Beef cattle productivity under traditional and improved management in Botswana.

A comparison of productivity over a 4-year period from indigenous type beef cattle under two production systems in Botswana is reported. The two systems are: the traditional system on unenclosed communal grazing (cattle post) and ranching within fenced paddocks. Calving percentages, 7-month old calf weight, calf mortality and post-weaning growth to 18 months of age under cattle post conditions were 46.4 per cent, 122.5 kg, 10.2 percent and 88.5 kg respectively. Corresponding figures for cattle on the fenced ranches were 74.0 per cent, 177.4 kg, 8.5 per cent and 105.8 kg. These results indicate overall productivity estimates of 51 and 120 kg of weaner calf per cow per year and 86 and 188 kg of 18-month old calf per cow per year for the cattle post and fenced ranch respectively.
