Study on Prevalence and Economic Significance of Bovine Hydatidosis in Bako Muncipal Abattoir, West Shoa Zone, Oromiya Regional State

Abstract

A cross-sectional study aimed at determining the prevalence and cyst characteristics and estimating the financial loss due to cystic echinococcosis (hydatidosis) in cattle slaughtered at Bako municipal abattoir was conducted from November 2011 to April 2012. Out of 246 cattle examined, 29 (11.88%) were found to harbor visible hydatid cysts. Significantly higher infection was detected in cattle's with poor body conditions (P<0.05) than animals with medium and good body condition score. No significant variation was observed with regard to sex of animals. Regarding organ distribution, infections of the lung, liver, kidney, and spleen and heart were 47.2%, 38.88%, 8.33%, and 2.77% respectively. Of the total 36 hydatid cysts counted, 17(47%), 14 (38.88%), and 5 (13.88%) were found to be small-sized, medium-sized, and large-sized, respectively. Likewise, out of 36 cysts assessed, 18 (50%) were fertile, 4 (11.11%) sterile, and 14 (38.88%) calcified. Of the 29 fertile cysts subjected for viability test, 12 (27.77%) were viable while 8 (22.22%) were nonviable. Moreover, assessment of annual economic loss due to bovine hydatidosis at Bako municipal abattoir from offal condemnation and carcass weight loss was estimated at 180,792 ETB (Ethiopian Birr). Despite the moderate magnitude of infection detected currently, there seems to be an existing socioeconomic situation favorable for hydatidosis, and hence, it remains one of the most important diseases warranting serious attention for prevention and control actions in Bako district. Hence, establishment of well-equipped standardized abattoirs, creation of public awareness, and control of stray dogs are of paramount importance.

Knowledge and perception of community about causes of cattle abortion and case‐control study of brucellosis as cause of abortion in Jimma zone, Ethiopia

“…This may indicate that farmers in the study areas keep cattle mainly for milk production and heifers were used for replacement purposes. A similar finding was reported by (Berihu & Toffik, 2014;Mengistu et al, 2017) where heifer and cows dominate their herd composition followed by oxen. The oxen were important for plowing land for crop cultivation and also for threshing.…”

Prevalence, Fertility, and Viability of Cystic Echinococcosis in Cattle Slaughtered at Adaba Abattoir, West Arsi Zone, Ethiopia

“…However, male animals were more affected than females. This observation is similar to the findings of studies conducted in Bako abattoir (26) and Debre Tabor abattoir (31). This may be due to the small number of female animals slaughtered at the abattoir during the study period.…”

“…The infection rate found in the present study is lower when compared with studies conducted in Shashamanne abattoir (49.5%) (25) and Jimma abattoir (54.5%) (16). However, it is higher compared to the reports of studies conducted in Bako abattoir (11.8%) (26) and Gondar Elfora export abattoir (20.5%) (27). The differences in the prevalence of cystic echinococcosis among cattle in different areas of Ethiopia could be due to a range of factors, including agroecology, public awareness, and culture and religion of the society.…”

“…This is summation of the carcass weight loss and loss due to organ condemnation. But these losses and infection prevalence do not show the real estimates because these estimates are made by meat inspection in abattoirs only and many animals slaughtered at backyard are not been included (Tadesse [42]) [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65].…”
