Rumen fermentation pattern of sheep is greatly affected by several factors. This research studied the effect of field and experimentally-induced cases of frothy bloat on physical examination, blood constituents and rumen fermentation efficiency in Baladi Egyptian sheep. Sixty-six native breed Baladi Egyptian sheep were classified according to clinical presentation into fifty-eight apparently healthy sheep and eight clinically diseased cases of frothy bloat divided into three field cases due to grazing on lush pasture of barseem and five experimental cases induced by ingestion of cabbage leaves. All animals were subjected to detailed case history, comprehensive clinical examination and sampling of blood and rumen liquor for analysis. Results revealed that field and experimentally-induced cases of rumen frothy bloat caused highly significant increase in pulse and respiratory rates with highly significant decrease in rumen motility. Field cases of frothy bloat caused highly significant increase in Holotricha % and monocytes % with highly significant decrease in TPC, Entodinium %, TVFAs, lactic acid, propionic acid, butyric acid, acetic acid, CH4, lymphocytes %, albumin and A/G ratio. Experimentally-induced cases of frothy bloat caused highly significant increase in Hb and MCHC with highly significant decrease in TVFAs, lactic, butyric and acetic acids, A/P ratio, CH4 and CH4/TVFAs %. It could be concluded that barseem lush-pasture bloat has more dramatic effect on rumen fermentation efficiency than bloat due to ingestion of cabbage leaves. Frothy bloat is still field problem of concern despite awareness of sheep farmers. Further investigations are highly recommended from aspects of rumen methane, rumen enzymes and rumen ciliates for therapeutic and productive purposes
