Assessment Of Pasture And Plasma Minerals Of Cows A Case

Vincenzo Tufarelli

Lactating cows resulted in higher plasma Fe concentration compared to dry cows (3.8 versus 2.6 mg/L; p<0.01). Conclusions. From our findings, it can be concluded that the observed minerals level meets the needs of ruminants and the plasma level of different minerals is affected by the physiological stages of cows.

 · Pasture herbage contains up to 20 elements, but not all are indispensable. The minerals required for good plant growth were found at adequate concentrations in the majority of pastures . The exception was P; only 74% of pastures contained the 3.5 mg P/kg DM that is considered optimal for plant production (McNaught, 1970).

Meeting Mineral Requirements at Pasture

The best way to assess minerals needs is to compare pasture analysis to requirements. A farm should build an inventory of forage tests over time to account for seasonal and weather variations on mineral uptake by the pasture. If, over time, the forage test is above the levels in Table 1, then no further action is needed on that nutrient.
