First, provide a reasonable basis for the diet
The basal diet is a diet that is necessary to maintain the growth and physiological activity of long-haired rabbits. Hair producing rabbits generally require energy of 10.37 MJ/kg, crude protein 16%, calcium 0.4%, phosphorus 0.21%, crude fiber 11.27%, lysine 0.62%, and methionine 0.58%. The feed formulation was as follows: peanut meal 39.8%, bean cake 16.0%, cornmeal 26.5%, wheat bran 12%, imported fishmeal 3%, bone meal 2.0%, methionine 0.2%, table salt 0.5%.
Second, scientific feeding and management
Feeding management is also very important to increase wool production. To maintain the cleanliness of the rabbithouse, clean the rabbit cage once a day. Keep warm in winter and heatstroke in summer. The best temperature is 15-20°C.
III. Addition of amino acids and individual trace elements
Sulfur amino acids in rabbit hair are 15%, and the sulfur-containing amino acids in diets are generally not sufficient for high hair production. Therefore, adding 0.7% methionine to the diet can increase wool production by 20%. The individual trace elements in the full-price compound feed can still not meet the needs of rabbits with high-yielding hair. Therefore, adding appropriate amounts of copper, iron, and zinc in the diet can promote the formation of keratinized proteins and increase the amount of wool produced. According to research, adding 30 mg of copper, 20 mg of iron and 10 mg of zinc per kilogram of diet can increase wool production by 27%, and add 0.2% of sodium sulfate to stimulate the gastrointestinal mucosa, which can play a certain stomachic effect. And can supplement the sulfur content in the feed.
Fourth, timely shearing
Although the hair price was high on the 90th, the rabbit hair growth was extremely slow after 70 days. In summer, it is possible to cut hair 50 days in the morning, and 70 days in winter. This makes full use of the advantages of rapid growth after shearing, and increases shearing once a year. According to the study, 70 days of shearing can increase the gross output by 70% compared to 90 days of shearing.
