Abstract:This study aims to estimate and validate the accuracy of estimated Total Digestible Nutrient (TDN) content in forages based on the chemical composition of feed. Data on nutrient composition for estimates were obtained from the BR-CORTE database consisting of 86 types of forages and primary data from observations consisting of 19 types of forages. Analysis data is used Pearson correlation, multiple linear regression, determination coefficient (R2), and root mean square error (RMSE) for estimation models, varian… Show more
