Winter feeding. Great advice!
Winter is a normal time for horses to drop a bit of weight. To a degree, that can be healthy. Theyâre not really meant to stay fat all year, and for easy keepers, ponies and metabolic types, coming out of winter a little lighter can be a good thing.
But some do need extra help.
Horses that have:
dental issues
trouble holding weight
higher energy needs
age-related changes
a heavy workload
recent illness or recovery
poor access to suitable feed
cold, wet living conditions
can struggle once the weather sets in.
Before changing everything, it helps to have a rough idea of how much theyâre actually eating.
A common starting point for total intake is around 1.5â2% of body weight per day, but thatâs only a guide.
For a 500 kg horse, thatâs roughly:
1.5% = 7.5 kg per day
2% = 10 kg per day
For a 100 kg miniature pony, thatâs roughly:
1.5% = 1.5 kg per day
2% = 2 kg per day
That number is total intake, not just hard feed. It includes grass, hay, hard feed and anything else theyâre eating.
Some easy keepers may be closer to the lower end. Many horses are closer to 2%. Horses needing weight gain may need more, often closer to 2â2.5%, depending on the individual, the weather, their teeth, workload, forage quality and how well they digest what theyâre eating.
For a 500 kg horse, that could be around:
2% = 10 kg per day
2.5% = 12.5 kg per day
For a 100 kg miniature pony, that could be around:
2% = 2 kg per day
2.5% = 2.5 kg per day
For weight loss, itâs important not to just stop feeding and hope for the best. For overweight horses use 1.5% of current body weight or 2% of ideal body weight, whichever is larger, as a safe starting point, then adjust from there. The numbers are useful, but theyâre not a fixed rule. Use them as a starting point.
For winter weight gain, the first thing I usually want to add is fibre.
Horses are hindgut fermenters. Theyâre designed to process fibre, and fermenting fibre helps produce heat. Thatâs why more hay is often the best for the horse.
Good options can include:
grass or pasture hay, ideally tested if possible
Rhodes hay
teff hay
beet pulp
soybean hulls
lupin hulls
low sugar hay-based pellets
With hay, you need to know what youâre actually buying.
âPasture hayâ can mean very different things. Sometimes rye and clover hay gets sold as pasture hay, and that can be far too high in sugar for laminitic, metabolic or very good-doing horses.
Rhodes hay can be a useful lower sugar option. Some batches can be quite stalky, so thatâs just something to take note of depending on the horse.
Teff hay can also be useful. Some horses donât do as well on it if the batch is higher in protein or sugar than expected, so again, itâs just something to take note of.
That doesnât mean those hays are bad. It just means hay isnât automatically suitable because of the name. Testing is ideal when you can do it, and if you canât, it helps to at least ask whatâs actually in it.
Winter grass can also be tricky. We can get cold weather, damp ground, sunny days and little bursts of growth. That grass can be high in sugar and protein, and some horses will scour on it, especially if their gut is already unsettled or the grass changes quickly.
For horses needing more condition, Iâm looking at fibre first before even thinking about feeds that are high in sugar, starch, oil or very rich ingredients.
That doesnât mean fat or protein are bad. It means theyâre not where Iâd usually start if the fibre intake, forage quality, salt, minerals and basic diet havenât been sorted yet.
Fibre is the base.
If I do want to add healthy fats for more condition, my first choice is an omega-3 source. Omega-3 is the fat Iâd add because it has an anti-inflammatory role, rather than just being extra calories.
The cheapest option is usually fresh ground linseed/flaxseed. A lot of people get put off because cold-pressed flax oil can be expensive, but whole linseed is usually much cheaper. Ideally, grind it fresh, or grind a small amount and keep it sealed in the fridge for up to a couple of weeks. Freezing is better if you want to store it longer.
Then we have the other basics that are easy to forget.
Salt is important in winter. Theyâre often eating more dry feed, like hay, and may not drink as much in cold weather. Salt helps encourage drinking and reduces the risk of dehydration and impaction colic.
Minerals are important, especially if the diet is mostly hay or untested pasture.
Vitamin E is worth thinking about when theyâre not getting much fresh green grass.
To summarise. Know roughly how much your horse is eating.
Start with forage.
Add suitable fibre before getting complicated.
Be careful with high sugar hay and grass.
Donât trust the front of the feed bag more than the ingredients and analysis.
Add salt, minerals, vitamin E and omega-3s where needed.
Winter feeding doesnât have to be fancy, but it does need to make sense.
