dc.description.abstractIn this study, by using a FT-NMR spectrometer operating at 60 MHz for proton, the solvent spin-lattice relaxation times (T-1) in colostrum were measured versus the days of lactation, whereas the T-1 values in dehydrated colostrum were determined versus concentration of its hydrating solid. Data show that the spinlattice relaxation rate (1/T-1 or R-1) in colostrum is linearly dependent upon the inverse of time (1/days), and the R-1 in dehydrated colostrum increases linearly with increasing concentration of its hydrating solid content (C). From data, the total paramagnetic contribution of ions in colostrum to the R-1 was found to be negligible. The dehydrated colostrum data indicates that the R-1 in colostrum is linearly dependent upon its hydrating solid content. Therefore, the R-1 changes in colostrum were analyzed in terms of the relaxivities (increase in relaxation rate per unit concentration of solid) and the concentrations of milk constituents. Such an analysis provides a relation similar to that of the R-1 in dehydrated colostrum. The current data imply that the relaxation changes in colostrum by days may be explained through changes in the concentrations of milk constituents. Also, the data suggest that the relaxation mechanism in colostrum can be explained in terms of fast chemical exchange of protons between free water and water bound to milk constituents.en_US
