A 6-year survey of pathological conditions of slaughtered animals at Zango abattoir in Zaria, Kaduna State, Nigeria.
A 6-year retrospective study (2000-2005) of animals slaughtered at the Zango abattoir in Zaria, Kaduna State, Nigeria was carried out to determine disease conditions encountered in slaughtered animals. Records kept at the abattoir were analysed. A total of 69,307 cattle, 3,820 goats and 1,763 sheep were slaughtered for the period under study. Of the 69,307 cattle slaughtered for the period, 22,459 (32.41%) were males and 46,848 (67.59%) were females, while 1,763 sheep were slaughtered comprising of 506 (28.70%) males and 1,257 (71.30%) females, and 3,820 goats made up of 1,212 (31.73%) males and 2,608 (68.27%) were females. The major disease and/or pathological conditions were helminthosis (fascioliasis, haemonchosis and paramphistomosis) 16.20%, Streptothricosis 4.15%, Pericarditis 2.20%, liver cirrhosis 2.08%, abscesses 1.04%, pneumonia 0.14%, nephritis 0.05% and Contagious Bovine Pleuropneumonia, Tuberculosis and Nocardiosis 0.01% each. Out of the 15,075 infected organs, 13,314 (88.38%) were partially salvaged while 1,751 (11.6%) whole organs were condemned. A total of 1,239 pregnant cows, 221 pregnant ewes and 637 pregnant does were slaughtered, representing a foetal wastage of 2.65% for cattle, 17.58% for sheep and 24.43% for goats. The result of this study apart from serving as an indicator of field disease condition also demonstrates cases of serious losses in production due to slaughter of pregnant animals especially for sheep and goats.
