a comparison of oxygen affinity of haemoglobin in calves aged 6 days , which was composed of about 80 % of fetal haemoglobin and about 20 % of adult haemoglobin , and in adult cows , which contained exclusively adult haemoglobin , showed that the oxygen-binding capacity of haemoglobin was lower in calves .
