🐴 It’s easy to get complacent about how much fibre and energy your horse is intaking when they have unlimited access to pasture. If they continually graze, how could they possibly lose weight or be unable to gain and maintain weight?
🌾 There is a considerable variation in the nutritive value of different forages and obviously some options are going to provide more energy and nutrients than others, but for the sake of keeping this article of a healthy length, today we are just going to focus on the quantity of forage a horse should be intaking on a daily basis.
🐎 Let’s start out by looking at how much forage a 500kg horse needs to intake on a daily basis.
• 1.5% (7.5kg) of body weight in dry matter per day would allow some horses to maintain weight, but would see other horses with a quicker metabolism or poorer digestive/immune health lose weight.
• 2% (10kg) of body weight in dry matter per day should allow most horses to maintain condition unless their health is challenged due to illness, disease, age etc.
• 2.5-3% (12.5-15kg) of body weight in dry matter per day may result in some horses becoming overweight, but may be adequate for other horses who are harder keepers due to any number of reasons.
💧 It’s important to remember that these percentages are based on dry weight values, which essentially means the weight of the forage once the moisture content has been removed. 1kg of pasture with a moisture content of 20% is only going to provide 800g of dry matter.
⚖️ Now I want you to imagine yourself in a paddock of grass that is overgrazed or less than 10cm in height. Grab a pair of scissors and walk around this paddock until you have collected yourself 12.5kg of grass (12.5kg - 20% moisture content = 10kg dry matter).
⏰ You only have 16 hours in a 24 hour period to achieve this because you need the other 5 hours in your day for other essentials such as drinking, sleeping, interacting with your friends, and digesting your food.
🌿 Is it going to be possible for you to achieve this task? Possibly. But it’s going to take you a lot of time and energy moving around to make sure you can collect enough grass in your allocated time slot. Wouldn’t it be easier and less energy-consuming if someone gave you 5kg of hay (moisture content already taken care of) to fulfill 50% of your requirement?
🌱 Overgrazed or short pasture can make it rather difficult for some horses to fullfill their forage requirements if they are challenged with a fast metabolism, digestive upset or immune issues that reduce their ability to digest and utilise dietary nutrients, age, dental health, and so on.
💠 Horses are a large animal and they need a lot of roughage to sustain themselves and maintain a healthy gastrointestinal tract - they don’t have a giant fermentation vat inside them for no reason!
