The aim of this study was to identify herd- and management-related risk factors for lameness, describe dairy cattle production practices in Egypt, and assess farm personnel's knowledge and perceptions of common foot lesions associated with lameness. A cross-sectional study of 16,098 dairy cows from 55 farms was conducted. Milking cows were visually assessed for locomotion as they exited the milking parlor using a 0-3 scoring system. The within-herd prevalence of lameness was calculated as the proportion of cows scoring ≥ 2. Management data were collected through structured questionnaires with farm managers, combined with direct observations and measurements on the farms. Farm personnel responsible for lameness management were evaluated on their ability to identify and provide information about the causes and treatments of seven common foot lesions using pictorial descriptors. A mixed-effects logistic regression model incorporating Farm ID as a random-effects variable was used to investigate risk factors for within-herd lameness prevalence. The final model revealed that adequate footbath disinfectant concentration (OR = 0.28, 95% CI: 0.16-0.5) and increased bedding abrasiveness (OR = 0.30, 95% CI: 0.15-0.6) were significantly associated with reduced odds of lameness, while sharp corners at the parlor exit were associated with increased lameness prevalence (OR = 1.9, 95% CI: 1.1-3.4). A significant interaction was observed between footbath disinfectant concentration and bedding abrasiveness (OR = 3.3, 95% CI: 1.1-9.8), indicating that the association between bedding type and lameness prevalence was modified by footbath adequacy. Specifically, bedding type was associated with lameness only when footbath disinfectant concentration was inadequate, while under adequate footbath conditions, lameness prevalence was uniformly low regardless of bedding type. Knowledge gaps were identified among farm personnel in diagnosing and treating lameness. These findings highlight the importance of optimizing footbath management and bedding quality to mitigate lameness risk and provide evidence-based recommendations for improving lameness prevention and animal welfare in Egyptian dairy herds. Implementing educational programs and establishing a foot-trimming certification body in Egypt could further enhance the capability of farm personnel in effectively managing foot lesions.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 7","pages":"352"},"PeriodicalIF":1.7,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144790124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detection of BCoV on surfaces and fomites in dairy facilities is rarely reported. We examined the presence of BCoV on various surfaces of a dairy farm with previous BCoV-positive cattle. A total of 61 samples were collected, including 37 samples of surfaces and fomites from the housing of suckling calves, weaned calves, heifers, and lactating cows. Fecal samples (n = 13) and nasal secretions (n = 11) were collected from calves and cows. Molecular identification of BCoV was performed using semi-nested RT-PCR. Amplicons of BCoV genes N and S1 from three positive samples (environment, diarrheic feces, and nasal secretions) were selected for nucleotide (nt) sequencing analysis. BCoV RNA was detected in 27% (10/37) of environmental samples, including wooden surfaces, concrete and tiles, plastic feed troughs, drinkers, and calf bottles. Furthermore, BCoV RNA was amplified in 46.1% of fecal and 36.4% of nasal secretion samples. Analysis of the N gene revealed 100% nt similarity between strains from different sources, while the S1 gene showed 99.7 to 99.8% similarity. The same BCoV strain was detected in cattle and on the evaluated surfaces. These strains were ancestrally different from the prototype strains but clustered with other Brazilian field strains. In conclusion, BCoV is present in cattle and on different surfaces within the environment of the evaluated dairy cattle farm. Biosecurity measures, such as cleaning and disinfection, are crucial to mitigate infection risk, especially for calves.</p>","PeriodicalId":23329,"journal":{"name":"Tropical animal health and production","volume":"57 7","pages":"344"},"PeriodicalIF":1.7,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144785434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 600 Lohmann White layer hens at 64 weeks of age were assigned into 5 treatment groups, with 3 replicates, consisted of the control diet, control group (no supplementation of Zn, Mn and Cu; CG), supplementation of calcium carbonate (CaCO₃) as a carrier of Zn, Mn and Cu sulphate (CCS), sulphate form of Zn, Mn and Cu combination (SF), glycine chelated of Zn, Mn and Cu combination (GC), and Zn + Mn - methionine (Met) chelated, Cu - lysine (Lys) chelated (MLC) group. Hen-day egg production tended to be higher in the GC and MLC groups during experimental period (P < 0.001). It changed between 79.7% and 83.4% in GC and MLC groups between 64 and 75 weeks of age. At 69 and 75 weeks of age, the highest value of egg weight was observed in the GC group with values of 66.8 g and 67.1 g, respectively (P < 0.001). The supplementation of MLC caused an enhancement in villus size, including villus height and surface area, in both duodenum and ileum (P < 0.001). In the duodenum, the villus height was found to be the highest with a value of 2583.2 μm in the CCS group, whereas the villus width was higher in SF (349.9 μm) and MLC (391.7 μm) groups (P < 0.001). In the jejunum, SF caused a stimulation effect for villus efficiency, by increasing villus height (2512.6 μm), villus apparent surface area (723680 µm²), crypt depth (291.1 μm), and VH/CD (9.4, P < 0.05). Zn, Mn and Cu combination in glycine chelated and methionine-lysine chelated forms caused an increment in height of villus in the ileum part of small intestine (1421.7 μm in GC and 1388.0 μm in MLC) when compared other supplementation groups (P < 0.001).
