A stratified sampling method was used to select 156 dairying households from representative Divisions in Nyandarua County. The stratification was based on cattle grazing systems (CGS) and agro-ecological zones (AEZs) across the Divisions. The objectives of the study were to assess status of smallholder dairy cattle production in relationship to CGS and AEZ, major challenges facing smallholder dairy production, and the opportunities for improvement. Data collected included the characteristics of the farm, family, farmer, feeds and feeding, dairy cattle and their performance, milk uses and markets, and the dairy production services. The information on the challenges facing dairy production and the opportunities for improvement was obtained from discussions with livestock extension workers, dairy co-operatives, milk processors, and from secondary sources. The present results indicated that the average farm size was 3.5 Ha and 41, 38, and 44% of the households fed dairy stock with improved fodders, grass hay, and concentrate supplements, respectively. Among the households, about 44, 38 and 32% had access to artificial insemination (AI), extension, and all weather roads services, respectively. Households keeping crosses of the dairy breeds were 59% while the average herd size was 5.3 heads consisting of 40% cows in milk. The average calf live-weight gain was 322g/ day and milk yield per cow was 8.4kg/day. About 65% of the milk was marketed at an average price of 15.00 KES/kg, equivalent to 0.205 US$/kg. As the levels of dairy intensification increased, there were significant increase in milk production per hectare and decrease in calf live-weight gains (P<0.05). On the other hand, as the level of agricultural potential increased, there were significant decreases in milk production and marketed milk per farm (P<0.05). It was concluded that smallholder dairy cattle production was below the potential for Nyandarua County and was influenced by the CGS and AEZs. The major challenges in smallholder dairy production included poor road network and milk marketing, high costs and inaccessibility of dairy production inputs and support services, inappropriate dairy production technologies, and limited value addition of milk.

The levels of important macro and trace minerals were assessed in the plasma of lactating camels kept by pastoralists in Kenya. The average plasma Ca and Na concentrations were below while mean concentration for K, P, Fe, Zn and Co were within the reported range. Mg concentration was above the reported range. Plasma concentration of Ca, K, Na and Zn decreased from dry to wet season, and of Mg, P and Co increased. Plasma Fe and Co were same in both seasons. Other factors that may affect the plasma concentration of these minerals were also assessed.

A model for the establishment of a four-dimensional regional geodetic reference datum is presented. Starting from the three-dimensional integrated geodetic network model, formulations for the establishment of a four-dimensional regional datum are developed. Astronomic latitudes, astronomic longitudes, gravity values, gravity potential differences, gravity differences, and GPS-vectors are considered as observables. The estimated parameters defining the datura are point coordinates, deflections of the vertical and geoidai undulations, and velocities and accelerations on the positional coordinates. The network datum is considered observed over several epochs with parameters estimated from previous epochs being introduced into later epochs as stochastic prior information parameters.
