of bird flu in recent years and various places and spread, the livestock and poultry livestock on hand decreases in market, the demand atrophy, cause each feed producer to demand a lower price mutually unexpectedly, with northern laying hen material market is example, same laying hen peak period concentrate feed, price difference reaches 10-15 unit/bag, the otherness of visible product quality, add that some small-sized Feed Enterprise lack qualified technical personnel, be simply equipped, cause that the feed product quality is very different in the market, had a strong impact on the performance of livestock and poultry production performance.
At present, the problem that the market laying hen exists with concentrate feed: (1) nutrient is formed complicated, and protein quality is poor, the digestion rate variance, can not satisfy the demand, feed producer is in order to reduce cost, and a large amount of assorted dregs of rice class and corn byproduct albuminoid substitutes used are as cotton dregs, the dish dregs of rice, DDG class, maize peel, corn germ cake etc., though such product crude protein can reach nutritional need, protein quality is poor, and digestibility is extremely low.(2) proportioning is unreasonable, and laying hen extremely lacks energy, concentrate feed in the market, the use proportioning mostly is: corn 60%, concentrate feed 40%, be made into complete diet pellet like this after, albumen is at 15.5-16.5%, about metabolizable energy 2580Kcl/Kg, the energy wretched insufficiency, egg can be than unreasonable.(3) technical force's difference is big between feed factory, and the product quality difference is big, some small business, and technical force is weak, the product quality management system is unsound, and constant product quality is poor.(4) raiser's products quality consciousness is thin, and when selecting product, the raiser only pays attention to feed price, outward appearance, and the product inherent quality is understood seldom.Cause the general feed intake height of laying hen (spring, autumn 125-130 gram, last month of winter 140-150 gram, indivedual even higher), the laying hen ovipository cycle is short, and death rate height, leg disease are many, and it is light to eliminate body weight, has greatly influenced the raising of culture benefit.
In addition, existing market laying hen premix also exists following problem: the product of raiser's use at present is based on 5% premix, complete diet pellet matching method: premix 5%, corn 63%, dregs of beans 24%, stone flour 8%, compare with common concentrate feed on the market, this product proportioning is more reasonable, calorie-protein level and digestibility promote to some extent, can better satisfy the nutritional need of laying hen.But it is same, also there is the deficiency of self in premix: the proportioning of (1) premix 5% takies that to join the principal space bigger, influenced the further lifting of product quality, in 5% premix, the part that 2-3% is arranged is carrier medical stone, zeolite powder class, even by pure dregs of beans type recommended formula, after being made into complete diet pellet, general crude protein is at 16.2-16.5%, and also there is certain gap in metabolizable energy with the nutritional need of laying hen about 2650Kcl/Kg.(2) the material quality variation is big, poor quality's control, and the raiser lacks raw material professional knowledge, quality discrimination ability to dregs of beans, stone flour, more impossible have the assay device of specialty that raw material is detected, and has potential safety hazard so the raw material quality is checked on, and the product quality fluctuation is big; In addition, the raw material storage condition is simple and crude, is outdoor storage as the stone flour major part, wind and weather, sneaks into a large amount of silts, and calcium content descends, and has a strong impact on eggshell quality.(3) nutriment is easily suffered a loss, is destroyed, and premix is less because of consumption, but the dealer will have some from going out the disposable delivery of cargo of producer, causes inventory time longer.By the time in raiser's hand, the trace element in the premix, Choline Chloride and salt certainly will cause certain destruction to vitamin, laying hen physique and immunologic function reduce, the chicken group is in sub-health state, and then influences the performance of production performance.
