the effect of three levels of eucalyptus leaf (0, 28.65 or 57.37mg/200mg substrate), which were either oven, freeze or air dried on in vitro ruminal fermentation characteristics was assessed. the studied parameters were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability, partitioning factor (pf) (ratio of substrate truly degr...

in this trial, the effect of different levels of echum amoneum (ea) (0.3, 30, 300 or 3000 µl) on in vitro ruminal fermentation characteristics and methane production was assessed. the parameters studied were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability (ivomde), partitioning factor (pf) (the ratio of substrate truly deg...

This work aimed to optimize the parameters affecting partitioning of a bacteriocin-like inhibitory substances (BLIS) from Lactococcus lactis Gh1 in extractive fermentation using polyethylene glycol (PEG)/dextran aqueous two-phase system (ATPS). was developed for simultaneous cell cultivation and downstream processing BLIS. Results showed that molecular weight PEG, PEG concentration, dextran T50...

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

Two trials were conducted to investigate the effects of disodium fumarate (DSF; 0.00, 8.00, 10.00 and 12.00 mM) and thyme essential oil (TEO; 0.00, 100.00, 200.00, 300.00 and 400.00 µL L-1) solely and simultaneously (10.00 mM DSF along with 100.00, 200.00, 300.00 and 400 µL L-1 TEO) on in vitro ruminal fermentation of a 50:50 alfalfa hay to concentrate diet. The D...

This study aimed to identify chemical composition of Thymus kotschyanus essential oil (TKEO) and to evaluate the effects of different doses of TKEO on in vitro gas production, fermentation parameters, acidosis and protozoal population using a completely randomized design with four replicates. Two diets (D1: 100% forage and D2: 30% forage+70% concentrate) were incubated with buffered rumen fluid...

In this paper, we propose an efficient hybrid Particle Filter (PF) algorithm for video tracking by employing a genetic algorithm to solve the sample impoverishment problem. In the presented method, the object to be tracked is selected by a rectangular window inside which a few numbers of particles are scattered. The particles’ weights are calculated based on the similarity between feature vecto...

the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...

The present experiment was conducted to study the effect of sodium bentonite (SB) in ameliorating adverseeffects aflatoxin on vitro rumen fermentation wheat straw. Five treatment groups, viz. T1: control (wheatstraw); T2: T1 + 300 ppb B1 (AFB1); T3: T2 0.33% SB; T4: 0.5% SB and T5: 1.0% wereprepared incubated vitro. Truly degradable dry matter (TDDM), truly organic (TDOM),gas production (GP), m...
