Resumo
O conhecimento do perfil metabólico sanguíneo nos animais permitiu aos criadores e técnicos ferramentas importantes para a otimização da produção, permitindo a eles avaliar condições fisiológicas das vacas e sua adaptação as condições nutricionais e ambientais, porém há de se ressaltar a difícil interpretação de resultados, uma vez que, por ser avaliados no sangue, são rapidamente utilizados para a manutenção de um bom funcionamento corporal e equilíbrio dinâmico, dificultando a elaboração de um tratamento eficiente a médio/longo prazo.
A intensidade da mobilização tecidual pode ser avaliada por exames sanguíneos, denominado de perfil metabólico, que permite quantificar a concentração de vários parâmetros provenientes da mobilização e realizar o monitoramento da adequação das vacas às exigências crescentes de energia, proteína e minerais. Além disso, o perfil metabólico permite o diagnóstico de transtornos metabólicos, de deficiências nutricionais como preventivo de enfermidades subclínicas, além da pesquisa de problemas de saúde e do desempenho produtivo de um rebanho.
The knowledge of the metabolic blood profile in animals has provided breeders and technicians important tools for the optimization of production, allowing them to evaluate the physiological conditions of the cows and their adaptation to nutritional and environmental conditions. However, it is important to highlight the difficult interpretation of results, since, since they are evaluated in the blood, they are quickly used for the maintenance of a good body functioning and dynamic balance, making it difficult to elaborate an efficient treatment in the medium/long term. The intensity of tissue mobilization can be assessed by blood tests, called a metabolic profile, which allows quantifying the concentration of various parameters from mobilization and monitoring the suitability of cows to the growing demands for energy, protein and minerals. In addition, the metabolic profile allows the diagnosis of metabolic disorders, nutritional deficiencies as a preventive of subclinical diseases, in addition to researching health problems and the productive performance of a herd.
