Autor: M. Schmid, A. Imort-Just, R. Emmerling, C. Fuerst, H. Hamann, J. Bennewitz

Publikováno v: Animal, Vol 15, Iss 1, Pp 100052- (2021)

The production environments of the German–Austrian Brown Swiss population show a wide range due to differences in topography, landscapes, local climates, and different farm management systems. Extensive production systems such as organic farming ha

Invited review: Genome-wide association analysis for quantitative traits in livestock – a selective review of statistical models and experimental designs

Autor: M. Schmid, J. Bennewitz

Publikováno v: Archives Animal Breeding, Vol 60, Pp 335-346 (2017)

Quantitative or complex traits are controlled by many genes and environmental factors. Most traits in livestock breeding are quantitative traits. Mapping genes and causative mutations generating the genetic variance of these traits is still a very

The presence of extreme feather peckers in groups of laying hens

Autor: H.-P. Piepho, V. Lutz, J.B. Kjaer, M. Grashorn, J. Bennewitz, W. Bessei

Publikováno v: Animal, Vol 11, Iss 3, Pp 500-506 (2017)

Feather pecking is a serious economic and welfare problem in laying hens. Feather damage occurs mainly through severe feather pecking (SFP). Selection experiments have proved that this behavior is heritable and lines have been divergently selected fo
