Horses derive about 40% of energy from hindgut fermentation, and sainfoin's profile optimizes this process. Start by feeding 1.5-2% of body weight daily to see sustained benefits in training horses.
Pair with Targeted Add-Ons like EquiShure During Stress Periods For high-stress events like travel or competition, combine sainfoin hay with hindgut buffers such as EquiShure. Monitor effectiveness through manure consistency (firm, segmented balls indicate health) and performance metrics like energy levels. This duo addresses dysbiosis spikes, cutting colic risks that affect 4-10% of horses annually.
Consult Your Vet for Personalized Plans and Regular Check-Ups Work with a veterinarian to tailor protocols, tracking ulcer prevalence (up to 94% in performance horses) and colic history. Schedule bi-annual fecal exams and scopes to quantify risks early.
Invest in Forage Quality to Maximize Hindgut Energy and Cut Supplement Costs High-quality forage like sainfoin leverages the hindgut's 40% energy contribution, minimizing pricey additives. Poor hay forces reliance on supplements, inflating expenses in a $91M market.
Implement Small Changes: Swap Alfalfa for Sainfoin Transition gradually over 7-10 days from alfalfa to sainfoin hay. Expect topline gains and stronger hooves within 4-6 weeks, as tannins curb parasites and support absorption. This simple shift yields measurable improvements without overhauling routines.
