Divergence of nutrients, salt accumulation, bacterial community structure and diversity in soil after 8years of flood irrigation with surface water and groundwater.

Irrigation with saline groundwater has become necessary to overcome freshwater scarcity in the agricultural industry in arid areas. However, the effects of long-term saline groundwater irrigation on soil salinity and bacterial diversity have rarely been examined. In this study, a Lycium ruthenicum field was divided into two parts and subjected to flooding irrigation with saline groundwater (pH 7.81, total salinity 0.95g L-1) and surface water (pH 7.76, total salinity 0.36g L-1) for 8years. After 8years of irrigation, the soil salinity and salt ion content (i.e., Na+, Mg2+, K+, Ca2+, Cl- and CO32-) in the groundwater irrigation group were significantly greater than those in the surface water irrigation group (p < 0.001), with notable accumulation in the topsoil (0-5cm) (p < 0.01). The bacterial community structure differed between the surface water and groundwater irrigation groups. Salt-tolerant bacterial groups (e.g., Balneolaceae and Halomonadaceae) and species (e.g., the marine bacterium JK1007, the bacterium YC-LK-LKJ35, and Methylohalomonas lacus) dominated in the groundwater irrigation environment. Additionally, bacterial communities were associated primarily with soil salt ions (RV = 0.66, p < 0.001). The characteristic bacterial taxa in long-term groundwater irrigation soils were salt-tolerant species (e.g., the marine bacterium JK1007, the bacterium YC-LK-LKJ35, and Methylohalomonas lacus). These findings suggest that salinity is the key factor driving differences in bacterial community structure between long-term groundwater and surface water irrigation. The long-term use of surface water and groundwater for irrigation has different impacts on soil environments, with groundwater irrigation having a more pronounced negative effect. Highlights. The long-term effects of this practice on soil salt accumulation and bacterial diversity were examined. This study provides potential applications for sustainable land management in similar ecological contexts. Groundwater irrigation is characterized by saline-tolerant keystone species. Salinity filtering was used to determine the pattern of bacterial community construction.

Towards an Emplaced Vocabulary of Motive: Senses of Place and Land Sale Decision‐Making in the Northern Great Plains*

AbstractOne of the most remote regions in the contiguous United States, the Upper Missouri River Breaks in the Northern Great Plains of Montana is both “cattle country” and “pristine prairie”: an identity that brings repeated tension over land use. Over the last twenty years, a conservation organization with a mission to rewild the region has purchased thousands of acres of ranchland from willing sellers despite widespread agricultural community resistance. In this study, I interview those who chose to sell and those who chose to stay, and I ask how landowners justify their decisions to sell, or not sell, their land. By using what C. Wright Mills calls “vocabularies of motive,” I investigate two central questions. The first asks why a landowner would sell land against what social norms would dictate to be “right.” The second asks why a landowner would not sell land, given the perceived inevitable eventual loss of a regional agricultural livelihood. I suggest one way to understand these questions is by considering how senses of place shape what decision‐makers believe to be the most justifiable course of action. Extending the vocabulary of motive framework to include senses of place better informs the understanding of land sale decision‐making. Though deeply contextual, the themes running through this case (i.e., ongoing existential threats to the agricultural industry, booms in the buying power of private philanthropists, and decision making in socially and politically contentious spaces) are relevant to a broader understanding of shifts within agricultural communities and the ongoing perceived “battle” between production and conservation.

Simultaneous One-Step Preparation of β/κ-Carrapentaose and 3,6-Anhydro-D-galactose by Cascading κ-Carrageenase and an Exo-α-3,6-Anhydro-D-galactosidase.

Carrageenan oligosaccharides have shown promising bioavailability and possess a variety of physiological activities, making them highly suitable for use in the food, pharmaceutical, and agricultural industries. The preferred method for producing carrageenan oligosaccharides is using various carrageenolytic enzymes, as it offers mild reaction conditions, high efficiency, and product specificity. However, there is still a lack of specific applications for using these enzymes to prepare odd-numbered carrageenan-oligosaccharides (OCOSs). Our previous research identified a more convenient route for simultaneously preparing OCOSs and 3,6-anhydro-D-galactose (D-AHG) using only two types of carrageenolytic enzymes: κ-carrageenase and exo-α-3,6-anhydro-D-galactosidase (D-ADAGase). In this study, we utilized a CipA-based self-assembly system to cascade κ-carrageenase CaKC16A and D-ADAGase ZuGH129A for one-step preparation of β/κ-carrapentaose, G-(DA-G4S)2, and D-AHG from degrading β/κ-carrageenan. This self-assembled enzyme, namely CipA-CaKC16A-ZuGH129A, can be easily obtained through a simple centrifugation process. The final optimized enzymatic process produced 0.74 g/L G-(DA-G4S)2 and 0.13 g/L D-AHG. This cascade system of different types of carrageenolytic enzymes has the potential to achieve the preparation of various types of carrageenan oligosaccharides.

