In Africa, Rift Valley Fever poses a substantial risk to animal health, and human cases occur after contact with infected animals or their tissues. RVF has re-emerged in Uganda after nearly five decades, with multiple outbreaks recorded since 2016. We investigated a unique RVF outbreak associated with an animal abortion storm of 30 events and human cases on a dairy farm in Mbarara District, Western Uganda, in February 2023. Genomic analysis was performed, comparing animal and human RVF viruses (RVFV) circulating in the region. A cluster of thirteen human RVF cases and nine PCR-positive animals could directly be linked with the abortion storm. Overall, during the year 2023, we confirmed 61 human RVFV cases across Uganda, 88.5% of which were reported to have had direct contact with livestock, and a high case fatality rate of 31%. We recommend implementing extensive health education programs in affected communities and using sustainable mosquito control strategies to limit transmission in livestock, coupled with initiating animal vaccination trials in Uganda.

Fascioliasis, a parasitic disease caused by liver flukes of the genus Fasciola, remains a significant threat to livestock productivity globally. Despite its economic and zoonotic importance, the knowledge levels of dairy farm personnel regarding this disease remain insufficiently explored in South Africa. This study assessed knowledge and awareness of bovine fasciolosis, including its etiology, risk factors, clinical signs, zoonotic implications, and control measures, among dairy farm personnel in the Eastern Cape Province. A structured questionnaire was randomly administered to 152 dairy farm workers. Descriptive statistics and Chi-square tests were used to examine associations between respondents’ demographic characteristics and their knowledge of fasciolosis. Most respondents were males (65.8%), aged 31–40 years (45.4%), with tertiary education (64%), over six years of experience (65%), and residing in inland regions (65.4%). A high proportion reported implementing pasture management practices such as irrigation (90.8%), pasture resting (69.8%), and rotation (94.7). Significant associations were found between geographic location and knowledge of Fasciola spp. as the causative agent, as well as awareness of swampy areas and water snails as key risk factors (p < 0.01). Educational level was significantly associated with awareness of the zoonotic potential of fasciolosis (p < 0.01), and regional location influenced knowledge on control practices (p < 0.01). These findings highlight persistent gaps in the understanding of bovine fasciolosis among dairy farm personnel, particularly in relation to causative agents, clinical signs, and zoonotic risk. Strengthening extension services, enhancing community awareness, and implementing targeted training programs are essential to address these knowledge gaps and improve disease control strategies in the Eastern Cape Province.

Consumers expect ruminants to graze outdoors and flocks to be of a reasonable size. Dairy goats can be kept outdoors (natural) or indoors. There are few pasture-grazed-system goat farms. The farms we studied in the centre-west of France were either organic or conventional, and all used pastures and tended to meet consumer demand for naturalness. We obtained information through semi-directed interviews. Dairy goats are susceptible to gastrointestinal infections when using pastures and this was one of the main health problems mentioned by organic farmers. There are a very limited number of medicines available for lactating dairy goats and farmers can use complementary and alternative veterinary medicine (CAVM), where they are completely autonomous in their choice. The use of CAVM has also been driven by organic labels and protected designation of origin (PDO) regulations for goat cheese. Homeopathy, phytotherapy, and aromatherapy were used for various health problems on almost all the farms surveyed. Herd size and farm area were negatively associated with the complex use of CAVM, possibly due to the workload on larger farms. Some CAVMs were used more in relation to the management of farms: aromatherapy in organic farms and homeopathy in cheese-making farms. The farmers with higher levels of education were more likely to employ phytotherapy. The farmers were autonomous in the choice of CAVM and did not rely on the advice of veterinarians. Full article

