Coccidiosis caused by Eimeria tenella significantly impairs poultry health and productivity, prompting the search for alternative or complementary therapies to conventional coccidiostats. This study investigates the prophylactic and therapeutic efficacy of a probiotic complex of Lactobacillus, Bifidobacteria, Enterococcus, and Streptococcus, alone or in combination with amprolium, against E. tenella infection in broiler chickens. A total of 90 broiler chickens were randomly allocated into six experimental groups (n = 15/group). Group 1 served as the uninfected control, while Group 2 comprised infected but untreated controls. Group 3 received probiotics at a concentration of 1 mg/mL, and Group 4 was treated with amprolium at a dosage of 20 mg/kg. Group 5 was administered a combination of probiotics (1 mg/mL) and amprolium (20 mg/kg), whereas Group 6 received prophylactic treatment with probiotics (1 mg/mL). All groups except the uninfected control were challenged orally with 2 × 104 sporula-ted E. tenella oocysts. Growth performance was monitored on days 15, 21, and 28. Lesion scoring, oocyst shedding, and histopathological examinations were conducted on day 28. An in vitro sporulation assay evaluated the inhibitory potential of treatments on oocyst development. In vitro, the probiotic-amprolium combination significantly reduced oocyst sporulation rates (5.86%). In vivo, amprolium and prophylactic probiotics significantly improved body weight gain and feed intake (p < 0.05) and reduced oocyst shedding. Lesion severity and parasite stage counts were significantly lower in the amprolium group; however, the combination group exhibited unexpectedly higher lesion scores. Mortality was highest in the amprolium and untreated groups (20%) but absent in the combination group, suggesting differential immunomodulatory effects. Histopathological analysis confirmed reduced intestinal damage in groups treated with amprolium or prophylactic probiotics. Amprolium monotherapy and prophylactic probiotic supplementation were effective in mitigating E. tenella-induced pathology and improving broiler performance. Probiotics alone provided moderate benefits, while their post-infection therapeutic use or co-administration with amprolium did not yield superior results. These findings underscore the prophylactic value of probiotics and warrant further studies to optimize combination regimens under field conditions.

Feed cost constitutes a major constraint in small ruminant production systems in Jordan. The search for alternative, cost-effective feed ingredients has prompted interest in coconut meal (COC), a by-product of coconut oil extraction. This study evaluated the effects of including 10% COC (COC10) in the diet on the growth performance, nutrient utilization, carcass characteristics, and meat quality of growing Awassi lambs. Twenty-four male Awassi lambs (17.2 ± 0.63 kg) were randomly assigned to two dietary treatments: A control diet without COC (CON) and a test diet with 100 g/kg dry matter (DM) COC (COC10). The feeding trial lasted 70 days, comprising a 7-day adaptation and a 63-day experimental period. Feed intake and growth performance were monitored throughout. On day 49, five lambs per group were used to assess nutrient digestibility and nitrogen balance using total fecal and urine collection in metabolic cages. On day 64, lambs were slaughtered to evaluate carcass characteristics and meat quality. Blood samples were collected for serum biochemical analysis. The inclusion of COC10 significantly increased acid detergent fiber and ether extract intake (p ≤ 0.05), with no adverse effects on DM intake, weight gain, feed efficiency, or nutrient digestibility (p > 0.05). Economic analysis revealed a 16% reduction in production cost per kg of weight gain in the COC10 group (p = 0.05). No significant effects were observed on carcass traits, meat quality parameters, or blood biochemical profiles. Incorporating COC10 into the diet of Awassi lambs had no detrimental impact on growth, carcass characteristics, or health status, while improving economic efficiency. COC is a viable alternative protein and energy source in lamb diets. Further research is warranted to determine optimal inclusion rates under varying production systems.

The rising burden of antimicrobial resistance (AMR) in veterinary medicine poses significant threats to animal and public health. In South Africa, inadequate surveillance exacerbates the challenge, particularly regarding Staphylococcus spp. infections in companion animals. This study aimed to investigate the patterns and predictors of AMR and multidrug resistance (MDR) in Staphylococcus isolated from dogs between 2012 and 2017. A retrospective cross-sectional study was conducted on 1627 Staphylococcus isolates. Data regarding animal demographics and antimicrobial susceptibility were extracted, cleaned, and analyzed. Intermediate susceptibility results were classified as resistant. AMR was defined as resistance to at least one antimicrobial class and MDR as resistance to three or more classes. Descriptive statistics, Cochran–Armitage trend analysis, and binary logistic regression models were employed to assess trends and predictors of AMR and MDR. Overall, 61.2% of isolates exhibited resistance to at least one antimicrobial, and 39.0% were classified as MDR. The highest resistance was observed against penicillins (39.64%), followed by aminoglycosides (22.31%). Significant predictors of AMR included Staphylococcus species, specimen type, and year of isolation, while MDR was significantly associated with specimen type and the age of the dog. Notably, Staphylococcus pseudintermedius showed a markedly higher likelihood of resistance (adjusted odds ratio = 2.23, p < 0.001) compared to other species. Temporal trends indicated a decrease in AMR but an increase in MDR across the study period. The high prevalence of AMR and MDR among canine Staphylococcus isolates, particularly in skin infections and among younger dogs, underscores the urgent need to strengthen antimicrobial stewardship, enhance surveillance systems, and target interventions in veterinary practice. These findings serve as critical baseline data for future assessments of AMR trends and can be used to inform strategies to mitigate the dissemination of resistant pathogens between animals and humans.

