Summary: This study identified candidate genes affecting subcutaneous fat deposition in beef cattle through genomics and transcriptomics analysis. Significant SNPs within or near 11 genes associated with backfat thickness were identified. Additionally, 13 overlapping genes related to fat deposition were determined. Finally, seven biomarkers associated with fat accumulation were screened. These findings provide novel insights into the regulation mechanism underlying bovine fat accumulation.

Summary: In ruminant livestock production, ruminal acidosis is caused by the high intake of starch-rich feed, leading to a state of subacute acidosis (SARA) and eventually acute acidosis due to lactate accumulation. This study identified two bacterial operational taxonomic units (OTUs) enriched from rumen fluid cultures, Bt-01708_Bf and Bt-01899_Ap, which can metabolize lactate into distinct subgroups based on other metabolic capabilities. The genomic analysis revealed the presence of lactate dehydrogenase, lactate transporter, and pathways for short chain fatty acids production and glycogen synthesis in these bacterial species.

Summary: This study verified the relationship between the expression of ACSF3 and cellular triglyceride production, and analyzed the relationship between ACSF3 polymorphism and economic traits and fatty acid composition in Chinese Simmental cattle. ACSF3 plays a crucial role in regulating cellular triacylglycerol and long-chain polyunsaturated fatty acid levels, and polymorphism could serve as a useful molecular marker for marker-assisted selection in beef cattle breeding for intramuscular fat deposition traits.

Summary: This study compared the blood transcriptomes of two distinct populations of post-weaned beef cattle, with and without developing bovine respiratory disease (BRD) within 28 days of arrival. A total of 132 unique differentially expressed genes (DEGs) were identified between groups stratified by disease severity, providing insights into potential biomarkers and functional mechanisms for predicting BRD development and severity. ROC curves generated from expression data of six specific genes showed good-to-excellent predictability for classifying disease occurrence and severity, highlighting their potential in clinical application for BRD management.

Summary: This preliminary study aimed to verify the association between MAP infectious status and the presence of single nucleotide polymorphisms (SNPs) in candidate genes in Italian Marchigiana beef cattle. A longitudinal study was conducted, analyzing DNA samples from 112 bovines and focusing on the differences in genotypic frequencies of the candidate genes IL10RA and IL12RB2. The results revealed potential resistance traits to PTB in the Marchigiana breed, as SNP genotypes associated with PTB resistance were found more frequently.

Summary: The measurement age of a longitudinal trait and pre-sampling procedures in beef cattle herds can influence the identification of functional candidate genes associated with a trait. Different genes may play a more significant role in body weight at various ages, and sequential sampling can affect the results of genome-wide association studies for longitudinal traits.

Summary: This study analyzed the genomic data of 441,802 Holstein cattle and identified 604 chromosomal regions showing significant transmission ratio distortion (TRD). The majority of these regions exhibited allelic TRD patterns, with reduced viability for carrier offspring or lethality for homozygous individuals. Functional analysis also revealed candidate genes related to embryonic development, DNA repair, and meiotic processes. These findings have implications for improving breeding success in cattle.

Summary: This study evaluated the genotype x environment interaction for scrotal circumference measured at different ages in Brahman bulls. Weak evidence of GxE effect was found at 12 and 18 months, recommending these ages for selection. No changes in sire rankings were observed across environments, making selection more straightforward at these ages.

Summary: This study found that supplementation of fetal bovine serum (FBS) in embryonic culture medium can affect cell differentiation during early bovine embryo development. Absence of FBS reduces blastocyst rates, but there is no reduction when 33% volume renewal of the medium is done at 90 hours post insemination. Additionally, FBS supplementation alters the allocation of trophectoderm (TE) and primitive endoderm cells.

Summary: This study analyzed the impact of castration on the expression of genes in skeletal muscles and the quality of beef. Results showed that castrated steers had increased expression of genes related to fat metabolism compared to intact bulls. This led to higher intramuscular fat content and different fatty acid profiles in the beef produced by steers and bulls. Despite a 180-day feeding period, crossbred bulls did not exhibit substantial increases in intramuscular fat or improved fatty acid profile compared to steers.

Summary: Significant progress has been made in the genetic improvement of livestock species, particularly through genomics and predicting breeding values. This study aims to estimate individual genomic inbreeding coefficient and identify runs of homozygosity and heterozygosity throughout the genome of Quarter Horse racing line. Moderately high genomic inbreeding was observed, with candidate genes related to crucial biological processes and muscle disorders identified. These findings have important implications for selecting animals with regenerative capacity and developing treatments for muscle disorders.

Summary: The objective of this study was to evaluate the effects of different nutritional strategies on reducing enteric methane emission in feedlot sheep using meta-analytical methods. The results showed that lipid inclusion in diets had the greatest effectiveness in reducing methane emission, followed by tannins. Rumen defaunation and essential oils inclusion had no effect on methane production. Further studies are needed to confirm the effects of saponins and nitrate supplementation on methane emission.

Summary: Molasses is commonly used in the diet of ruminant animals, but its effect on carcass parameters is not well-established. This study aimed to evaluate the impact of molasses inclusion in the diet of feedlot cattle on performance and carcass parameters. Thirteen peer-reviewed publications with 45 treatment means were analyzed, and the effect of molasses on beef cattle diets was assessed through weighted mean differences. The findings showed that the inclusion of molasses improved dry matter digestibility but reduced NDF digestibility, carcass weight, subcutaneous, and visceral fat. The level of molasses inclusion and the experimental period were the main factors influencing the responses.
