Abstract

High-quality colostrum is important for successful rearing of calves. Parity and length of dry period have been discussed as factors influencing the quality of colostrum.  However, the role of the nutritional plane of the cow during the dry period and its effect on the colostral immunoglobulin G (IgG) concentration remains unclear. Results from studies carried out in sheep suggest that colostrum volume as well as composition can be affected by different energy levels prepartum. Furthermore, recent publications in the field of human medicine have found lower concentrations of IgG in colostrum from women suffering from an altered insulin response. Because dry cows on a high-energy diet are at increased risk to develop insulin resistance, and their colostrum volume and IgG concentration might be affected in a similar manner as that in other species, the objective of this study was to evaluate the effect of different nutritional planes during the dry period on colostrum composition.
