This study aims to increase the in vitro ruminal degradability of oil palm fronds (OPFs) through enzymatic pretreatment. The isolated fungi were selected based on their lignocellulosic degrading enzyme activities. Eleven successfully isolated, and activities evaluated. Three fungi, F1, F2 F4 selected, they identified as Trichoderma harzianum MK027305, MK027306 Fusarium solani MK027309, respecti...

resistance of microencapsulated fish oil (mfo) in the rumen and its effects on fermentability of nutrients in the rumen was studied in 3 experiments. the key parameter in these studies was the amount of oil released from the microcapsules and their effects on gas production and rumen degradability in comparison with unprotected fish oil (fo). in the first experiment the effect of rumen and abom...

The objectives of this study were to determine the molecular weight of condensed tannins (CT) extracted from mangosteen (Garcinia mangostana L) peel, its protein binding affinity and effects on fermentation parameters including total gas, methane (CH4) and volatile fatty acids (VFA) production. The average molecular weight (Mw) of the purified CT was 2,081 Da with a protein binding affinity of ...

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...

this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Seven birdsfoot trefoil (BFT) varieties (Lotus corniculatus) grown in Sweden, were harvested at the 50% ̄owering stage and analysed for tannins by the radial diffusion and HCl±butanol methods. The ̄avan-3-ol composition of different BFT tannins was determined by HPLC. Tannins were isolated and examined for their molecular weight distributions by HPLC gel permeation chromatography (GPC) and MALD...

This study determined the effect of pelagic Sargassum on in vitro dry matter and organic degradation, total gas production (TGP), protozoa population. The treatments were different levels inclusion a basal substrate (Stargrass hay; Cynodon nlemfuensis) as follows: T0 (control treatment based Stargrass hay), T10 (90% hay + 10% Sargassum), T20 (80% 20% T30 (70% 30% Sargassum). Ruminal fermentatio...
