Abstract

A production technology of straw coarse fodder for Hu-sheep is characterized by including the following steps that firstly, straw is cut into segments which are 10-20 cm long by means of a hay cutter, and then the straw segments are rubbed into strip shapes, continuously added into a saline solution, stacked on a cement ground and covered by a plastic film so that air tightness can be achieved for fermentation; secondly, the fermented straw is smashed into small segments which are 2-3 cm long and placed into an ammoniation pond, urea is dissolved with warm water to form a solution, the prepared urea solution is evenly sprayed on the straw, after the straw is laid in the ammoniation pond, the pond opening is covered by a plastic film, fermentation is conducted for 20-30 days, and the straw coarse fodder can be prepared. By means of the simple process, crop straw is prepared into the coarse fodder for Hu-sheep, the nutritional level of the coarse fodder is improved through ammoniation treatment, the content of crude protein is increased to 100-150%, the content of cellulose is reduced by about 10%, and meanwhile the digestion rate of Hu-sheep is increased by about 20%.

Description

A kind of production technology of sheep stalk coarse fodder

Technical field

The present invention relates to the production technology of a kind of feedstuff, be specifically related to a kind of sheep stalk coarse fodder Production technology.

Background technology

China is a large agricultural country, and crop specie enriches, and mainly includes cereal crops warp Ji crop (oil crop, vegetable crop, flowers and plants, fruit and hobby crop etc.), industry Crop, forage crop, medical material etc..According to the generally understanding of current people, so-called agriculture Crop material is the general name of ripe crops stem and leaf (fringe) part, it is common that refer to that crops are being received Obtaining the remainder after seed, its average product is typically about more than 1 to 2 times of seed.According to This, the agricultural crop straw of broad sense refers to the various plants agriculturally cultivated remaining after results seed Remaining part is divided, and the agricultural crop straw of relative narrow sense is primarily referred to as cereal crops, industrial crops and work Industry crop remainder after results seed and the whole plant of forage crop whole. Agricultural crop straw is a kind of Organic substance, and wherein carbon, oxygen, three kinds of chemical composition summations of hydrogen account for 95% Above, remaining is the mineral elements such as potassium, nitrogen, phosphorus, silicon, calcium, magnesium, sulfur, but content is relatively Low；Organic principle based on cellulose, hemicellulose, secondly be lignin, protein, Fat, ash.Cellulose in agricultural crop straw, hemicellulose are combined closely with lignin, phase It is wound around mutually and constitutes crude fibre, be the main component of plant cell wall.

Agricultural crop straw is produced in the whole production process of animal feeding-stuff can be effectively improved fermentation The key link that product nutrient is worth is: pretreatment, the degraded of cellulose, white microorganism of laying eggs Application and the control of sweat conditional to saccharide.For pretreatment, the most in practice Be difficult to find effective, be easy to a large amount of production practices method that cost is the lowest simultaneously；For process Middle cellulose and hemicellulose, on the one hand its degraded is affected by pretreating effect, another Aspect is affected by microorganism itself and fermentation.At present about in agricultural crop straw The degradation effect of cellulose and hemicellulose is the most undesirable, further limit agricultural crop straw and makees Application for domestic animal, especially feedstuff for hu yang.

Summary of the invention

For the deficiencies in the prior art, the invention provides the production of a kind of sheep stalk coarse fodder Technique.

The present invention can be achieved through the following technical solutions:

A kind of production technology of sheep stalk coarse fodder, its processing step is as follows:

(1) with hay cutter, straw is cut up with a hay cutter into the section of 10-20cm, then through rubbing filamentation strip, Continuously adding the saline solution that content is 1%, the amount of saline solution is just flooded straw, is then stacked On cement flooring, building with plastic sheeting so that it is stuffy, ferment 10-15d；

(2) segment that the powder of straw after fermentation is broken into 2-3cm is put in ammonification pond, then The carbamide warm water accounting for straw weight 4%-6% dissolves formation solution, molten for the carbamide prepared Liquid is sprayed on straw uniformly, and sprinkling limit, limit is stirred, after being paved with ammonification pond, thin with plastics Film is good pond lid, allows ammonification pond be in sealing state, and fermentation time is 20-30d；Described add The amount of the warm water entered is 10 times of weight of urea.

Further, bottom fragment of brick or the stone in the ammonification pond described in step 2 are completed, then Building last layer cement, the surrounding in ammonification pond is coated one layer of polyurethane foam and is incubated.

The present invention obtain have the beneficial effect that this method by simple technique, by crops straw Stalk is prepared as sheep roughage, and by the trophic level of ammoniated treatment raising roughage, slightly The content of albumen increases 100%-150%, and the content of cellulose reduces about 10%, lake simultaneously The digestibility of sheep improves about 20%；Surrounding in ammonification pond add polyurethane foam, can in case When only temperature is too low, straw freezes, and is unfavorable for feeding in winter, and temperature is too low simultaneously can affect straw The fermentation of stalk.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is further illustrated.

Embodiment

The production technology of a kind of sheep stalk coarse fodder, its processing step is as follows: (1) is careless with hand hay cutter Straw is cut up with a hay cutter into the section of 10cm by machine, then through rubbing filamentation strip, continuously adding content is 1% Saline solution, the amount of saline solution is just flooded straw, is then deposited on cement flooring, with moulding Material thin film is built so that it is stuffy, and ferment 15d；(2) by the straw after 10 weight portion fermentations Stalk is ground into the segment of 2cm and puts in ammonification pond, the bottom fragment of brick in ammonification pond or stone paving Good, then build last layer cement, the surrounding in ammonification pond is coated one layer of polyurethane foam and is incubated, Again the carbamide of 0.5 weight portion is dissolved formation solution with 5 weight portion warm water, the urine prepared Cellulose solution is sprayed on straw uniformly, and sprinkling limit, limit is stirred, after being paved with ammonification pond, with moulding Material thin film is good pond lid, allows ammonification pond be in sealing state, and fermentation time is 20d, Prepare stalk coarse fodder.

Agricultural crop straw, by simple technique, is prepared as sheep roughage by this method, and Improved the trophic level of roughage by ammoniated treatment, the content of crude protein increases by 120%, fibre The content of dimension element reduces 10%, and the digestibility of sheep improves 20% simultaneously, winter temperature mistake simultaneously Time low, feeding and fermentation are the most unaffected.

The foregoing is only the section Example of the present invention, not in order to limit the present invention, All any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, Should be included within the scope of the present invention.
