Summary: This study investigated the kinetics of muscle properties during ageing, aiming to propose an optimal duration for dry-ageing that balances between quality and meat weight loss reduction. The results showed changes in dry matter content, pH, color indices, and iron content with increasing ageing duration. Muscle tenderness decreased up to 35-days ageing, but cooking homogenized the tenderness of the samples regardless of ageing duration.

Summary: This study found that fresh beef tumbling did not significantly impact the quality and proteolysis of loins from cull cows. While tumbling did not affect initial loss, TS treatment resulted in higher moisture losses. Consumer panels preferred tumbled beef loins initially, but after additional ageing, this preference did not persist.

Summary: Adding octenyl-succinylated corn starch (Osan) significantly reduced cooking loss and dimensional shrinkage, while improving moisture retention, firmness, and color of ground beef patties. Sensory evaluation showed increased tenderness and juiciness with no significant alteration in flavor and color, indicating the potential benefit of using Osan in frozen patties in the meat industry. The overall sensory acceptability scores were high for patties containing Osan starch as well as native starch, with 15% animal fat also being favored.

Summary: The study found that cathepsin L is involved in the proteolysis of myofibrillar proteins both in vivo and in vitro. In vivo, cathepsin L promotes the degradation of desmin and troponin-T during postmortem aging. In vitro, cathepsin L facilitates the degradation of titin, nebulin, and troponin-T during incubation. However, cathepsin L does not cause the degradation of alpha-actinin and desmin, regardless of incubation temperature.

Summary: Consumer interest in grass-fed beef has been increasing, particularly in the western United States. This study aimed to evaluate the effect of feeding systems on the quality and sensory attributes of steaks during retail display. The results showed that different feeding systems had an impact on the color and oxidative stability of steaks, but did not affect the pH value or tenderness. Consumers and panelists did not detect any significant difference in taste or flavor between the different feeding systems.

Summary: Feeding a brassica cover crop mixture during the backgrounding phase did not impact beef palatability compared to a common dry lot backgrounding diet. However, steaks from the brassica cover crop group were found to be more tender on days 3 and 7, but no difference was observed on days 14 and 21. Further investigation into the mechanisms responsible for the differences in tenderness observed in instrumental analysis is recommended.

Summary: The study explored the relationship between genomic and phenotypic differentiation in response to divergent selection across different taxa, revealing a moderate association. This provides predictions for genomic and phenotypic adaptation by natural selection in natural populations, but further research is needed to link genomic differentiation to specific phenotypic traits. Improving correlations between genotypes and specific phenotypes through comprehensive studies on diverse populations within taxa and broad coverage of genomes and phenomes is suggested.

Summary: This study explores the influence of gut microbiota on feeding behavior traits and identifies specific microbes associated with these traits in three commercial swine breeds at different growth stages. The results indicate that the gut microbial composition explains a small to moderate proportion of the variability in feeding behavior. Several archaea and bacteria are found to be significantly correlated with feeding behavior measures. These findings highlight the importance of the gut microbiome in interacting with host feeding behavior and provide insights into swine microbial studies.

Summary: This study reveals the complex genetic architecture and genotype-by-environment interactions in wheat yield through the identification and evaluation of quantitative trait loci. The results show that the effects of these loci on spike yield and component traits vary across different environments, primarily due to contrasting effects on opposing traits. The structural equation model and path analysis provide a conceptual framework for understanding the interactions between yield genotype and environment in wheat.

Summary: The rumen microbiome plays a crucial role in methane emission in ruminants and has been the subject of extensive research in the past decade. High-throughput sequencing technologies have greatly expanded our knowledge of rumen microorganisms through metagenomic studies. Evidence shows that the composition of the rumen microbiota is influenced by the host's genotype, making modulation of the microbiota an important tool for breeding animals with lower emissions. This review discusses the challenges of metagenomic studies and proposes solutions, including incorporating metagenomic information into statistical models used in animal breeding. The latest advances in this field are also addressed.
