Sentence examples for use a sire model from inspiring English sources
Therefore, we decided to use a sire model implementation, because it is more robust than the animal model implementation with DHGLM when animals only have a single observation.
A simulation using a sire model was carried out to investigate methods of analyzing binary data with ECP.
These CDs were low when the genetic evaluation was done using a sire model, even for highly heritable traits.
A simulation using a sire model was used to test the effect of the g-prior in the presence of ECP.
In such a case, the data were simulated using an animal model with pedigree but the genetic evaluation was done using a sire model.
This average CD was about double than that obtained using a sire model with unknown and known pedigree (0.22 and 0.24, respectively).
Instead of using an animal model, we used a sire model because implementation of the animal model DHGLM resulted in severely biased estimates of variance components with single observations per animal.
De los Campos et al. [ 14] have compared four SEM specifications to study relationships between somatic cell score (SCS) and milk yield (MY) in first-lactation Norwegian Red cows using a sire model.
Half-sib ANOVA analysis of LEPG using a sire model highlighted the extreme significance of the sire effect (p < 4 × 10-14), but led to a comparably low h2 estimate of 0.09 assuming that the correlation between half-sibs ("intraclass correlation") equals h/4 (e.g. [ 41]).
Using a sire model, the percentage of connected herds was very low even for highly heritable traits whereas with an animal model, most of the herds of the breed were well connected and high CD values were obtained among them, especially for highly heritable traits (the mean of average CD per herd was 0.535 for a simulated heritability of 0.40).
The percentage of connected herds using a sire model was very poor even for highly heritable traits (Table 4), while, the degree of connection evaluated with an animal model was important for moderately and highly heritable traits but still poor for lowly heritable traits.
