LAL CHAND DHARMANI AND JIWAN DAS CHOPRA 165
Towards the end of lactation the amount of carotene fed was slightly less, probably on account of the
low content of carotene in the green maize.
The output of vitamin-A (in milligrams) in the milk throughout the lactation is given in Table
IX. Vitamin-A has been calculated according to the formula of Bartlett and co-workers [1938].
Because of the limitations in accuracy of the vitamin-A determinations and the calculations involved,
these figures may be open to criticism, but they are presented because they give the greatest insight
into the quantitative relationship of intake and output at our disposal.
