“…The estimated EVs for milk production traits in 305 days were higher for LROG and as they were affected by lower feeding costs for low production breeds. Similar results were obtained from Polish Holstein (PH) and Polish Red (PR) cattle [ 21 ]. Calving performance is considered as an important functional trait in dairy cattle [ 33 ].…”

“…Dystocia involves direct expenses, such as veterinary treatment and additional labor force, and also economic impact due to herd information effects. Kosińska–Selbi et al [ 21 ] estimated the EVs of calving traits for Polish dairy cattle breeds using a bio-economic model. The economic value of stillbirth was observed for the Polish Holstein (EUR −1.53) and Polish Red (EUR −1.67) breeds, and that of dystocia for Polish Holstein (EUR −0.94) and Polish Red (EUR −1.26).…”

“…The economic effect involved in the economic value of cow mortality means profit loss as the animals are not sold for slaughter, also heifer replacement and carcass extermination expenses. The analysis of Polish Red cattle breeds indicated that the EV for cow mortality was from EUR 1208 to EUR 1239 [ 21 ].…”

“…The SimHerd model [ 18 ] is widely used in many dairy cattle modeling studies, i.e., for deriving economic values for setting breeding goals [ 13 , 21 ] or for investigating the economic consequences of crossbreeding [ 22 ]. The SimHerd program models milk yield, feed intake, reproduction and diseases.…”

“…Dystocia was corrected using stillbirth and cow mortality. The regression model can be described as follows [ 11 , 13 , 21 ]:

where NetReturn ijk l is the average annual net return, resulting from the i-th simulated replicate (i = 1,…,1000) for the j-th simulated level (j = 1,2) of the trait x ij . ß a denotes the corresponding regression coefficient and, at the same time, represents the estimate of the EV of trait x ij .…”

Assessing the economic importance of traits is crucial for delivering appropriate breeding goals in dairy cattle breeding. The aim of the present study was to calculate economic values (EV) and assign the importance of health traits for three dairy cattle breeds: Lithuanian Black-and-White open population (LBW), Lithuanian Red open population (LR) and Lithuanian Red old genotype (LROG). The EV estimation was carried out using a stochastic bio-economic model SimHerd, which allows the simulation of the expected monetary gain of dairy herds. The simulation model was calibrated for LBW, LR and LROG breeds, taking into account breed-specific phenotypic and economic data. For each trait, two scenarios were simulated with a respective trait at different phenotypic levels. To obtain the EVs, the scenarios were compared with each other in terms of their economic outcomes. In order to avoid the double counting of the effects, the output results were corrected using a multiple regression analysis with mediator variables. The EVs were derived for the traits related to production ECM (energy-corrected milk), fertility, calving traits, calf survival, cow survival and direct health. To demonstrate the importance of health traits in herd management, we provided reliable EVs estimates for functional traits related to herd health. The highest EV for direct health traits, caused by an increase in of 1 percentage point, were those found for mastitis (EUR 1.73 to EUR 1.82 per cow-year) and lameness (EUR 1.07 to EUR 1.27 per cow-year). The total costs per case of ketosis, milk fever and metritis ranged from EUR 1.01 to EUR 1.30, EUR 1.14 to EUR 1.26 and EUR 0.95 to EUR 1.0, respectively. The highest economic values of dystocia were estimated for LROG (EUR −1.32), slightly lower for LBW (EUR −1.31) and LR (EUR −1.23). The results of this study show the importance of health traits to the economic features of cattle herd selection of new breeding goal and this would improve the herd health. The economic evaluation of the functional traits analyzed in this study indicated the significant economic importance of the functional traits in Lithuanian dairy cattle breeds.

Abstract. Bio-economic models for deriving economic weights in livestock have a significant development in recent years providing integrated assessment of biological and economic parameters of production systems and possibilities for achieving economic sustainability through inclusion in the selection index. Economic weights (EW) of traits have been calculated for different species of farm animals in the years. However, this review focuses on large ruminant aiming to summarize studies on calculation of economic values for dairy, beef and dual-purpose cattle. A method of research selection was used according to the productive direction (for milk, meat and dual-purpose), as well as according to the studied traits. In conclusion, it could be summarized that with regard to breeding objectives, economic weights of breeding traits need to be recalculated at certain time-periods and redefined in order to be relevant to the current market situations. Recently, there has been a tendency for functional traits to have an increasing economic influence and some of them should be included in the breeding goal. Moreover, the increased interest among customers in animal welfare and quality of dairy farm products will probably lead to the incorporation of health traits as clinical mastitis incidence and somatic cells score in the breeding objective. It is possible as well the relative importance of feed efficiency traits to increase in the future due to increasing requirements to mitigate the environmental impact of production systems.