Biosecurity is essential in livestock farming to prevent the spread of diseases, ensure animal welfare, and maintain farm sustainability. In Portugal, small ruminant farms are predominantly extensive and small-scale, and most of them are familiar, especially in the northern and inland regions. Thus, biosecurity implementation on these farms is low due to factors such as an aging livestock farmer population, poor training, limited veterinary support, and economic constraints. This study, the first to assess biosecurity on Portuguese small ruminant farms, evaluated compliance levels and the influence of sociodemographic factors. A cross-sectional study was conducted between July 2023 and April 2024, through structured interviews with 276 farmers. A 32-question checklist covering nine biosecurity categories was used to assess compliance. The results revealed poor implementation of key biosecurity measures, particularly cleaning and disinfection, quarantine protocols, and visitor control. Inadequate premises infrastructure, including the absence of quarantine areas, isolation facilities for sick animals, and farrowing rooms, further hampered disease prevention. Compliance was influenced by farmers’ age, education level, herd size, and production. Larger farms, particularly dairy farms, demonstrated better biosecurity practices, likely due to better management and infrastructure. This study highlights the challenges of implementing biosecurity measures on small-scale, extensive farms and argues that standardized plans are ineffective. Instead, region- and farm-specific strategies are needed, considering the socioeconomic realities of farmers. Improving farmers’ education and access to veterinary services is crucial. Furthermore, public policies should provide financial incentives and educational programs to improve biosecurity without compromising farm viability. Strengthening biosecurity on small ruminant farms is vital to protecting animal and public health and ensuring the long-term sustainability of rural communities in Portugal. Full article

Transitioning to agroecology on dairy and beef farms is touted as a sustainable response to environmental externalities. The current study conducted narrative interviews with farmers who transitioned towards agroecological food production by implementing pro-environmental diversification measures in the Republic of Ireland, the United Kingdom and France. The study aimed to determine farmers’ experiences of agroecology and used a thematic approach for the analysis. Results indicate that the motivations, values and principles of farmers transitioning to agroecology are closely aligned with the ideology of the new/peasantry. Farmers’ decisions were primarily influenced by ecological principles and a sense of responsibility towards environmental protection, with particular biographical events central to the transition to an alternative food production system based on agroecology. Other explanatory factors related to farmers’ desires to increase the autonomy and profitability of the farm, and their conscious efforts to eliminate dependence on external inputs. Farmers who entered agriculture with no family background in farming had acquired skillsets which provided them with specific advantages in advancing towards agroecological goals. This paper provides insights relevant to policymakers, extension and education providers on how to practically support agroecological transition. Full article

Dystocia, or difficult labor, is a common complication during parturition in cattle that poses substantial risks to both dam and fetus. When the incidence is high on a farm level, it is a significant economic burden for dairy and beef enterprises. This review paper presents a comprehensive roadmap strategy to enhance decision-making in the management of dystocia in cows. The strategy encompasses early recognition and assessment, utilization of advanced diagnostic tools, and a range of medical and surgical interventions tailored to specific maternal and fetal causes of dystocia. The roadmap also integrates preventive measures to reduce the incidence of dystocia through genetic selection and optimized nutrition. By addressing the key challenges in dystocia management, such as resource constraints, timely intervention, and the need for continuous education, this strategy aims to improve health outcomes for cows and calves and reduce economic losses. Implementing this structured approach can facilitate better preparedness, efficient resource utilization, and improved overall livestock management, thereby promoting the sustainability and productivity of the cattle industry and addressing animal welfare aspects.

This study investigates public perceptions in Texas regarding two common calf disbudding methods used in dairy farming: caustic paste and hot iron. With growing consumer interest in humane animal treatment, understanding the preferences for these methods provides insights into public expectations of welfare in agricultural practices. The study utilized an online survey distributed to Texas residents via the Centiment research platform, assessing preferences, demographic influences, and the impact of scientific information on perceptions. Results, from 511 participants, indicated a stronger preference for caustic paste, especially among women and participants with higher education levels, while hot iron was favored more by men. Dietary habits, such as seafood and cheese consumption, also influenced preferences, with higher consumption linked to a preference for caustic paste. Viewing images of the disbudding techniques affected the willingness to purchase, consume, and serve beef, with hot iron prompting a greater negative response. The findings suggest that public knowledge and awareness can significantly impact perceptions surrounding animal welfare practices and that education could play a critical role in aligning consumer preferences with humane agricultural practices. These insights are valuable for the dairy industry, informing practices that are more aligned with public expectations and supporting the promotion of welfare-oriented disbudding methods.

