Use of multiple-trait animal models for genetic evaluation of milk, fat and protein lactation yields of dairy cattle in Belgium

Animals from embryo transfer may be included in the genetic evaluation of Simmental beef cattle in Brazil; this inclusion may provide potential gains in accuracy and genetic gains

Genetic correlation estimates for milk and fat yields indicate that sire ranking is not affected by HYSD herd environments where daughters make their records, but dif- ferences

We conclude that there is extensive genetic homogeneity in Holstein cattle in Córdoba Province and that it would be feasible to select for B alleles at the κ -casein and

In general, the inclusion of data from ongoing lactations and from lactations with non-conventional drying-off causes reduced the mean of predicted breeding values for 305-day

It is possible to see that the direct responses to accumulated yields are higher than all the correlated answers in the three traits analyzed, thereby indicating that the use of

We also show that the accuracy of predicting genetic values is higher for traits with a proportion of large effects (proportion black and fat percentage) than for a trait with no

The estimates of phenotypic and genetic correlations of weekly TD yields with 305-day milk yield was generally higher in the middle segment of lactation suggesting that these

The objective of this study was to estimate variance components and genetic parameters for accumulated 305-day milk yield (MY305) over multiple ages, from 24 to 120 months of age,
