Effects of exogenous fibrolytic enzymes on the ruminal fermentation of agro-industrial by-products

South African Journal of Animal Science, 2019
This research was performed to evaluate the effects of increasing doses of exogenous fibrolytic enzymes (EFE), namely at 0 (control), 1 (low), 2 (medium) and 4 (high) μL/g dry matter (DM), on the ruminal fermentation of low-quality agro-industrial by-products, grape pomace, almond hull and pomegranate peel.

Recycling Agricultural Waste: Sustainable Solutions for Enhancing Livestock Nutrition

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
The increasing demand for sustainable agricultural practices prompts a reevaluation of feeding strategies in ruminant nutrition. Agricultural waste, often viewed as a by‐product, presents a promising opportunity to enhance the sustainability of livestock production systems.

Digestion and microbial protein synthesis in sheep as affected by exogenous fibrolytic enzymes

South African Journal of Animal Science, 2012
The aim of the study was to determine the effect of an exogenous fibrolytic enzyme (EFE) on the ruminal disappearance of dry matter (DM), neutral detergent fibre (NDF), crude protein (CP) and on the microbial protein synthesis (MPS) in sheep of a milled substrate consisting of a 50 : 50 mixture of lucerne hay (LH) and wheat straw (WS).

Effect of Fibrolytic Enzymes and Regrowth Ages on Fermentation Profile and Nutrient Composition of Mombasa Grass and Elephant Grass Silages

Grass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Two experiments were carried out to evaluate whether the addition of cellulase and/or xylanase enzymes interacts with regrowth age (RA) in mombasa grass (Megathyrsus maximus) and elephant grass cv. BRS Capiaçu (Cenchrus purpureus) to alter nutritive composition and fermentation profile. Mombasa and elephant grass plots were mowed and harvested

A review on Effects of Exogenous Fibrolytic Enzymes in Ruminant Nutrition

, 2019
Ruminant can convert plant biomass that human can’t use directly to high quality protein-meat and milk, which is important to agriculture and human society. However, the conversion efficiency is dependent on digestibility of plant cell walls. The conversion efficiency is low as well as the digestibility of plant material at present.

Effects of exogenous fibrolytic and amylolytic enzymes on ruminal fermentation and performance of mid-lactation dairy cows [PDF]

Journal of Dairy Science, 2019
Lactation diets are composed mostly of carbohydrates that are not fully fermented by rumen microbes. The aim of this study was to evaluate exogenous fibrolytic (Fibrozyme, Alltech Inc., Nicholasville, KY) and amylolytic (Amaize, Alltech Inc.) enzymes on nutrient intake, sorting index, total-tract apparent digestibility, ruminal fermentation, nitrogen ...

Effect of exogenous fibrolytic enzymes in total mixed ration on milk yield, composition, feed efficiency in Holstein Friesian crossbred cows

Indian Journal of Animal Sciences, 2019
An experiment was conducted to evaluate the effect of exogenous fibrolytic enzymes (EFE; 800 IU/g endo 1,4- β glucanase, 700 IU/g 1 (3),4-β glucanase and 2700 IU/g endo 1,4-β xylanase) @ 240 mg/kg total mixed ration (TMR) feeding on milk and ...

Influence of exogenous fibrolytic enzymes and fumarate on methane production, microbial growth and fermentation in Rusitec fermenters [PDF]

British Journal of Nutrition, 2007
Two incubation runs were conducted with Rusitec fermenters to investigate the effects of three additive treatments (mixed fibrolytic enzymes from Trichoderma longibrachiatum (FE), disodium fumarate (FUM) and both additives (MIX)) on rumen microbial growth and fermentation of a grass hay:concentrate (600 : 400 g/kg DM) substrate. Each fermenter received
