Change of amino acid profile in Charolais cows´colostrum and transient milk during the first week post partum

A herd of 37 Charolais cows was used to evaluate the changes in amino acids in colostrum and transient milk during the first week after parturition. Colostrum and milk samples were taken by hand milking immediately after delivery and at 24, 48, 72, and 168 hours post-partum. Concentrations of differ...

Description
Summary:	A herd of 37 Charolais cows was used to evaluate the changes in amino acids in colostrum and transient milk during the first week after parturition. Colostrum and milk samples were taken by hand milking immediately after delivery and at 24, 48, 72, and 168 hours post-partum. Concentrations of different amino acids were measured using an automatic amino acid analyser. The post-partum period was characterised by significant increases in the concentrations of methionine, isoleucine, lysine, phenylalanine, glutamic acid, and proline. Simultaneously, the concentrations of valine, cysteine, aspartic acid, serine, glycine, and arginine decreased. Inconsistent figures were determined for histidine, leucine, tyrosine, and alanine concentrations between the two consecutive years.
