Abstract
The invention relates to an activated enzyme straw feed and a preparation method thereof. According to the feed, composite strains are optimized and combined by microbial fermentation technology, and a variety of crop straws and other agricultural and sideline products are fermented to produce pellet feed. In the invention, the crop straws are fully utilized, the quality of the feed is perfected by the fermentation of mixed microbial fermentation bacteria to greatly improve the nutritive value and utilization rate of the raw materials, and the palatability of the straw feed is perfected by fermentation to improve the feed intake and daily gain of livestock.
Description
Technical field
The invention belongs to fermented feed technical field, be specifically related to a kind of straw feed and preparation method thereof, particularly relate to a kind of activating enzyme straw feed and preparation method thereof.
Background technology
The stalk resource of China is very abundant, and annual production can reach 5.79 hundred million tons.Wherein, the large crop material output of corn, wheat and rice straw three reaches 4.39 hundred million tons, accounts for 75.88% of whole stalk output.At present, along with the fast development of animal husbandry, exacerbate the dependence of animal husbandry to grain, but stalk be used as feed negligible amounts, even if be used as feed also because processing and utilization is improper, make the utilization rate of stalk and price of deed rate low.Agricultural crop straw is of low nutritive value, palatability is poor, digestibility is low.If reasonably process adjustment to it, can be used for domestic animal of feeding.It is reported, stalk is after the medical treatment of the method such as ensiling, ammonification, and every 6kg ensiling stalks or 4kg ammoniated straw are equivalent to the nutritive value of 1kg corn feed.Therefore, adopt the method for science to carry out processing to stalk and adjust, be widely used in animal husbandry, there is good ecological benefits Social benefit and economic benefit.
The application technology of crop straws for producing feed is utilized mainly to there is following problem at present:
(1) only adopt physical treatment method, to stalk carry out simple physical treatment or to stalk carry out hand hay cutter short or pulverize, the nutritional labeling of stalk can not be made to have greatly changed and improve;
(2) only chemical method is adopted, as used mirabilite, the plaster of paris, urea, salt, sugar, potassium permanganate, formic acid etc., simple chemical treatment is done to stalk, change little to the nutritional labeling of stalk, also have certain side effect, and certain pollution is caused to environment;
(3) by adding complicated trace element and enzyme preparation, its production cost is higher, is not easy to apply in rural area;
(4) adopt edible mushroom to carry out decomposition and inversion to stalk, the cycle of its decomposition and inversion is longer, and the long general time needing more than one month, production efficiency is lower;
(5) use microbial decomposition composite bacterium powder, fermented stalk produces feed, but needs specialized factory for producing composite bacterium powder specially, is not easy to apply at rural area popularity.
Due in recent years China promote ammoniated forage, not only cost is high, energy consumption is high, and exist with agricultural strive fertilizer, contaminated environment, some method is for livestock also toxic side effect.And adopt microorganism fungus kind fermented stalk feed to have the advantages such as easy to operate, environmentally safe, but at present spoilage organisms, control secondary fermentation are suppressed for comprehensive solution in feed fermentation process, effective control organic acid and lignocellulose degradation, reduce costs, the aspect such as easy to use still has problems.
