不同品种马属动物的免疫效果分析

Immune Effects in Different Varieties of Horses

目的分析不同品种马属动物的免疫效果。方法对不同地区、不同品种的马属动物进行分群,采用相同的破伤风类毒素及免疫方法免疫,分析不同群之间的抗毒素效价、免疫成功率、形成免疫耐受的程次、马匹淘汰率的差异及平均免疫寿命。结果不同群之间免疫效果存在差异,身体素质和健康状况不同的马匹,免疫效果不同。结论要生产高效价的免疫血清,应选择高质量的马匹,可采用育种方法培育出适合免疫血清生产用的优良马匹。

Objective To analyze the immune effects in different varieties of horses.Methods Horses were grouped according to the species and the regions from which they were purchased,and immunized with the same tetanus toxoid by the same route,and the antitoxin titers,immunization success rates,the numbers of courses when immune tolerance appeared,discard rates and mean life span for immunization of various groups were compared.Results Immune effect showed significant difference in various groups and in the horses with different physical qualities and health statuses.Conclusion The production of high titer immune serum needs the high-quality horses which may be obtained by breeding.
