Assessment of the productivity of livestock in and outside the Wase grazing reserve
The performance or livestock in Wase was assessed using flocks and herds in and outside the Wase Grazing Reserve. Age at first calving of cattle in and outside the grazing reserve was 5 years. The corresponding calving interval was 2 years. The calving percentage or 92 ror cattle in the grazing reserve was higher (P < 0.05) than that of 54 for cattle outside the grazing reserve. Ages at first lambing of sheep in and outside were 12.5 and 13 months respectively. Lambing interval however, was 8.6 months while corresponding lambing percentages were 75 and 71. Average age at first kidding in goats in the grazing reserve was 12 months while outside was 12.5 month. The kidding interval was 8 months while kidding percentage on the other hand was 56 in the reserve and 46 outside the reserve. The average lactation yield of cows (P > 0.05) in the grazing reserve was 401.5 litres while outside was 486.0 litres. The mean growth rates of calves between 6 and 12 months in and outside the grazing reserve were 9.8 and 5.6 kg/month respectively. The mean growth rates or lambs in and outside the grazing reserve were on the other hand 1.9 and 1.7 kg/month respectively, while the corresponding kids growth rates were 1.6 and 1.3 kg/month. Mortality rates recorded in adult cattle, lamb and kids in the grazing reserve were 4.8%, 7 and 7% while the rates outside the reserve were respectively 2.4, 5 and 18%.