OIL PRICES-GROWTH NEXUS IN ALGERIA USING THE MEDAS MODEL

Objective: This Article aims to investigate the impact of oil price fluctuations on economic growth in Algeria using the Mixed Data Sampling (MIDAS) model during the period 1990-2022 Theoretical Framework: The theoretical aspect addressed the different time-frequency models by defining the Midas models and addressing the weighting functions used in estimating these models. Method: Estimating the relationship between a high-frequency variable (oil price) and a low-frequency variable (economic growth rate GDP) using the MIDAS model using Almon's PDL Weighting Function. Results and Discussion: The results of the study concluded economic growth in Algeria is directly affected by oil prices, The study also found that MIDAS models have a great predictive ability, allowing researchers to utilize all available information for high-frequency variables, instead of using annual average values that lose a lot of information. avoid converting low-frequency variables to match high-frequency variables, reducing econometric issues in model diagnostics. Research Implications: Research Implications: It is suggested that rentier countries such as Algeria work to diversify their economy away from oil, and follow up the process of economic diversification and accelerate it during periods of high fuel prices by working to develop non-strategic sectors as agriculture, tourism and manufacturing industries. Originality/Value: These results are expected to benefit policymakers in government, by urging them to invest in renewable energies as a crucial strategy for achieving sustainable development and a key factor in mitigating oil price shocks, particularly during recent recurring global crises. Future research directions include exploring existing gaps and promoting standardized studies.

Process safety in bioenergy with carbon capture and storage systems (BECCS)

AbstractIn response to the climate crisis, the United States has embarked on an ambitious program to achieve 100% carbon‐free electricity generation by 2035 and net‐zero greenhouse gas emissions by 2050. The implementation of bioenergy with carbon capture and storage (BECCS) systems is an essential component of that strategy. BECCS is broadly defined as the utilization of biomass energy (from the processing of solids, liquids, or vapors) with the capture of carbon dioxide and subsequent permanent storage in a deep geological formation. There are numerous potential technologies and flowsheets for implementing BECCS, and the supply chains rely upon support from the agricultural, forestry, and solid waste industries. Inherent in BECCS systems are the hazards associated with combustible dusts, spontaneous ignition and smoldering of combustible solids, flammable liquids, flammable vapors and gases, toxic gases, and more. For BECCS to be deployed commercially across the United States, it is imperative that process safety risks are controlled. A risk‐based process safety (RBPS) program can help manage the risks of a BECCS facility and minimize process safety incidents. In this paper, we present two representative bioenergy technologies as mini‐case studies to illustrate the range of process hazards encountered. Process safety strategies required by regulation are briefly reviewed and potential gaps are identified. We then demonstrate how RBPS can be implemented in a practical and effective manner to fill the gaps.

Public Preparedness for Agricultural Investment and its Contribution to Sustainable Economic Growth in Nigeria

