The Vitamin A, B(B₁) and G(B₂) Contents of Milk throughout the Year¹

ABSTRACT

The vitamin A, B(B₁) and G(B₂) values of raw milk have been determined at all seasons of the year.

It was found that the vitamin A value of the milk is comparatively constant from season to season and that 0.5 to 0.75 cc. of the milk per day fed six days in the week will give a unit gain in weight (a growth of 3 grams per week throughout the eight weeks' experimental period) at any time in the year. The milk contains, therefore, about 1.3 to 2 units of vitamin A per gram.

When 8 cc. of milk per day were fed 6 days in the week, as the only source of vitamin B(B¹), an average gain in weight of 3 grams a week for the experimental period (unit gain) was secured. The milk contains, therefore, about 0.1 unit of vitamin B(B₁) per gram.
