Four ways of raising long-haired rabbits to increase their hair
1. Provide reasonable basic diet
The basic diet is necessary to maintain the growth and physiological activities of long-haired rabbits. Wool rabbits generally require 10.37 megajoules / kg of energy, 16% of crude protein, 0.4% of calcium, 0.21% of phosphorus, 11.27% of crude fiber, 0.62% of lysine and 0.58% of methionine. The feed formula is as follows: peanut rice meal 39.8%, bean cake 16.0%, corn flour 26.5%, wheat bran 12%, imported fish meal 3%, bone meal 2.0%, methionine 0.2%, salt 0.5%.
2. Scientific feeding and management
Feeding and management is also very important to increase wool production. To keep the rabbit house clean and clean, clean the rabbit cage once a day. Pay attention to heat preservation in winter and prevent heat in summer. The best temperature is 15: 20 ℃.
Third, skillfully add amino acids and individual trace elements
The content of sulfur amino acids in rabbit hair is 15%, and the sulfur amino acids in the diet can not meet the needs of high-yield wool, so adding 0.7% methionine to the diet can increase wool yield by 20%. A few trace elements in the full-price formula feed still can not meet the needs of high-yield hair of rabbits, so adding appropriate amount of copper, iron and zinc to the diet can promote the formation of keratinized protein and increase wool yield. According to the study, 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% sodium sulfate to stimulate gastrointestinal mucosa. it can play a certain role in invigorating the stomach and replenishing the content of sulfur in the feed.
4. Timely shearing
Although the wool price of 90-day shearing is high, the growth of rabbit hair is very slow after 70 days. Shearing can be as early as 50 days in summer and 70 days in winter, which makes full use of the advantage of fast growth after shearing and can increase shearing once a year. According to research, 70-day shearing can increase wool yield by about 70% compared with 90-day shearing.

The diet should be skillfully matched with low-energy and high-protein full-price feed for rabbits in summer, and it should be reasonably matched with concentrate, green concentrate and coarse feed, and the crude fiber should be controlled at 12%-14%. Try to choose green feed with less moisture. Properly feed plantain, Artemisia annua, purslane, garlic and leek
