摘要
目的在Passive test(PT)行为测试中,评价导盲犬的心率变化特征,以期为导盲犬的前期筛选提供科学参考信息。方法选取中国导盲犬大连培训基地的66只犬在培训前进行PT测试,测试过程通过摄像头进行记录,其中37只犬在训练结束后被基地认定为不适合成为导盲犬,即淘汰犬。心率信息采用RS800CX心率表进行记录。结果 PT测试可以考察犬的活跃程度,测试中平均得分在导盲犬(2.0±0.11)和淘汰犬(3.1±0.22)之间具有显著性差异(P<0.05),导盲犬相对活跃度低于淘汰犬。在整个测试中,心率变化的平均值在导盲犬组(19.5±8.45)与淘汰犬组(19.6±11.35)之间没有显著性差异;在活跃程度较低的犬中(PT测试中得分在3分以下),导盲犬的静息心率值显著大于淘汰犬。结论本研究显示在PT测试中,具有成为导盲犬潜力的犬,其活跃度相对较低,静息心率相对较高,PT测试结合心率的分析可以为导盲犬的前期筛选工作提供指导信息。
Objective The aim of this study was to identify the law about heart rate changes of guide dogs in Passive test（ PT）,to provide scientific information for early identify of dogs best suited to guide dog work. Method The subjects were 66 dogs from Chinese guide dog training center of Dalian. The dogs were tested using the PT before training and the behaviors were video-recorded. After training,37 failed guide dogs which were not suitable for guide dogs were determined by China guide dog training center. The heart rate reactions were recorded by RS800 CX Polar-Systems. Result The PT permits us to study active level of dogs. In the PT,the average score of guide dogs（ 2. 0 ± 0. 11） was significantly different from the failed guide dogs（ 3. 1 ± 0. 22）,the guide dogs were less active than the failed guide dogs and there was no significant difference in mean values of heart rate changes between the guide dogs（ 19. 5 ± 8. 45） and the failed guide dogs（ 19. 6 ± 11. 35）. In the dogs with lower active level（ score〈 3）,the rest heart rate in guide dogs was significantly higher than that in failed guide dogs.Conclusion This study indicated that potential guide dogs have lower active level and higher rest heart rate compared to failed guide dogs,Heart rate reactions associated with PT can provide valuable information for early screening of guide dogs.
