Major Causes of Liver Condemnation and Associated Direct Financial Losses in Bovine Saughtered at Assela Municipal Abattoir Arsi, South Eastern Ethiopia
A study was conducted from October, 2013 to March, 2014 on cattle slaughtered at Assela municipal abattoir with the aim of determining major causes of liver condemnation and to estimate the direct financial losses attributed to the condemned liver. Ante mortem and post mortem inspection procedures were followed throughout the study and abnormalities encountered were recorded. A total of 384 cattle were examined at ante mortem and 9 animals were found to have abnormalities/conditions like lameness, blindness, rough hair, amputated tail and branding. Out of 384 cattle slaughtered, 274 (71.4%) livers were totally condemned. The major causes of liver condemnation were due to hydatidosis (64.6%), fascilosis (20.8%), calcification (7.7%), coinfection of hydatid cyst with fasciola (4.7%), cirrhosis (1.5%) and abscess (0.7%). Comparison of liver condemnation rate was carried out for different age, animal origin and body condition however, statistically significant difference was observed only between age groups. The direct financial loss due to liver condemnation was calculated to be 418,761 ETB per annum, rendering them unfit for local market for eusthetic reason or considering their zoonotic risks to human beings. To this end, public education on the effects of animal disease, application of strict control measures accompanying epidemiological studies and exercising appropriate meat inspection procedures were forwarded to minimize liver condemnation and as well as to safeguard the welfare of the public.
Study on Prevalence and Monetary Loss Attributed to Hydatidosis in Cattle Slaughtered at Jimma Municipal Abattoir, Southwestern Ethiopia
A cross-sectional study was conducted on bovine hydatidosis from November 2015 to June 2016 with the objectives of investigating its prevalence and Monetary loss in cattle slaughtered in Jimma municipality abattoir. Routine ante mortem and post-mortem inspection was performed on a total of 400 selected slaughtered cattle. Infection organs 223 cattle positive, 200 (89.7%) had cysts more in lungs, 20 (8.9%) in liver, 1 (0.45%) in kidney, 1(0.45%) in spleen, whereas, the rest of 1(0.45%) in heart infections involved organs. A significant association was observed (P<0.05) between the disease positivity and age groups, body condition. It was concluded that these zonotic cestodes deserve due attention to safeguard public health and that further studies are needed on epidemiology and public health importance of Echinococcus granulosus in the study area.
Prevalence of Bovine Trypanasomosis in Guto Gida District of East Wollega Zone, Oromia Regional State, Ethiopia
A cross sectional study was carried out to determine the prevalence of bovine trypanosomosis in five peasant associations of Guto Gida District of East Wollega Zone, Ethiopia from October 2013 to March 2014. From five peasant association, 384 cattle were randomly selected and examined for trypanosomosis. The overall prevalence of bovine trypanosomosis was 7.81% of which Trypanosoma congolense infection was 53.33%, Trypanosoma vivax infection was 30% and Trypanosoma brucei was 16.66% with statistically significant difference (P=0.00). A significant association was observed (P<0.05) between the disease positivity and body condition score. When the mean packed cell volume of trypanosome infected animals was compared with that of non- infected animals, it was significantly lower (P<0.05) in the infected animals. In conclusion, trypanosomosis caused by T. congolense, T. vivax and T.brucei with more prevalence of T. congolense remained the main constraint to animal production and agricultural development in study area.
