Abstract
The beef cattle population in Kenya is currently ~estimated at 9.09 million heads of which 55% are reared in arid and semi-and areas or rangelands with an animal offtake of about 14 (Animal Production Division, 1987). This level E>f productivity is typical of most East African rangelands but is, nonetheless, considered very low. A major factor that contributes to Low Productivity is low fertility of beef herds (Christie, 1962 and Topps, 1977). However, consideration of fertility -10 the overall Strategy to improve beef productivity is often accorded little attention. Not only does low fertility reduce productivity but it also limits genetic improvement and often leads to an increase in the number of unproductive cows with consequent overstocking and environmental degradation.