Purpose: The study investigated public preparedness for agricultural investment and its contribution to and economic growth in Nigeria. The study was guided by the following objectives; to assess the level of individuals' awareness on the current condition of the agriculture industry in Nigeria, public's perspective of the substantial influence of agricultural on Nigeria's overall economic growth, the preparedness of citizens to invest in the agriculture sector for the enhancement of Nigeria's economic growth and delineate the agriculture sector's contribution to GDP. Theoretical Framework: The study was anchored on Lewis (1979) theory of impacting economic growth. Method: The study utilized a descriptive research approach involving 133 respondents across the 36 states, including the federal capital territory, whose major vocation is food production. The samples were selected by a convenience sampling method, considering the respondent geographic closeness and included only those present throughout the survey. Closed-ended questionnaire was utilized as a data-collecting instrument to assess the variables under study; the data on the contribution of agricultural practices to GDP was access from Nigeria Bureau of Statistics (2022-2023). To ensure content validity, the survey instrument was validated utilizing the Lawshe's template. A threshold of 0.99 was noted, signifying that the questionnaire was both representative and comprehensible. The Cronbach alpha technique yielded a reliability coefficient of 0.83, affirming the instrument's homogeneity. The data was analyzed using frequency counts (f) and percentages (%) while the results was presented in graphs. Findings: The survey revealed that most respondents are aware of the current state of agriculture in Nigeria. The heightened awareness has impacted public perception of agriculture's significant role in national economic growth, as the majority of respondents acknowledged that agriculture not only provides food for the populace but also improves farmers' living standards by reducing poverty and hunger, thus promoting economic development. They are willing to invest in agriculture despite a decline in production and a reduced contribution to the national GDP. Conclusion: Although the agricultural sector's contribution to GDP has diminished, individuals are inclined to invest in agriculture therefore, enhanced engagement in agriculture, along with Nigeria's extensive arable land and various people and material resources, and the implementation of sustainable agricultural innovations, will result in significant economic growth.

Tensile Force Limits of the Sheep Spine: Comparison to Forces Required to Extricate Grain Entrapped Victims

ABSTRACT Objectives Grain storage facility entrapments continue to be of concern in the agricultural industry, with nearly 1,500 documented incidents recorded over the last 45 years. Previous research studies have shown that attempting to extricate a full-size pulling test dummy from a grain mass requires a substantial amount of tensile or pull force – e.g. up to 1.32 kN if “buried” at waist depth, 2.77 kN at chest depth, and 4.01 kN at head depth. There is, however, a paucity of studies on the amount of distraction the human lumbar spine region can endure. The objective of this research study was to test the maximum tensile force that could be exerted on a sheep’s spine (comparable to the human spine) before the intervertebral discs and surrounding ligament would show signs of failure. Methods Eight lumbar-region sheep spine segments were axially distracted using an MTS Criterion tensile testing machine, and the maximum forces were recorded. Results The average maximum force that the spinal discs and ligament withstood before showing signs of failure was 2.14 kN (standard deviation of 0.31 kN). This is comparable to the force required to extricate an individual entrapped in a grain mass at chest depth. Conclusion The authors recommend that grain entrapment victims should not be forcefully pulled out if buried to waist level or above due to two primary reasons: (1) the large variation in failure load observed in our experiment with sheep spines and (2) the lack of knowledge regarding the victim’s pre-existing medical condition. The extractive forces required to remove a victim of entrapment in grain overlaps with the force needed to cause potential damage to the sheep spine, as the 1.7–3.0 kN range is comparable to the 1.65–2.48 kN force range that causes axial failure in the spine.

Evaluation of Capital Utilization Efficiency in Agricultural Listed Firms Based on a Three-Stage Data Envelopment Analysis

Rural revitalization is intricately tied to national prosperity, with listed companies in agriculture, forestry, animal husbandry, and fisheries playing pivotal roles in driving this transformative agenda. However, these sectors face critical challenges, notably resource constraints and environmental pressures, which underscore the necessity of evaluating capital utilization efficiency. This study employs a combined three-stage DEA model and Malmquist index to analyze capital utilization efficiency across 85 listed companies within China’s agriculture, forestry, animal husbandry, and fishery industries over the period 2018–2022. The primary objectives are to quantify capital utilization efficiency, identify pathways for industry optimization, advance ecological agricultural sustainability, and offer valuable insights to investors and policymakers. Key findings include: (1) When grouped by sub-sector and adjusted to account for external environmental factors and random disturbances, the initial comprehensive capital utilization efficiency in agricultural companies was found to be significantly overestimated. Subsequent third-stage adjustments revealed decreases in average comprehensive efficiency, technical efficiency, and scale efficiency by 29.79%, 3.03%, and 27.37%, respectively, largely driven by a marked decline in scale efficiency, ultimately diminishing overall efficiency. (2) The capital utilization efficiency in agricultural trading firms remains suboptimal, with scale efficiency posing a critical limitation. High dependency on government subsidies and excess specialized personnel further constrain efficiency improvements. (3) Dynamic analysis using the DEA-Malmquist model indicates low total factor productivity in the agricultural sub-sector, primarily due to inefficiencies in capital management and suboptimal scale allocation. These findings underscore the need for targeted strategies to enhance resource allocation and management, bolster talent development and financial management frameworks, and drive technological research and development, innovation, and efficient capital allocation across the agriculture, forestry, animal husbandry, and fishery sectors.

