Validação de modelos matemáticos para predição de consumo voluntário e ganho em peso de bovinos

Abstract: RESUMOAvaliou-se a utilização das equações do Cornell Net Carbohydrate and Protein System (CNCPS) e Nacional Research Council (NRC) nível 1 para predição de consumo de matéria seca e ganho em peso médio diário em condições tropicais de confinamento. Utilizou-se 23 bovinos mestiços Holandês/Zebu confinados em baias individuais com idade média de 20 meses e 260 kg de peso vivo no início do experimento. As dietas experimentais eram isonitrogenadas compostas por dois níveis de ingestão de energia com 50 ou 80% de … Show more

“…Mathematical models are used as tools to estimate the requirements of the animals and the nutritional value of foods in each scenario of agricultural production and therefore has an important role in providing information that can be used in the decision making process in a property (Rezende et al 2011). These sets of information can improve the technical and economic efficiency of animal feed system through computer programs easy access for producers of frogs.…”
