Mineral content of grazing cattle is affected by soil pH and forage species within and between breeds. A three-year study was conducted at six major grazing areas located in Uasin Gishu County, Kenya for cattle grazing on Rhodes and Kikuyu pastures. Frieisian and Ayshire cattle breeds were assigned randomly to two different forage species treatments, Rhodes (Chioris gayana) and Kikuyu (Pennisetum Clandestinum). Kikuyu forage species recorded the highest mineral concentrations (P<0.05). Both Rhodes and Kikuyu forages had generally higher (P<0.05) mineral concentration. Acidity did not appear to be a problem in soil mineral availability since mean pH was 5.6 and higher. Consequently grazing cattle at these locations can be recommended for kikuyu grass as it has average mineral requirements to support optimum animal productivity.
