Description
Technical field
The present invention relates to contain the animal-breeding feed that derives from plant, animal or raw mineral materials, particularly a kind of fleshy duck fodder that contains DDGS and preparation method thereof.
Background technology
In recent years, because the world food shortage causes supply of forage day to be becoming tight, it is apparent that especially the deflation of high protein feed resource exceedes invention.Therefore, how other unconventional protein resource of development and utilization just becomes the focus that the researcher more and more pays close attention to.Discover, because alcohol is poor and the dry thing of raffinate (distillers dried grains with solubles, DDGS) protein content height, nutritive value are complete, and output is big, cheap, security is good, can be used as the feedstuff of various domestic animal Cheap highly effectives, in aquaculture, obtained extensive studies in recent years.
DDGS (maize alcohol stillage and DDGS thereof) mainly is meant the symbiosis product that forms through low temperature drying with the remaining ferment residue behind corn seed and selected yeast for fermentation production alcohol fuel and the carbon dioxide, it is to have concentrated the mixture of other nutritional labelings (as albumen, fat, vitamin etc.) except starch and sugar in the corn, it comprises DDS (solvable dry alcohol groove, Distillers Dried Solubles) and DDG (dry alcohol groove, Distillers Dried Grains) two parts.Therefore, its nutritive value compare with former corn kernel have low starch, high protein, height can digest many characteristics such as fiber and high effective phosphorus.
DDGS has kept the nutritional labelings such as protein of former cereal to greatest extent, has increased significantly than former cereal on the quality.DDGS is the high-quality protein raw material, its amino acid content and can digest amino acid content, protein all than higher about 28%, lysine 1.3%, methionine 0.6%.Protein occupies special status in Animal nutrition, its trophism is that other nutriments are irreplaceable.
The fat content of DDGS is higher, generally can reach 9%～13%, and moisture is lower than 11%, have advantages such as long preservation is not gone mouldy, high temperature does not become sour, and all kinds of fatty acid proportions is suitable in the fat, and good adaptability is arranged.Linoleic acid content is higher among the DDGS, can reach 2.3%, is the good source of essential fatty acids linoleic.
DDGS during the fermentation, bacterium has been decomposed the part cellulose, has destroyed the tight structure between cellulose and the lignin simultaneously, and the utilization rate of its fibre composition is improved, and has improved its biological value.The fibrous substance content of DDGS is relevant with its quality, is generally 7.1%-8.0%.
Practitioner such as Guo Liang, Guo Hao or scholar discover, nonprotein nitrogen and the phosphorus content of DDGS are higher, and its phosphorus content is 0.94%-1.21%, and calcium is 0.2% ~ 0.4%.Shurson (2002) is reported in and adds the consumption that DDGS can save calcium monohydrogen phosphate in the daily ration, thereby reduces feed cost.
Contain a large amount of yeast thalline among the DDGS, B family vitamin content is abundant.In addition, the UGF that produces in the fermentation, saccharide, yeast etc. are very favourable to growth of animal.
Owing to incorporated the nutritional labeling and the active factors of saccharification song and yeast among the DDGS, thereby it is the high-quality protein feed raw material of a kind of high protein, high nutrition, no any ANFs.
The appearance color of DDGS wherein, is saffron its smell and nutrient better performances from the crocus to the peony.It is because the difference of its lysine level that contains causes that DDGS presents various luster.DDGS is the good source of protein, fat, vitamin and mineral matter, and contains UGF.The main feature of corn DDGS feed is that low starch, high protein, height can digest fiber and high effective phosphorus, and it can be widely used in during herding produces.
Only rest on aspect to the digestion of ox, pig for DDGS mostly in the research aspect the feed, what be used for that poultry studies is less.This has influenced the application of DDGS in poultry production to a certain extent.For poultry, DDGS is poultry first limiting amino acid--the fine source of methionine also is the fine source of poultry essential fatty acid simultaneously.The evaluation definite and feed nutritive value of poultry protein requirement all will be considered the level of essential amino acid in the daily ration, each seed amino acid all will balance each other with the needs of the best level of production of feeding animal in quantity and ratio in the diet, guarantee effective utilization of essential amino acid, improve the conversion ratio of diet protein.And DDGS produces the later product of wine through culture propagation, and it has passed through the conversion process of vegetable protein to microprotein, thereby the protein of DDGS has more the quality that is fit to the Animal nutrition needs.The higher fatty acid characteristic of DDGS concerning poultry also tool have very important significance, it not only can offer the enough essential fatty acids of poultry, and can satisfy poultry early growth and the egg-laying peak needs to energy as anakinetomer.Zhang Yanming, Zhen Erying etc. find in the alternative dregs of beans of forming with DDGS and rapeseed dregs is fed the experimental study of laying hen: compare with control group, the chicken body weight of the DDGS mixed feed group of feeding increases by 0.22%, 3.5% and 0.84% respectively; Laying rate improves 3.7%, 1.9% and 1.3% respectively; Daily material consumption reduces by 3.3%, 4.8% and 3.9% respectively; Feedstuff-egg ratio reduces by 3.3%, 3.8% and 3.3% respectively.
DDGS also is the source of poultry essential fatty acids linoleic, and linoleic acid is the essential fatty acid of poultry, participates in the synthetic and metabolism of fat, and energy is in liberal supply, helps the protein metabolism in the poultry body, thereby increases egg size; Energy is under-supply, and egg production descends.Therefore, DDGS cooperates the feed that can become kind of chicken and laying hen with other feeds.Li Hengxin is worth the conventional nutrient crude protein, crude fat, crude fibre, calcium, the phosphorus content that record DDGS in the evaluation at laying hen nutrition and is respectively 40.00%, 8.60%, 7.45%, 0.10%, wherein, crude fibre and crude fat content are a little more than dregs of beans, all the other nutrient contents and dregs of beans are suitable, studies show that DDGS can partly replace dregs of beans to be used among the laying hen production; Shurson (2002) is reported in and adds the consumption that DDGS can save calcium monohydrogen phosphate in the daily ration, simultaneously, another that is undertaken by Nick doctor Dale of University of Minnesota and other researchers studies show that, nutrient that DDGS contains and digestibility make it can be used as effective constitutive material in the poultry diet.
In the U.S., producer is on the increase along with fuel ethanol production, has every year a large amount of DDGS products to infeed domestic market and international market.According to the up-to-date report of fuel association, the DDGS that the U.S. produced in 2006 amounts up to 8,500,000 t, estimates that 2010 annual productions can be increased to 3 600 ten thousand t.Therefore, be applied in the animal and fowl fodder with being expected to greater amount.In China's ethanol industry long history is arranged, the eighties in 20th century is because the increasing sharply of China's corn yield, and causing with the corn is that the producer that raw material is produced ethanol develops rapidly.Simultaneously because corn ethanol coproduction DDGS as the enforcement of an industrial policy, has reached about 50% from the total ethanol output of maize raw material, therefore annual have a large amount of corn DDGS symbiosis products to produce.
Along with constantly skyrocketing of conventional cost of material instantly, break through conventional, attempt using unconventional quality raw materials for being engaged in the each side of culturing industry, be the behave of a win-win.
