What are the main aspects of the current situation of breeding long haired rabbits?
1. Breeding of rabbit breeds. (1) Market demand for rabbits. At present, spinning high count yarn and making light and thin products are the direction for rabbit hair products. On the one hand, it is in line with the trend of clothing towards lightweight development, and on the other hand, it is easy to solve the three major problems of hair loss, pilling, and shrinkage in original rabbit hair products. Therefore, the requirement for fineness is high.
(2) Cultivate rabbit hair varieties suitable for the market. Through research, it has been found that the fine hair of the currently cultivated long haired rabbits is relatively coarse, mostly ranging from 16 to 17 microns. Therefore, the focus of rabbit breeding should not be solely on improving production, but should be comprehensively considered according to the needs of the product. The requirement for hair length is lower than fineness. Rabbit hair with a hair length of 3-4 centimeters can meet the spinning requirements, while rabbit hair with a hair length of about 2 centimeters can be used for blending with cotton.
2. Determination of hair raising period. The wool raising period of long haired rabbits should be flexibly controlled according to the needs of the wool textile market. Guoyong Farm measured the growth rate and fiber fineness of rabbit hair during different hair raising periods, and the results showed that the growth rate of rabbit hair in the early stage (1-20 days) exceeded 1 mm/day, but gradually slowed down in the future. During the 50 day hair raising period, the length of rabbit hair can reach 35 millimeters, approaching 40 millimeters in 60 days, and 50 millimeters in back hair in 70 days. In actual production, the wool raising period can be adjusted appropriately according to the different climate characteristics and market demands in different regions. From late spring to early summer, a wool raising period of 50-70 days can be used, and rabbit hair can meet the textile requirements.
3. Current situation of feed. At present, the main bulk feed raw materials used in the production process are corn, cake, crop straw, and some industrial by-products. With the increase in the amount of industrial corn and the increasing demand for feed raw materials in the development of animal husbandry, the breeding industry is facing problems such as rising feed prices, tight feed sources, and difficult to control feed quality, especially rough feed, which is difficult to meet the needs of rabbit production. Therefore, It is necessary to develop unconventional feed.
(1) Edible mushroom residue. Mushroom residue is the waste produced by edible mushrooms. After microbial fermentation, some substances in the cultivation materials of edible mushrooms are degraded and can be appropriately added for livestock and poultry feed. Adding 10% to 15% to rabbit feed can reduce feed costs without affecting production performance. For example, compared to wheat bran, mushroom residue has slightly lower crude protein and similar crude fiber content. However, mushroom residue is a beneficial fermented product that contains more bacterial protein and non protein nitrogen, making it more suitable for digestion and utilization by rabbits and can completely replace wheat bran. However, due to the high moisture content of fresh bacterial residue of over 40%, it is necessary to quickly dry or dry the fresh bacterial residue in good weather conditions during production to reduce mold formation, which limits the development and utilization of fresh bacterial residue. When adding bacterial residue, appropriate mold removal agents can be added.
(2) Apple meal. Apple meal is a pure natural and green feed made from high-quality and fresh apples, selected, cleaned, pressed, dried, and crushed. Small rabbit feed can be added with 5% to 8%, while large rabbit feed can be added with 10% to 20%.
(3) Pine needle powder. Pine needle powder is made from the needles of tree species such as Pinus massoniana through a series of processing techniques. Adding 5% to rabbit feed can significantly increase wool density and increase wool yield by about 10%.
