Feeding an additional 3 Mcal of NE daily should increase body condition from 4 to 5 in 75 days. 226 Mcal required/3 Mcal fed daily = 75 days meet energy requirements Current BCS = 5 Cows are shorted 3 Mcal of NEm/day In this declining BCS situation, one Mcal of tissue NE mobilized replaces 0.80 Mcal of feed NEm-Thus, when cows are shorted 3 Mcal of feed NEm daily, they drop from a BCS 6 to 4 in 60 days. (226 Mcal mobilized x .8)/e Mcal feed NEm shorted daily = 60 days. These scenarios demonstrate the importance of having cows in good body condition (BCS 6, plus or minus) when winter begins so body energy reserves are available in times of critical need without resulting in BCS dropping below 5. d Feeding 1 lb.
