• cows
  • Colostrum Ig concentrations of 227 cows from 13 herds were quantified with a quantitative ELISA for IgG, IgG1, IgG2, IgA and IgM. (uu.nl)
  • Colostrum samples of continuous milked (CM) cows (n = 38) were compared with colostrum samples of cows (n = 189) after a traditional dry period (DP) of at least 42 days. (uu.nl)
  • Results indicated that colostrum Ig concentration was significantly lower in continuous milking systems where IgG, IgG1, IgG2, IgA and IgM concentrations were reduced by half compared with cows that had a planned dry period. (uu.nl)
  • immune
  • Right after puberty and in cases of illness these immune factors decline and only colostrum has been shown to work on replacing the supply. (naturalhealth365.com)
  • When relating the results from this study to recommendations for colostrum management it can be concluded that although colostrum Ig concentrations are significantly lower in a continuous milking management system an adequate passive immune transfer can still be achieved based on colostrum quality provided colostrum feeding management is optimal.
