ABSTRACT
Meat productivity and quality of beef are determined by a number of factors, including pedigree traits of animals. Meat productivity is closely related to the biological patterns of their growth and development. Considering the patterns that affect meat productivity enables effective growing and fattening of livestock and obtaining commercially viable beef. To predict economically useful traits in beef cattle breeding, interior indicators can be used, as they reflect the metabolic picture of the animal's body. The research studies in physiology and biochemistry of livestock aimed at revealing the persistent mechanisms of a growing animal organism make them relevant. The article identifies a correlation between the interior indicators and the fattening indicators of three experimental groups of steers. The main forecasting factors of meat productivity indicators have been substantiated. Regression coefficients have been found and show how much the live weight varies depending on the determining factors. Meat productivity predicting procedures have been modeled with respect to the protein content in blood serum.(AU)
RESUMO
A produtividade e a qualidade da carne bovina são determinadas por diversos fatores, incluindo características de pedigree dos animais. A produtividade da carne tem relação íntima com os padrões biológicos de seu crescimento e desenvolvimento. A consideração dos padrões que afetam a produtividade da carne possibilita o crescimento e engorda eficazes dos rebanhos e a obtenção de carne bovina comercialmente viável. Para prever características economicamente úteis na criação de gado de corte, indicadores de interior podem ser usados, visto que refletem a imagem metabólica do corpo do animal. Tornam-se relevantes os estudos de pesquisa em fisiologia e bioquímica da pecuária com o objetivo de revelar os mecanismos persistentes de um organismo animal em crescimento. O artigo identifica uma correlação entre os indicadores internos e os indicadores de engorda de três grupos experimentais de novilhos. Os principais fatores de previsão dos indicadores de produtividade de carnes já foram comprovados. Coeficientes de regressão foram encontrados e mostram o quanto o peso vivo varia em função dos fatores determinantes. Os procedimentos de predição da produtividade da carne foram modelados em relação ao conteúdo de proteína no soro sanguíneo.(AU)
