The Nutritive Value of Colostrum for the Calf

Abstract

the factor most essential for the survival of the newborn calf is contained in the non-fatty fraction of colostrum, of which a very small quantity is sufticient to protect the calf against fatal scours. T o define this factor more closely, the protective values of small quantities of colostral whey, dialysed whey and the 'immune lactoglobulins' (as defined by Smith, 1946) were compared with that of the separated colostrum from which these fractions were derived. c. 148.
