The objectives were to compare the effect of exogenous fibrolytic enzyme (Biocellulase A20) or anhydrous ammonia (4% DM) treatment on the nutritive value, voluntary intake, and digestion kinetics of bermudagrass (Cynodon dactylon cultivar Coastal) hay harvested after 2 maturities (5- and 13-wk regrowths). Six individually housed, ruminally cannulated Brangus steers (BW 325 ± 10 kg) were used in an experiment with a 6 × 6 Latin square design with a 3 (additives) × 2 (maturities) factorial…

Screening exogenous fibrolytic enzyme preparations for improved in vitro digestibility of bermudagrass haylage.
TLDR
Several EFE were identified that increased the NDFD and in vitro fermentation of 4-wk BH and revealed why some EFE are more effective than others.
Effect of the dose of exogenous fibrolytic enzyme preparations on preingestive fiber hydrolysis, ruminal fermentation, and in vitro digestibility of bermudagrass haylage.
TLDR
Application of increasing doses of the E FE increased NDF hydrolysis, NDFD, and ruminal fluid fermentation of bermudagrass haylage, but the optimal dose varied with the EFE.
Improving the performance of dairy cattle with a xylanase-rich exogenous enzyme preparation.
TLDR
Examination of effects of adding 2 exogenous fibrolytic enzymes (EFE) to the total mixed ration (TMR) on the performance of lactating dairy cows and the kinetics of ruminal degradation of the diet suggested that this EFE could be used to increase theperformance of lactates dairy cows fed diets containing up to 10% bermudagrass.
Effects of bismuth subsalicylate and encapsulated calcium-ammonium nitrate on ruminal fermentation of beef cattle.
A replicated 5 × 5 Latin square design with a 2 × 2 + 1 factorial arrangement of treatments was used to determine the effects of bismuth subsalicylate (BSS) and encapsulated calcium-ammonium nitrate…
Effects of fibrolytic enzymes and isobutyrate on ruminal fermentation, microbial enzyme activity and cellulolytic bacteria in pre- and post-weaning dairy calves
The objective of the present study was to evaluate the effects of fibrolytic enzymes (FE, containing 160 units of cellulase and 4000 units of xylanase) or isobutyrate (IB) supplementation on ruminal…
Chemical and biological treatment of cotton gin trash for fattening Santa Ines lambs
Ruminant Nutrition Symposium: Improving cell wall digestion and animal performance with fibrolytic enzymes.
This paper aimed to summarize published responses to treatment of cattle diets with exogenous fibrolytic enzymes (EFE), to discuss reasons for variable EFE efficacy in animal trials, to recommend…
Using phosphorylated mannan oligosaccharide and fibrolytic enzyme as natural feed additive substitutes for growth-enhancing technologies in sustainable beef production.
TLDR
The NFA were less profitable during backgrounding, but not profitable for finishing, and the C treatment ADG was greater than the MOS, FIB, and MOS+FIB for finishing.
Evaluation of cellulolytic exogenous enzyme-containing microbial inoculants as feed additives for ruminant rations composed of low-quality roughage
Abstract The supplementation of ruminant diets with exogenous cellulolytic enzymes can improve their digestibility and feeding value. The objective of this study was to determine the effect of…
Laboratory silo type and inoculation effects on nutritional composition, fermentation, and bacterial and fungal communities of oat silage.
TLDR
The use of inoculant improved oat silage quality partially by a shift in the bacterial community composition during ensiling, which mainly consisted of an increased relative abundance of Lactobacillaceae and reduction of Leuconostocaceae relative to CON.

Effect of method of applying fibrolytic enzymes or ammonia to Bermudagrass hay on feed intake, digestion, and growth of beef steers.
TLDR
Application at cutting was the most promising method of enzyme treatment, and this treatment was almost as effective as ammonia for enhancing forage quality.
Effects of treatment with ammonia or fibrolytic enzymes on chemical composition and ruminal degradability of hays produced from tropical grasses
Effect of direct-fed fibrolytic enzymes on the digestive characteristics of a forage-based diet fed to beef steers.
TLDR
Results from this study indicate that direct application of enzymes to forages is capable of improving forage digestion.
Effect of fibrolytic enzymes on the fermentation characteristics, aerobic stability, and digestibility of bermudagrass silage.
TLDR
Results show that when applied at ensiling, certain fibrolytic enzymes (particularly Promote) can improve the digestibility, fermentation, and aerobic stability of bermudagrass silage.
Effect of exogenous enzymes on digestibility of barley silage and growth performance of feedlot cattle
TLDR
Barley silage was sprayed with water or with a 2:1 combination of commercial cellulase and xylanase preparations, or the enzymes were introduced directly into the rumen, in a digestibility study using 10 sheep to study apparent digestibilities of dry matter and neutral detergent fibre.
Effects of increasing levels of corn distillers dried grains with solubles to steers offered moderate-quality forage.
TLDR
Feeding 0.3% up to 1.2% of BW daily of DDGS as a supplement to forage-based diets resulted in no adverse effects on forage digestion or fermentation and resulted in increased nutrient supply in steers fed moderate-quality smooth brome hay.
Effect of fibrolytic enzyme application to low- and high-concentrate diets on the performance of lactating dairy cattle.
TLDR
This fibrolytic enzyme increased the digestibility of DM, CP, neutral detergent fiber, and acid detergent Fiber and the efficiency of milk production by dairy cows and resulted in as much milk production as that from cows fed the untreated high-concentrate diet.
Improving Forage Quality and Animal Performance with Fibrolytic Enzymes
TLDR
The intention in this paper is to review the literature on the effects of enzyme application to feeds at ensiling or feeding, and to present the results of certain preliminary studies aimed at improving the utilization of tropical forages with fibrolytic enzymes.

Effect of alkali pretreatment of wheat straw on the efficacy of exogenous fibrolytic enzymes.
TLDR
Pretreatment of straw with alkali enhanced the efficacy of exogenous enzymes, presumably by breaking esterified bonds and releasing phenolic compounds and/or by swelling the crystalline cellulose and enhancing enzyme penetration.
