摘要

The objective of the study was to determine the chelate effects of organic trace minerals onbioavailability and function of dairy cow.Thirty multiparous Holstein dairy cows were enrolled in this experiment during mid-to late lactation.Beginning 3 weeks prior to the experiment,all cows were fed a basal diet that had been formulated to NRC (2001) inorganic trace mineral requirements.Cows (n=10 per treatment) were assigned to one of the following three dietary treatments and treatments were administered for 4 weeks.Control:Basal diet with inorganic NRC level trace mineral.
