Integrated Multi‐Omics Analysis Reveals the Genetic Basis of Phenotypic Variation in Tibetan Sheep

Integrative Zoology, EarlyView.
SNaPshot‐validated GWAS results demonstrated significant correlations between candidate single nucleotide polymorphisms (SNPs) and body size traits in Tibetan sheep. Concurrently, hematoxylin and eosin staining, alongside muscle fiber analysis, confirmed pronounced morphological differences in muscle tissue between sheep of varying conformation.

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, EarlyView.
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.

Plasma Cortisol and Behaviour in Early Weaned Piglets

Acta Veterinaria Scandinavica, 1980
Comparisons were made of Cortisol concentration and behavioural activity between piglets weaned at 3 weeks of age (early weaned piglets), and piglets weaned at 8 weeks of age (control piglets). Early weaned littermates were placed in cages with a floor area of either 0.20 m2 per piglet or 0.15 m2 per piglet.

Genetic Control of Canalization for Twinning Rates in Polypay and Rambouillet Sheep Using Threshold or Double Hierarchical Generalized Linear Models

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In most sheep production systems, the ideal scenario is for every ewe to lamb and successfully raise twins. However, selection for increased number of lambs born (NLB) is often accompanied by a higher incidence of triplet and higher‐order births, which increases management challenges and producer reluctance to intensify selection for this ...

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Effects of Precision Feeding on Economic and Productive Yields of Hyperprolific Lactating Sows Allocated at Different Farrowing Pens

Animals
The results obtained using precision feeding in maternities (electronic sow feeders, ESFs) may be affected by the type of farrowing pen, as the design of the pen may modify the behavior of the sows.

Genetic Parameters for Feed Efficiency Indicator Traits in a Rotational Crossbreed Sow Population During Lactation Period

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The selection of feed efficient sows effectively converting feed into milk production and body weight gain will contribute to the overall profitability of pig farming systems. Consequently, the aim of the present study was to estimate genetic parameters for feed efficiency indicator traits during the sow lactation period, and to infer ...

Visceral organ growth and threonine utilization and requirements in the segregated early-weaned piglet

, 2004
This thesis is an investigation of the visceral organ growth and threonine (Thr) utilization and requirements in segregated early-weaned (SEW) piglets fed diets in which soybean meal (SBM) and corn provided the only sources of dietary proteins.

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.
