Abstract
AbstractGrass silage constitutes a major proportion of the food offered to high producing dairy cows in the western regions of the European Union. In order to achieve optimal milk yield and quality from high genetic merit dairy cows, it is common practice to offer concentrates in addition to grass silage at feeding. The aim of the current study was to combine two existing empirical models in order to allow prediction of the response in milk production to offering varying ratios of grass silage and concentrates to high genetic merit dairy cows, allowing for the fact that grass silage quality can vary. Results have demonstrated that it is possible to predict, with reasonable precision, the milk production response to various combinations of grass silage and concentrates in the diet. This will facilitate investigation of production and economic responses of offering increased levels of concentrates in the diet on milk yield, milk quality and milk value.