Standards for data generation and collection are important for integration and for achieving data-driven actionable insights in dairy farming. Data integration and analysis are critical for advancing the dairy industry, enabling better decision-making, and improving operational efficiencies. This commentary paper discusses the challenges of and proposes pathways for standardizing data generation and collection based on insights from a multidisciplinary group of stakeholders. Drawing from a series of meetings of industry experts, academics, and farmers organized under the Dairy Brain Project’s Coordinated Innovation Network (CIN), we explore the benefits of creating uniform data generation and collection protocols to ensure compatibility and reliability across different data sources. Key insights include the importance of defining standardization at both farm and industry levels, the role of education and incentives, and the potential for using existing frameworks such as the International Committee for Animal Recording. Additionally, we highlight industry-specific case studies, including successful examples from Brazil such as GERAR, which focuses on reproductive performance data, and Labor Rural, which integrates data from multiple farms to provide valuable insights to farmers and milk processors. The paper concludes with recommendations for implementing these protocols and highlights the need to foster collaboration among stakeholders for the successful implementation and adoption of standardized data generation and collection protocols in the dairy industry.

For decades, bovine mastitis and milk quality have been a focus area for research, agricultural extension, and dairy processors worldwide, yet employee management as a factor in udder health management has received limited attention. This is mainly because the focus has previously been on more classical areas covered by the National Mastitis Council Mastitis Control Program (NMC 10-point plan) in English-speaking countries. Therefore, we wanted more background information on employee management on dairy farms, to identify the human factor of udder health management. The method of investigating employee management and the impact of employee management on udder health was conducting a study of 88 Danish dairy farms with hired employees and parlor or rotary milking systems. An interview-based questionnaire on individual dairy farmers’ human resource management was developed based on the current literature and multiple discussions among the authors. The results we found through analyzing associations between the dependent variable BTSCC and employee management, using a regression model, was that providing a generic SOP was associated with a 21,600 cells/mL increase in BTSCC, with estimates in the range (507; 42,674 cells/mL). We also analyzed, applying a Poisson model, that there was a 0.16% reduction in new infection risk if the training was based on a herd-specific SOP and educated employees. In contrast, we identified a 0.15% increase in new infection risk in herds where SOPs were available but not incorporated, both modest but significant results. In conclusion, farms with educated employees and trained by an SOP achieve the lowest new infection risk, but education has no impact on BTSCC. Full article

