Molecular factors influencing maintenance energy requirements in mature beef cows



Feed costs represent a significant input cost in the cow-calf sector. The majority of the feed energy needed by the cow is used to meet the animal’s ‘maintenance requirements’. During pregnancy, cows may be able to reprioritize their energy use, which allows the cow to use less energy to maintain herself, and divert more towards the growing calf.

Better understanding maintenance requirements and energy metabolism in the mature cow may lead to the development of management and nutritional approaches that improve feed efficiency of cows.
