Gastrointestinal nematodes (GINs) remain a significant challenge to productivity and sustainability in beef cattle systems in the United States, contributing to subclinical reductions in growth, reproductive performance, and overall herd health across production stages. Control programs have historically relied on routine anthelmintic use; however, increasing reports of anthelmintic resistance highlight the need for alternative management strategies. This narrative review synthesizes peer-reviewed literature identified through targeted searches of major scientific databases spanning approximately seven decades, with articles selected for relevance to GIN epidemiology, diagnostics, and control in beef cattle. Particular emphasis is placed on life stage-specific susceptibility, host immune development, and the role of diagnostic tools in guiding evidence-based interventions. The review further examines non-anthelmintic strategies such as grazing management, nutritional supplementation, selective breeding, and integrated parasite management practices adapted from small ruminant systems. Across studies, young and immunologically developing cattle experience the greatest productivity losses, while mature animals contribute disproportionately to pasture contamination, reinforcing the importance of targeted control measures. Overall, the literature supports a transition toward integrated, diagnostics-driven parasite control programs that sustain productivity and animal well-being while preserving long-term anthelmintic efficacy.
Agricultural sustainability is becoming more and more important for human health. Wireless sensing technology could provide smart monitoring in real time for different parameters in planting, breeding, and the food supply chain with advanced sensors such as flexible sensors; wireless communication networks such as third-, fourth-, or fifth-generation (3G, 4G, or 5G) mobile communication technology networks; and artificial intelligence (AI) models. Many sustainable, natural, renewable, and recycled facility energies such as light, wind, water, heat, acoustic, radio frequency (RF), and microbe energies that exist in actual agricultural systems could be harvested by advanced self-powered technologies and devices using solar cells, electromagnetic generators (EMGs), thermoelectric generators (TEGs), piezoelectric generators (PZGs), triboelectric nanogenerators (TENGs), or microbial full cells (MFCs). Sustainable energy harvesting to the maximum extent possible could lead to the creation of sustainable self-powered wireless sensing devices, reduce carbon emissions, and result in the implementation of precision smart monitoring, management, and decision making for agricultural production. Therefore, this article suggests that proposing and developing a self-powered wireless sensing system for sustainable agriculture (SAS) would be an effective way to improve smart agriculture production efficiency while achieving green and sustainable agriculture and, finally, ensuring food quality and safety and human health.
Abstract Background Florfenicol is a broad-spectrum antimicrobial approved in many countries for treating bacterial infections in production animals. Although florfenicol has been widely used in the US catfish industry, its impact on the native microbiota within catfish tissues remains largely unknown. Florfenicol treatment is followed by a mandatory withdrawal period to ensure drug residues fall below regulatory limits before harvest. This interval also allows for the potential recovery of the native microbiota. In particular, the skin and gill microbiota have often been overlooked in aquaculture microbiome research. Moreover, the dynamics of microbial communities and resistome profiles following drug withdrawal are still poorly understood, despite their ecological significance. Results A significant increase in intestinal microbial diversity was observed at the end of the withdrawal period. The highest alpha diversity (Shannon index) was observed in catfish intestines. This increase indicated the restoration of the normal microbiota in catfish intestine. The predominant bacterial phyla shared among catfish gill, intestine, and skin are Proteobacteria (62%), Bacteroidetes (18%), Actinobacteriota (12%), Firmicutes (3%), Patescibacteria (2%), and Verrucomicrobiota (1%). Florfenicol application can have lasting effects through the withdrawal period, particularly altering the intestinal microbial community. Conclusion The result of this study underscores the impact of florfenicol treatment on the bacterial landscape and antibiotic resistance in catfish, highlighting significant changes in microbial composition in the catfish intestine and at the end of the withdrawal period. These findings address the need for monitoring and managing antibiotic resistance in fish farming environments.

This study explores the nutritional benefits and health implications of omega-3- and omega-6-enriched eggs, positioning them within the context of functional foods aimed at improving public health outcomes. With rising consumer interest in nutritionally fortified foods, omega-enriched eggs have emerged as a viable source of essential fatty acids, offering potential benefits for cardiovascular health, inflammation reduction, and cognitive function. This research examines enrichment techniques, particularly dietary modifications for laying hens, such as the inclusion of flaxseed and algae, to enhance omega-3 content and balance the omega-6-to-omega-3 ratio in eggs. The findings indicate that enriched eggs provide significantly higher levels of essential fatty acids and bioactive compounds than conventional eggs, aligning with dietary needs in populations with limited access to traditional omega-3 sources like fish. This study further addresses consumer perception challenges, regulatory constraints, and environmental considerations related to sustainable production practices. The conclusions underscore the value of omega-enriched eggs as a functional food that aligns with health-conscious dietary trends and recommend ongoing research to refine enrichment methods and expand market accessibility.