The dairy industry is facing criticism for its role in exacerbating global GHG emissions, as climate change becomes an increasingly pressing issue. These emissions mostly originate from methane (CH₄), nitrous oxide (N₂O), and carbon dioxide (CO₂). An optimal strategy involves the creation of an economical monitoring device to evaluate methane emissions from dairy animals. Livestock production systems encounter difficulties because of escalating food demand and environmental concerns. Enhancing animal productivity via nutrition, feeding management, reproduction, or genetics can result in a decrease in CH₄ emissions per unit of meat or milk. This CH₄ unit approach allows for a more accurate comparison of emissions across different animal production systems, considering variations in productivity. Expressing methane emissions per unit allows for easier comparison between different sources of emissions. Expressing emissions per unit (e.g., per cow) highlights the relative impact of these sources on the environment. By quantifying emissions on a per unit basis, it becomes easier to identify high-emission sources and target mitigation efforts accordingly. Many environmental policies and regulations focus on reducing emissions per unit of activity or output. By focusing on emissions per unit, policymakers and producers can work together to implement practices that lower emissions without sacrificing productivity. Expressing methane emissions in this way aligns with policy goals aimed at curbing overall greenhouse gas emissions. While it is true that total emissions affect the atmosphere globally, breaking down emissions per unit helps to understand the specific contributions of different activities and sectors to overall greenhouse gas emissions. Tackling cattle health issues can increase productivity, reduce GHG emissions, and improve animal welfare. Addressing livestock health issues can also provide favourable impacts on human health by reducing the prevalence of infectious illnesses in livestock, thereby mitigating the likelihood of zoonotic infections transmitting to humans. The progress in animal health offers the potential for a future in which the likelihood of animal diseases is reduced because of improved immunity, more effective preventative techniques, earlier identification, and innovative treatments. The primary objective of veterinary medicine is to eradicate clinical infectious diseases in small groups of animals. However, as the animal population grows, the emphasis shifts towards proactive treatment to tackle subclinical diseases and enhance production. Proactive treatment encompasses the consistent monitoring and implementation of preventive measures, such as vaccination and adherence to appropriate nutrition. Through the implementation of these measures, the livestock industry may enhance both animal well-being and mitigate the release of methane and nitrous oxide, thereby fostering environmental sustainability. In addition, advocating for sustainable farming methods and providing farmers with education on the significance of mitigating GHG emissions can bolster the industry’s endeavours to tackle climate change and infectious illnesses. This will result in a more robust and environmentally sustainable agriculture industry. This review seeks to conduct a thorough examination of the correlation between the health condition of cattle, the composition of milk produced, and the emissions of methane gas. It aims to identify areas where research is lacking and to provide guidance for future scientific investigations, policy making, and industry practices. The goal is to address the difficulties associated with methane emissions in the cattle industry. The primary global health challenge is to identify the causative relationship between climate change and infectious illnesses. Reducing CH₄ and N₂O emissions from digestive fermentation and animal manure can be achieved by improving animal well-being and limiting disease and mortality. Full article

The adoption of effective coping strategies is crucial for successful adaptation to the impacts of climate change in the dairy sector. However, little attention has been paid to understanding the perceived constraints and motivations toward such strategies. A survey was conducted among 104 dairy farmers from three semi-arid regions of South India. The aim of the survey was to explore the dairy farmers’ perception of climate risk, how it impacts their dairy farming system, the coping strategies they employ, and the barriers they face when implementing these strategies. The survey also investigated the factors that facilitate the adoption of adaptation measures. The results indicate dairy farmers in the region perceive drought, pests and diseases, and high temperatures as the major risks associated with climate change, which has resulted in decreased dairy income, animal health problems, reduced fertility, and food intake problems for their cattle. In response to climate variability, dairy farmers have adopted various coping strategies. The most important strategies include buying livestock insurance, keeping low debt obligations, and growing drought-tolerant grass varieties. However, most farmers face significant constraints in adopting these and other strategies including a lack of climate forecast data, the high cost of adaptation activities, and weak institutional support. On the other hand, the key enabling factors that support the adoption of these strategies include milk production security, suitable feed growing conditions, and family interest. Most importantly, the study found that certain factors such as age, education, number of earning family members, annual milk production, monthly cattle expenses, and landholdings significantly influenced dairy farmers’ strategies for adapting to climate change. The study recommends that providing timely climate forecasts, implementing improved policies such as vaccination and cattle health services, and establishing strong institutional support systems can help dairy farmers become more resilient to climate change and protect their livelihoods.

Selective dry-cow therapy (SDCT) became mandatory in Italy on 28 January 2022. During 2020, a group of farms involved in a milk quality program began a pilot experiment with SDCT in order to understand its challenges and to identify areas for procedural improvements. The aim of this study was to describe the challenges and results of the SDCT in early adopters’ herds with a special focus on treatment compliance. Retrospective data from 1911 cows from 11 dairy herds were evaluated. Somatic cell counts, clinical mastitis (CM) history, and the California Mastitis Test (CMT) were used as criteria for SDCT. Based on the dairy herd improvement test results and CM history, 48% of all cows should have received antibiotic treatments and internal teat sealants. Adding the CMT at dry-off increased the percentage of antibiotic-treated cows to 62%, with relevant variation among farms. Concerning treatment compliance, 21% of the cows were “non-compliant”, suggesting the importance of monitoring treatment compliance. In conclusion, even if commonly used selection criteria for antibiotic treatments were used, the need for more education and in-depth monitoring of the SDCT adoption process was clearly identified. Close collaboration and agreement between veterinarians and farmers are key for SDCT adoption success. Full article

