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 کاملDistribution of current photosynthate in two Guinea grass (Panicum maximum Jacq.) cultivars.
In a glasshouse experiment, different tiller categories (main, young primary, and old primary) of two Guinea grass cultivars, Mombaça and Tanzânia, were (14)C-labelled to investigate C translocation between tillers. In both cultivars, young primary tillers retained less radiocarbon (79%) than main (86%) and old primary (87%) labelled tillers, suggesting that the photosynthetic capacity of the y...
متن کاملEffect of exogenous fibrolytic enzyme on ruminal fermentation and digestibility of alfalfa and rye-grass hay fed to lambs.
This experiment was carried out to study the effect of a directly fed exogenous fibrolytic enzyme on intake and digestion of DM, OM, protein, NDF, ADF, and hemicellulose of alfalfa and ryegrass hay by sheep. Four diets were randomly assigned to four ruminally cannulated lambs using a 4 x 4 Latin square design, repeated in time, with a factorial arrangement (2 x 2) of diets: 1) alfalfa hay; 2) a...
متن کاملEffect of Applying Ammonia or Fibrolytic Enzymes to Bermudagrass Hay on Feed Intake, Digestibility, and Growth of Beef Steers
This study evaluated the effects of the method of applying a commercial fibrolytic enzyme, Biocellulase A20 (A20), or ammonia to bermudagrass hay on the feed intake, digestibility, and growth performance of 50 AngusBrangus steers. Five-week fall regrowth of bermudagrass was harvested and treated with either anhydrous ammonia or A20 at rates of 3% dry matter (DM) and 15 g/ton of hay, respectivel...
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...
