在实际生产中，维生素添加剂的配合形式多采用多维添加剂。因日粮中添加量很少，必须经扩大预配后再行添加，以免混合不匀，造成浪费，达不到添加的目的。

　　In actual production, multidimensional additives are used in the combination of vitamin additives. Because the addition of the diet is very small, it must be added after the expansion of the pre - added, so as to avoid the unevenness of mixing, resulting in waste, and can not reach the purpose of adding.

　　1.维生素E为无色晶体，在光照、空气中极易氧化破坏。维生素E具有维持正常繁殖机能和维持肌肉及外周血管系统的正常功能，增强免疫反应和与硒有协同作用等。

　　1. vitamin E is a colorless crystal, which is easily oxidized in light and air. Vitamin E has the normal function of maintaining normal reproductive function, maintaining the normal function of the muscle and peripheral vascular system, enhancing the immune response and synergistic effect with selenium.

　　长毛兔缺乏时会引起生殖器官萎缩、衰退，机能失调而影响繁殖力。在种兔日粮中添加高水平维生素E，能明显提高产仔数和断奶育成数;当兔群感染肝球虫病时，添加高水平维生素E,疗效显著。

　　The deficiency can cause the reproductive organs to atrophy, decline, and affect the fecundity. With high levels of vitamin E in rabbit diets can significantly improve the litter size and the number of weaned bred; when the rabbit liver coccidiosis infection group, with high levels of vitamin E, curative effect.

　　2.维生素A维生素A为黄色结晶体，在光照、空气中极易氧化破坏。维生素A具有维持上皮组织和神经组织的正常功能，缺乏时会影响长毛兔的正常生长发育和繁殖功能，降低抗感染能力，增加眼病和呼吸道疾病的发病率。

　　2. vitamin A vitamin A is a yellow crystal, and it is very easy to oxidize in light and air. Vitamin A has the normal function of maintaining epithelial tissue and nerve tissue. When lacking, it will affect the normal growth and reproduction function of long haired rabbits, reduce the ability of anti infection, and increase the incidence of eye diseases and respiratory diseases.

　　在免疫接种、某些病原菌感染或球虫病期，补充适量维生素A，对增强长毛兔的抗病力和病后恢复及抗体产生水平均有良好效果。

　　Supplementation of adequate vitamin A during immunization, certain pathogen infection or coccidiosis, has a good effect on enhancing the disease resistance, recovery after disease and antibody production.

　　3.维生素D维生素D为无色晶体，不易氧化，但与碳酸钙混合极易受破坏。维生素D的主要功能是促进小肠对钙、磷的吸收，预防佝偻病与软骨症。

　　3. vitamin D vitamin D is colorless crystal, it is not easy to oxidize, but it is easily damaged with calcium carbonate. The main function of vitamin D is to promote the absorption of calcium and phosphorus in the small intestine and prevent rickets and cartilaginous disease.

　　由于长毛兔多以舍饲笼养为主，照射阳光机会不多，不可能通过紫外线的照射而合成维生素D，极易引起缺乏症，特别是高产、生长旺期的兔子。缺乏时常会导致骨骼中钙、磷沉积能力下降。

　　Due to multiple feeding in Angora rabbit, the sun not many opportunities, not through the ultraviolet irradiation and the synthesis of vitamin D, can easily cause deficiency, especially high yield, the growth stage of the rabbit. Lack of calcium and phosphorus deposition in bone is often reduced.
