The effect of continuous and rotational grazing of sourveld on the selection of plant fractions by simmentaler heifers

Abstract

In a grazing trial conducted at the Kokstad Agricultural Research Station, the selection of six plant fractions by cattle grazing sourveld was investigated. Relations between the selectivity of the cattle and the dry matter digestibility (DMD) and crude protein (CP) content of these fractions were examined. The effects of continuous and six‐paddock rotational grazing (each at 1,0 and 2,3 animals/ha) on selectivity were examined.
