    Changes in amino acids composition of cows colostrum (during first 72 hours after parturition)

  • Original language description

    Changes in amino acid spectrum of colostrum within the period of 2 to 72 hours post partum were studied in dairy cows of the Czech Red Pied cattle with a genetic admixture of Black Pied Lowland breed (n = 10). Five of them were on the 1st lactation and 5on the 2nd and/or higher lactations. Within the study period, the contents of non-essential amino acids (NEAA) and essential amino acids (EAA) decreased by 22.8 - 63.2% and 27.3 - 65.2%, resp., in dairy cows on the 1st lactation while in those on the 2nd and following lactations the corresponding values were 22.0 - 63.7% and 24.9 - 71.7%, respectively. The dependence of the course of changes in the AA spectrum of cow's colostrum on the time interval elapsing after the parturition could be characterisedby a regression equation y = b0 + b1/x + b2/x2.

    Změny aminokyselinového spektra kravského mleziva v průběhu prvních 72 hodin po porodu

  • Czech description

    Změny aminokyseliného spektra mleziva v průběhu 2 až 72 hod. po porodu byly sledovány u krav českého strakatého skotu s genetickým podílem černostrakatého nížinného skotu (n = 10), z nichž bylo 5 krav na 1. laktaci (prvotelky) a 5 krav na 2. a vyšší laktaci. Obsah NEAA u krav na 1. laktaci se během sledovaného období poklesl v rozpětí 22,8 - 63,2 %, u EAK v rozpětí 27,3 - 65,2 % u krav na 2. a vyšší laktaci ve stejném pořadí o 22,0 - 63,7 %, resp. 24,9 - 71,7 %. Průběh změn aminokyselinového složení mleziva krav v závislosti na době od porodu byl vyjádřen lomenou regresní rovnicí y = b0 + b1/x + b2/x2.
