Genetic parameters between feed-intake-related traits and conformation in 2 separate dairy populations-the Netherlands and United States
C.I.V. Manzanilla-Pech,Roel F. Veerkamp,Robert J. Tempelman,M.L. van Pelt,Kent A. Weigel,Michael J. VandeHaar,T.J. Lawlor,D.M. Spurlock,L.E. Armentano,C.R. Staples,Mark D. Hanigan,Y. de Haas +11 more
TL;DR: Feed-intake-related traits were moderately to highly genetically correlated with conformation traits (ST, CW, BD, and BCS) in both countries, making them potentially useful as predictors of DMI.
Journal ArticleDOI
Genetic analysis of longevity in Dutch dairy cattle using random regression
TL;DR: In this article, a random regression model with second-order Legendre polynomials was fitted for the additive genetic effect to evaluate the survivability of dairy cows, and the authors investigated whether these methods also need to take account of survival being a different trait across the entire lifespan of a cow.
Journal ArticleDOI
Evaluation of classifiers that score linear type traits and body condition score using common sires
TL;DR: To ensure that classifiers rank animals consistently, i.e., the repeatability between classifiers and within classifier, genetic links across routinely scored observations may be used to validate scoring of individual classifiers.
Journal ArticleDOI
Combining cow and bull reference populations to increase accuracy of genomic prediction and genome-wide association studies
TL;DR: The developed bivariate Bayesian stochastic search variable selection model allowed for an unbalanced design by imputing residuals in the residual updating scheme for all missing records, and was able to analyze 2 traits, even though animals had measurements on only 1 of 2 traits.
Journal ArticleDOI
Breeding for polledness in Holstein cattle
TL;DR: Using optimal contributions and a combination of polled and horned bulls, a next generation of animals can be bred that combines a high genetic merit with a relatively low relatedness and higher frequency of polledness.