Agriculture is a vital component of Egypt's economy; therefore, using Digital Elevation Models (DEMs) in agricultural planning in Egypt has significant benefits regarding water management, site appropriateness assessment, flood risk mitigation, and infrastructure construction. It is also essential for planners to make more informed decisions, optimize resource allocation, and support sustainable farming practices. This research paper investigates the accuracy of obtaining DEM data from four free global models (STRM30, ALOS30, COP30, and TanDEM-X90). The global DEM data has been compared to an actual GNSS-RTK DEM data surveyed onsite for two agricultural block areas in Aswan, the southern Government of Egypt. The two blocks are a part of a national project. For Block I and II, the RMSE of the Model STRM30 was 2.92 m and 3.59 m, respectively, indicating a poorer solution. Regarding accuracy, the ALOS30 model ranks third, reporting an RMSE of 2.58 m for block II and 3.30 m for block I. COP30 has an RMSE value of 1.06 m for blocks I and II and.91 m overall. TanDEM-X90 is the most accurate model in this investigation; block I provided an RMSE of 0.90 m with an SD of 0.58 m (SD95% = 0.38 m). After removing the anomalies, the model's stated RMSE for block II was 0.34 m, with an SD value of 0.62 m and 1.03 m. According to the classification using machine learning algorithms, with an accuracy of 84.7% for block I and 85% for block II, TanDEM-X90 is the best solution.
This study investigated the effects of treated wastewater irrigation on physiological traits and gene expression in pepper (Capsicum annuum) plants during early development. Control (tap water) and treated wastewater treatments were compared, and physiological parameters, including SPAD values and leaf color measurements, were assessed. In addition, the expression levels of stress-related genes CaCAT2, CaDREB32, and CaLOX1 were analyzed using RT-qPCR. The results showed that treated wastewater irrigation significantly enhanced leaf chlorophyll content and caused a shift in leaf coloration toward darker, greenish tones. At the molecular level, a moderate upregulation of CaCAT2 was detected, whereas CaDREB32 exhibited only a slight and statistically insignificant change. The most pronounced response was observed for CaLOX1, which showed an approximately 50% increase in expression under treated wastewater treatment compared with the control. These findings suggest that treated wastewater irrigation can temporarily enhance photosynthetic capacity in pepper plants, while concurrently activating stress-related signaling pathways. This dual effect highlights that the agricultural use of treated wastewater entails potential benefits but also carries long-term risks that must be carefully considered.
Citrus melanose consists of a series of plant diseases caused by the fungal species of the genus Diaporthe. It has been reported with over 30 Diaporthe species on citrus, including several important fungal pathogens, endophytes, saprophytes, and also latent fungal pathogens with an endophytic/saprophytic lifestyle. Among them, the disease symptoms caused by Diaporthe citri are complex, and the black spots and sand skin symptoms produced on fruits and leaves are the most serious harm to citrus. Currently, the primers and methods for the detection of D. citri have been constructed, and are supposed to be used in field monitor of the dynamics of the pathogen and the epidemiology of the caused diseases. In the orchard, the infection and outbreak of melanose is highly correlated to the orchard damage by natural disasters and continuous rainfalls, the main disease control strategy should be the combination method of agricultural control, physical control, and chemical control.For the agricultural control, the dead woods, twigs, and leaves should be cleared to reduce the formation of infection sources; for the physical control, it is important to avoid plant wounds by cold and sunburn, and the conidia spread by rains; for the chemical control, the usage of fungicides should be protective to the plant wounds, and also over the period of rainfalls. In addition, the research of the biological control of citrus melanose is still in its infancy, several studies have isolated different antagonistic microorganisms and tested their effects on the control of citrus melanose, which suggest their promising roles as supplementary fungicides. This review summarized the major research progresses of citrus melanose at home and abroad, and aimed to offer some insights to the control of the disease.
Climate change is now evident and severe water shortage due to unpredictable raining season along with extended summers is expected to hamper crop production across the globe. Application of nanoparticle based formulations is one of the most sought after approach that is being explored currently to alleviate drought stress impact on plants. The present study was aimed to evaluate the potential of biosynthesized silica nanoparticles (silica NPs) in improving the drought tolerance of wheat. Four different concentrations of silica NPs (30, 60, 90, and 120 ppm) were used to treat wheat plants grown under two irrigation regimes- 50% soil moisture content (drought) and 100% soil moisture content (well-watered). The induced drought caused a prominent reduction in both - the crop yield and the morphological parameters of the crop. Foliar application of silica NPs at all concentrations, increased the plant's tolerance towards water stress but 60 ppm concentration was found to be most effective amongst all. After treatment with silica NPs at 60 ppm concentration, the plant height increased by 8.28%, spikes per plant by 98%, seeds per spike by 12.4%, and thousand seed weight by 37.5% as compared to the control. Besides this, expression levels of four drought-stress responsive genes-ABC1, Wdhn13, CHP, and EXP2 was also studied. We observed an enhanced expression of all the stress genes after treatment with silica nanoparticles in wheat plants grown under water deficient conditions, clearly supporting the influence of NP treatment at gene/molecular level. In nutshell, we conclude that silica nanoparticles have the potential to significantly ameliorate the negative impact of drought stress by reviving plant growth and modulating gene expression.
