Abstract
Ovine lipomatosis was observed in a herd of native breed of sheep. The herd was raised in area adjacent to the desert and kept for milk production, while rams used for fattening purpose on the other hand, the herd also used for wool production. The owner paid our attention that the herd showed clinical signs in the form expressed by emaciation, loss of body condition, drop of milk yield from lactating ewes, and reproductive imperformance. Tracing the history of the herd, animals raised and kept on the rest of different typed of maise, wheat and growing grass. While, drinking water was artisan water. Selected cases of the herd were used for further biochemical analysis of some indices reflecting the fat metabolism on the other hand some cases were slaughtered for post-mortem changes. Biochemical indices included total lipids, Triglycerides phospholipids and serum selenium. Postmortem findings showed massive amount of omental adipose tissues with lumpish lesions, and massive fat depot showing lumpish lesion of calcification in mesenteric fat too. Biochemical analysis indicated that there is a marked changes in total lipidis triglycerides, phospholipids and selenium.
Highlights
Abdominal fat necrosis is generally characterized by the presence of hard irregular masses of necrotic fat tissue in the mesentery perirenal fat and intestine, a myriad of terms has been applied for this syndrome in duding multiple (Carrol & Richard, 1958) lipomatus tumour (Edigson, 1952), lipofibromatosis (Moon 1954), Fettgewbsnekrose (Dirksen, 1965) and abdominal necrosis (Williams et al, 1969, El-Sebaie et al, 1985; El-Sebaie and Hofmann, 1992)
The above mentioned researches are reffered to bovine fat necrosis but there is no evidence or researches did not mentioned about the occurrence of fat necrosis in small ruminants sheep or goats, whilst the clinical picture of bovine fat necrosis are well recognized, the disease in sheep and goats is for first time diagnosed in sheep herd in Egypt
Histopathology: Fat necrosis was markedly seen in the adipose tissue indicated by appearance of feather like crystals
Summary
Abdominal fat necrosis (lipomatosis) is generally characterized by the presence of hard irregular masses of necrotic fat tissue in the mesentery perirenal fat and intestine, a myriad of terms has been applied for this syndrome in duding multiple (Carrol & Richard, 1958) lipomatus tumour (Edigson, 1952), lipofibromatosis (Moon 1954), Fettgewbsnekrose (Dirksen, 1965) and abdominal necrosis (Williams et al, 1969, El-Sebaie et al, 1985; El-Sebaie and Hofmann, 1992). Blood samples were collected by means of vein puncture, serum samples were separated and used for biochemical essay. Lipogram indices were determined including total lipids, triglycerides, and phospholipids, using Byeunicum spectrophotomer and biochemical diagnosis kits.
