The quality of the mixture determines both its yield potential and the nutritional quality of the forage at the various stages of use.<\/p>\r\n<h2><strong>Respecting sowing dates<\/strong><\/h2>\r\n<p><br \/>Grass-legume mixtures are mainly sown in late August to early September, or in spring under a companion crop. It is advisable to include, within the crop rotation, a crop that is easy to weed (such as cereal crops) in order to control weed pressure.<\/p>\r\n<p>In addition, carrying out a false seedbed (e.g. shallow cultivation) when possible helps to secure establishment and therefore the quality of your grassland.<\/p>\r\n<p>The quality of establishment determines how well the species are synchronised with each other and, consequently, the UFL-PDI concentration of the mixture.<\/p>\r\n<h2><strong>Applying fertilisation adapted to the mixture<\/strong><\/h2>\r\n<p><br \/>A balanced grass-legume mixture should be managed with 0 to 30 nitrogen units per cut, depending on the desired level of intensification.<br \/>Over-fertilisation of grasslands leads to an increase in soluble nitrogen content (rather than true protein) and reduces the development of legumes.<\/p>\r\n<h2><strong>The timing of use is essential to forage quality<\/strong><\/h2>\r\n<p>As the season progresses, forage availability increases, but its nutritional concentration decreases. A balance must therefore be found between the quantity harvested per use (with total annual yield remaining unchanged) and forage concentration.<br \/>To produce 28 litres of milk per cow per day on grass alone, it is preferable to target more frequent utilisation during the season, with smaller individual harvests.<br \/>In a paddock system, if vegetative growth is greater than expected, it is better to mow part of the area rather than graze grass that is too mature.<\/p>\r\n<h2>Final thoughts<strong><br \/><\/strong><\/h2>\r\n<h2><strong>In conclusion, it is entirely possible to produce a rich and balanced ration based solely on grass, provided that several conditions are met:<\/strong><\/h2>\r\n<ul>\r\n<li><strong>the use of a suitable forage mixture,<\/strong><\/li>\r\n<\/ul>\r\n<ul>\r\n<li><strong>high-quality establishment,<\/strong><\/li>\r\n<li><strong>the ability to utilise it consistently at the optimum growth stage.<\/strong><\/li>\r\n<\/ul>\r\n<p>Forage management objectives must be defined according to the farming system, workload and the climatic conditions of the year. On a typical dairy farm, <strong>it is possible to utilise 80% of grass at its optimum stage<\/strong>, which is sufficient to meet the full nutritional requirements of lactating cows.<\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Making smart use of grasslands is a sustainable way to reduce feed costs in dairy farming: Example: \u20ac45\/1,000 L for an all-grazing ration, compared with \u20ac80 to \u20ac120\/1,000 L for a maize-based ration.
