Heritability of Productive, Reproductive and Carcass Traits in Pure‐Bred and Cross‐Bred Pigs: A Systematic Review and Meta‐Analysis

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Heritability (h2) is a key parameter in animal breeding, but its magnitude and consistency across pure‐bred (PB) and cross‐bred (CB) pig populations remain poorly understood. This study aimed to compare heritability estimates between PB and CB populations for economically relevant traits through a systematic review and meta‐analysis.

Genetic background of body reserves in laying hens through backfat thickness phenotyping [PDF]

In this study, we pursued three primary objectives: firstly to test and validate the phenotyping of backfat thickness as an indicator of the overall fatness of laying hens; secondly, to estimate genetic parameters for this trait; thirdly, to study the ...

Genome‐Wide Association Studies for Anogenital Distance and Linear Type Traits in Gir Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Although linear type traits have been under selection in the Dairy Gir cattle for the past three decades, there are few studies exploring genetic architecture for these traits. The aim of this study was to identify candidate genes for anogenital distance and linear type traits in the Gir breed. For this study, the body measures of rump length (

Long Non‐Coding RNAs: Key Regulators of Economic Traits in Livestock From Mechanisms to Breeding Applications

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Long non‐coding RNAs (lncRNAs) act as key regulators of economically important traits in livestock through diverse mechanisms including ceRNA networks, epigenetic regulation (X‐inactivation and imprinting) and liquid–liquid phase separation (LLPS).

Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

Journal of Animal Breeding and Genetics, Volume 143, Issue 6, Page 746-761, November 2026.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

Molecular characterisation of QTLs controlling fatness in pigs [PDF]

, 2002
This thesis deals with the identification of genes controlling intramuscular fat and backfat thickness. Markers linked to quantitative trait loci (QTL) for these traits in the cross between Meishan x Large White breeds will lead to the identification of ...

Effects of Gestational Housing on Reproductive Performance and Behavior of Sows with Different Backfat Thickness [PDF]

Asian-Australasian Journal of Animal Sciences, 2015
The present study investigated the effects of back-fat thickness at d 107 of gestation and housing types during gestation on reproductive performance and behavior of sows. A total of 64 crossbred sows (Landrace×Yorkshire) in their 3 to 4 parities were allotted to one of four treatments (n = 16) over two consecutive parities.

Backfat thickness during gestation and lactation period in respect to reproductive performance of primiparous and multiparous sows [PDF]

Journal of Central European Agriculture, 2015
The aim of the study was to determine the effect of backfat thickness measured during gestation and after lactation of primiparous and multiparous sows on the value of reproductive traits.
