Dry matter intake efficiency considers the efficiency of milk produced relative to intake of feed. It is calculated by taking milk (lbs) or either fat- or energy-corrected milk (lbs) divided by dry matter intake (lbs). Higher efficiencies equate to fewer nutrients excreted to the environment per unit of feed consumed.
Energy-corrected milk formula:
(12.82*fat (lb))+(7.13*protein(lb))+(0.323*milk (lb))
3.5% fat-corrected milk formula:
(0.4255*milk (lb))+[16.425*((fat%/100)*milk(lb))]