The Effect of Saccharomyces cerevisiae Fermentation Product Supplementation on Pro-Inflammatory Cytokines in Holstein Friesian Cattle Experimentally Inoculated with Digital Dermatitis

Digital dermatitis (DD) poses a major animal welfare concern for the dairy industry, with even broader economic implications for the agricultural industry worldwide. The postbiotic, a Saccharomyces cerevisiae fermentation product (SCFP), has had a positive influence on the innate immune system of cattle, which makes it a potential candidate as a feed supplement as part of a prevention strategy for DD. This study investigated the effect of a commercial SCFP feed supplement compared to a control feed supplement on the production of pro-inflammatory cytokines (IL-1β and IL-6) by peripheral blood mononuclear cells (PBMCs) in Holstein Friesian steers experimentally infected with DD. The results showed that SCFP supplementation was associated with an overall reduced IL-1β production (p = 0.005), particularly prior to experimental inoculation with a DD lesion homogenate. However, the results of the analysis suggest that the innate immune system in the SCFP group became prepared to respond more rapidly to DD infection post-inoculation. During active (M2), chronic (M4), and focal flare-ups (M4.1) of DD, SCFP supplementation resulted in a more rapid secretion of IL-1β (M2: p = 0.038; M4/M4/1: p = 0.034). A more rapid response to DD infection for IL-6 was only found for chronic (M4) and focal flare-ups (M4.1) of DD (p = 0.006). These findings emphasize the difference in cytokine response between various stages of DD in the SCFP group compared to the control, highlighting implications for DD prevention and treatment.

The Construction of a Socialized Service Platform and System for “Internet + Agriculture” in China

The mismatch between supply and demand and inefficient supply in China’s agricultural product market is quite severe, making agricultural supply-side structural reform an important topic and task for rural economic work in China. The successful implementation of agricultural supply-side reform requires a comprehensive agricultural social service platform and system to support it. However, the current agricultural social service platform system in China faces issues such as a lack of coordination among service entities and poor information communication, making it difficult to meet the demands of supply-side reform. To address this issue, under the new circumstances of supply-side reform, this paper proposes the idea of reorganizing the agricultural social service platform and system through industrial chain collaboration theory, and applying “internet +” for technological reengineering of the agricultural social service platform system. Based on this, a new agricultural social service platform system architecture is constructed, which includes service entities, service platforms, service content, and operational models. The research findings provide guidance for agricultural product producers, distributors, sellers, and related service entities along the agricultural industry chain on how to use “internet +” for collaborative decision-making. This approach is beneficial for addressing the supply-demand imbalance and low resource allocation efficiency in China’s agricultural product market, thereby advancing the structural reform of China’s agricultural supply side.

The Possibility of Environmentally Sustainable Yield and Quality Management of Spring Wheat (Triticum aestivum L.) of the Cornetto Variety When Using Sapropel Extract

