Grass for hay and silage: Hay Master

Hay or haylage is an important part of your horse’s rations. At least 60% of its ration must consist of roughage. The rations of horses with low energy needs may even consist entirely of roughage. Hay Master was developed specially for the production of hay and silage. It consists of high-yielding grasses that are suitable for horses. A Hay Masture pasture will yield between 10 and 12 tonnes per hectare. Hay Master is only suitable for hay fields. Hay Masture pastures cannot be used for grazing.

Hay Master

A Hay Master pasture yields hay with an excellent effective fibre content and a good feed value. The grasses contained in Hay Master were specifically selected for use by horses. Horses must chew their roughage well to ensure optimum performance of their stomach and intestines. That’s why Hay Master consists of grass species with a high effective fibre content, such as cocksfoot and tall fescue. The grass species timothy contained in the seed mixture makes the grass extra palatable. Hay Master yields the healthiest, most palatable roughage for horses.

Low fructan content

Fructan is a sugar (a carbohydrate) that is produced by grass plants under the influence of sunlight. Especially in the case of cold nights and intense sunlight grass plants produce a lot of fructan. That’s because it works as antifreeze for the grass. Fructan is one of the main causes of laminitis. It is only partly digested in the small intestine, resulting in high sugar levels in the hind gut that disturb the bacterial balance in the intestines. This leads to the formation of toxic substances that may cause laminitis.


Barenbrug has done a lot of research into the fructan (sugar) contents of different grasses. Some grass species are known for their low fructan contents, but even within a species, some varieties contain more fructan than others. The Hay Master varieties of course all have a very low fructan content.

Deep rooting

The roots of the varieties contained in Hay Master can reach depths of up to 90 cm. In this respect they differ substantially from cow grass varieties, whose roots reach depths of up to 25 cm. A great advantage of deep rooting is that minerals and moisture can be taken up from deep down in the ground. Even in dry periods, a Hay Masture pasture will produce large amounts of grass - up to 30 percent more than cow grass. Another advantage of the grasses in Hay Master is that they dry quickly after mowing, preventing the risk of mould and decay and ensuring fresh, healthy roughage.

Energy content

Horses obtain energy from roughage. Horses with an intensive training programme need more energy than horses with a lighter training programme or retired horses. With Hay Master you can determine the energy content of your horse’s roughage yourself. If you mow your grass before it flowers, you will obtain roughage with a 20% higher energy content. Horses that are fed high-energy roughage need less concentrated feed. If you mow your grass after it has flowered, you will obtain low-calorie roughage with a maximum bite, preventing boredom and overweight in your horse. A hay analysis will give you a proper understanding of the feed value of your hay. That’s ideal in composing your horse’s total ration. Do bear in mind that hay of spring cuts has a different feed value than hay of autumn cuts.