The aim of this trial was to investigate the effects of dietary protein and lipid levels on growth performance and flesh quality of largemouth bass (Micropterus salmoides). A 3 × 3 two-factor design was used, including three crude protein levels of 46%, 50%, 54% (P46, P50, P54) and three crude lipid levels of 8%, 12%, 16% (L8, L12, L16). Thus, a total of nine diets (P46/L8, P46/L12, P46/L16, P50/L8, P50/L12, P50/L16, P54/L8, P54/L12 and P54/L16) were prepared and fed to large-size largemouth bass with initial body weight of 109.7 g for 84 days. At the same dietary protein level, weight gain rate (WGR), protein efficiency rate (PER), viscerosomatic index and polyunsaturated fatty acids (PUFAs) percent in flesh showed an increasing trend with increasing the dietary lipid level, while feed conversion ratio (FCR) showed a decreasing trend. At P46 and P50, whole fish crude protein, muscle crude protein, total collagen content, hardness, springiness, chewiness and shear force increased, and steaming loss and freezing loss decreased with increasing the dietary lipid level, while the above indicators showed an opposite trend at P54. At P50, the protein retention (PR) of 16% crude lipid group was significantly higher than that in the 8% and 12% crude lipid groups (P < 0.05). At the same dietary lipid level, the 50% and 54% crude protein groups presented higher WGR and lower FCR than the 46% crude protein group. The P54/L16 group had the highest WGR (184.4%) and lowest FCR (0.92) among all the groups, but the P50/L16 group presented similar WGR and FCR to the P54/L16 group (P > 0.05). The P50/L16 group showed the highest PER, PR, whole fish protein, muscle protein, total collagen, PUFAs, muscle hardness, springiness, chewiness, shear force and the lowest steaming loss. In conclusion, based on growth performance and flesh quality, the appropriate dietary protein and lipid requirements for large-size largemouth bass were 50% and 16%, respectively.

Soil pH is the most important factor in evaluating plant nutritional status due to its close association with nutrient availability. In the 2018 and 2019 seasons, two field experiments were conducted to evaluate the performance of olive trees (<i>Olea europaea</i>, Picual cv.) grown in sandy clay loam soil under multi-abiotic stresses with the application of three different acidifying agents (AAs), acetic (AC), citric (CA), and sulfuric (SA) acid, at two doses (25 and 50 cm<sup>3</sup>; AC<sub>1</sub> and AC<sub>2</sub>, CA<sub>1</sub> and CA<sub>2</sub>, and SA<sub>1</sub> and SA<sub>2</sub>, respectively), as compared with a control treatment. This study was established according to a randomized complete block design. In general, our results showed that all the AAs applied surpassed the control treatment with respect to all the studied parameters except for the leaf iron content. Furthermore, the trees treated with CA yielded the best results in terms of the leaf nitrogen, calcium, and magnesium contents; the physiological and growth parameters (except for the performance index); the total fruit weight, flesh weight, and flesh dry matter; the fruit diameter; the oil content; and the total olive yield. Furthermore, the maximum leaf potassium, manganese, zinc, and copper contents were obtained in the trees growing in soil injected with AC. The correlation coefficient fluctuated between positive and negative among the studied characteristics.

Le conflit qui a débuté en 2012 a fortement affecté les campagnes centrafricaines, déjà fragilisées par des décennies de marginalisation et par les précédentes crises sécuritaires. Pillages et insécurité prolongée déstabilisent les villages. Tant individuellement que collectivement, les paysans tentent de s’adapter à ce contexte de crise et aux transformations qu’il induit. Mais face à une insécurité qui demeure forte, beaucoup ne parviennent qu’à résister au quotidien à l’adversité vécue. La résilience des paysans, tant souhaitée par les acteurs de l’aide humanitaire, demeure peu apparente dans ces campagnes.
Au Maroc, la forêt constitue une réserve pastorale à longueur d’année, et produit, en année normale, 1,5 milliard d’unités fourragères soit 17% du bilan fourrager national. La question pastorale constitue l’un des facteurs de désertification des formations forestières dans un contexte bioclimatique où l’aridité touche plus de 93% du territoire national. C’est ainsi que le département des Eaux et Forêts et ses partenaires ont élaboré en 2016 une stratégie sylvopastorale nationale. La vision retenue consiste à ce que les ressources sylvopastorales soient gérées durablement dans le long terme moyennant la bonne gouvernance de tous les biens, services que recèlent les territoires forestiers. Cette stratégie sylvopastorale traite des questions de restauration des écosystèmes naturel.
