Summary: This study discovered selection signatures in Canchim composite beef cattle through genomic analysis. Most of the identified genes were found near the expected functional genes in the breeding program, which are associated with meat quality and reproductive traits. Additionally, genes related to immunity, adaptation, morphology, and behavior were also identified. Some recently introduced genes in Canchim, such as those related to polled trait, were also identified.

Summary: The study compared the accuracy of read mapping and variant genotyping between the bovine reference genome (ARS-UCD1.2) and a highly continuous Angus-based assembly (UOA_Angus_1) using whole genome sequencing data of 161 Brown Swiss cattle. While differences in read mapping and genotyping accuracy between both assemblies were minimal, the choice of the reference genome significantly impacted the detection of selection signatures. A workflow was developed for comparing the impact of reference genomes on genome analyses in various breeds, populations, and species.

Summary: The study found that meat from older animals required higher temperature and prolonged cooking to achieve equal tenderness compared to meat from younger animals. Cooking time, temperature, and their interaction significantly affected cooking loss in both muscles. In sous vide cooking, the solubilization of collagen contributed to the improved tenderness of the muscles.

Summary: Mesophyll conductance (g(m)) is a crucial factor in limiting photosynthesis, yet its response to long-term growth in variable [CO2] conditions depends on water stress, particularly in crop plants. Plants with higher g m may increase photosynthetic rates (A) without increasing stomatal conductance (g(sc), thereby improving water-use efficiency (WUE).

Summary: Genotypic errors can impact the accuracy of genomic predictions and genomic relationship matrix, but their influence may not be substantial across different datasets. Increasing SNP density from 3 to 20 K can marginally enhance the accuracy of genomic predictions using the current population and genomic parameters.

Summary: The study found that injecting ginger proteases and using sous vide cooking can significantly improve the tenderness of beef muscles, but an overly long cooking time may result in the meat becoming excessively tender. Injection of ginger proteases and longer cooking times can reduce the juiciness of the meat, while also increasing the content of soluble collagen.

Summary: This study showed significant differences in liveweight between morning and afternoon, with more fluctuations in afternoon liveweight. Smoothing of automatically-collected data reduced variability in liveweight, liveweight change, and dry matter intake. Adjusted liveweight values led to more accurate estimation of dry matter intake for dairy cows.

Summary: Estimating heritability based on individual phenotypic and genotypic measurements can be expensive and labour-intensive in commercial aquaculture breeding. This study investigated the feasibility of estimating heritability using within-family means of phenotypes and allelic frequencies. The results showed that at least 200 families of 60 progeny per family divided equally in two pools per family were required to effectively estimate the heritability of family means. Increasing the size of pools resulted in increasing the heritability of family means towards one.

Summary: This study examined the correlation between lactate dehydrogenase (LDH) and serum albumin (SA) in milk and the transfer of IgG, as well as their ability to differentiate between gram-positive and gram-negative intramammary infections (IMI). The results showed that both LDH and SA could predict the transfer of IgG, and when combined with somatic cell count (SCC), they could accurately differentiate between the two types of IMI. The study also found that the measured factors had higher values in milk samples taken before milk ejection.

Summary: This study investigated the plant growth and responses of the microbial profile in the rhizosphere soil and root endosphere of avocado plants infested or not infested with Phytophthora cinnamomi. The findings showed that applying phosphite or mineral mulch to the soil can reduce root growth and visible root damage in infested plants. Bacterial abundance and diversity were reduced in the infested rhizosphere and root endosphere, but the presence or absence of mineral mulch resulted in greater diversity and larger differences in rhizosphere community composition. Actinobacteria and Proteobacteria had higher abundance in the presence of Phytophthora. The addition of silicate-based mineral mulch can protect against Phytophthora root rot through changes in rhizosphere bacterial community composition, while the changes induced by spraying plants with phosphite are different from those resulting from the application of mineral mulch to the soil.

Summary: Sialic acids (Sias) derived from red meat, including Neu5Ac and KDN, have various roles in immunity and brain cognition, while Neu5Gc may increase the risk of cancer and inflammation. A study using UHPLC determined the content of Neu5Ac and KDN in skeletal muscle and organs of different species, revealing that goat skeletal muscle had the highest Neu5Ac content, followed by kidney. This study provides guidance for consumers to choose red meat with lower Neu5Ac and Neu5Gc content.
