Dairy Cattle N Excretion Calculator

The Dairy Cattle N Excretion Calculator was developed based on the Cornell Net Carbohydrate and Protein System (Fox et al., 2004). It enables users to quickly characterize rations, individual dairy cattle, and groups of dairy cattle to predict the N partitioned to growth, milk production, pregnancy, urine, and feces. From there, N use efficiency and N volatilization from the barn floor are estimated.
