213 Distribution of subjectively evaluated conformation traits in commercial growing replacement gilts

Autor: Tom P Somrack, J. Holl, Kenneth J. Stalder, Grace Moeller, Courtney L Abell, W. O. Herring

Publikováno v: J Anim Sci

Feet and leg/locomotor issues represent a primary reason for sow removal from U.S. breeding herds. A shift from gestation stalls (GS) to group-sow housing (GSH) is occurring the U.S. swine industry, emphasizing the importance of structural soundness

Optimal definition of contemporary groups for crossbred pigs in a joint purebred and crossbred genetic evaluation

Autor: Bruno Valente, Ignacy Misztal, Yvette Steyn, W. O. Herring, J. Holl, D. A. L. Lourenco, Ching-Yi Chen

Publikováno v: Journal of Animal Science

In the pig industry, purebred animals are raised in nucleus herds and selected to produce crossbred progeny to perform in commercial environments. Crossbred and purebred performances are different, correlated traits. All purebreds in a pen have their

Publikováno v: J Anim Sci

Pooling semen of multiple boars is commonly used in swine production systems. Compared with single boar systems, this technique changes family structure creating maternal half-sib families. The aim of this simulation study was to investigate how pool

Most breeding companies evaluate economically important traits in males and females as a single trait, assuming genetic correlation of 1 between phenotypes measured in both sexes. This assumption may not be true because genes may be differently expre

Crossbreed evaluations in single-step genomic best linear unbiased predictor using adjusted realized relationship matrices1

Autor: W. O. Herring, Shogo Tsuruta, Daniela Lourenco, Ignacy Misztal, Ching-Yi Chen, Breno O. Fragomeni

Publikováno v: Journal of Animal Science. 94:909-919

Combining purebreed and crossbreed information is beneficial for genetic evaluation of some livestock species. Genetic evaluations can use relationships based on genomic information, relying on allele frequencies that are breed specific. Single-step

Crossbred evaluations using single-step genomic BLUP and algorithm for proven and young with different sources of data1

Autor: Ivan Pocrnic, Ching-Yi Chen, Ignacy Misztal, W. O. Herring, Daniela Lourenco

Publikováno v: Journal of Animal Science

Genomic selection (GS) is routinely applied to many purebreds and lines of farm species. However, this method can be extended to predictions across purebreds as well as for crossbreds. This is useful for swine and poultry, for which selection in nucl

Background The quantitative genetics theory argues that inbreeding depression and heterosis are founded on the existence of directional dominance. However, most procedures for genomic selection that have included dominance effects assumed prior symme

Publikováno v: Journal of Animal Science. 97:475-476

Computer vision systems (CVS) have many applications in livestock, for example, they allow measuring traits of interest without the need for directly handling the animals, avoiding unnecessary animal stress. The objective in the current study was to