The own formula feed of the peasant household that also has, promptly fully from batching, this kind material is compared with premix with concentrate feed, can be from batching according to chicken group situation component design, can satisfy the chicken nutritional need better, but there are some defectives too in batching certainly: (1) lacks the raising poultry nutritive knowledge of specialty, the raiser prepares burden by rule of thumb, and the prescription precision is poor, and nutrition is balance not to the utmost, indivedual overnutritions, as common amino acid waste, to culture blindly and add a large amount of synthesizing amino acids, the surface sees that egg size is very big, but cause the chicken prolapse of the anus, death rate rises, and has also shortened the ovipository cycle of chicken simultaneously.(2) mixture homogeneity is poor, and raiser's production equipment is simple and easy, mostly is vertical mixer, and the operation mostly be the casual labour greatly, to incorporation time, the technology that feeds intake is not tight to check on, feed coefficient of variation height, unstable product quality, feeding effect difference is big.(3) there is hidden danger in the raw material quality, the problem that the user for preparing burden certainly equally also exists raw material to check on.(4) the big raising income of price risk is low, the general limited fund of raiser, raw material is difficult to do buying in batches, be subjected to the influence of market fluctuations in prices of raw materials, cause product cost to change greatly, add that the general cost of preparing burden certainly is higher, prescription lacks economic and practical, though seem that all day busy, the whole synthesis benefit is not high.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of high-efficiency concentration material directly supplied to chicken, to improve every nutritional need, fully to satisfy each stage physiological requirements of laying hen, improve the product digestibility and improve eggshell quality, reduction leg disease and death rate.
To achieve these goals, technical program of the present invention lies in having adopted a kind of high-efficiency concentration material directly supplied to chicken, comprise that the feedstock production of following parts by weight forms:
Middle albumen dregs of beans 62-68% expanded soybean 5.5-8.5% stone flour 22.8-25.7%
1% premix 3.7-28.5%.
Described 1% premix comprises the raw material of following parts by weight: multidimensional: 0.02%-0.025%, multi mineral trace element: 0.1%-0.12%, Choline Chloride: 0.1%-0.12%, methionine: 0.1%-0.12%, salt: 0.3%-0.35%, calcium monohydrogen phosphate: 0.35%-0.40%, enzyme preparation: 0.01%-0.012%, probiotics: 0.02%-0.025%, all the other are carrier.

Concentrate feed of the present invention is directly aimed at the raiser with the mode of direct-furnish, final is the standard of evaluation product quality with the overall economic efficiency, after concentrate feed of the present invention uses through reality, data show and have the following advantages: (1) is improved every nutritional need, is fully satisfied each stage physiological requirements of laying hen, concentrate feed of the present invention is at the drawback of conventional concentrate feed and premix in the market, structure and use proportioning to raw material have been done to reintegrate, with the laying hen material is example: setting on the basis that feed intake is 110 grams, determining the needs of other nutriment.As energy, for overcoming the general common fault on the low side of present laying hen material energy level on the market, at first forage compounding is adjusted into: corn 65%, concentrate feed 35%, simultaneously, in prescription, quote ENERGETIC MATERIALS---expanded soybean, thereby guarantee that the complete diet pellet energy level reaches more than the 2750Kcl/Kg; Equally, for satisfying the protein needs, dregs of beans is used middle albumen dregs of beans (crude protein is more than 46%) instead by common dregs of beans (crude protein 43%) in the prescription, thereby the complete diet pellet protein level is reached more than 17.2%; Other nutritive index such as calcium, phosphorus, amino acid etc. are also all taked corresponding measure adjustment, thereby have guaranteed the nutrient balance of complete diet pellet.(2) select efficient raw material for use, improve the product digestibility, introduced the easier raw material of digesting and assimilating of livestock and poultry, improved 3-5% than conventional concentrate feed on the market and premix digestibility as middle albumen dregs of beans, expanded soybean.(3) the every nutritional need of balance, improve eggshell quality, reduce leg disease and death rate, the calcium of balance, phosphorus ratio, strengthen stable vitamin and decide element with trace, simultaneously, with the theoretical prescription of introducing of electrolyte balance, the zwitterion of balance has guaranteed the eggshell quality of high-quality, and to the chicken all living creatures produce performance performance, reduce the leg disease and water incidence just plays important effect.