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 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...
متن کاملThe role of exogenous enzymes in promoting growth and improving nutrient digestibility in poultry
The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...
