Abstract

Like athletes training for the Olympics, dairy cows face the challenge of eating enough to fuel their energy expenditures. Cows devote so much energy to milk production that they can't consume enough feed to meet their other needs. That results in negative energy balance, says animal scientist Diane Spurlock. She is studying how negative energy balance might contribute to fertility problems and affect other "fitness traits" that influence cows' well-being.
