Changes in the elimination rate of I131-labelled heterologous albumin from the blood of chickens during their postnatal development
The rate of elimination of heterologous albumin from the blood of chickens was found to vary considerably during the first week of age. The half-life obtained for 2-day-old chicks was 1.4 days while that found in birds between 1 and 6 weeks of age ranged from 0.8 to 1.1 days. The results are in agreement with previous observations that the onset of immunological activity of chickens occurs during the first week of age and that their full immunological competence inachieved between the 3rd and 4th weeks of age.
