Summary: Indoor housed dairy cows are highly motivated to scratch themselves using mechanical brushes. Many farms provide brushes to cows, yet no commercial brushes to date capture how the brushes are used by the cows in the pen. We developed an automated brush and tested how much cows use it at four different group sizes (60, 48, 36, and 24 cows) and with different brush locations in the pen. We found that cows used the brush for longer when it was close to the feed and water and when they were housed in smaller groups.

Summary: Consumers are increasingly choosing organic farming products because they believe that organic farms do not use pesticides or antibiotics and that animals are provided with the best living conditions. This review discusses the comparison between organic and conventional dairy cattle housing systems in terms of welfare assessment, breed selection, and product quality. It has been shown that cows kept in organic systems usually have better welfare compared to conventional breeding, but conventional farms can also provide better animal welfare through the use of pasture grazing. The taste of milk is affected by pasture feeding, but this depends on consumer preference.

Summary: Lying down is crucial for dairy cow welfare, as cows are highly motivated to lie down and may exhibit indicators of frustration when unable to do so. Environmental factors and health conditions play a significant role in influencing lying time, and the implications on welfare remain complex and multifaceted. More research is needed to fully understand the relationship between lying behavior and animal welfare.

Summary: The study aimed to develop new recommendations for tie-rail placement to improve dairy cow welfare, but found that different tie-rail positions did not affect cow and stall cleanliness, bedding quantity, and lying time. However, all tie-rail placements resulted in neck injuries, indicating the need for further research on alternatives to metal tie-rail bars.

Summary: This study investigated the microRNA (miRNA) cargos of exosomes isolated from milk in relation to the healthy conditions of the mammary gland. Differential expression analysis identified differentially expressed miRNAs in the comparisons between healthy cows, cows at risk of mastitis, and cows with subclinical mastitis. The analysis of miRNA cargos in milk exosomes can be considered as a promising approach to study the complex molecular machinery set in motion in response to mastitis in dairy cows.

Summary: The cessation of lactation in dairy cattle during the dry-off period has attracted significant research attention in recent years. This period is critical for tissue remodeling of the mammary gland but is also a stressful event that involves changes in routine, diet, and metabolism. High milk production in late gestation poses challenges for the dry-off phase, and strategies to gradually reduce milk yield and promote mammary involution have been proposed to optimize this critical period.

Summary: Mastitis is a common disease in dairy cows, which leads to inflammation of mammary tissue, decreased secretion function of mammary gland cells, and affects milk production and quality, resulting in economic losses in the dairy cow industry. This study used 16S rDNA sequencing technology and lipidomics techniques to explore the relationship between microorganisms and lipids in dairy cows with mastitis. The results showed that microorganisms caused abnormal lipid metabolism through regulation of lipid metabolites, leading to a decrease in milk quality.

Summary: Physiological udder edema is a noninfectious metabolic disorder in dairy cattle that may be influenced by genetics, nutrition, oxidative stress, and physiological changes. It negatively impacts the productive life and milk production of dairy cows, as well as increases the risk of secondary diseases. Methods to manage udder edema include providing specific diets, selecting for lower milk production genetic lines, and ensuring an adequate intake of antioxidants in the diet.

Summary: The aim of this cross-sectional study was to investigate the occurrence of bacteremia in severe mastitis cases of dairy cows. Milk and corresponding blood samples of 77 cases of severe mastitis were bacteriologically examined. Bacteremia occurred in 15.5% of the cases, with the most frequent isolated bacteria being K. pneumoniae, E. coli, S. dysgalactiae, and S. uberis. High pathogen shedding and high humidity were associated with the occurrence of bacteremia in severe mastitis.

Summary: This case-cohort study investigated the behavior of sows and piglets during the periparturient period. The results showed changes in sow behavior before and after parturition, with reduced nesting behavior in PDS+ sows but no difference in other behaviors. This suggests that PDS may affect piglet-oriented behavior, but classical sickness behaviors are not reliable markers for PDS diagnosis.
