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 کاملMetagenomic Insights into the Fibrolytic Microbiome in Yak Rumen
The rumen hosts one of the most efficient microbial systems for degrading plant cell walls, yet the predominant cellulolytic proteins and fibrolytic mechanism(s) remain elusive. Here we investigated the cellulolytic microbiome of the yak rumen by using a combination of metagenome-based and bacterial artificial chromosome (BAC)-based functional screening approaches. Totally 223 fibrolytic BAC cl...
متن کاملinvestigation of methods of extraction, concentration and conservation of rumen content fibrolytic enzymes
this study was carried out to determine the potential of rumen microorganisms in samples taken from slaughterhouse to produce fibrolytic enzymes and to compare different methods for extraction, concentration and conservation of them. according to the results, the average specific activity of cellulase and xylanase were 7.5 and 16.5 u/mg protein respectively. the application of homogenizing and...
متن کاملPerformance of Lactating Dairy Cows Fed Yeast and Fibrolytic Enzymes
We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture of Saccharomyces cerevisiae) and various amounts of FP800 (a fibrolytic enzyme mixture) on lactation performance. Treatments were arranged in a 4 × 2 factorial design consisting ...
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...
