How Much is One Scoop of Horse Feed
The Importance of Weighing Feed
How many times have you had to describe your horse's ration and found yourself saying, "He gets a scoop of this and a scoop of that"? Though this is the way diets are described by most horse owners, there are many disadvantages to measuring your horse's feed amounts in "scoops" rather than weight.
Why Weigh?
To determine dietary requirements, horse characteristics are first considered. These include age, breed, workload, metabolism, and weight. For example, for optimum digestive health each horse requires at least 1% of its body weight in forage every day, which would be at least 5 kg (11 lb) for a 500-kg (1,100-lb) horse. If you have a horse that is restricted from pasture or has access to very little pasture and you are looking to substitute hay as a forage source, it is important to know how much hay he is receiving in order to establish if he is receiving adequate forage.
When looking at fortified feeds, experienced nutritionists have formulated these in accordance with characteristics of certain classes of horses, including their weight. Based on the formulations, they then recommend a minimum amount of the feed that each type of horse requires to meet its specific nutrient requirements.
Therefore, by weighing feeds you not only know exactly how much your horse is getting daily, but also if your horse is receiving a balanced diet and meeting requirements for forage and the nutrients that are important for achieving optimum health, development, and performance.
Weighing feed leads to peace of mind that your horse is meeting its nutrient requirements, and often feed costs can be cut through determining how much of each feed is required. The need for expensive vitamin and mineral supplements is decreased when a fortified feed is fed at the correct amount daily.
Weight vs. Volume
In any given feed room, you are likely to come across a wide variety of measuring utensils. Open scoops, dippers, ice cream containers, tins, jars, and bowls are commonly used to convey feed to the trough, and each may hold a different volume of feed.
Equine nutrition consultants often hear from horse owners that they use a 1-kg (2.2-lb) scoop. Due to different feeds having different densities, this is hardly accurate. Although a scoop of chaff has the same volume as the same scoop of pellets or muesli (textured feed), the varying densities of these feeds means that they weigh very different amounts. A 2-litre (1/2-gallon) scoop of a pelleted feed may weigh up to 1.5 kg (3 lb), whereas that same 2-litre scoop of lucerne (alfalfa) chaff will weigh much less.
Method of Weighing
Feeds may be weighed accurately and conveniently using common types of scales. A hook scale, like those used for weighing fish or luggage, is easily used to weigh hay or haylage by hanging the haynet or hay bag off the scale. If you're not using a net or bag, then a bundle of hay may be tied up with twine then hung from the scale. Feeds may be weighed in a similar manner using an empty pail or bag as a receptacle to hang from the scale. Simply fill your scoop with feed or grain and then empty it into the bag before hanging the bag on the scale. In this manner, you can determine the weight of all feedstuffs in each of the scoops you normally use. Be sure to take into account the weight of the bag or net by weighing that first and subtracting this amount from the final reading or using the tare function, if available, with electronic scales.
If a flat platform scale is your available weighing device, then weighing feeds and cereals may be accomplished by using the scoop or a pail as a receptacle. First, weigh your scoop or pail and note the weight of the container or press "tare" on the scales if they are electronic. Then, fill the scoop with feed and weigh again or empty into the pail already on the scale to weigh the contents. For electronic scales with a tare function, the weight displayed should be the weight of only the feed contained within the scoop or pail. For other scales, you may have to manually subtract the weight of the container from the total amount of feed and container combined. In order to weigh hay on a platform scale, you may need a larger platform. A piece of rigid cardboard or wood may work well for this. Be sure to zero the scale or note the weight of the platform before placing the hay atop it. Then, simply balance the portion of hay or haylage you wish to measure on the platform and note the weight displayed. Again, depending on whether or not the scale is electronic, the amount displayed will be the weight of the forage or the forage and platform combined.
Hay and feed shouldn't require weighing each time you feed your horse. You can simply estimate how many sections of hay your horse requires daily by determining the average weight of a section of each batch of hay you get. Feed amounts can be determined by knowing approximately how much a scoop of each foodstuff in your horse's diet weighs.
