Colostrum stored in a frozen condition for periods up to more than a yr. proved satisfactory for feeding calves. Calves receiving colostrum for a longer period than normal made greater gains than similar calves receiving colostrum only during the time it was produced by their dams. Calves fed colostrum for nearly 9 weeks required an avg. of 2 lbs. less milk per lb. of gain than the normal-fed lot. No serious difficulty with scours or other digestive disturbances was encountered in any of the lots. Results of the study indicate that little loss of vitamin A and carotene in colostrum milk occurs during 6 months' storage at -5 F. Abnormally high levels of vitamin A and carotene in the blood of calves at birth may be the result of abnormal conditions in the calf at that time.
