| 摘 要： | 本文对影响饲料采食量的因素、采食量的调控机理及家畜在不同采食水平下的生产效应等有关资料进行了概述,提出,为了提高家畜的生产效率,实现采食量的调控,应保持相互关联的三个平衡关系。在决定饲料采食量的各因素中,营养物质平衡最为重要。在最佳饲料和最适环境条件下,饲料采食量取决于家畜利用能量的遗传潜力。动物生产率是被吸收的养分用于生产的效率,是可消化饲料采食量的函数,能量亏损和胃肠道负载在饲料采食量的控制中发挥重要作用。影响饲料采食量的因素之间以及饲料采食量与其它因素之间存在许多互作关系。虽然通过控制饲料采食量而达到动物生产的最优化目前尚未完全实现,但将来一定能够实现。因此,我们必须对饲料采食量与动物产品等因素之间相互关系的内在规律进行深人的研究。

| Abstract: | A broad outline is given of data relating to the factors involved in feed intake control, to the principles of this process and to the production sesponses of domestic animals to different feed intake levels.IT is suggested that to increase the efficiency of animal production feed intake control should remain three interelating balances. Of the facters determining feed intake process the nutrient balance is the most important.Under optimal conditions of the diet and environment, it should be determined by the animals genetic potential to use energy. Animal production role is a efficiency of absorbed nutrient used for production and is a function of digestible feed intake. The energy deficit and gastrointestinal tract load may play key roles in the feed intake control. Interplay between factors affacting feed comsumption or between feed intake and other factors occurs. Although the optimization of animal production through feed intake control have not realized entiely at present, it was become reality in the future. So we must make deep researchs on inner laws of relationship between feed intake and product etc.from now on. |
