| Different traits have been defined to describe the performance of dairy animals during their lifetime: productive lifetime, lifetime production, life efficiency and contribution trouble-free cows that reach the performance optimum of lactations. This continuous performance should be on basis of good roughage feed efficiency. Within the present total merit indices it is not possible to determine which cow fulfils these demands on longevity, health, performance and cost reduction. Further research is necessary to investigate the suitability of this trait for breeding value estimation or if the calculation of an index may be more useful. |
