Role of exogenous fibrolytic enzymes in ruminant feeding

The Indian Journal of Animal Sciences, 2014
The complex crop residues and straws are main feed resource available for feeding livestock in developing countries like India. These straws mainly consist of ligno-cellulose complex, which is not very easily and fully digested. Several attempts were tried to address the issue but met with varying degree of success.

A Comparison of Methods of Adding Fibrolytic Enzymes to Lactating Cow Diets

Journal of Dairy Science, 2000
Holstein cows (n = 43) in early lactation were used to investigate effects of method of adding fibrolytic enzymes to diets on feed intake, milk production, and digestibility. Cows were blocked according to parity and calving date and randomly assigned to three treatments: control, enzymes applied to the total mixed ration (E-TMR), or enzymes added to ...

Exogenous fibrolytic and amylolytic enzymes at feeding dairy cows [PDF]

, 2018
As dietas de vacas em lactação são compostas principalmente por carboidratos que não estão totalmente disponíveis para fermentação microbiana no rúmen, o que pode ser um fator crítico para a obtenção de energia em ruminantes.

Seasonality of fibrolytic enzyme activity in herbivore microbial ecosystems

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012
Fibre (cellulose, hemicellulose and lignin) is the most abundant polysaccharide in nature and is hydrolysed by gut micro-organisms of herbivores because they can produce a set of extracellular enzymes. This study examined seasonal changes in the fibrolytic enzyme activity of microbial ecosystems of five herbivores (buffalo, cow, impala, wildebeest and ...

The effects of exogenous fibrolytic enzymes on the in vitro release of xylooligosaccharides and monosaccharides varies across six varieties of wheat [PDF]

, 2023
Wheat is a widely used cereal grain for pig and poultry feeds globally. Despite this, there are noticeable differences in its nutritive value, potentially due to varying characteristics like inherent non-starch polysaccharide (NSP) content and ...

Influence of fibrolytic enzymes on ruminal disappearance and fermentation in steers fed diets with short and long particle length of forage

Italian Journal of Animal Science, 2010
The effects of an exogenous fibrolytic enzyme mixture on in sacco ruminal disappearance and fermentation of growing (380 kg body weight) and finishing (440 kg body weight) steers fed with diets to short (10 mm) and long (50 mm) particle length (PL) were ...

Limits of Exogenous Fibrolytic Enzymes to Improve Digestion and Intake of a Tropical Grass

Asian-Australasian Journal of Animal Sciences, 2007
The effect of the addition of exogenous fibrolytic enzymes (mainly xylanase and cellulase activities, 15 ml/15 kg of fresh forage), on intake, total tract digestibility and nylon bag degradability of a chopped fresh Digitaria decumbens grass was studied at 2 stages of regrowth ( 21 and 56-day old grasses).

Effect of Direct-Fed Fibrolytic Enzymes on the Lactational Performance of Dairy Cows

Journal of Dairy Science, 1999
In trial 1, 30 midlactation (213 d in milk) Holstein cows were randomly assigned to a control or enzyme treatment in a two-period crossover design and were fed a total mixed ration based on alfalfa hay and silage. Cows on the enzyme treatment received an enzyme solution containing cellulases and xylanases, which was sprayed on the forage component of ...

, 2009
The objective was to determine the effects of an exogenous fibrolytic enzyme mixture (enzyme) on intake, digestion and ruminal fermentation of Guinea grass (Panicum maximum var.

Effects of a combination of fibrolytic and amylolytic enzymes on ruminal enzyme activities, bacterial diversity, blood profile and milk production in dairy cows

Animal, 2022
We hypothesised that adding a combination of fibrolytic and amylolytic enzymes to the diet of early-lactation dairy cows would improve rumen enzyme activity and bacterial diversity, promote energy metabolism, and benefit milk production in cows.
