Summary: The milk differential somatic cell count (DSCC) has been proposed as a means to monitor udder health status (UHS) in dairy cows. The study analyzed milk test-day records of different cow breeds to identify factors affecting DSCC and SCC variability. Udder health-related traits (SCS and DSCC) were found to be useful in improving individual cow and herd udder health. The combination of SCS and DSCC is also useful in monitoring milk yield and composition.

Summary: The study found associations between differential somatic cell count and milk quality and cheesemaking traits. High DSCC was positively correlated with the recovery of protein, fat, and energy in milk, while high MAC count was negatively associated with milk quality.

Summary: The study aimed to estimate the genetic parameters related to milk urea content (MU) and its relationship with other milk traits in dairy cows. The results showed moderate heritability estimates for MU, indicating its potential as a selectable trait for reducing nitrogen emissions. However, further research is needed to establish the relationship between MU as an indicator trait and the target trait of total individual nitrogen emissions.

Summary: This study investigated the associations between subclinical intramammary infection (IMI) from different pathogens and inflammation status, as well as a set of blood biochemical traits. The results showed significant associations between somatic cell count, bacteriological status, and blood metabolites, liver function, oxidative stress, inflammation, innate immunity, and mineral status.

Summary: In this study, BoLA-DRB3 genotyping was performed in 59 EBL cattle younger than 3 years and 69 EBL cattle older than 3 years. The BoLA-DRB3*15:01 allele was identified as a susceptibility allele for early EBL onset. The BoLA-DRB3*15:01/*15:01 and BoLA-DRB3*15:01/other genotypes were found to be early EBL onset susceptibility genotypes.

Summary: Mastitis in dairy cattle can result in significant financial losses, including reduced milk yield, the inability to sell milk during the withdrawal period after treatment, and reduced commercial value due to increased somatic cell count. This study conducted a cross-sectional survey on 208 dairy cattle farms in Chiang Mai, Thailand, aiming to identify risk factors associated with high somatic cell count (SCC) and assess the economic impact of high SCC. The findings revealed that inappropriate vacuum pressure and pulsation rate of milking machines were significant risk factors for high SCC, and treating affected cows was found to be more cost-effective than culling. The average economic loss in affected farms was estimated to be 557 USD for three months.

Summary: Milk oligosaccharides (MOs) and fatty acids (MFAs) have prebiotic, antiadhesive, and antimicrobial effects. Their relationships with milk microbes and inflammation have been studied in humans, but not in cows. Studying the relationships among milk microbiota, MFAs, MOs, lactose, and somatic cell counts in cows can provide valuable insights for improving milk quality and reducing waste.

Summary: This study investigated the impact of heat stress on somatic cell score (SCS) of Holstein dairy cattle through random regression models using temperature-humidity index (THI) and diurnal temperature variation (DTV). The findings showed that including THI and DTV as fixed effects in the model considering the two days average improved estimated breeding values (EBVs) and the reliability of EBVs, demonstrating the sensitivity of Holstein dairy cattle SCS to heat stress.

Summary: Autochthonous Sudanese cattle breeds, such as Baggara, Butana, and Kenana, are known for their adaptability and high performance in hot and dry conditions, which makes them popular among nomadic and semi-nomadic pastoralists. Analysis of the genetic diversity of the BoLA-DRB3 gene in these breeds revealed unique alleles and patterns of genetic selection. The results suggest that these indigenous cattle have evolved to thrive in Sudan's harsh environment, showing resistance to tropical diseases and high reproductive capacity.

Summary: This study identified chromosomal loci and candidate genes affecting milk production phenotypes in a Korean Holstein population through a genome-wide association study. Three main candidate genes were discovered, providing insights into the genetic and molecular mechanisms underlying milk production traits. The research also found significant SNPs and genetic regions associated with milk production traits, suggesting a strong relationship between candidate genes and physiological mechanisms related to fat production in Korean Holstein cattle.

Summary: Human milk oligosaccharides (HMOs) are important components in breast milk with various health benefits for newborns, while most infant formulas lack these oligosaccharides. The diversity and concentration of oligosaccharides in mammalian milk vary among species, and sialylated milk oligosaccharides (SMOs) are gaining attention in research due to their beneficial nature.

Summary: In this study, a combination of Loop-Mediated Isothermal Amplification (LAMP) and PCR techniques with high-resolution melt (HRM) curve analysis were used to analyze different bacterial species and clinical samples. HRM curve analysis genotyped all clinical samples into three distinct groups based on differences in melting curve profiles, which reflected DNA variation in the sorD gene. A mathematical model based on Genetic Confidence Percentage (GCP) and a cut-off point value were established for HRM curve analysis, enabling differentiation of S. zooepidemicus isolates without visual interpretation of curve profiles. PCR-HRM and LAMP assay showed high accuracy in detecting S. zooepidemicus, with PCR-HRM having a turnaround time of six hours and LAMP assay requiring 120 minutes compared to the minimum three days for routine bacterial culture method. These rapid diagnostic tests can benefit mares suspected of endometritis by allowing early detection of S. zooepidemicus and proper treatment before breeding, reducing unnecessary treatment and antibiotic resistance.
