The various departments of the brothers and sisters have set up the department of animal husbandry in the biology teaching field successively, and the achievements made are remarkable. The most common animals are rabbits because raising rabbits has many advantages: (i) rabbits Is a good experimental material for teaching and scientific research. (B) the cost of raising rabbits low; high product value, large profits. (C) adequate supply of rabbit feed, can make full use of agricultural and sideline products.
