Critical minerals for ruminants and non –ruminants
“Minerals comprises of the ash obtain after complete

Makes up 3-5% of the body weight of animal
Macro Minerals:” Minerals normally present at greater levels in
animal body or needed in large amounts in the diet (found in
concentrations > 100 ppm)”
Micro (Trace) Minerals: “Minerals normally present at low levels
in animal body (found in concentrations < 100 ppm).”
