在實際生產中,維生素添加劑的配合形式多采用多維添加劑。因日糧中添加量很少,必須經擴大預配后再行添加,以免混合不勻,造成浪費,達不到添加的目的。
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.維生素E為無色晶體,在光照、空氣中極易氧化破壞。維生素E具有維持正常繁殖機能和維持肌肉及外周血管系統(tǒng)的正常功能,增強免疫反應和與硒有協(xié)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.
長毛兔缺乏時會引起生殖器官萎縮、衰退,機能失調而影響繁殖力。在種兔日糧中添加高水平維生素E,能明顯提高產仔數(shù)和斷奶育成數(shù);當兔群感染肝球蟲病時,添加高水平維生素E,療效顯著。
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.維生素A維生素A為黃色結晶體,在光照、空氣中極易氧化破壞。維生素A具有維持上皮組織和神經組織的正常功能,缺乏時會影響長毛兔的正常生長發(fā)育和繁殖功能,降低抗感染能力,增加眼病和呼吸道疾病的發(fā)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.
在免疫接種、某些病原菌感染或球蟲病期,補充適量維生素A,對增強長毛兔的抗病力和病后恢復及抗體產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.維生素D維生素D為無色晶體,不易氧化,但與碳酸鈣混合極易受破壞。維生素D的主要功能是促進小腸對鈣、磷的吸收,預防佝僂病與軟骨癥。
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.
由于長毛兔多以舍飼籠養(yǎng)為主,照射陽光機會不多,不可能通過紫外線的照射而合成維生素D,極易引起缺乏癥,特別是高產、生長旺期的兔子。缺乏時常會導致骨骼中鈣、磷沉積能力下降。
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.
