In 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 کاملInfluence of Fibrolytic Enzymes on the in vitro Hydrolysis and Fermentation of Different Types of Roughages Treatment
The effects of pre-treating different types of roughages with alkali on the efficacy of exogenous fibrolytic enzymes for improving their digestibility were studied in vitroin factorial arrangement 4 × 3 × 5 (enzyme, treatment and roughage types). Two fibrolytic feed enzymes novozyme (N) and celloclast (C) their combination (N+C) were evaluated for their potential to improve in vitrodegradation ...
متن کاملUse of exogenous fibrolytic enzymes to enhance in vitro fermentation of alfalfa hay and corn silage.
Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with...

متن کاملEffects of Feeding Fats on Rumen Fermentation and Milk Composition
Milk yields of high-producing dairy cattle demand that energy intake be maximized. Energy intake is not only important during the period of peak milk production but also must be sufficient to maintain persistency of production and support body weight gain following peak milk yield. To increase ration energy density, cereal grains are used to replace forages, but this practice is limited since a...
