Summary: This study aimed to identify preoperative clinical, hematological, as well as intraoperative parameters associated with the prognosis of cows with right displacement of the abomasum (RDA) or abomasal volvulus (AV). The results showed that non-survivors had more severe dehydration, higher heart rate, lower sodium, and higher levels of L-lactate and phosphorus in their blood prior to surgery compared to survivors. During surgery, non-survivors had significantly more dilated and twisted abomasum than survivors. These findings can facilitate the early identification of animals with poor prognosis and the need for more intensive peri- and postoperative care.

Summary: This study used metagenomics, metatranscriptomics, and metabolomics to uncover ruminal microbial features associated with feed efficiency in dairy cows. The results showed that high-efficiency animals had more and stronger microbial interactions in the rumen, with Selenomonas and members of the Succinivibrionaceae family playing key roles in carbohydrate metabolism. Analysis of ruminal metabolites identified six carbohydrates-derived metabolites as potential markers to differentiate efficient and inefficient microbiomes.

Summary: This study investigated the postprandial plasma metabolome following consumption of different dairy matrices, and found that the structure and texture of the dairy matrix can affect the absorption of amino acids and metabolic products.

Summary: This survey investigated the use of antimicrobial prophylaxis for cesarean section (CS) and left displaced abomasum (LDA) correction in the cattle industry. It found that older veterinarians used more antimicrobials for CS than recent graduates, while antimicrobial prophylaxis in LDA surgeries varied significantly based on the correction methods used.

Summary: This study investigates the use of metabolomics and machine learning to detect lameness in dairy cattle. The findings demonstrate that these methods can predict lameness as early as before calving and before observable changes in gait, with high accuracy. These findings are significant for early prediction and prevention of lameness risk in dairy cows.

Summary: This study investigates dairy workers' attitudes towards euthanasia of dairy cattle and their association with demographic characteristics. The results show that some workers feel uncomfortable with euthanasia, while others feel confident and comfortable. White workers and caretakers with previous euthanasia experience are more likely to have positive attitudes towards euthanasia, while respondents who work on farms with 501-1000 cows are more likely to have negative attitudes towards euthanasia.

Summary: This study investigated gastrointestinal tissue damage in cattle with right displacement of the abomasum (RDA) and left displacement of the abomasum (LDA) using intestinal-related biomarkers. The results showed that L-FABP concentrations in the LDA group and TFF-3 concentrations in the RDA group were lower than in the control group, while the leptin concentration of the RDA group was higher. There were negative correlations between lactate, leptin, and IL-8 concentrations. Leptin was identified as the most reliable biomarker for discriminating between RDA and LDA cases.

Summary: This study evaluated the metabolic profiles of five biofluids in dairy cows using proton nuclear magnetic resonance imaging. Different metabolites were identified in each biofluid, with some unique to specific biofluids. The purpose was to verify the ability of metabolomics approaches to identify metabolites in the biofluids of dairy cows.

Summary: Rotational crossbreeding, while potentially more effective than pure breeding in improving dairy cattle systems, remains rare in France due to the prevailing sociotechnical regime centered on pure-breeding and high-specialization paradigms in herd management. Despite recognized benefits for farm sustainability, the lack of technical references and presence of various barriers hinder widespread adoption of dairy crossbreeding practices.

Summary: This study aimed to explore perspectives and attitudes about euthanasia in the Brazilian dairy cattle industry. The lack of nationally recognized euthanasia guidelines and effective euthanasia tools makes it challenging for veterinarians to carry out humane on-farm euthanasia. Additionally, logistical factors and the human-animal bond also contribute to the failure to perform euthanasia when necessary. Future research should focus on developing science-based standards and training programs to improve consistency in on-farm euthanasia in Brazilian dairy operations.

Summary: This study investigated the metabolic changes associated with natural MAP infection in dairy cattle using NMR spectroscopy and routine blood chemistry. The results showed altered metabolic pathways, including increased tyrosine metabolism and enhanced phenylalanine, tyrosine, and tryptophan biosynthesis in MAP-infected cattle. Increased synthesis and degradation of ketone bodies were observed in both infected and infectious cattle. The fusion of multiple data sources proved to be useful in exploring these metabolic pathway changes and potentially diagnosing negative animals within paratuberculosis-infected herds.

Summary: The objective of this study was to investigate the impact and slide of cows walking on different flooring surfaces commonly used in Ontario dairy farms. The results showed that the type of flooring surface significantly affected hoof impact and slide, indicating the need to consider these factors in future studies.

Summary: The study focused on developing a mechanistic model for dairy cows to analyze the yield gap in dairy production systems and evaluating the model performance. The newly adapted LiGAPS-Dairy model showed acceptable performance when applied to Holstein-Friesian cows under Dutch conditions, suggesting potential for further evaluation in other production systems, countries, and breeds for exploring options to increase resource use efficiency in dairy production.

Summary: Lameness in cattle is often underestimated on farms, but early detection can lead to improved outcomes. Conventional locomotion scoring systems can be subjective and inconsistent, but pairwise comparison scoring offers a more reliable alternative with finer granularity. In this study, pairwise scoring showed greater intra- and interobserver consistency compared to traditional absolute scoring methods, providing a more informative assessment of cattle gait.

Summary: Vaccination is the most effective way to prevent infectious diseases, and adjuvants are necessary to enhance the immune response. This study revealed the potential adjuvant effect of boric acid in vaccines, showing reduced inflammatory reactions and increased antibody levels. Further target animal studies are needed to confirm these findings.

Summary: The aim of this study was to determine the pharmacokinetic change of meloxicam in sheep after intravenous administration at different doses. The results showed that the duration of meloxicam in plasma, as well as the elimination half-life and area under the concentration-time curve, increased as the dose increased, while the total clearance decreased. Meloxicam exhibited non-linear pharmacokinetics in sheep, and when administered intravenously at a dose of 1 mg/kg or above, plasma concentrations became unpredictable.
