BACKGROUND: Controlling postprandial hyperinsulinaemia is important in insulin dysregulated (ID) horses to reduce the risk of laminitis. OBJECTIVES: To evaluate postprandial insulin responses of ID vs. non-insulin dysregulated (NID) horses to feedstuffs varying in non-structural carbohydrate (NSC) and crude protein (CP). STUDY DESIGN: Randomised crossover. METHODS: 18 adult mixed-breed horses (13.3 ± 2.2 years; 621 ± 78.8 kg) were individually fed (~1g/kg BW) specific feedstuffs within two crossover studies. 8ID & 8NID were used in Study A and 11ID & 5 NID in Study B. Study A, all horses were randomly fed once: cracked corn (CC: ~74% NSC & ~9% CP), ration balancer with low protein (RB-LP: ~1..View full abstract
