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.
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.
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.
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.
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.
