Japanese black cattle with ateliosis showed lower insulin responses during glucose tolerance test.
In order to determine insulin secretability and glucose utilization, a glucose tolerance test was performed in ateliotic cattle of 2 paternal strains; MHO and HSK cattle. MHO and HSK cattle showed different endocrine patterns in our previous study. Area under the insulin concentration curves (insulin-AUC) in the ateliotic cattle were significantly lower (122.3 +/- 59.4 ng.min/ml and 99.2 +/- 24.8 ng.min/ml for MHO and HSK cattle, respectively) than the control cattle (420.2 +/- 175.2 ng.min/ml). These low insulin responses to GTT may have an influence on growth retardation in MHO and HSK cattle.
