    Assessment of mineral deficiencies among grazing areas in Uasin Gishu County, Kenya.
    (International Journal of Nutrition and Food Sciences., 2014) Shisia, Silvanus K.; Ngure, Veronica; Nyambaka Hudson; Jumba Isaac; Oduor Fredrick
    A study conducted in the major grazing areas of Uasin Gishu involved twenty-eight (28) soils, twenty-eight (28) forage and forty-two (42) serum samples collected in six divisions at different sites. The purpose of the study was to determine the macro-and trace elements in soils, forages and animal serum, and compare to the recommended standards so as to identify those that could be presenting deficiencies in the area. Soils were extracted for available macro-minerals; Sodium (Na), Potassium (K), Calcium (Ca) magnesium (Mg) and trace elements; Iron (Fe), Manganese (Mn), Copper (Cu) and Zinc (Zn; the forage samples were assayed for the same elements plus phosphorus as total concentration on dry matter (DM) basis while blood serum was analyzed for the same forage elements plus molybdenum (Mo). Atomic absorption spectrophotometer (AAS) and UV/visible spectrophotometer were used to analyze the metal elements and molybdenum respectively. Soil and Forage analysis of samples from southern region including Kesses and Ainabkoi revealed lower levels in both macro and trace elements analyzed. Serum samples from grazing areas situated in southern region revealed similar deficiencies in most minerals. The factors responsible for the variations as soil pH, forage species and cattle breed were investigated using correlation analysis.
