Summary: This article reviews the research on the purebred-crossbred genetic correlation (rpc) in poultry and finds significant variations in rpc values across different traits. The existing studies might have overestimated rpc values. Future research should aim for more accurate rpc estimations and investigate the impact of genotype by environment interactions on rpc.

Summary: This study evaluates the performance of purebred and crossbred abalone strains under different culture modes in China. The results show that the H. discus hannai female × H. fulgens male (DF) strain has the highest growth performance, and the South-North (S-N) relay mode significantly improves the economically important traits of most strains.

Summary: The study derived expressions for the genetic correlation between purebred and crossbred performance based on genetic variances and genetic covariance between parental lines. Results showed that r(pc) decreases with increasing differences in allele frequencies between parental lines when non-additive effects are present. Genetic models involving dominance have lower values of r(pc) compared to models involving epistasis.

Summary: The study compared the welfare and performance of sows and piglets in three different farrowing systems, finding that the temporary crating system facilitated mother-young interactions but also resulted in a higher crushing rate. Sows exhibited different posture changes between systems and batches. Temporary crating did not alter the level of stress biomarkers in sows.

Summary: Canola plants have reduced crop yield and oil content under water-deficit conditions, especially during reproductive stages. This study analysed the genetic factors affecting seed yield and related traits in canola under well-watered and water-deficit conditions. The analysis revealed multiple genomic regions associated with flowering time, plant height, and seed yield under different water regimes. The study identified specific QTLs that were stable across environments and showed potential for improving water-use efficiency in canola breeding programs.

Summary: In moderate thermal conditions, crossbred cattle showed higher levels of heat production, thermal storage, and cutaneous evaporation compared to purebred Nellore cattle. Both genotypes were able to maintain their thermal balance with relatively low energy demand for thermoregulation.

Summary: This study proposes and compares three methods for approximating the required variance components, and validates that using REML estimates of variance components provides better predictions for r(pc) than methods based on GEBV.

Summary: The study compared the accuracy of genomic breeding values prediction in purebred and crossbred populations using different marker densities and imputation scenarios. Results showed that GBLUP method performed best in purebred populations with related reference population, while weighting mechanism led to highest accuracy in crossbred populations with low heritability traits.

Summary: This study aimed to quantify genetic variation in disease resilience using reaction norm models and identified genotype-by-environment interactions related to disease challenge loads. Results showed that selecting animals based on different levels of CL can improve their resilience, and high-performance animals can be selected at a given CL.

Summary: The study found significant environmental influences on the loin depth, backfat depth, and carcass growth of crossbred pigs, with genetic control of heat tolerance and genotype by environment interaction detected. The impact of heat stress and genotype by environment interaction varied across traits, with backfat depth showing higher heritability under comfortable conditions. The study highlights the importance of genetic resilience and performance under changing environmental conditions in swine.

Summary: This study investigates genotype by environment interactions of growth traits in razor clams reared in outdoor ponds and semi-natural environments. The results show significant genetic differences among families in different aquaculture environments. The heritabilities for growth traits are low to moderate, indicating that these traits can be effectively selected in both environments. This study provides guidance for breeding programs of razor clams in different aquaculture environments.

Summary: This study investigated the genetic and phenotypic background of energy reserves in Amur mirror carp and their impact on fish performance during the first winter. Results showed most traits related to energy reserves significantly decreased after the first winter, with differing genetic correlations and heritability before and after the winter. Interestingly, genetic correlations between HP glycogen traits and survival in the third growing season were positive, suggesting a genetically based strategy for energy mobilization in common carp. Monitoring FC and HSI could be useful for managing carp stocks.

Summary: This study investigated the relationships between off-flavor compounds, lipid contents, and fatty acids in rainbow trout reared in a recirculating aquaculture system (RAS). The results showed that fish with high lipid contents accumulated high concentrations of off-flavor compounds, but these compounds were negatively correlated with health-promoting fatty acids. Excessive lipid contents may reduce the nutritional value of the fish.

Summary: Carcass and fillet yields are economically important traits in aquaculture, and headless gutted carcass percentage (HC) is a convenient selection criterion. However, HC is a sib trait that cannot be recorded on selection candidates. This study compared different selection strategies for improving HC in rainbow trout breeding programs and found that a combination of genomic and indirect selection is the most effective approach.

Summary: This study demonstrates that selective breeding for improved resistance to columnaris disease in rainbow trout is feasible. A natural outbreak of the disease in a farm environment can be utilized to select fish with greater resistance, and genomic selection is an effective approach to expedite this process.

Summary: Improvement in feed conversion ratio (FCR) and reduction in nutrient loading in rainbow trout farming have significantly improved resource efficiency. Selective breeding has contributed to this improvement with an estimated genetic gain of 1.74% per generation in FCR. The use of genetically improved trout reduces feed and production costs.

Summary: This study conducted a comparative genetic analysis of the quantitative trait loci for resistance to warm water columnaris disease in two farmed rainbow trout populations. The results identified a major quantitative trait loci on chromosome Omy03 and a smaller quantitative trait loci on Omy05. These findings provide insights into the genetic basis of disease resistance and offer potential markers for breeding programs aiming to increase resistance against columnaris disease.
