[Amino acid composition and peptide maps of udder and serum albumins in lactating and nonlactating cows].
Amino acids and peptides of albumin hydrolyzates from the mammary gland and blood serum were studied for lactating and nonlactating (dry, pregnant 1-4.5 and 4.5-9 months) black-and-white cows. Most pronounced difference between the content of certain amino acids of the mammary gland and blood serum albumins are established for lactating cows and least pronounced for nonlactating dry cows. Dactylography detected 55-57 fragments of products resulted from trypsin hydrolysis of the mammary gland and blood serum albumins of the animals under study. Differences are found in the content and mobility of certain peptides.
