The Pre-Natal Development of Skin and hair in Cattle (Bos Taurus L.)

Abstract

A histological study has been made of the development of the skin and hair follicles in 33 foetuses, ranging in age from 68 to 274 days, and seven new-born specimens, of various breeds of Bos taurus L. Skin samples were taken from the mid-lateral region of the trunk, and both serial sections and whole mount preparations have been examined. Extensive use has been made of' counts of the follicle and hair population as well as skin and hair follicle measurements which hitherto have apparently received little attention in studies of this type.
