Abstract: The objective of this study was to estimate genetic parameters for survival measures from birth to 60 and 72 months of age, as well as survival up to 48 and 54 months after first calving. The genetic association of these measures with 20 linear type traits and final score in Holstein cows, born between years 1990 to 2004, was also evaluated. The components of (co)variance were estimated by Bayesian methods, using the programme THRGIBBS1F 90 in bivariate analyses, considering animal threshold model for measures… Show more

“…Boettcher, Jairath, and Dekkers () and Kern et al. () used threshold models for Canadian and Brazilian Holsteins, respectively, whilst numerous other studies have used linear models (e.g. Wiebelitz, Reinhardt, Liu, Erbe, & Simianer, ; Zavadilová & Štípková, ; Zavadilová, Štípková, Němcova, Bouška, & Matějičkova, ).…”

“…Heritability estimates in dairy cattle breeds were generally low, ranging from 0.04 (Holtsmark et al, 2009) to 0.15 (Kern et al, 2014). Estimates in beef cattle breeds, however, were higher, ranging from 0.08 (Van Westhuizen et al, 2001) to 0.30 (Maiwashe et al, 2009) probably owing to differences in trait definition between dairy and beef cattle.…”

“…Heritability for longevity has been estimated with TMs in Canadian Holsteins (Boettcher et al, 1999), Spanish Holsteins (Gonzalez-Recio & Alenda, 2007), South African beef cattle (Van Westhuizen et al, 2001), South African Angus (Maiwashe et al, 2009), Norwegian Red (Holtsmark et al, 2009) and Brazilian Holsteins (Kern et al, 2014). Heritability estimates in dairy cattle breeds were generally low, ranging from 0.04 (Holtsmark et al, 2009) to 0.15 (Kern et al, 2014).…”
