SPF大白猪和长白猪群体生理生化特性分析

摘要

Objective To determine the reproductive physiology and blood physiological and biochemical characteristics of SPF Yorkshire and Landrace swine.Methods Ten reproductive physiology parameters,19 blood physiological parameters and 18 blood biochemical parameters in SPF Yorkshire and Landrace swine were measured using conventional methods and the differences between population,between age groups and between both sexes were analyzed.Results There were no significant differences(P>0.05) in reproductive physiology parameters and most blood physiological and biochemical parameters of the SPF Yorkshire and Landrace swine.A few of parameters,such as blood physiological indices GRAN,HGB,RDW,PLT,PCT,and blood biochemical indices ALKP,CHOL,TBIL,BUN,showed significant difference(P<0.05) between populations,between age groups and between both sexes,however,the values of difference were rather small,deviated from the normal range.Conclusion The physiological and biochemical characteristics of SPF Yorkshire and Landrace swine are basically stable and there is no significant difference compared with other laboratory miniature pigs.This study will provide valuable basic data for raising velvet yield,establishment of animal models and evaluating the genetic quality of closed colony.%目的 研究分析SPF大白猪、长白猪生殖生理和血液生理生化特性.方法 常规方法测定SPF大白猪、长白猪群体10项生殖生理指标、19项血液生理和18项血液生化指标,统计分析各指标在不同群体、不同年龄、不同性别间的差异.结果 SPF大白猪、长白猪生殖生理指标和血液大部分生理生化指标差异不显著(P>0.05),个别指标如血液生理指标GRAN、HGB、RDW、PLT、PCT,血液生化指标ALKP、CHOL、TBIL、BUN在品种间、不同年龄以及不同性别之间差异显著(P<0.05),但其偏离正常值范围较小.结论 SPF大白猪、长白猪在生殖生理和血液生理生化等方面基本稳定,与其他实验用小型猪相比差异不大,本研究为其标准化饲养、动物模型的构建以及封闭群猪群遗传质量的评价提供了重要的基础数据.
