1中兽医药在现代养殖业中应用的现状现代畜禽养殖业,追求最佳生产状态(人工饲养、无公害养殖)。健康状态(阴平阳秘),以畜为本,在最佳心理、生理状态下高效优质生产畜禽产品的最佳模式。而亚健康状态(应激状态)、亚临床状态(隐性失衡)、临床状态(显性失衡)的存在,必然导致畜禽抗应激能力与搞病能力下降,生产性能降低,产品不安全。1.1现代化畜禽养殖业面临的问题畜禽适应能力和抗病能力下降,应激因素和 1 veterinary medicine in the modern breeding industry in the status quo Modern livestock and poultry breeding, the pursuit of the best production status (artificial feeding, pollution-free breeding). Health (yin and yang Yang Mi), livestock-oriented, in the best psychological, physiological state of efficient and high quality production of livestock and poultry products the best model. However, the existence of sub-health state (stress state), subclinical state (recessive imbalance) and clinical state (dominant imbalance) will inevitably lead to the decrease of stress resistance ability and disease-causing ability of livestock and poultry, the decrease of production performance and the unsafe product . 1.1 Problems Faced by Modernized Livestock and Poultry Breeding The problems of adaptive capacity and disease resistance of livestock and poultry, stress factors and
