Feeding - Forage

Forage should form the basis of any horse’s diet as they have evolved to chew for up to 18 hours a day. It is really important to provide enough forage to help satisfy their behavioural needs, especially during winter when grass may not be readily available, or turnout time may be restricted. Forage also helps to keep the horse warm acting as an in-built heating system by creating heat as it breaks down the fibre in the digestive system.

Plenty of forage is also vital for a healthy digestive system which will help reduce the risk of colic and stomach (gastric) ulcers. It is ideal to provide your horse with unlimited forage at ground level, but this system may not be appropriate for all horses if they need their intake restricted, for example if they need to lose weight. In this case, you could split the daily forage ration up into several small holed haynets (if your horse doesn’t have back and neck problems) and hang them up throughout the day to extend feeding time.

Current recommendations are to feed around 2-2.5% of the horse’s current bodyweight in forage per day (24 hours). It is never advised to provide below 1.5% of the horse’s current bodyweight in forage per day without seeking vet advice. If weight loss is required, you may consider feeding a lower calorie forage. Research has shown that feeding your horse 50% hay and 50% barley straw will contribute to weight loss1. However, always make these changes gradually and ensure your horse’s teeth are in good shape before introducing straw as it does take more chewing - this will also reduce the risk of colic.

It can be difficult to notice small changes in your horse’s weight when you see them every day. By monitoring your horse’s weight fortnightly through fat scoring and weighing (either on the weighbridge or using a weight tape) you can react to weight fluctuations quickly by adjusting your management accordingly. Get hands on and learn how to fat score your horse.

Feeding in the Field

You may need to feed additional forage for horses living out, depending on how much grass is available. When putting extra forage in the field, make sure there are more piles of hay than there are horses to help avoid conflict.

Feeding – does your horse need more than forage alone?

Many leisure horses do perfectly well on forage alone, but it is difficult to know exactly what amount of vitamins, minerals and proteins they’re receiving to ensure a balanced diet. It is recommended to feed a low-calorie balancer or vitamin and mineral supplement daily to horses that are fed a forage only diet to ensure they’re getting exactly what they need.

There are times when additional bucket feeds would be beneficial, for example elderly horses who struggle to chew forage or those who tend to drop weight during winter. Discuss whether your horse would benefit from additional bucket feeds with a nutritionist to help avoid overfeeding and save money by not buying unnecessary feed!

If concentrate feeds are really needed, feed them little and often to help reduce the risk of colic as horses have a relatively small stomach. Small concentrate feeds will start to be broken down effectively by the stomach. If fed in large amounts, concentrate food will pass unprocessed through to the large intestine which could lead to digestive problems.


Keeping Hydrated

The importance of ensuring your horse has a plentiful supply of fresh, clean drinking water shouldn’t be underestimated during the winter! Adult horses can drink between 24-36 litres (approximately 3-4 buckets) of water per day and this can increase to 40-45 litres (approximately 5-6 buckets) per day, with an increase in forage.

Keeping Hydrated

Water plays an important role in hydration and digestion. If your horse doesn’t have access to enough water, is unable to drink as the supply has frozen, or doesn’t consume enough water, it can affect how food passes along the gut, increasing the risk of impaction colic. This occurs when a firm ball of feed material blocks the intestine.

It’s important to check your water troughs twice a day and to break and remove any ice. You could also fill containers with water, so you have an emergency supply if the taps freeze. If your horse is stabled, adding some warm water into their buckets can prevent the water from freezing overnight, and may encourage a horse to drink if they don’t like the colder water!

Winter Ailments

Winter can increase the risk of your horse developing certain conditions, especially due to wet and muddy conditions. The most common winter ailments include mud fever and rain scald.

Change to Routine

Turning horses out all summer and then stabling them during the winter is common practice at many yards. This adjustment in routine represents a significant change in the horse’s diet and management, so must be completed gradually over 10-14 days to help reduce the risk of colic. You can start by bringing your horse in for a few hours a day with hay and then slowly increasing the amount of time to help avoid a sudden change from being out 24/7 to being stabled for a large part of the day.

With less daylight hours and poor weather to contend with, it can often be a challenge to maintain your horse’s fitness and some owners decide to give their horses a rest period during this time or ride significantly less. In these circumstances, it is vital that care is taken during the ‘roughing off process’.

Feed Management: It will be important to reduce the amount of concentrate feed where necessary, especially if your horse’s workload is going to be significantly decreased. Remember, make changes to feed management gradually to reduce the risk of colic. It may be beneficial for the horse to be gradually changed on to a balancer feed; speak to your vet or a qualified nutritionist for advice specific to your horse’s individual needs.

Monitoring Weight: As exercise is reduced, regularly monitor your horse’s weight and react to any changes by adjusting their management gradually. If your horse is fit and well-muscled and you are planning on reducing their exercise, then you will start to see changes to their body shape due to muscle loss.

Removing Shoes:
In consultation with your farrier, arranging for your horse’s shoes to be removed if you are not exercising your horse regularly, or not at all, could be a consideration. Monitor how your horse is coping and if you have any concerns contact your farrier.

Remember, when bringing your horse back into work following the winter break, preparation is key. Ensuring you are prepared allows for the safest transition back into work for both you and your horse to prevent any injuries, which could set you back months.

Pasture Management

The management of your grassland will vary throughout the seasons and having specific steps in place to prepare your pasture for winter can be really beneficial!
Wet weather brings a risk of fields becoming poached and muddy but there are steps you can take to help manage the mud. The amount of turnout time may need to be restricted to prevent excessive poaching and reduce the risk of winter ailments developing. However, time out of the stable and daily exercise is important for the horse’s mental and physical health.

All horses when out at grass will need access to shelter, either natural such as thick hedges or tree lines, or a man-made field shelter. Even if you think your horse doesn’t use it, on a cold, windy day they are likely to seek a wind-break. If natural shelter is accessible in your pasture it is important to ensure this is not poisonous to your horse and consideration given for any trees that lose their leaves during winter, making them inadequate for shelter. For more information see our advice on appropriate horse shelter.
