A comparison of Nordic Red, Holstein-Friesian and Finnish native cattle bulls for beef production and carcass traits

摘要

The objective of this study was to determine beef production traits of purebred Nordic Red (NR), Holstein-Friesian (Hol), Eastern Finncattle (EF), Northern Finncattle (NF) and Western Finncattle (WF) bulls. The data collected from slaughterhouses included observations of 164 862 NR, 87 323 Hol, 283 EF, 523 NF and 1 728 WF bulls. For estimating valuable cuttings also a separate dataset was collected including observations of 16 036 NR, 8 806 Hol, 18 EF, 126 NF, and 133 WF bulls. NR and Hol had the highest carcass gain (532 and 542 g d-1, respectively). Overall, the data showed poorer gain of the Finnish native breeds compared to NR and Hol. Among the native breeds, WF (427 g d-1) showed better growth compared to EF (356 g d-1) and NF (385 g d-1).?? Less differences were observed in valuable cuttings as might be inferred based on the differences in carcass conformation scores.
