A study made in Mkhuze Game Reserve and Ndumu Game Reserve in Natal, focused on the dietary habits of the impala and the nyala, showed that the amount of dicotyledons in their diets varied seasonally. In the diet of nyala its content was 83.2% and impala's diet contained a lesser figure of 52% dicotyledons. The diet grew richer in fiber content and dietary proteins were less. The reverse occurred in the rainy season. As the rainy season arrived, both the species took to a diet of mainly monocotyledons, and the impala consumed more of them. The diet contained more proteins than fibers.
