BALANÇO ENERGÉTICO NEGATIVO EM FÊMEAS BOVINAS LEITEIRAS - UMA REVISÃO

Abstract

Negative Energy Balance (NEB) is a common metabolic challenge faced by dairy cows during the postpartum period, resulting from an imbalance between energy demand for milk production and feed intake. Energy supplementation emerges as a crucial tool in the management of BEN, providing an additional source of energy to compensate for the energy deficit caused by high milk production. The inclusion of highly digestible energy sources, such as protected fats and fermentable starch, can help balance the energy metabolism of animals and reduce the mobilization of body energy reserves. In addition to energy supplementation, dietary manipulation also plays an important role in mitigating BEN. The formulation of balanced diets, with the appropriate proportion of energy, protein, minerals and vitamins, is essential to meet the nutritional needs of lactating cows and minimize the effects of BEN. Nutritional management practices, such as regular monitoring of cows' body scores, environmental control and management of the transition between phases of the production cycle, are crucial to maximizing the benefits of nutritional strategies and promoting the health and well-being of cows flock.
