Genotype-by-environment interactions for feed efficiency traits in Nellore cattle based on bi-trait reaction norm models
CONCLUSIONS: Our results show evidence of G × E interactions on feed efficiency traits in Nellore cattle, especially in feeding trials with an average daily gain (ADG) that is far from the expected of 1 kg/day, thus increasing reranking of animals.PMID:38097941 | DOI:10.1186/s12711-023-00867-2 (Source: Genet Sel Evol)

Managing genomic diversity in conservation programs of Chinese domestic chickens
CONCLUSIONS: Conservation programs of three Chinese domestic chicken breeds have maintained their genomic diversity to a sustainable degree. The small ex situ conserved populations, which are maintained in controlled environments, retain less genetic diversity than populations conserved in situ. In addition, the transfer of populations from their place of origin to another site for conservation purposes results in genetic differentiation, which may be caused by genetic drift or adaptation. This study provides a basis for further optimization of in situ and ex situ conservation programs for domestic chicken breeds in China....

Genetic analysis of the blood transcriptome of young healthy pigs to improve disease resilience
CONCLUSIONS: These results suggest that expression levels in the blood of young healthy pigs for genes in biological pathways related to immunity and endoplasmic reticulum stress have potential to be used as genetic indicator traits to select for disease resilience.PMID:38087235 | PMC:PMC10714454 | DOI:10.1186/s12711-023-00860-9 (Source: Genet Sel Evol)

The genetics of gaits in Icelandic horses goes beyond DMRT3, with RELN and STAU2 identified as two new candidate genes
CONCLUSIONS: Our findings provide valuable information about the genetic architecture of pace beyond the contribution of the DMRT3 gene and indicate genetic interactions that contribute to the complexity of this trait. Further investigation is needed to fully understand the underlying genetic factors and interactions.PMID:38082412 | DOI:10.1186/s12711-023-00863-6 (Source: Genet Sel Evol)

Genetic parameters, reciprocal cross differences, and age-related heterosis of egg-laying performance in chickens
CONCLUSIONS: The heterosis was substantial for egg weight and cumulative egg number, and increased with age, suggesting that non-additive genetic effects are important in crossbreds between the indigenous and elite breeds. Generally, the crossbreds performed similar to or even outperformed the commercial White Leghorns for egg production persistency.PMID:38062365 | PMC:PMC10702067 | DOI:10.1186/s12711-023-00862-7 (Source: Genet Sel Evol)

A meta-analysis of genetic and phenotypic diversity of European local pig breeds reveals genomic regions associated with breed differentiation for production traits
CONCLUSIONS: In this study on European local pig breeds, we used a dedicated approach for detecting signatures of selection that were supported by phenotypic data at the breed level to identify potential candidate genes that may have adapted to different living environments and production systems.PMID:38062367 | PMC:PMC10704730 | DOI:10.1186/s12711-023-00858-3 (Source: Genet Sel Evol)

Impact of population structure in the estimation of recent historical effective population size by the software GONE
CONCLUSIONS: Different kinds of deviations from isolation and panmixia of the populations can generate biases in the recent historical estimates of Ne. Therefore, estimation of past demography could benefit from performing population structure analyses beforehand, by mitigating the impact of these biases on historical Ne estimates.PMID:38049712 | PMC:PMC10694967 | DOI:10.1186/s12711-023-00859-2 (Source: Genet Sel Evol)
