Abstract: Objective To analyze the dynamic change of basic physiological indexes between SPF and conventional beagle dogs at different growth time. Method The blood samples of 2-month-old, 6-month-old and 9-month-old were collected between SPF and conventional beagle dogs. Result The MCH and WBC of 6-month-old SPF beagle dogs were different significantly compared with those in conventional beagle dogs. The MCV, MCH and MPV of 9-month-old SPF beagle dogs were significantly lower than those in conventional beagle dogs. With the increase of months, the basic physiological indexes between SPF and conventional beagle dogs began to stabilize. Conclusion Basic physiological indexes of beagle dogs are affected by their different backgrounds.

摘要： 目的 研究不同月龄不同级别比格犬血常规指标的动态变化。 方法 采集 2 月龄、6 月龄和 9 月龄普通级和SPF 级比格犬的血液样本,分析测定各组样本的血液生理指标数据。 结果 6 月龄 SPF 级比格犬的平均红细胞血红蛋白量和白细胞计数低于普通级,差异有统计学意义(P<0. 05) ;9 月龄 SPF 级比格犬的平均红细胞体积、平均红细胞血红蛋白量以及平均血小板体积低于普通级,差异有统计学意义( P< 0. 05) 。 随着月龄的增加,同级别比格犬的血常规指标趋于稳定。 结论 不同等级环境对比格犬的血液指标具有一定的影响。