(4) health-nutrition keeps healthy livestock and poultry in recent years, and the raiser feels that more and more difficult foster, the new epidemic situation of chicken is more and more, trace it to its cause: use medicine and vaccine, though can control disease to a certain extent, a large amount of medications make the pathogenic microorganism variation accelerate the more difficult control of eqpidemic disease; Simultaneously, make the residual increase of medicine of livestock products by antibiotic product control livestock and poultry communicable disease, and then may endanger the consumer health.One of way that solves this difficult problem is exactly: nutrition is disease-resistant.Studies show that 80% disease is relevant with immune dysfunction, and nutrition directly has influence on immune development and function, simultaneously, nutrition also influences intestinal growth and disease-resistant gene is expressed.And laying hen concentrate feed of the present invention does not add any antibiotic medicine, but by improving rational nutrition regulation, though increase chicken physique, by the performance of chicken body autoimmunity, reaches the resistance to disease.(5) use that concentrate feed of the present invention produces as the green livestock and poultry product, promote the well-being of mankind, along with growth in the living standard, people have had a lot of healthy general knowledge, and the nutrition of egg is extremely abundant, but it is more to contain cholesterol in the yolk, allows the old man who suffers from angiocardiopathy taste on tenterhooks.Studies have shown that: can regulate and control cholesterol level by scientific nutrition.Because it is bigger that the composition in the egg is influenced by feed,, can increase the content or the reduction cholesterol wherein of yolk mineral effectively by improving the prescription of feed.
Product of the present invention at first carries out the real examination of small-scale at group company's test chicken house, 1440 of 440 days healthy chickens of test selection, be divided into two groups at random: test group and control group, every group of 4 repetitions, 90 chickens of every repetition, test group adopts concentrate feed+corn of the present invention, control group is selected the full dregs of beans type of 5% premix complete diet pellet prescription (not containing fish meal) on the market for use, raise 3 days phases in advance, just trying 56 days phases, test bit sees the following form.The result shows, compares with control group, and laying rate has improved 2.43%, and egg size difference is not remarkable, but feed intake has reduced by 6.89%, and feedstuff-egg ratio has reduced by 8.33%, and an average egg yield has improved 2.82%, significant difference.
Figure A20071005382900061
The present invention has selected also that representational large-scale plant carries out pilot scale on the market, choose laid eggs in 260 days 10000 of peak chickens and 340 days 25000 of laying hens of Gongyi City plant of Xinmi City plant respectively and compare test, through raising checking in 42 days, the result is consistent to be reflected: laying rate can increase 1-3%; About feed intake 110 gram, feedstuff-egg ratio 2.1-2.2, and compared obvious decline before the test, the ratio that descends by statistics is more than 5%.
Properties of product of the present invention are compared with the obvious advantage with common concentrate feed and premix, autumn and winter season, and feed intake 110-115 gram, feedstuff-egg ratio 2.1-2.3, feed efficiency improves, and culture benefit obviously increases.
Three kinds of production of fodder performances and economic efficiency contrast
Figure A20071005382900071
As can be seen from the above table, use product of the present invention, compare with premix, 1000 kilograms of eggs of every production can increase by 300 yuan of benefits, compare with common concentrate feed, can increase by 230 yuan of benefits.
With ten thousand the laying hen statistics in Xinmi City is example: feedstuff-egg ratio drops to 2.2 by 2.3, amplitude: 4.3%; Feed intake is saved feed by dropping to 2.2,10000 chickens 2.3 liang of incipient every days: 100 jin/every day; Egg production: 10000 chickens are improved 6 jin every day.
Increase income every day: 100 jin * 0.80 yuan/jin=80 yuan
Egg production: 6 jin * 2.7 yuan/jin=16.2 yuan
Increased income (80+16.2) * 30 day/month=2886 yuan in every month
Can see from above statistics: ten thousand chicken houses can increase benefit 2886 * 12=34632 unit every year.
Experiment showed, and use product of the present invention, laying rate has improved 2.43%, and egg size difference is not remarkable, but feed intake has reduced by 6.89%, and feedstuff-egg ratio has reduced by 8.33%, and an average egg yield has improved 2.82%, significant difference.Ten thousand chicken houses can increase benefit 2886 * 12=34632 unit every year.In addition, the egg eggs ' quality is better, safer.
