How To Transition Your Horses Feed

Changes in season can result in both change in routine, and what feed we feel is best for our horses. It is always recommended to introduce all changes to our horses diets gradually, but what exactly do we mean by that?

Gradual Transition -

A typical transition period for changing our horses feed is 7-10 days, though it can be extended for more sensitive horses or if you're making a significant change in the type of feed (e.g., from a high fiber feed to a predominantly cereal based feed). The key is to make changes slowly, allowing the horse's digestive system to adjust. Consistency is key for example feeding your horse at the same time every day, to help the horse’s digestive system function optimally and reduces stress. Even if your horse seems to be tolerating the new feed well, it's still best to not rush and continue introducing the feed slowly. Consider your horse’s age, activity level, and any specific health issues when changing their diet. For example, older horses or horses with metabolic disorders may require a more tailored, slower transition.

Start by mixing a small amount of the new feed with the current feed. Gradually increase the proportion of the new feed while decreasing the amount of the old feed. An example method of how to do this gradually could be as below;

• • Day 1-3: 25% new feed / 75% old feed.
  • Day 4-6: 50% new feed / 50% old feed.
  • Day 7-10: 75% new feed / 25% old feed.
  • Day 10+: 100% new feed

Provide Plenty of Water -

Make sure your horse has constant access to clean, fresh water. Changes in diet, particularly increases in fiber, can cause the horse to drink an increased quantity of water, which can also affect stool consistency and gut health.

What to look out for when changing feeds -

When going through the process of changing your horses feeds it is important to watch for any changes in behavior, droppings, appetite, or signs of colic (e.g., rolling, kicking at the belly, or restlessness). Loose stools, gas, or bloating may indicate that the horse is having trouble adjusting to this change of diet, or that it is happening too quickly. It is also important ensure the horse is maintaining a healthy weight and body condition throughout the transition. If you are ever unsure on any signs your horse may be showing, it is always best to consult your vet.

Assessing feed portions -

If possible, splitting the horse's feed into smaller, more frequent meals rather than one or two large meals mimics the horse’s natural grazing behavior and can be easier on the digestive system. It is recommended horses do not exceed a meal size of 500g per 100kg of bodyweight, so a 500kg horse should not be exceeding individual meal sizes of 2.5kg. It is important to consider this when planning your feeding routines as if meals are too large, the stomach cannot “hold” the meal, leading to ingesta passing through the stomach without being appropriately prepared for later digestion and fermentation in the small and large intestine leading to the horses missing out on essential nutrients. Overly large meals also reduce gut mobility, and increase the risk of impaction colic. There is also the risk of overfeeding the recommended quantity of starch per meal (1g/kg BW) if meals exceed this recommended size, this can increase the risk of ulcers and hindgut acidosis.

Keep track of how much your horse is eating. If your horse is not eating as much as usual, it might be an indication that the change is too fast or that the new feed is not agreeing with them.
