...The N content of the urine used in the 15 experiments (Table 4a) were typical for cattle urine (Dijkstra et al., 2013; Selbie et al., 2015; Gardiner et al., 2016), ranging from 6.8 to 11.4 g l−1 (average 9.11 g l−1 ± 0.35)....

...Martin (1966) noted that urine and dermal N losses during measurements of N balance in sheep were positively related to N intake, presumably due to the positive relationship between N intake and urinary excretion of N as urea (Dijkstra et al., 2013)....
[...]
...For instance, Dijkstra et al. (2013) reported that at low N intake, the proportion of urea N in total urine N is much lower compared with higher N intake....

...Forage diets are often high in soluble crude protein (CP) content, which exacerbates the situation by increasing the proportion of N (40% to 75%) excreted in the highly labile form of urine [5]....

...Elevated microbial N capture in the rumen when more energy substrates are available for microbes may reduce net NH3 production and consequently urea excretion, but will increase urine losses of nucleic acid N synthesized as part of microbial biomass production (Tamminga, 1992)....

...Energy supply and urine N excretion Urinary N originates from various sources including rumen losses, incorporation of dietary N into microbial nucleic acid N, animal maintenance requirements and losses related to inefficient conversion of absorbed amino acids (AAs) to milk protein (Tamminga, 1992)....
