The accumulation of body fat has an influence on metabolism in the period of initiation of lactation, reducing the impacts of diet deficiency. However, animals with a high body condition score tend to suffer more from negative energy balance, resulting in exacerbated catabolic processes, in addition to reproductive dysfunction. The increase in non-esterified fatty acids in the circulation, resulting from lipolysis, leads to an increase in circulating ketone bodies, characterizing a condition of ketosis.Acesso AbertoMedicina VeterináriaBovinosBioquimicaCetoseFisiologiaMetabolismoCNPQ::CIENCIAS AGRARIASArtigo de Evento
