Effect of energy and nitrogen supply at pasture on milk production and urea content in the humid Spain



Effect of energy and nitrogen supply at pasture on milk production and urea content in the humid Spain



Multi function grasslands: quality forages, animal products and landscapes Proceedings of the 19th General Meeting of the European Grassland Federation, La Rochelle, France, 27-30 May 2002: 566-567



A study was performed to determine whether milk urea content could be used to balance the diet in systems based on grazed grass-clover swards with strategic use of concentrates. Three groups of 20 dairy cows were monitored during lactation in a humid area of Northwest Spain.
