15 صفحه اولFibrolytic activities and cellulolytic bacterial community structure in the solid and liquid phases of rumen contents.
Four sheep were fed an alfalfa hay diet. Rumen content samples were collected three hours after feeding in order to total microorganism population (TP), solid attached population (SAP) and solid attached firmly population (SAFP). Fibrolytic specific activities (xylanase, CMCase and beta-glycosidases) were estimated by the amount of reducing sugars or p-nitrophenol released from the appropriate ...
متن کاملEffect of Fibrolytic Enzyme on Nutrient Utilization and Rumen Fermentation Pattern in Sheep
Effect of fibrolytic enzyme supplementation on nutrients utilization of sheep was studied. Twelve male Patanwadi sheep (12-15 month) were randomly divided in two groups of 6 each. Sheep were fed rations containing 50 % wheat straw and 50% compound concentrate mixture. A fibrolytic exogenous enzyme @ 0.025% was added to the ration of animal fed TMR. At the end of 14 weeks experimental period, an...
متن کاملIn vitro Effects of Exogenous Fibrolytic Enzymes on Rumen Fermentation of Wild Guinea Grass (Panicum maximum)
This study aimed to evaluate the potential of commercial enzymes cellulase (CE), xylanase (XY) and the combination of CE + XY to improve rumen fermentation of Guinea grass ecotype ‘A’ (Panicum maximum). The experiment was carried out in a randomized complete block design. In vitro incubations were performed with four doses of individual enzymes and their combinations (1:1 from each enzyme) as 5...
متن کاملCereal supplementation modified the fibrolytic activity but not the structure of the cellulolytic bacterial community associated with rumen solid digesta.
4 ruminally cannulated cows were fed a forage diet (93% hay + 7% straw) and a mixed diet (33 % hay + 7% straw + 40% barley) in a 2 x 2 crossover experimental design. In sacco degradation of forage, fibrolytic activities (polysaccharidases and glycosidases) of the solid-associated bacteria (SAB), and distribution of the 3 main cellulolytic bacterial species (Fibrobacter succinogenes, Ruminococcu...
