Amino Acids and other Non-Protein Nitrogen Blood Substances in Relation to Milk Secretion

Abstract

Conclusions

1. The amino-acids absorbed from the blood by the mammary cannot account for more than 35% of the milk proteins. 2. While there is a slight loss of blood uric acid, creatine and creatinine to the lactating mammary gland, it is evident that these substances are not important in the nitrogen metabolism of the lactating gland.
