A large-effect locus on chromosome 4 underlies circadian feeding rhythmicity in pigs

Wim Gorssen, Naveen Kumar Kadri, Xena Marie Mapel, Alexander S. Leonard, Qiongyu He, Carmen Winters, Negar Khayatzadeh, Claudia Kasper, Hubert Pausch

This study identifies a QTL on chromosome 4 associated with circadian feeding rhythmicity in pigs, linking it to genes involved in feeding behavior and energy homeostasis.

Integrating three genetic dimensions relating to piglet birth weight: direct and maternal effects on the mean and genetic control of residual variance

Ewa Sell‐Kubiak, Claudia Kasper, A.A. Lepori, Juan Pablo Gutiérrez, Nora Formoso‐Rafferty, Negar Khayatzadeh, I. Cervantes

This paper estimates direct and maternal genetic effects on piglet birth weight and its variability, finding maternal effects are crucial while direct effects are negligible.
