Summary: The study found that breed and transport/lairage conditions were the most important factors influencing different caspase activities, with the Rubia Gallega breed showing a completely different behavior compared to the Asturiana de los Valles and Retinta breeds. Additionally, it is postulated that the apoptosis cascade is initiated through the activation of caspase 9 under hypoxic or metabolic stress, followed by the activation of executioner caspases 3/7.

Summary: A new non-contact estrus detection method for tie-stalled cows was developed by combining the background subtraction technique and the thresholding method, achieving a high sensitivity of 90% in detecting estrus-associated activity increases. By utilizing front-view videos with an appropriate threshold, estrus detection with 90% sensitivity and 50% precision was demonstrated. This method shows promise as a non-contact estrus detection method for tie-stalled cows.

Summary: Early diagnosis of cattle diseases is important economically and clinically. This review compares different sampling devices, sample preparation techniques, instrumentation, and statistical analysis approaches for the diagnosis of common cattle diseases. The studies mainly focus on ketosis and bovine respiratory disease (BRD), but the results are not consistent and further investigation is needed to identify specific biomarkers for BRD. Defining useful VOC profiles, considering animal welfare, and practical application at the producer level are also challenges. Controlled clinical studies are required before breath analysis can be routinely performed on cattle.

Summary: Animal welfare is an integral part of livestock production and sustainability. Qualitative Behaviour Assessment (QBA) is a technique used to assess animal welfare, with behavior being a key component. Video-QBA (V-QBA) is a method that uses video footage for assessment, and studies have found broad agreement between V-QBA and live QBA results. However, caution should be taken when implementing V-QBA due to the lack of absolute agreement and lower scores obtained in some cases.

Summary: Dairy cows tend to stand as a response to heat stress, which negatively affects their productivity and welfare. This study focuses on the lying postures of cows as behavioral indicators of countermeasures. It is predicted that cows will decrease the time they lie with their heads turned back as an adaptive response to heat stress.

Summary: The aim of this study was to test the validity of 'avoidance distance at pasture' (ADP) as a measure of human-animal relationship (HAR) for grazing dairy cows. The results showed that ADP had high inter-observer reliability, but low stability over short-term and long-term time, and no significant relationship with ADF. Therefore, ADP cannot be entirely validated as a measure of HAR at this stage. Further studies are warranted to address factors that make ADP variable with time and to investigate the selectivity of this measure through a construct validity process.

Summary: In New Zealand, a study on unintentional child work-related fatal injuries revealed that majority of incidents involved vehicle crashes or being struck by moving objects on farms or public roads. Males, preschoolers, and those of Maori or European ethnicity were identified as high-risk groups. Work contributed significantly to unintentional fatal injuries in children, with most deaths being preventable through adult intervention and legislation. Increased focus on rural farm and transport settings could greatly reduce injury mortality rates among New Zealand children.

Summary: Immigrant workers, especially those in jobs like agriculture, face occupational health and safety concerns. This study found that the number of types of personal protective equipment and training positively predicted safety climate, which in turn negatively predicted occupational stress. Occupational stress was associated with negative outcomes like depression and anxiety, highlighting the importance of workplace safety for immigrant workers' health and well-being.

Summary: Mobile zoos involve transporting non-domesticated and domesticated species to various venues for educational, entertainment, or therapeutic purposes. Research conducted in 74 countries identified numerous concerns regarding animal welfare, public health and safety, and the accuracy of promotional materials. Mobile zoos remain largely unregulated, unmonitored, and uncontrolled, and there has been an apparent increase in their prevalence. Based on the precautionary principle, it is advised that the use of exotic species in mobile zoos be discontinued.

Summary: This study found that the transfer of antimicrobial resistance genes can result in the selection of resistance, even without the use of antimicrobials. A previously unreported combination of resistance genes in Escherichia coli was identified, including genes for antibiotics only used in dairy cattle under 20 months of age. The antibiotics resistant to these genes are considered critically important and highest priority for human medicine by the World Health Organization.

Summary: Among dairy workers in Bailey County, Texas, those at high risk for occupationally acquired TB were younger, primarily Guatemalan males with lower levels of formal education, more likely to be single with no children, and more likely to cohabitate with coworkers compared to those at medium/low risk. No significant associations were found between job categories and reported history of TB exposure. Future studies should focus on the feasibility of offering on-farm health services, such as TB screening, to prevent and control the disease among dairy workers.

Summary: The manureshed represents the cropland needed to safely assimilate manure nutrients from an animal feeding operation. This study reviews the challenges and opportunities for manureshed management in four major dairy-producing states, finding that manureshed requirements vary across regions and are constrained by the import of feed and soil phosphorus accumulation. Some regions rely on informal networks to relocate surplus manure nutrients off the farm, while others need to strengthen these networks for sustainable manureshed management.

Summary: Forage maize and sorghum can improve their quality by intercropping with annual legumes, leading to greater dry matter and light interception. The land equivalent ratio was higher in intercropping systems compared to sole crops. Maize produced more dry matter than brown midrib and brachytic dwarf sorghums, and both LAI and LI increased rapidly before stabilizing. Intercropping systems reached greater LAI and intercepted more light earlier than sole crops. RUE varied with season, crop, and year. Lablab was found to be superior to lima bean for intercropping with maize or sorghum for forage production.
