        長毛兔養殖新技術

        發布日期:2020-05-28 來源:http://m.51haodu.com 發布人:admin

        目前長毛兔的兔毛產品更加傾向于往紡高支紗、做輕薄產品這個方向。一方面符合服裝向輕薄化發展的潮流,另外也易于解決原兔毛產品存在的掉毛、起球、縮水三大難題,因此對細度的要求較高。長毛兔的養毛期要根據毛紡市場的需求靈活掌握。
        At present, the rabbit hair products of long wool rabbit are more inclined to spinning high count yarn and making light and thin products. On the one hand, it is in line with the trend of the development of light and thin clothing. On the other hand, it is easy to solve the three problems existing in the original rabbit hair products, namely, shedding, pilling and shrinkage. Therefore, it requires high fineness. The raising period of long wool rabbit should be controlled flexibly according to the demand of wool market.
        長毛兔
        山東省蒙陰鑫華種兔場對不同養毛期兔毛生長速度和纖維細度進行測定,實際生產中可根據各地不同的氣候特點及市場需求,適當調整養毛期,晚春早夏季節,采用50~70天的養毛期,兔毛可達到紡織要求。
        The growth speed and fiber fineness of rabbit hair in different raising periods were measured in Xinhua rabbit farm of Mengyin, Shandong Province. In actual production, according to different climatic characteristics and market demand, the raising period can be adjusted appropriately. From late spring to early summer, the raising period of 50-70 days is adopted, and the rabbit hair can meet the textile requirements.
        目前在生產過程中使用的大宗飼料原料主要為玉米、餅粕類、農作物秸稈和部分工業副產品等,隨著工業用玉米用量的增加和畜牧業發展對飼料原料需求的增加,養殖業面臨飼料上漲、飼料來源緊張和飼料質量難以控制的問題,特別是粗飼料,很難滿足長毛兔生產的需要,因此,必須開發非常規飼料。
        At present, the bulk feed raw materials used in the production process are mainly corn, cake, crop straw and some industrial by-products. With the increase of industrial corn consumption and the increase of demand for feed raw materials in the development of animal husbandry, the breeding industry is facing the problems of rising feed price, shortage of feed sources and difficult to control feed quality, especially the coarse feed, which is difficult to meet the long haired rabbit Therefore, it is necessary to develop unconventional feed.
        食用菌渣為食用菌產菇后的廢料,食用菌栽培原料經微生物發酵后,部分物質被降解,可適當添加用作畜禽飼料。比如金針菇菌渣與小麥麩皮相比,粗蛋白略低,粗纖維含量接近,但菌渣為有益菌發酵產品,含有更多的菌體蛋白和非蛋白氮,更適宜兔的消化和利用,可完全替代小麥麩皮。
        The residue of edible mushroom is the waste after the production of edible mushroom. After the fermentation of the raw material of edible mushroom, part of the material is degraded and can be properly added as animal feed. For example, compared with wheat bran, the crude protein of Flammulina velutipes dregs is slightly lower and the crude fiber content is similar, but the dregs are beneficial fermentation products, containing more bacterial protein and non protein nitrogen, which are more suitable for the digestion and utilization of rabbits and can completely replace wheat bran.
        長毛兔剪毛方法的改進是將傳統的剪毛方法加以改進,該方法剪毛速度會更快。利用這種方法,熟練剪毛工每只兔的剪毛時間可節省3~5分鐘,既可提高勞動效率,又可提高兔毛的質量。
        The improvement of long wool rabbit's shearing method is to improve the traditional shearing method, which will cut faster. By using this method, skilled shearers can save 3-5 minutes of shearing time for each rabbit, which can not only improve labor efficiency, but also improve the quality of rabbit hair.
