Summary: This study aimed to estimate heritabilities and genetic correlations among weekly body weight traits, Gompertz growth curve parameters, and feed efficiency characteristics in Japanese quails. The results showed high heritabilities for weekly body weight traits and moderate heritabilities for feed intake and feed conversion efficiency traits. The genetic correlations between feed intake and body weight traits were positive and moderate, while the genetic correlations between feed conversion efficiency and body weight traits were positive and strong. The study concluded that the negative genetic relationship between feed conversion efficiency and body weight may limit selection studies, and using the mature weight parameter as a selection criterion can enhance genetic gain.

Summary: In this study, the researchers investigated the effects of host genetics and gut microbiota on feed efficiency in laying hens. They found that genetic factors and gut microbiota both play important roles in determining feed efficiency, with RFI having the highest microbial influence. They also identified three microbial genera that were negatively correlated with RFI and positively contributed to improving feed efficiency.

Summary: This study estimated the genetic and phenotypic correlations between Aleutian disease (AD) tests and various traits in mink, including body weight, growth, and feed-related traits. The findings suggest that selecting AD tests does not have adverse effects on the growth, feed efficiency, and feed intake of mink. Additionally, the antigen-based enzyme-linked immunosorbent assay test could be considered a reliable and practical indicator trait for selecting AD-resilient mink on AD-positive farms.

Summary: The study identified phenotypic and genetic correlations between early-life feeding behaviors, dry matter intake, and feed efficiency with cow performance and lifetime productivity traits. These traits were also found to be related to cow weight, genetic factors, and calving interval.

Summary: Genetic parameters were estimated for various meat quality traits in commercial beef cattle. Heritability estimates were moderate for tenderness, palatability, and off-flavor, while other sensory traits had negligible or low heritabilities. Objective traits such as pH, intramuscular fat, and shear force had moderate heritability estimates. Genetic correlations between days for sensory traits were generally positive and high. The findings suggest that genetic selection based on objectively measured traits can improve meat quality and consumer satisfaction.

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: The study found that semen quality traits have a certain degree of heritability, and the moderate genetic and phenotypic correlations indicate the predictive value of these traits for service sire NRR. Selection for semen quality traits may be beneficial for improving service sire NRR.

Summary: The study found that HOL cows generally have higher heritability for DMI and DMIFor compared to SR cows, but the situation reverses in first parity. Heritability for DMI and DMIFor during the first parity averaged 0.11 and 0.15, while for ECMFor and ECM, the corresponding values were 0.21 and 0.29.

Summary: The profitability of the beef industry depends on the performance of both finishing cattle and the breeding herd. This study examines the inheritance of growth, ultrasound, and carcass traits in finishing beef cattle and their correlations with maternal performance traits. Results show that genetic variation exists in finishing animals, allowing for direct selection of enhanced growth, ultrasound, and carcass traits. Ultrasound scan traits are highly genetically correlated with corresponding traits measured at slaughter. Fat content in finishing cattle is positively correlated with rebreeding performance and negatively correlated with mature cow live weight. However, the correlation between genetic merit for carcass fat traits and body condition in mature cows is low.

Summary: Robustness refers to an animal's ability to overcome perturbations. Livestock breeding for production traits has led to reduced robustness, negatively impacting livability and production. There is a focus on improving robustness through poultry breeding by identifying novel phenotypes for selection. This study examined the genetic and phenotypic correlations of hypothalamic-pituitary-adrenal (HPA) axis activity traits with economically relevant traits in turkeys.

Summary: The improvement of feed efficiency in American mink is crucial for reducing the cost of production. This study estimated the heritability and genetic correlations of different feed efficiency measures and component traits. The residual intake and gain were found to be a favorable trait for selecting faster-growing mink with reduced feed intake. The Kleiber ratio was also identified as a promising indirect measure of feed efficiency. Overall, including feed efficiency traits in breeding programs can effectively select feed-efficient mink.

Summary: This study investigated the influence of genetic factors on feed efficiency and resilience traits in three purebred pig breeds. The results showed that feed efficiency and resilience traits were heritable, and there were no significant differences in genetic parameter estimates among the three breeds.

Summary: The study aimed to estimate genetic parameters for feeding behavior traits in growing cattle and investigate their associations with performance and feed efficiency traits. Results showed genetically heavier and faster-growing cattle had faster feeding rates and higher energy intake per feed event. However, including time-related feeding behavior phenotypes in a genetic evaluation for feed intake only marginally improved the precision of the estimated breeding values.

Summary: This study evaluated tick resistance in multiple beef cattle breeds, revealing differences in genetic correlations and heritability among populations, as well as the potential benefits of multi-trait genomic selection. The multi-trait approach improved predictive ability and corrected over-dispersion of GEBV, showing promise for enhancing tick resistance in beef cattle through genomic selection.

Summary: This paper reviews the literature on cattle breeding in tropical environments, particularly Indonesia. The aim is to find new breeding opportunities for smallholder farmers in Indonesia while conserving local cattle beef breeds. The lack of well-designed breeding programs in Indonesia has resulted in many mixed-breed animals with unknown genetic composition and adaptation capabilities. Crossbreeding programs are too complex for smallholder farmers, but within-breed selection could be used to develop tropically adapted composite breeds. International collaborations and the use of genomic information are crucial for genetic improvement and conservation of unique Indonesian cattle breeds.
