Start from one rule and never leave it: the forage does not move with the workload; the bucket does. A working horse whose owner feeds by the calendar, or by habit, or by what the horse in the next stable gets, will drift fat in quiet weeks and thin in busy ones. A horse fed by workload stays level through both.
Forage Stays the Constant Base
Hay, haylage and grazing are not the part you adjust first, or much at all. Forage is the foundation the horse's digestion is built around, it occupies the long hours between feeds, and it should stay generous and steady as work rises and falls around it. When owners talk about changing feed with workload, the change belongs almost entirely in the bucket, not in the forage net.
Keep forage quality consistent as well. A sudden swap to much richer hay at the same moment work increases muddies the picture: you will not know whether a change in condition or energy came from the bucket, the hay or the work itself.
Raising Hard Feed Gradually as Work Builds
When work builds, over a new fitness program, a competition season or a heavier schedule of lessons or driving, raise the hard feed gradually to meet it. Stepped over days rather than switched overnight is the rule: add a little, hold it for several days while the digestion adjusts and you watch the horse work, then add a little more if the work and the horse's condition still call for it.
Sudden large increases risk digestive upset and the kind of fizzing, unsettled behavior owners often blame on temperament when it is really a ration that outran the work. Match the increase to work actually done, not work planned; a week of rain-canceled sessions is a week when the increase waits, however good the program looked on paper.
Cutting Promptly When Work Drops
The downward direction is where owners often fail, because it feels unkind. When work drops, including on rest days, through injury, a holiday or a lost shoe that takes days to replace, cut the hard feed promptly. A resting horse still eating a full working ration stores the surplus as fat and can turn fresh, reactive and hard to handle, quite apart from the strain extra weight puts on legs and digestion.
Promptly does not mean starving the bucket to nothing overnight in a panic. It means the reduction starts with the first missed work, in step with the drop, while forage stays generous so the horse still has plenty to eat and chew.
Reading Condition by Hand
Your check that the balance is right is your hand, not the feed scoop. Run your palm over the ribs regularly: you want to feel them with light pressure under a smooth covering, not hunt for them under fat or count them at a glance.
Weigh tape readings and photographs help, but hands catch change first.
Behavior is the second check. Excess hard feed on too little work often shows first as excitability, spookiness or stable restlessness rather than visible fat.
Putting the Changes on a Shared Schedule
Stepped changes only work if every feeder serves the current step, and yards rarely have one feeder. The feed duties sit in the Care Teams plan on KinsLe: Rosa makes up the morning feed on weekdays, Callum covers the evening feed, and Rosa and Callum alternate weekends, with the current ration for each meal written against the duty and changed in the plan the day a step up or a cut begins. The person holding the scoop sees the ration as it stands now, not as it stood last week.
That record also shows the pattern over a season: when the increases happened, when the cuts landed, and how condition responded, which makes next year's program easier to plan honestly. The Care Teams record on KinsLe turns a principle everyone agrees with into a ration every feeder actually serves.
