The following is written by Kate Hore RNutr(Animal) R.Anim.Technol (Cert). Head Nutritionist at NAFDark days, cold weather and winter is upon us. Inevitably this means changes for our horses, both in terms of diet and often routine too. As any change can disrupt the balance of the digestive tract microbiome, it is worth being aware and ensuring we take the right steps to keep our horses gut happy.Forage Changes Know What Youre FeedingThroughout the year, forage as long fibres should be the basis of the diet. For any horse, general advice is to not drop below 1% of bodyweight (BW) as forage, as a minimum for gut health. Remember that guide is for dry matter (DM) forage, so it is important to weigh your forage and take into account its moisture content.For example, a 500kg horse should have a minimum of 5kg DM forage, but that might mean up to 10kg of haylage in the net for a relatively wet haylage (50% moisture). Increasingly, we see much drier haylages produced, so check with your supplier and make sure you know what you are feeding. If feeding hay, around 90% DM is typical, so that 5kg DM relates to 5.5kg as fed.What winter forage lacks, whether stabled at night or wintering out, is much input from the grass. Grass growth stops when the soil temperature drops below 5oC, so very little nutrition is coming from their grazing, this results in a greater reliance on preserved forages. Grazing conditions may influence gut health through winter too. In very wet conditions, we find the intake of wet grass can disrupt gut balance, which may be seen as a change in the consistency or number of your horses droppings, or water passed alongside normal faeces.Winter StablingFor many, winter means longer time spent in the stable for our horses. Stabling can be an essential and practical part of winter management for some, but it does bring its own digestive challenges. The horses gut evolved to work most efficiently when grazing for around 16-18 hours per day eating, walking, eating, walking repeat. Therefore, even for horses on ad lib forage the stable still challenges gut health by hugely reducing step count. We need to encourage horses to continue to move in the box. Think about splitting forage, positioning feeders or nets across the box from each other, with water and salt lick in the other corners to encourage natural movement. Try to maintain turnout as much as possible where fields are in good condition, or if access to a turnout paddock is possible.GastriAid for Gut MaintenanceWinter sees increasing challenges for the gut. Therefore, whether tucked up in a stable or wintering out, feeding NAF Five Star GastriAid daily is advised to help maintain a healthy digestive tract in all horses and ponies. NAF Five Star GastriAid combines herbs for mucosal health and natural rate of passage, with digestive mopper-uppers like bentonite clay, and NAF BioG our unique combination of prebiotics, probiotic yeast and new postbiotics, working in synergy for total tract health.NAF GastriAid for Total Gut HealthSaliva supportMaintain a healthy pH balanceMuscoal integrityPromote nutrient uptakeDigestive binderRemember, digestion is a continual process in horses and their gut is always designed to be working actively. Particularly true during the day, as they and their gut do rest more at night. Therefore, it is recommended to split NAF Five Star GastriAid into multiple feeds through the day, as practical.Explore NAFs complete range of supplements and grooming products on our website, in our app, and at our Totnes Store.
