Extract

1. The vitamin A content of the colostrum of one hundred cows, kept under the same conditions of dietary and management, was found to range from 1181 to 35 I.U. per 100 ml.

2. It has been established that this wide range was not due to any differences in dietary, breed or date of calving in animals kept under the same conditions of management.

3. It is suggested that the vitamin A content of the colostrum may be materially affected by the length of the non-lactating period between successive calvings.