Sustainable development is one of the main directions of modern agriculture. First of all, sustainability in the agricultural sector can be achieved through the possible abandonment of traditional mineral fertilizers. Many decades of using these fertilizers have led to the degradation of arable soils and to soil and environmental pollution. As a result, this causes reductions in yields and the environmental quality of agricultural products and affects the health of the population. An alternative to traditional mineral fertilizers may be the use of innovative organomineral fertilizers obtained from local resources. These include manure, humus, compost, sediments, etc. In recent years, fertilizers obtained from the sapropels of the bottom sediments of lakes have become widespread. Their distinctive feature is the environmental friendliness and completeness of the content of chemical elements and substances necessary for the development and growth of plants. In addition, the methods of obtaining and applying these fertilizers allow us to talk about their effectiveness in use. The range of applications of these fertilizers is diverse, from use in the form of a dry extract applied directly to the soil to the use of liquid suspensions used at various stages of processing and from pre-sowing seed treatment to watering and spraying plants at different periods of vegetation. Moreover, an important aspect is the research work on the variational use of sapropel fertilizers on different crops, with different methods of production and concentrations and at different stages of processing. This publication contains the results of a study of the effect of the obtained innovative sapropel fertilizer on productivity, wheat grain quality, and economic efficiency (Triticum aestivum L.). To identify the optimal concentration of sapropel extract, laboratory studies were carried out to determine the germination energy and germination of wheat seeds of different varieties when they were soaked in various concentrations: 0.4, 0.8, 1.2, 1.6, and 2.0 g/L. The best indicators of germination energy and germination of wheat seeds during treatment with the extract were obtained at a concentration of 1.2 g/L. The research was conducted at an accredited variety testing laboratory. A field experiment was conducted in the fields of the agrobiological station of North Kazakhstan University named after Manash Kozybayev. The treatment of the seeds was carried out by soaking them in sapropel extract to evenly distribute the substance. The scheme of the field experiment included the option of using foliar treatment with a solution of sapropel extract at the tillering stage. As a result of the application of the obtained extract in the field, environmental and socio-economic efficiency was noted. The conducted field studies note its positive effect and effectiveness on the morphological, qualitative, and quantitative indicators of the wheat harvest. In the areas where wheat seeds were pretreated, as well as where foliar treatment with the resulting sapropel suspension was carried out, the best yield indicators were revealed. In these variants of the experiment with pre-sowing and pre-sowing and foliar treatment with the sapropel extract solution, the yield was 3.63 and 3.81 tons per hectare, respectively. The introduction of sapropel extract at the stage of seed treatment before sowing, as well as foliar processing of wheat at the tillering stage, will increase the efficiency and profitability of the agricultural industry and obtain a synergistic effect in the form of socio-economic efficiency and environmental safety of production. In our opinion, this will contribute to the development of sustainable agriculture and the production of environmental products.

Techno-Economic Feasibility: Planning an On-Grid Solar Power System for Shrimp Pond Aeration

The rapid growth of the Indonesian shrimp farming industry is accompanied by high production costs, primarily driven by the reliance on fossil fuel-based energy sources that can destabilize the ecosystem. This study investigates the technical, economic, and environmental feasibility of using three energy sources, including photovoltaics (PV), grid, and generator, to supply aeration needs in shrimp ponds. A comparative analysis of three scenarios with on-grid schemes was conducted through optimization using Queen Honey Bee Migration (QHBM) and Grey Wolf Optimization (GWO) algorithms, namely Net Present Cost (NPC), Renewable Fraction (RF), and Carbon Emission (ECO2). From a technical point of view, a lower electricity tariff is obtained compared to the grid, which is US$ 589,968. The optimization results on the NPC, RF, and ECO2 parameters show that scenario 1 of the QHBM algorithm is the most optimal. This condition is evidenced by the acquisition of 3 parameters that are closest to the determination of the objective function, yielding an NPC of US$ 230,390.34, RF of 26.01%, and ECO2 of 1,484KgCO2e, with 655Wp PV specifications and the number of PV as many as 578pcs. Economically, the investment in a solar power plant for the shrimp pond obtained BEP of 4.2 years with a payback period (PP) obtained in year 5, net cash-flow of US$ 63,317.31, with ROI of 19% and NPV of US$ 775,159.40 in the same year.

Protective Role of Cepharanthine Against Equid Herpesvirus Type 8 Through AMPK and Nrf2/HO-1 Pathway Activation

Equid herpesvirus type 8 (EqHV-8) is known to cause respiratory disease and miscarriage in horses and donkeys, which is a major problem for the equine farming industry. However, there are currently limited vaccines or drugs available to effectively treat EqHV-8 infection. Therefore, it is crucial to develop new antiviral approaches to prevent potential pandemics caused by EqHV-8. This study evaluates the antiviral and antioxidant effects of cepharanthine against EqHV-8 by employing both in vitro assays and in vivo mouse models to assess its therapeutic efficacy. To assess the effectiveness of cepharanthine against EqHV-8, we conducted experiments using NBL-6 and RK-13 cells. Additionally, we developed a mouse model to validate cepharanthine’s effectiveness against EqHV-8. In our in vitro experiments, we assessed the cepharanthine’s ability to inhibit infection caused by EqHV-8 in NBL-6 and RK-13 cells. Our results demonstrated that cepharanthine has a dose-dependent inhibitory effect, indicating that it possesses anti-EqHV-8 properties at the cellular level. Moreover, we investigated the mechanism through which cepharanthine exerts its protective effects. It was observed that cepharanthine effectively reduces the oxidative stress induced by EqHV-8 by activating the AMPK and Nrf2/HO-1 signaling pathways. Furthermore, when administered to EqHV-8 infected mice, cepharanthine significantly improved lung tissue pathology and reduced oxidative stress. The findings presented herein collectively highlight cepharanthine as a promising candidate for combating EqHV-8 infections.

