Plasma glucose, insulin and NEFA response to i.v. glucose tolerance test (IVGTT, 0.3 g of glucose i.v. /kg of BW) of Finnhorse mares before and after the grazing season.

aBasal, average concentration at 10 and 5 min before IVGTT; CR180, clearance rate during first 180 min of IVGTT; AUC180, area under the curve during the first 180 min of IVGTT; NEFA, non-esterified fatty acids.bNG, semi-natural grassland group; CG, cultivated high-yielding pasture group.cCovariate (May) was removed from the model, if the effect was not statistically significant (P > 0.10).Plasma glucose, insulin and NEFA response to i.v. glucose tolerance test (IVGTT, 0.3 g of glucose i.v. /kg of BW) of Finnhorse mares before and after the grazing season.
