Production technology of straw coarse fodder for Hu-sheep

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

technical field [0001] The invention relates to a production process of feed, in particular to a production process of Hu sheep straw roughage. Background technique [0002] my country is a large agricultural country with a rich variety of crops, mainly including food crops, economic crops (oil crops, vegetable crops, flowers, fruits, and hobby crops, etc.), industrial raw material crops, feed crops, medicinal materials, etc. According to the general understanding of people at present, the so-called crop stalks are the general term for the stems and leaves (ears) of mature crops, and usually refer to the remaining parts of the crops after the seeds are harvested, and the average yield is generally about 1 to 2 times that of the seeds. Accordingly, crop straw in a broad sense refers to the remaining parts of various plants cultivated in agriculture after harvesting seeds, while crop straw in a relatively narrow sense mainly refers to the remaining parts of food crops, economi...

Problems solved by technology

For pretreatment, it is difficult to find a method with good effect, convenient mass production practice and low cost in practice; for cellulose and hemicellulose in the process, on the one hand, its degradation is affected by the effect of pretreatment, on the other hand Affected by the microorganism itself and the control of fermentation conditions

At present, the degradation effect of cellulose and hemicellulose in crop straws is still not ideal, which further limits the application of crop straws as feed for livestock, especially Hu sheep.
