With the new breeding values in August 2019, NAV (Nordic Cattle Genetic Evaluation) releases the first part of the Saved Feed index. The Saved Feed index will in the future include two separate breeding values for maintenance efficiency and metabolic efficiency. Many countries and cattle breeding companies have already developed breeding values for feed efficiency, but many of them are struggling with low reliability due to lack of sufficient data.
The Saved feed index will consist of two breeding values; maintenance efficiency, which captures the energy requirement for maintenance, and metabolic efficiency, which reflects how well the eaten feed is utilized. The breeding value for metabolic efficiency is expected to be launched later.