Postpartum reproductive disorders, particularly metritis and placental retention, significantly compromise dairy herd productivity and calf viability. In Vietnam, where dairy production is expanding, limited data exist on the prevalence and consequences of such disorders under modern farm conditions. This study aimed to determine the prevalence of metritis and placental retention in dairy cows on an industrial farm in southern Vietnam from 2022 to mid-2024 and to evaluate their reproductive and neonatal health consequences. A longitudinal study was conducted on a dairy herd monitored through skin conductance responses activity sensors and DataFlow™ II software (Allflex Livestock Intelligence, MSD Animal Health Intelligence, USA). Health alerts triggered clinical examinations to identify genital infections. Metritic cows were treated using antibiotics and hormonal therapies and were monitored for recovery and subsequent breeding success. Neonatal calves were examined for respiratory and gastrointestinal disorders for 21 days post-birth. Statistical analysis was performed using Chi-square tests at a 95% confidence level. Genital infections affected 23.5%–38.8% of cows annually, with metritis prevalence ranging from 7.2% to 9.8%. Placental retention remained consistent at approximately 13% across years. Quarter 2 consistently exhibited the highest incidence of reproductive disorders. Treatment success for metritis was high (85.8%–88.6%); however, post-treatment pregnancy rates declined over time (68.5% in 2022 and 54.8% in 2024). Neonatal respiratory infections (2.9%–4.4%) were more frequent than gastrointestinal infections (0.1%–0.8%), with calf mortality declining from 3.4% in 2022 to 0.7% in 2024. Metritis and placental retention remain prevalent challenges in Vietnamese dairy herds, adversely impacting reproductive efficiency and calf health despite high treatment efficacy. The seasonal spike in disease incidence underscores the need for tailored herd health management during hotter months. Although early detection through precision monitoring improved recovery outcomes, residual effects on fertility persisted. Strengthened periparturient care, postpartum surveillance, and colostrum management are recommended to enhance both maternal and neonatal health outcomes.

Equine infectious anemia (EIA) is a lentiviral disease affecting members of the Equidae family, with global distribution and significant implications for animal health and biosecurity. Despite numerous individual reports, a comprehensive synthesis of its global prevalence and risk factors remains lacking. This study aimed to conduct a systematic review and meta-analysis to estimate the global prevalence of EIA, identify diagnostic trends, and evaluate factors associated with heterogeneity across studies. A systematic search was conducted in six major databases (PubMed, Scopus, Web of Science, ScienceDirect, Cochrane Library, and ProQuest), yielding 312 records. After Preferred Reporting Items for Systematic Reviews and Meta-Analyses-guided screening, 29 eligible studies published between 1975 and 2024 were included in the study. Meta-analysis was performed using R Studio (version 4.4.2) employing a random-effects model. Subgroup analyses and meta-regression were conducted to explore heterogeneity across host species, continent, diagnostic method, and study period. Publication bias was assessed through funnel plots and Egger’s test. The global pooled prevalence of EIA was estimated at 20.97% (95% confidence interval [CI]: 11.08–30.85), with substantial heterogeneity (I2 = 99.3%). South America reported the highest regional prevalence (27.21%), while horses showed the greatest susceptibility among Equidae (25.40%). Diagnostic methods varied, with agar gel immunodiffusion being the most commonly used (18.62% prevalence detection). A declining trend in prevalence (2.19%–28.70%) was noted from 2015 to 2022. No significant publication bias was detected. Meta-regression revealed that climate and study period partially explained the heterogeneity. This study highlights the substantial global burden and diagnostic variability of EIA, emphasizing the need for enhanced surveillance in endemic areas, standardized diagnostic protocols, and strengthened quarantine practices. Expanding serological monitoring in underrepresented regions and integrating climatic and ecological data into control strategies are vital for mitigating EIA transmission risks.

Despite the profound cultural and ecological significance of falcons in the Arabian Gulf, systematic evaluations of regional falcon research are lacking. A bibliometric approach can elucidate the evolution, influence, and emerging priorities within this specialized field. This study aimed to provide the first comprehensive bibliometric mapping of falcon research in the Arabian Gulf countries over the past four decades (1984–2024), revealing research dynamics, international collaboration networks, thematic trajectories, and critical knowledge gaps. Original research articles were systematically retrieved from the Scopus database using targeted search strategies restricted to title-level keywords and affiliation filters. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 126 articles were selected for analysis. Bibliometric methods – including co-authorship networks, keyword co-occurrence, thematic mapping, and trend analysis – were applied using VOSviewer, Bibliometrix, and Excel. The research output exhibited a modest annual growth rate of 2.32%, predominantly driven by contributions from the United Arab Emirates and Saudi Arabia. Strong international collaborations (56.35% co-authored publications) were identified, particularly with European and North American institutions. Research themes historically centered on clinical veterinary topics and avian biology are now shifting toward molecular diagnostics, genetic studies, and disease surveillance. However, a clear regional imbalance and underrepresentation of emerging fields such as genomics, epidemiology, and conservation breeding were observed. This analysis underscores the need for an integrative, regionally inclusive research strategy incorporating advanced molecular technologies and conservation science. Strengthening cross-border collaboration, adopting genome-based monitoring, and addressing emerging infectious threats will be critical to advancing falcon research and preservation in the Arabian Gulf.