Industrial Agriculture’s Influence on Recreation: The Need for a Relational Approach

Recent reviews of leisure and recreation literature have asserted a need to consider the relationship between ecosystem function and recreation at multiple spatial scales. One way socio-ecological interactions across a regional landscape impact recreation are through the industrialization of agricultural practices. Little research has examined how the industrialization of agriculture, mainly through confined animal feeding and the intensification of monocultural row crop farming, has impacted recreational opportunities in locations such as the Upper Midwest of the United States. While beach closures and fish kills attributed to non-point source pollution are glaring examples, it is likely that the relationship between industrialized agriculture and recreational opportunities is not fully understood. It is increasingly evident that a fundamental transformation of socio-ecological systems will be necessary to adapt to our changing climate and community needs. Recreation and leisure studies could play a critical role in shaping the conversation and assessing the impacts of these socio-ecological transitions.

Public, Private and Public-Private Partnerships (PPP) to Implement a One Health Approach to Combat Antimicrobial Resistance in Colombia

Abstract The establishment of public-private partnerships (PPPs) within Colombia, Latin America, is a recent, innovative effort within the nation’s agricultural industry to tackle antimicrobial resistance (AMR) under a One Health approach. PPPs are a formal alliance between representatives from the public and private sectors that aim to promote cross-sectoral collaboration, stewardship and accountability. Members agree on shared objectives and responsibilities, resources and risks to establish monitoring, prevention and mitigation activities against AMR within the farming industry. Key learnings of this initiative within the context of Colombia include: maximisation of results when monitoring is assigned to the private sector, and this may apply to other lower-middle-income countries (LMICs); objectives are better achieved when they are pre-defined according to time, budget and human resource constraints of member institutions; and confidentiality agreements must be consistent with the sensitive nature of surveillance information. Barriers to implementation were also identified, such as frequent changes of government personnel at decision making levels that make governance planning and adaptation challenging, while legal formalities and bureaucracy hinder formalisation of agreements. The success of this PPP is a useful example for other LMICs to aid in the control and prevention of animal diseases, promotion of food safety and reduction in poor animal health which limit commerce, while at the same time, minimising production loss and ensuring the provision of a fair income for producers.

Possibility of Vertical Transmission of Sarcocystis Spp. in Sika Deer in Japan.

In recent years, the wild deer population in Japan has grown exponentially, causing severe feeding damage to the agricultural and forestry industries. Therefore, the game meat industry is being promoted for effective utilization of hunted animals. Wild animals are not hygienically controlled and can serve as reservoirs for pathogenic microorganisms. However, epidemiological information on wild animals in Japan remains insufficient. Recently, food poisoning-like cases have occurred because of raw venison infection with Sarcocystis spp. As the prevalence of Sarcocystis spp. in sika deer is very high in Japan and even fawns are infected, this study attempted to verify the vertical infection of Sarcocystis spp. in sika deer in Japan. Genetic detection of Sarcocystis 18S ribosomal RNA in fetal and maternal tissues from early to late gestation in sika deer revealed Sarcocystis Types 1-5 and Sarcocystis fayeri in the mother and fetus. Types 1, 2, 4, and 5 were detected in the maternal tissues of Ezo sika deer (Cervus nippon yesoensis) in Hokkaido, whereas Types 1 and 2 and S. fayeri were detected in fetuses. Types 1-5 were detected in Honshu sika deer (Cervus nippon centralis) in Mie Prefecture but not in the fetuses. Types 1, 2, and 4 were detected in the udder and milk samples. This indicates that Sarcocystis Types 1 and 2 and S. fayeri have the ability to pass through the placenta of sika deer and invade fetal tissues and Types 1, 2, and 4 may be transmitted orally via milk. These findings suggest that there is transplacental and transmammary transmission of Sarcocystis spp. in sika deer.

Synergistic Antibacterial Effect of Lactic Acid Bacteria and Baicalin Against Staphylococcus aureus In Vitro and In Vivo.

