The Role of Adrenocortical and Medullary Hormones on the Bursectomised Chicken through the Glycemic Response

Abstract

The effects of bursectomy on blood glucose, adrenocortical and adrenomedullary activities were tested in White Leghorn chicken. It has been shown that bursectomised chicken exhibited consistent hyperglycemia on the 10th day, 17th day, and the 24th day after the bursectomy. On these days, total catecholamine in bursectomied chicken increased. Bursectomy may have caused a higher corticosterone synthesis and storage in the bursectomised chicken on the 10th day after bursectomy, and corticosterone release on the 17th and the 24th days after bursectomy. From this study, it can be inferred that hyperglycemia in bursectomised chicken on the 17th and the 24th days is due to the relasese of corticosterone. However, hyperglycemia in bursectomised chicken on the 10th day is difficult to explain.
