Effect of feeding time on urinary and faecal nitrogen excretion patterns in sheep

Nitrogen Balance of Dairy Cows Divergent for Milk Urea Nitrogen Breeding Values Consuming Either Plantain or Perennial Ryegrass

“…Dietary and management strategies focusing on diverse swards and grazing management have been extensively explored as ways to reduce N losses [ 4 , 16 , 17 , 18 , 19 ], with the use of narrow-leaf plantain ( Plantago lanceolata L. (PL)) showing promising results for reducing total N excretions and UN concentrations in dairy cows [ 20 , 21 ]. PL is known to contain secondary bioactive compounds, such as acubin, catalpol, and acteoside [ 22 , 23 ], that have been reported to have antimicrobial and diuretic effects [ 22 , 24 ], which may influence the N partitioning of the animals.…”

Land use and water quality

“…Papers within the second category examine new actions to mitigate the loss of N from sheep and dairy farm systems by manipulating the timing of feeding sheep, thereby reducing urinary N (Thomson et al 2021) and adding a flocculating agent to farm dairy effluent to reduce contaminant loads in effluent irrigation (Chisholm et al 2021). The agent causes nutrients, sediment and E. coli to settle to the bottom of the pond.…”
