A study of the growth of the alimentary tract of the young cockerel

Abstract
The growth of the alimentary tract of male domestic fowl was described from measurements of dry wt of the whole and component parts of the tract from hatching to 10 wk of age. Quadratic regression equations were derived to express the growth of the birds and the growth of their alimentary tracts. From hatching to 2 wk there were marked alterations in the proportions of the size of the whole tract.
