    KNOWLEDGE, ATTITUDE AND PRACTICE ASSESSMENT OF CATTLE OWNERS ON LUMPY SKIN DISEASE IN SELECTED DISTRICTS OF EASTERN AND SOUTHEASTERN ZONES, TIGRAY, ETHPIOPIA
    (Mekelle University, 2023-11-25) TEKLEHAIMANOT GEBREMICHAEL
    A cross-sectional study design was conducted from April, 2021 to August, 2021, to assess knowledge, attitudes, and practices of cattle owners about LSD and review its occurrence selected districts of Eastern and Southeastern zones, Tigray. Primary and secondary data were collected. For the primary data a questionnaire surveys and FGD and KII were undertaken. A total of 438 questionnaires, 9 FGD and 12 KII were undertaken. The collected data were analyzed using STATA, descriptive statistics (expressed in terms of frequency and percentage) and univariate logistic regression were employed (expressed in terms of OR and 95% CI). In the current study majority of the respondents were in the age group of 31-40year (49.3%), male (92.5%), illiterate (52.1%) and farmer (75.3%). Majority of them had unfavorable attitude (69.8%) and poor practice (66.7%) toward LSD. Majority of the respondents (68.5%) identify LSD from other illnesses by nodular lesions and 53.0% believe that treating external parasites will reduce LSD infection. Eighty four percent of the respondents did not handle good management, 60.3% didn’t clean pen of cattle regularly and 85.6% did not receive any training about sick animal handling. Knowledge of cattle owners on LSD from Enderta, Adigudem and Wukro districts were 2.16 (OR= 2.16, 95% CI: 1.008, 4.563), 2.15 (OR = 2.15; 95% CI: 0.977, 4.757) and 2.07 (OR=2.07; 95% CI: 0.881, 4.889) times higher as compare to cattle owners of Tsrae-wenberta, respectively. Respondents in the age group of > 50 years old were 1.84 times higher likely to have positive attitude towards the disease compared to owners in the age group of 31-40 years old and the difference was statistically significant (OR=1.84,95% CI :1.091,3.108). Respondents who uses individual grazing land and individual ground water had 1.91 (OR= 1.91; 95% CI: 1.262, 2.893) and 2.80 (OR=2.80,95%CI: 1.476, 5.327) times better LSD prevention and control practice compared to cattle owners uses communal grazing land and dump, respectively. In conclusion, poor sick animal handling practice, poor animal pen hygienic, and inadequate information and training was encountered among respondents of the present study. Therefore, proper handling of sick animals, cleaning and disinfecting of pens and awareness creation need to be implemented

    COPROLOGICAL STUDY OF TREMATODE INFECTIONS AND ASSOCIATED FACTORS IN CATTLE AND SHEEP AND SPATIAL DISTRIBUTION OF FRESHWATER SNAIL IN SOUTH AND SOUTHEASTERN ZONE OF TIGRAY, ETHIOPIA
    (Mekelle University, 2025-01-25) Girmay Gebrezgi
    Trematode infections are a significant cause of disease and economic losses worldwide. However, limited research has been conducted in the South and Southeastern zones of Tigray, Ethiopia, regarding the local epidemiology, transmission dynamics, and management strategies. To address this gap, a cross-sectional study was conducted from December 2023 to December 2024 to investigate the prevalence of trematode infections in cattle and sheep and the spatial distribution of freshwater snails in these areas. Simple random sampling was used to select study animals, and descriptive statistics were computed using STATA version 16. In total, 1536 fecal samples (768 from cattle and 768 from sheep) were examined, alongside snail collection. Additionally, 13 laboratory-bred mice were exposed en masse to Schistosoma cercariae for confirmation of transmission. The study revealed that the majority (60.29%, 463/768) of cattle and 53.5% (411/768) of sheep had either single or multiple trematode infections. Among cattle, 19.01% were testing positive for fasciolosis, while 20.7% exhibited mixed infections of Fasciola and Paramphistomum species. In sheep, 21.74% were positive for fasciolosis and 18.23% for mixed infections. The South zone had the highest prevalence in both cattle and sheep. Furthermore, most of the positive rates were exhibited in adult cattle with poor body condition scores while in adult sheep with medium body condition scores. Logistic regression showed a significant association between zone and bovine fasciolosis (OR = 1.76; P = 0.000), but no significant association for ovine fasciolosis. A total of 1269 snails were collected, identified as Biomphalaria pfeifferi, Bulinus truncatus, and Lymnaea natalensis. Intermediate hosts for schistosomiasis collected during the survey were found to be shedding Schistosoma cercariae. Furthermore, en masse cercariae-exposed laboratory-bred mice confirm the active transmission of schistosomiasis in the study area. The study highlights the trematode infections and the heterogeneous distribution of snails in the study area are a significant health concern for cattle and sheep, underlining the need for targeted control measures to mitigate the public health and economic impacts in the region
