The project aims to increase the sustainability, competitiveness and profitability of beef production by using by-products throughout the feed-animal-carcass chain. This is achieved by using by-products from the energy and food industry as feed for the final rearing of cows from milk production and by increasing the utilization of the slaughtered animal carcass "from nose to tail". Using larger parts of the animal reduces the climate impact per kilo of food produced and ensures a sustainable domestic food supply. During final fattening, different feeding strategies are compared with regard to feed consumption, growth, carcass and meat quality. The profitability of the different alternatives is evaluated. The project involves researchers, advisors, farmers, the food industry and public administration. The profitability calculations will be made by advisors who will disseminate the results via their channels. The project takes place at the initiative of Skövde slaughterhouse.
