Grazers vs browsers

Two feeding types. Two natural diets.

Grazers feed primarily on grasses, while browsers select leaves, shoots and other woody vegetation. Understanding these differences is an important part of providing appropriate nutrition for the animals in your care.

The table below outlines the general differences between grazing and browsing behaviour. These are broad feeding categories, and individual species may differ in how they digest and process their food.

How Acacia fits into the BOSKOS range

The BOSKOS range is built around a functional fibre called PREBICEL™, which is made from the whole acacia plant, including leaves, fine branches and woody stems. With formulations developed for different feeding needs, BOSKOS offers options for grazing and browsing herbivores. BOSKOS Mulch provides an additional complementary feeding option.

Choosing the appropriate product and feeding amount depends on the species, its nutritional requirements and the rest of its diet.
