	abstract = {Milk production and urinary nitrogen (N) concentration were measured in late lactation dairy cows grazing a perennial ryegrass-
white clover pasture, pure plantain and an area that is comprised of 50\% perennial ryegrass-white clover and 50\% pure
plantain by ground area (50-50 pasture-plantain), (n=12). Milksolids production was greater (P=0.01) for cows grazing plantain
(1.67 kg MS/cow/d) than those grazing pasture (1.50 kg MS/cow/d), with cows grazing 50-50 pasture-plantain intermediate (1.60
kg MS/cow/d). Urine-N concentration was 56\% lower (P<0.001) for plantain (2.4 g N/L) and 33\% lower for 50-50 pasture-plantain
(3.6 g N/L) than pasture (5.4 g N/L). Plantain may offer environmental benefits to dairy systems by reducing the urinary N
concentration deposited on the soil from grazing cows in late lactation.},
