Direct and maternal genetic relationships between calving ease, gestation length, milk production, fertility, type, and lifespan of Holstein-Friesian primiparous cows
2013, Journal of Dairy ScienceCitation Excerpt :This was a consistent trend across a variety of dairy traits in the current study; thus, it cannot be ruled out that this phenomenon is an artifact of the fitted model. However, the fact that most of the genetic parameters yielded by this model were in line with estimates in literature (Brotherstone et al., 1990; Cue et al., 1990; Berry et al., 2004; Wall et al., 2005; López de Maturana et al., 2007a), which were obtained by a variety of statistical models, speaks strongly for its robust validity. It has also been demonstrated in the current study that not all previously observed associations of selection traits with CE and GL have a direct genetic basis.
Technical note: Prediction of liveweight from linear conformation traits in dairy cattle
2012, Journal of Dairy ScienceCitation Excerpt :Comparison criteria included the average absolute difference, root mean square error, and product-moment correlation. ( Co)variance estimates between liveweight and conformation traits were calculated with a multivariate model that included effects similar to the UK national genetic evaluation model for conformation traits (Brotherstone et al., 1990). Thus, year-season of inspection, age of cow at inspection (linear regression), stage of lactation at inspection (linear and quadratic regression), and month of calving were fitted as fixed effects.
Animal muscularity and size are genetically correlated with animal live-weight and price
2012, Livestock ScienceCitation Excerpt :Gutierrez and Goyache (2001) using Asturiana de los Valles beef cattle from Spain reported similar heritability estimates to those found in the present study for body condition score (0.33; Table 2) and all common skeletal type traits that were evaluated in this study (0.11 to 0.23; Table 2). Although heritability estimates of functional traits are lacking in beef cattle the lower heritability of the functional type traits (0.05 to 0.13; Table 2) in the present study compared to the skeletal and muscular type trait is consistent with previous studies in dairy cattle (Brotherstone et al., 1990; Meyer et al., 1987; Short and Lawlor, 1992). Heritability estimates for the linear type traits in the present study are also similar to other production traits in beef cattle such as live-weight (Meyer et al., 1993), auction price (Mc Hugh et al., 2011; Schierenbeck et al., 2008), and average daily gain (Crowley et al., 2010).
