Occurrence and financial effect of ovine and bovine liver condemnations due to abscesses and necrosis in the Sudan

الملخص EN

Livers are known to be of high nutritional value.

They are eaten raw as a food habit in the Sudan.

Surveys regarding liver abscesses and necrosis in ovine and bovine livers were carried out to reflect their magnitude as liver affections and their economic effect.

Retrospective studies of liver condemnation of slaughtered animals in Omdurman Central Abattoir were carried out at different periods during 1994 and 1995 and for the whole seven years from 1996 to 2002 in Elsabalouga Abattoir.

Monthly records in the latter years were used to study the effect of season on liver condemnation.

Liver condemnations due to different affections in slaughtered sheep and cattle during the period 1994-1995 were found to be 26.2 % and 5.4 % respectively.

Out of those condemnations 57.6 % and 22 % respectively were found to be due to abscesses and necrosis.

The surveillance of the liver condemnation in Elsabalouga Abattoir, during the period 1996-2002, revealed 77.43 % condemned livers due to abscesses and necrosis out of the total condemned livers that in turn constituted15.45 % of the examined ovine livers.

Out of 10.69 % of the bovine condemned livers due to different affections, 11.96 % were condemned due to abscesses and necrosis.

There was strong to moderate correlation between the total condemned ovine and bovine livers and the condemnation due to abscesses and necrosis.

Seasons were found to be of no significant effect on the ovine and bovine liver condemnations.
