An investigation wasconducted to evaluate the nutrient level of grazing livestock as influenced bythe sampling periods in Punjab state districtSargodha,Pakistan.Twenty composite soil and pasture and twenty five blood samples were collectedat two different sampling periods dur ing December 2010 to March, 2011,respectively. Higher soil content of all elements except iron was observedduring December than those found in Mach at the 2nd harvest duringthis pe riod but all mean values were above the critical levels investigatedfor soil for the requirements of forage crops. Forage, potassium, magnesium andcopper levels did not differ between samplings. Calcium, sodium, zinc,manganese, cobalt and selenium were higher during December, while reverse wastrue for forage iron reflecting the soil iron contents. The sodium, manganese,iron and selenium in forage were found to be deficient than the requirements oflivestock during both sampling times in this investigation. From the fourminerals assessed in the serum calcium, magnesium and zinc levels were highafter the December in March. The macro mineral which were found to be moderatelydeficient at this animal farm are sodium and magnesium. Micro elements mostlikely to limit livestock production efficiency are copper, zinc, manganese andcobalt. Specific mineral supplementation should be supplied containing copperand zinc, as both pasture and blood plasma samples exhibited their deficiency.The present investigation suggests the requirement and provision of anappropriate specificity tailored mineral mixture to ruminants in this specificstudied area. The objective of this study was to determine deficiency or excessof various minerals to have the knowledge of the status of different minerlelements for supplementation if necessary.
