Project No: PS8.1

Title: Stocking rate determination in the Karoo
Project Leader: Y Ntlakaza & Dr PCV du Toit Starting date: 1989
Partners: Closing date: 2010
 
Objectives: to determine the optimum stocking rate under grazing for the karoo by using merino sheep, dorper sheep and angora goats, the period of occupation per paddock is four months, i.e. the recommended two-camp rotational system, however, the stocking rate at the recommended norm is duplicated and this particular paddock is subdivided into four paddocks, where the animals rotate every 14 days
Location: Grootfintein, Afrikaner/Hereford paddocks
