Summary: The position an individual holds in a social network is influenced by both direct and indirect social interactions. The genotype of individuals within a social group impacts their network positions, and studying how genetic effects shape social network positions is crucial for understanding social environment and evolution.

Summary: Understanding the origin and propagation of individual differences is essential in biology. This study demonstrates that indirect genetic effects (IGE) can influence the phenotypes of individuals who do not personally experience them. Genetically different social environments led to differences in aggression levels and these effects carried over to influence the behavior of naive individuals in new social groups.

Summary: This study investigated the effects of breeding methods, housing environments, coping styles, and gender on the metabolome profile of pigs. Results showed that positive and negative IGE animals exhibited different metabolic responses to a regrouping test, with significant changes in amino acids metabolism.

Summary: This study aimed to estimate genetic parameters for stayability to consecutive calvings in Angus/Brangus and Hereford/Braford cattle breeds. The heritability estimates ranged from 0.05 to 0.08, with stayability being higher at intermediate calvings. Genetic correlation estimates suggested that the genetic control of stayability to each calving is performed at least partially by the same group of genes.

Summary: Genetic parameters for sow stayability were estimated from farrowing records of Landrace and Large White sows, showing differences in heritability and genetic correlations among parities between breeds and models. The study also found that selection for number born alive does not necessarily reduce sow stayability, with results possibly influenced by culling decisions made by farmers.

Summary: The present study aimed to investigate the association between stayability traits, muscularity, and body condition score (BCS) in Italian Simmental dual-purpose cows. The results showed that cows with a medium BCS and muscularity in early lactation had a higher likelihood of staying in the herd compared to thinner ones. However, cows with high muscularity were less likely to start the third lactation, indicating a potential preference for market cows with good conformation for meat purpose. This study highlights the importance of muscularity and BCS early in life for the stayability of Simmental cows.

Summary: Genes not only control traits, but also shape the environment and phenotypes of social partners. The effects of genes on social partners can have profound consequences and alter heritability and trait evolution. Empirical research shows that IGEs can explain a large proportion of trait variation. However, the general prevalence of IGEs is still not well understood.

Summary: This study successfully identified significant indirect genetic effect loci between peers using a dataset of genetically heterogeneous laboratory mice. There was no overlap observed between these loci and direct genetic effect loci for the same phenotype, and fine mapping was conducted on several key IGE loci. Experimental manipulation confirmed that the Epha4 gene contributes to stress coping strategy and wound healing via indirect genetic effects.

Summary: This study investigates the role of genetic variance in shaping affiliative behaviors in the Amboseli wild baboon population. The results show that grooming behavior in female baboons is heritable and influenced by environmental factors such as dominance rank and the availability of kin as grooming partners. There is also a small but measurable genetic effect of partner identity on grooming behavior.

Summary: Research on 80,889 European couples reveals that approximately 25% of analyzed traits show evidence of partner heritability consistent with indirect genetic effects, impacting traits such as dietary habits, mental health, and disease. These findings indicate that the environment linked to complex traits can be partially explained by the genotype of other individuals, suggesting the importance of exploring new ways to study environmental influences.

Summary: Genetic parameters of calf health traits in organic US Holstein calves were estimated in this study, with heritability estimates of 0.100 for respiratory disease, 0.075 for scours, and 0.085 for stayability. There was a moderate favorable genetic correlation between respiratory disease resistance and stayability (0.675).

Summary: The genetic parameters and correlations for feed efficiency, growth, and carcass traits in Hanwoo cattle were estimated. Heritability estimates were moderate for feed efficiency and growth traits, but tended to be higher for carcass traits. Feed efficiency traits were positively correlated with all carcass traits, while growth traits showed varying genetic correlations among each other.

Summary: This study estimated genetic parameters for yearling ultrasound and carcass traits in Hanwoo cattle, revealing moderate to high heritability estimates and favorable genetic correlations between carcass traits and their corresponding ultrasound measurements. The results suggest that genetic improvement for carcass traits can be achieved by using yearling ultrasound measurements as selection criteria in Hanwoo breeding programs.

Summary: This study compared the prediction accuracy of conventional pedigree-based BLUP and single-step genomic BLUP methods for 10 primal cut traits in Hanwoo cattle, with ssGBLUP showing better performance overall. The ssGBLUP method demonstrated more accurate and less biased predictions across the studied traits, making it more suitable for improving accuracy in predicting primal cut yields.

Summary: This study investigated the genetic diversity and inbreeding level of a Korean synthetic pig breed, Woori-Heukdon (WRH; F3), and its parental breeds. The results showed that WRH was genetically influenced by its parental breeds and had a lower level of inbreeding compared to the parental breeds. Additionally, gene annotation of ROH islands in WRH identified candidate genes associated with adaptation, meat quality, production, and reproduction traits in pigs.

Summary: Three-dimensional point cloud generation systems from scanning data of a moving camera provide additional information about an object besides color. It has applications in animal husbandry to improve fertility and milk production efficiency. However, traditional stereo matching algorithms used in depth image generation have drawbacks, such as poor-quality depth images and missing information in overexposed regions. This study proposes an integrated system using two cameras to overcome these limitations.
