Description
Technical field
The utility model relates to biofermentation change system field, more particularly, relates to a kind of preparation system of feed.
Background technology
Along with the increase of population and income, Chinese residents eating patterns are greatly improved, very fast to the demand growth of edible livestock products, and therefore, the rapid growth of the consumption figure of the animal foodstuffs such as meat, egg, milk must drive feed demand amount to rise.How more rationally, effectively and meanwhile, the cultivated land resource of China constantly reduces, native pasture constantly disappears, utilize existing precious resources to seem especially important.
Feed is made with stalk by China very long history, and agricultural crop straw mainly comprises wheat straw, straw, corn stalk, sorghum straw and beanstalk etc.For the stalk of feed stripped, dissimilar its nutritional labeling has very large difference, but all stalks all have following common feature: the crude protein content of stalk is very low, is only 2%～5% left and right; Crude fiber content is high, is 20%～45% left and right; The mineral matter of stalk, as very low in the content of calcium, phosphorus, and uneven; Palatability is poor, and livestock feed intake is extremely low.But stalk is after rationally processing of physics, chemistry and the microbe fermentation method technical finesses such as ensiling, micro-storage and ammonification, can improve feed intake, nutritive value and digestibility, feed Livestock or as the basal diet of preparing complete feed, has significant effect to the growth of Livestock and weightening finish, the raising price of deed and economic benefit.
The existing many reports of research of processing feedstuff with stalks, but because the structure that in stalk, cellulose, hemicellulose and lignin are interweaved forms stable macromolecular compound, can not be decomposed and depend merely on by fowl poultry kind pipe intestinal digesting the metabolism of microorganism, the improvement of nutritive value is also very limited.Lay particular emphasis at present the mode Treating straws such as the ensiling of small-scale production, micro-storage, ammonification more, that can not effectively realize these affluent resources of agricultural crop straw is converted into the high nutrition straw feed of high-quality, and considerably less to being suitable for the straw feedization research that the steam explosive-crushing of industrialization processes.Patent (99122346.2) discloses a kind of method that mixed solid fermentation and straw puffing is prepared protein feed, comprise the following steps: stalk steam explosive-crushing is processed, vapour discloses that by formula, making culture medium for fermentation, sterilizing access fermented bacterium, tray solid state fermentation, oven dry obtains protein feed, wherein: fermentation is the mixture of steam puffed stalk and wheat bran and inorganic salt solution with culture medium, the bacterial classification that fermentation adopts is the mixture of penicillium decumbens, Phanerochaete chrysosporium and candida tropicalis.The method fermentation time is short, and stalk is converted into protein feed potentiality and does not give full play to.The agricultural crop straw that utilizes that patent (99122346.2) discloses based on the quick-fried technology of vapour is prepared the method for high nutritive value feed, first agricultural crop straw is pulverized, again the agricultural crop straw after pulverizing is carried out to Chemical Pretreatment, then the stalk after Chemical Pretreatment is packed in steam blasting device, pass into saturated vapor, dimension after pressing certain hour is produced stalk, to reach, destroys its lignocellulosic structure, improves crops straw stalk feed nutritive value and the object that realizes safe without toxic side effect.The method need to be added chemical reagent urea and Ca (OH)
2carry out ammonification processing, the urase content of stalk is extremely low, and being difficult to urea decomposition is ammonia, lower to the utilization rate of ammonia during therefore with urea ammoniated, remaining ammonia is put into air after opening ammonification facility, has caused certain pollution, and the health of domestic animal and human body is had to certain harm.
Feather is the cornified derivative of bird epidermal cell, percentage of liveweight 5% ~ 11%.Feather bar and leftover bits and pieces thereof are the byproducts of butchering fowl processing or down products.According to statistics, China can collect approximately 20 ~ 300,000 tons, the feather bar leftover bits and pieces of utilization every year, and after processing, for 20,000 tons of the deficiencies of feed, most of feather and animal hair are not used appropriately.Its main cause is that feather meal process technology does not pass a test, and product digestibility is low, and quality is uneven, causes feeding effect not good.In feather, protein content 75% ~ 90%, and sulfur-containing amino acid (cystine Cys etc.) reaches 9% ~ 11%.Because feather protein belongs to keratoprotein, must process keratin, crack the space structure of keratoprotein, make it become the state that can digest and assimilate.At present, the method that the feather meal processing enterprise of China generally adopts has high-temperature high-pressure hydrolysis, acid (alkali) Hydrolyze method, enzymatic isolation method, microbe fermentation method and expanded method.The shortcoming of high-temperature high-pressure hydrolysis is that power consumption of polymer processing is high, large to heat sensitive loss of proteins amount.Acid (alkali) Hydrolyze method environmental pollution is serious, and product salinity is higher, affects palatability.Enzymatic isolation method and microbe fermentation method need to, by feather pulverizing in advance, increase mechanical energy consumption conventionally.Expanded method, because investment is large, cost is high, production efficiency is low, fails to be applied in China.