Pathogenic bacteria such as Staphylococcus aureus (S. aureus) are the principal cause of cow mastitis, which primarily impacts milk yield and results in significant financial losses for the animal husbandry industry. Lactic acid bacteria-cell-free supernatant (LAB-CFS) and baicalin (BAI) both have a number of biological effects, including decreasing inflammation. The combined use of LAB-CFS and BAI does not appear to have been used toprotective against mastitis, however, and the underlying mechanisms are yet unknown. In this study, in vitro activity of LAB-CFS and BAI alone and in combination was determined (checkerboard experiments, time-kill curves, and flow cytometry to investigate membrane permeability) and examined the protective effects of LAB-CFS and BAI on S. aureus-induced mastitis in mice and the impact of NF-κB signaling pathways on the emergence of mastitis. We discovered that when LAB-CFS and BAI were used together, S. aureus was more effectively treated than when LAB-CFS and BAI were used separately. Flow cytometry demonstrated that LAB-CFS and BAI work together to kill bacteria. In vivo, the usage of LAB-CFS and BAI decreased the activity of myeloperoxidase, as well as IL-6, IL-1β, and TNF-α secretion and the levels of TLR2 and p65 (NF-κB) expression. These findings suggested that LAB-CFS and BAI had a preventive effect against mastitis brought on by S. aureus. Therefore, the NF-κB signaling pathway is thought to be the likely mechanism through which LAB-CFS and BAI reduced S. aureus-induced inflammation in the mammary of cows. For the treatment of cow mastitis, LAB-CFS and BAI are likely to replace antibiotics.

Oxidative Stress in Poultry and the Therapeutic Role of Herbal Medicine in Intestinal Health

The intensive broiler farming model has accelerated the development of the poultry farming industry. However, it has also inevitably brought about many stressors that lead to oxidative stress in the organism. The intestine is the leading site of nutrient digestion, absorption, and metabolism, as well as a secretory and immune organ. Oxidative stress in animal production can harm the intestine, potentially leading to significant losses for the farming industry. Under conditions of oxidative stress, many free radicals are produced in the animal’s body, attacking the intestinal mucosal tissues and destroying the barrier integrity of the intestinal tract, leading to disease. Recently, herbs have been shown to have a favorable safety profile and promising application in improving intestinal oxidative stress in poultry. Therefore, future in-depth studies on the specific mechanisms of herbs and their extracts for treating intestinal oxidative stress can provide a theoretical basis for the clinical application of herbs and new therapeutic options for intestinal oxidative stress injury during poultry farming. This review focuses on the causes and hazards of oxidative stress in the intestinal tract of poultry, and on herbs and their extracts with therapeutic potential, to provide a reference for developing and applying new antioxidants.

Labeling and sorting of avian primordial germ cells utilizing Lycopersicon Esculentum lectin.

Avian species are essential resources for human society, with their preservation and utilization heavily dependent on primordial germ cells (PGCs). However, efficient methods for isolating live PGCs from embryos remain elusive in avian species beyond chickens, and even in chickens, existing techniques have shown limited efficiency. In this study, we present a rapid, simple, and cost-effective method for labeling and sorting circulating-stage PGCs across various avian species, including Carinatae and Ratitae, using Lycopersicon Esculentum (Tomato) lectin (LEL). Notably, this method demonstrates high sorting efficiency by identifying a wide range of PGC subtypes while preserving the proliferative and migratory potential of chicken PGCs. This approach is anticipated to significantly contribute to the conservation, research, and agricultural industries related to avian species globally.

Resource allocation design method based on WSN multi-dimension soil inspection

Abstract. With the industrialization of agriculture and the sharp rise of food prices, in order to promote the intensive development of natural resources and achieve economies of scale agriculture in production, people put forward the innovative strategy of "precision agriculture" to maintain the sustainable development of agriculture. To protect the environment and farmer communities and increase productivity. However, in the special context of precision agriculture, the problems related to energy consumption and electromagnetic wave propagation in complex environments have a significant impact on precision agriculture. In the case of no monitoring and harsh environment, wireless sensor networks (WSN) can complete the tasks of real-time monitoring and information collection. In the past, the understanding of WSN in agriculture was limited to unilateral detection, which led to the underutilization of the soil. This paper introduces an innovative solution for precision agriculture based on wireless sensor networks, which mainly focuses on the observation and impact assessment of soil water volume,PH value, temperature and pressure in agricultural production process. It aims to reduce the waste of natural resources and the use of fertilizer substances, while maintaining or improving the yield of farming, in order to better promote the development of WSN in the agricultural field.
