The small organic population, and the fact that G×E was only found for one of the longevity traits, does not justify development of either separate breeding values or separate breeding programs for Swedish Red cows in organic production today. Thus, overall breeding values for longevity estimated for bulls in conventional production can be used in organic production. These results support the results of an earlier study (Sundberg et al., 2010) in which genetic correlations for production, fertility, and SCC were estimated between organic and conventional production. However, the organic standards and the conditions for conventional production vary to some extent between countries.
