Forage - either hay or pasture - is the most natural and preferred feed for horses providing the foundation for all equine diets. Although forage should make up the main part of the diet, and can meet your horse's energy requirements, forage alone will not meet all of their nutritional needs. Different types of forage provide different levels of protein, vitamins, and minerals that may not support your specific horse's needs.

Using the Gro 'n Win range of products, it is easy to tailor your horse's feeding program to meet the unique nutritional requirements for work and life stages. Ration balancers such as Gro 'n Win are designed to provide all of the vitamins and minerals your hay is lacking without providing nutrients your horse doesn't need. The amino and fatty acids in Gro 'n Win are scientifically proven to benefit your horse's overall health by providing essential building blocks for muscle development and aiding in immune response.

By utilizing a diet with low starch and sugar you can help prevent or regulate many nutrition-related disorders such as Laminitis, Insulin Resistance, Typing-Up, Cushing's Disease, EPSM, and HYPP. By decreasing the insulin spike in your horse's diet, you can also lessen hyperactivity creating a smoother, quieter performance in the ring or in the barn.

Helpful Tipz:

Weighing Your Horse without a Scale

Knowing your horse’s weight is important for such tasks as determining feeding rates, deworming, and dosage of other medications. Few people have access to a scale, and the typical heart girth weight tape can easily be off by up to 150 pounds or more. Here is a simple formula involving two measurements on the horse, taken in inches, which can be used to generate a very accurate weight predication.
(Heart girth x heart girth x body length) / 330 = Weight
The number 330 is a constant value that is used for mature horses. Should you be measuring a yearling, use the number 301 in place of the 330, and if you are measuring a weanling, use 280 as your constant value.

Body length will take two people to measure, and it is important to consider the disposition of the horse you are trying to measure so no one gets hurt. This measurement is taken from the point of the shoulder (run your hand down the angle of the shoulder and feel for the end of the scapula bone), straight along the horse’s side, and to the point of the buttock. The horse must be standing squarely for this measurement to be accurate.

Heart girth is taken in the same manner as the traditional weight tape, using the highest part of the withers and keeping the tape as close behind the elbow as possible. Measurements to compare an individual horse’s weight should be taken at the same time of the day, preferably prior to morning feeding and watering for the most accurate readings.
