必需微量元素碘对家兔的营养作用

The Nutrition Effects of Essential Trace Elements Iodine on Rabbits

影响家兔生产的因素很多,如品种、饲料营养、饲养管理、疾病防治等,其中饲料营养是影响家兔生产的最重要的物质基础。科学合理地利用饲料,是提高家兔生产效益的根本保证。碘是动物生长发育和生产过程中所必需的微量元素,虽然需要量很小,但对机体的作用是巨大的。其主要功能是参与甲状腺激素的合成,并通过甲状腺激素发挥多方面的生理作用。家兔缺碘时,会导致生长发育受阻,毛皮质量下降,新陈代谢紊乱等症状,从而影响动物生产性能。家兔摄碘过多会发生中毒症,影响生长发育。为了更好地在家兔生产上发挥碘对动物的营养作用,笔者就微量元素碘对家兔的营养作用进行了综述。

There are so many factors that can effect the production of rabbit, such as breeds, feed nutrition, feeding management, the prevention and treatment of disease et. al.. The feed nutrition is the most important material base. How to use the feed scientifically and reasonably is the fundamental guarantee for improving rabbit production. Iodien（I） is one of the necessary trace elements in the growth and production of animals, although its requirement is very small, but it has a huge effect of the body. The main function of I is participating in the synthesis of thyroid hormone, and throid hormone is the mediator of the I functions. If the rabbit is I deficiency, it will lead to growth and development retardation, fur quality reduction, metabolic disorder, et. al.. Thus it will affect animal productivity. But too much absorb of I will result in toxieosis and have influence on the growthing development. This paper briefly reviewed the nutrition effects of essential trace elements l on rabbits.
