家畜抗病机理和抗病育种

Advances in Disease Resistance and Breeding of Domestic Animals

疾病的发生给畜牧业造成了巨大的经济损失。疾病抗性通常由非特异性免疫和特异性免疫控制。除免疫基因外的非免疫基因对疾病的抗性也起很大作用。家畜疾病抗性是一种普遍现象 ,这种现象的本质 ,也就是疾病抗性是由基因控制的。这表明 ,对疾病抗性的选择有一个坚实基础。抗病育种是控制疾病的有效方法之一。

The spread of diseases among domestic animals can cause enormous economic losses in animal husbandry. Disease resistance is usually mediated by innate and acquired immunity. Non-immune genes can also be involved in disease resistance. There are many documented examples of genetic differences between animals in resistance to specific diseases or tolerance of infection. This indicates that there is an excellent foundation upon which to base selection for disease resistance,although selection is but one of several ways in which genetics can be used to help control disease problems. Selection for disease resistance will help enable the specific traits. Genetic management is the most efficient component of disease control strategies.
