Abomasal Coccidiosis Associated with Proliferative Abomasitis in a Sheep

Prevalence and Pathology of Abomasal Abnormalities in Sheep in Southern Iran

Abomasal abnormalities impose economic constraints on sheep production, most of which are subclinical and cannot be easily detected by routine clinical examination. In this survey, morphopathological lesions of 100 abomasa of sheep slaughtered in Fars Province, southern Iran were studied from spring to autumn of 2011. Grossly, raised pale to whitish nodular areas to irregularly thickened mucosa...

Eosinophilic myositis Associated with Sarcocystis in Sheep

Effect of protein on abomasal secretion of acid in sheep.

1. The relationship between protein content of abomasal digesta and abomasal secretion of acid was studied in sheep fitted with re-entrant cannulas in the proximal duodenum. 2. A close relationship was found between the rate of passage of protein through the abomasum and acid secretion, both after varying the protein content of the rations supplied, and after direct introduction of proteins int...

An Overview of Intestinal Coccidiosis in Sheep and Goats

Coccidial infection is universal in sheep and goats, and coccidiosis can be a significant problem in the young of both species. The coccidian are members of the protistan phylum Apicomplexa, subclass Coccidiasina, intracellular parasites, characterized at some stage of the life cycle by a typical apical complex of organelles at one end of the organism. Members of the genus Eimeria and Isospora ...

Laboratory findings associated with abomasal ulcers/tympany in range calves.

The etiology of abomasal ulcers/tympany was investigated in 48 animals from 36 ranches in Wyoming and Nebraska. Results indicate that subclinical trace mineral deficiencies of copper and/or selenium exist in the range cattle in west central Nebraska and Wyoming. Etiological agents most frequently incriminated by bacteriologic cultures and/or histopathic examination were Clostridium perfringens ...
