Descripción

This study aimed to develop predictive models for nitrogen (N) excretion in dairy cattle using a database of 847 observations from 24 studies conducted in Latin America (Brazil, Chile, Argentina, and Uruguay). The dataset included fecal and urinary N excretion; DMI; NDF intake (NDFI); nitrogen intake (NI); dietary concentrations of CP, ether extract, and NFC; forage proportion (FP); milk yield (MY) and composition; MUN; and body weight
