Sažetak
The objective of this study was to estimate the genetic parameters for calving ease of Simmental cattle in Croatia. Data consisted of 135, 892 calves, and pedigree included 639, 999 animals. Calving ease was scored from 1 to 5 (1= unassisted, 2 to 5= varios levels of assistance). Calving ease at first calving, and aecond or later parities where treated as different traits.Variance components were estimated by REML as implemented in VCE-5 package. Statistical model included age at calving, sex, region-year interaction as fixed effects and owner and direct additive genetic effect as random effects. The estimated heritabilities were 0.105 ± 0.005 for calvingease at first calving and 0.078 ± 0.005 for calving ease at second and later parities. These results suggest that model tested can be used for cattle evaluation for calving ease of Simmental cattle in Croatia.
