Packed cell volumes (PCVs) from 3-, 7-, 14-, 21-, 28-, and 35-day-old clinically healthy chicken anemia agent (CAA)-free and specific-pathogen-free (SPF) leghorn chicks were compared with PCVs from age-matched clinically healthy CAA-free broiler chicks. The PCVs of the SPF chicks regressed significantly (F = 20.6, df = 2/3, P < 0.025) on age in a linear fashion. The PCVs of the broiler chicks regressed significantly (F = 9.56, df = 2/3, P < 0.05) on age in a cubic parabola. The mean PCVs of the broiler chicks were significantly (P < 0.05) higher than PCVs of SPF chicks at every tested time interval. Results indicate that PCV values are higher in broiler chicks than in SPF leghorn chicks, and that PCVs increase as chicks age. Clinicians, diagnosticians, and investigators who intend to work with chicken blood must be aware of these differences.
将3日龄、7日龄、14日龄、21日龄、28日龄和35日龄临床上健康的无鸡贫血因子（CAA）且无特定病原体（SPF）的来航鸡雏鸡的红细胞压积（PCV）与年龄匹配的临床上健康的无CAA肉仔鸡雏鸡的PCV进行比较。SPF雏鸡的PCV随年龄呈线性显著下降（F = 20.6，自由度= 2/3，P < 0.025）。肉仔鸡雏鸡的PCV随年龄呈三次抛物线显著下降（F = 9.56，自由度= 2/3，P < 0.05）。在每个测试时间间隔，肉仔鸡雏鸡的平均PCV均显著高于（P < 0.05）SPF雏鸡的PCV。结果表明，肉仔鸡雏鸡的PCV值高于SPF来航鸡雏鸡，且PCV随雏鸡年龄增长而增加。打算处理鸡血的临床医生、诊断医生和研究人员必须了解这些差异。
