Feed Intake Patterns and Immediate Glycaemic and Insulinaemic Responses of Horses Following Ingestion of Different Quantities of Starch From Oat, Barley and Grains

Table 5: Mean ± pooled SD for items of the glycaemic and insulinaemic response following the ingestion of crushed oats and barley and cracked maize, respectively, in quantities equal to 0.8, 1 and 2 g starch/kg of BW and meal (The means represent the individual steps of the main factors, e.g. ‘1 g starch/kg BW and meal’ as average over ‘oats’, ‘barley’ and ‘maize’ or ‘oats’ as average over ‘0.8’, ‘1’ and ‘2 g starch/kg BW and meal’, in each case for 4 horses x 3 measurements).
