Effect of Monensin on Ciliate Protozoa in Rumen of Sheep Fed an Oaten Chaff Diet
Field studies of grazing lambs without protozoa in the rumen indicated that live weight gains were 15% higher than in faunated lambs (Bird &nd Leng 1985). Poos et al. (1979) reported that monensin decreased protozoa1 populations in the rumen but Leng et al. (1984) found no effect of monensin on half life or growth rate of protozoa. However in previous studies (Habib, G. & Preston, T.R. 1984 unp...
متن کاملMonensin and protein supplements on methane production and rumen protozoa in bovine fed low quality forage
This study aimed at evaluating the effect of sodium monensin and protein supplementation in the enteric methane production and the population of ruminal protozoa in bovine fed Brachiaria brizantha Marandu cultivar hay. The treatments were: mineralized salt, mineralized salt with monensin, proteinenriched salt and protein-enriched salt with monensin. The experimental outline was in a 4 x 4 Latin...

متن کاملProtease activities of rumen protozoa.
Intact, metabolically active rumen protozoa prepared by gravity sedimentation and washing in a mineral solution at 10 to 15 degrees C had comparatively low proteolytic activity on azocasein and low endogenous proteolytic activity. Protozoa washed in 0.1 M potassium phosphate buffer (pH 6.8) at 4 degrees C and stored on ice autolysed when they were warmed to 39 degrees C. They also exhibited low...
متن کاملRumen Protozoa - Potential for Manipulation
The manipulation of rumen function through the removal of the ciliate protozoa has not resulted in consistent changes in ruminant production. Current research findings are discussed with particular emphasis given to the role of protozoa in fibre digestion in the rumen and the availability of protein for intestinal digestion. Dietary conditions under which positive responses to defaunation can b...
