Age-correlation of blood values in the rock pigeon (Columba livia).
Hematological adaptations to age (1-17 years) and about variability per se for free-living rock pigeons Columba livia are presented. Increasing age is correlated with decreasing values of hematocrit and hemoglobin. A marked reduction of lactate dehydrogenase (EC 1.1.1.27) activity in the first 2-3 years may be caused by a training-based increase of the relative portion of the aerobically working red breast muscles (responsible for endurance) at the expense of the proportion of anaerobically working white breast muscles. The age-correlated increase in glucose could indicate a decreasing tolerance for carbohydrates. Optimal flight performance is achieved by the doves at an age of about 2-3 years; the high performance is retained until an age range of 7-9 years.