Climate change mainly affects the production and consumption systems associated with food, livelihoods, production (e.g., reduced milk production), water, and land use. The role of local knowledge is recognized as important for decision-making under changing circumstances. This study was conducted in the northern part of the Ecuadorian Andes using a sample of 170 dairy-cattle-farming households. The objectives were to: (i) characterize the rural livelihoods of dairy cattle farmers; (ii) evaluate access to climate information and perceptions of climate change; and (iii) determine the relationship between livelihoods and perceptions of climate change. Significant differences were identified between the groups evaluated in relation to the dairy farmers’ livelihoods. In addition, 85.29% of the respondents indicated that climate information is important, but 67.83% did not trust the sources of information. It was found that there is a significant relationship between the level of education and age with the variables of climate change perceptions. This combined knowledge will allow people to promote agri-environmental and educational policies to achieve climate literacy at a rural level. Full article

The present study was carried out with the objective of understanding the stated interest of agricultural students in entrepreneurship and to provide an accurate research report for decision-makers, for developing entrepreneurship in India. In the present investigation, a two-stage sampling procedure was employed. In the first stage, cluster sampling was used to select the state agricultural universities (SAUs) in India. In the second stage, simple random sampling was performed to select student respondents from each SAU. Data were collected from 1797 agricultural students (second stage units) from 17 SAUs out of 74 (first stage units) studying a bachelor’s/master’s degree program and analyzed to infer outcomes related to entrepreneurship. Variables such as basic information, job interest, motivational factors, hurdles to becoming an entrepreneur, awareness about government schemes, and essential hard and soft skills were measured. Data were analyzed using frequencies, chi-square test (X²), rank-based quotient (RBQ), and binary logistic regression (BLR) analyses. The survey results revealed that “entrepreneurship” was given a lower preference by the majority; as a result, there was less motivation for students from family members. However, about 78% of students showed interest in becoming an entrepreneur. Significant areas of entrepreneurial interest for the observed students included, in order are digital agriculture < input production < marketing < farming < advisory services < dairying < financial services < poultry < developing eLearning material for farmers < and other jobs. This study demonstrates the need for Career Development Centers (CDCs), government support, and awareness and incentives regarding entrepreneurship through effective policy interventions, to protect entrepreneurs from the potential risk of business losses. This research outcome substantially contributes to the Sustainable Development Goal (SDG-4, quality education), through the soft skill development of the students, resulting in innovative agri-entrepreneurs. The present research suggested some policy implications to promote entrepreneurship more widely, which may also help other developing countries to frame potential regulations for agricultural education and entrepreneurial activities.

Bovine brucellosis is a bacterial zoonoses caused by Brucella abortus. We conducted a cross-sectional study to determine brucellosis seroprevalence and risk factors among smallholder dairy cattle across six regions in Tanzania. We sampled 2048 dairy cattle on 1374 farms between July 2019 and October 2020. Sera were tested for the presence of anti-Brucella antibodies using a competitive enzyme-linked immunosorbent assay. Seroprevalence was calculated at different administrative scales, and spatial tests were used to detect disease hotspots. A generalized mixed-effects regression model was built to explore the relationships among Brucella serostatus, animals, and farm management factors. Seroprevalence was 2.39% (49/2048 cattle, 95% CI 1.7–3.1) across the study area and the Njombe Region represented the highest percentage with 15.5% (95% CI 11.0–22.0). Moreover, hotspots were detected in the Njombe and Kilimanjaro Regions. Mixed-effects models showed that having goats (OR 3.02, 95% C 1.22–7.46) and abortion history (OR 4.91, 95% CI 1.43–16.9) were significant risk factors for brucellosis. Education of dairy farmers regarding the clinical signs, transmission routes, and control measures for brucellosis is advised. A One Health approach is required to study the role of small ruminants in cattle brucellosis and the status of brucellosis in dairy farmers in the Njombe and Kilimanjaro Regions. Full article
