This experiment was carried out to study the effect of a directly fed exogenous fibrolytic enzyme on intake and digestion of DM, OM, protein, NDF, ADF, and hemicellulose of alfalfa and ryegrass hay by sheep. Four diets were randomly assigned to four ruminally cannulated lambs using a 4 x 4 Latin square design, repeated in time, with a factorial arrangement (2 x 2) of diets: 1) alfalfa hay; 2) a...

BACKGROUND AND OBJECTIVES Essential oils may improve the utilization of nutrients by ruminal microorganisms. The aim of this study was to assess the effect of different doses of ajowan essential oils (AEO) on growth and fibrolytic activity of anaerobic fungi, and generic distribution of ciliated protozoa (in vitro). MATERIAL AND METHODS Different doses of AEO (0, 150, 300, 450 and 600 ppm) we...

This study was done to determine the effectiveness of supplementary enzymes at increasing the fiber digestion by ruminal microorganisms and to assess whether enzyme activity limits the rate of fiber digestion in ruminal digesta. In vitro comparisons of enzyme activities in two feed enzyme preparations (A and B) with enzyme activities extracted from ruminal fluid indicated that the addition of f...

Here, we report the draft genome sequence of a fibrolytic bacterium, Clostridium straminisolvens JCM 21531(T), isolated from a cellulose-degrading bacterial community. The genome information of this strain will be useful for studies on the degradation enzymes and functional interactions with other members in the community.

Fibrolytic enzymes and bypass methionine were fed in molasses slurries in an evaluation of growing cattle performance. Eight fibrolytic enzyme treatments were offered and consisted of control (molasses only), 1.5 or 3.0 g/hd/ d of Cattle-aseTM “HR” (C1X and C2X), 0.12 g/hd/d of LodestarTM Biocellulase A20 (A20), 0.12 g/hd/d LodestarTM Biocellulase A20 and 0.06 g/hd/d LodestarTM Biocellulase X20...

Dairy production system in developing countries mainly depends on forage plants and crop residues as major portion of the Ruminants diet. The majority dry matter crops is made up fibre whose digestibility limited rumen ecosystem. Use exogenous fibrolytic enzymes (EFE) gaining popularity recent days they overcome limitations other methodologies which are used to improve fibre. Due microbial enzy...
