Innovating feeding strategies in dairy sheep farming can reduce environmental impact of ewe milk

Dairy sheep systems are relevant for the economy of many rural areas of the Mediterranean Basin and the optimisation of their productive factors is necessary to improve their competitiveness and to reduce their environmental impact. The objective of this study was to assess, through a farm-scale lif...
