The chemical composition and digestibility of twelve plant samples (Arthrocnemum macrostachyum, Atriplex canescens, Artemesia herba-alba, Astragalus gombo, Calobota saharae Ceratonia siliqua, Gleditsia triacanthos, Hedysarum coronarium, Medicago sativa, Ononis natrix L, Hordeum vulgare and <...

160 ABSTRACT: The in vitro gas production of some semi-arid browse species were evaluated. The relationship between in vitro gas measured on incubation of tannin-containing browses in buffered rumen fluid and calculated from short chain fatty acid (SCFA) production was investigated. Crude protein (CP) contents in the browses ranged from 13.85 to 16.65% dry matter (DM). The NDF, ADF and ADL were...

In vitro gas production techniques simulate the rumen fermentation process and they have been used to evaluate the potential of feeds to supply nutrients to ruminants. Thus, effects of various levels of cobalt supplementation on gas production and rumen fermentation were investigated using an in vitro gas production technique. Ground samples (100 mg DM) of 70% wheat straw and 30% concentrate we...

there are a little information about nutritive value of alfalfa harvested at different cuts and different cutting time (morning and afternoon) in semiarid climate condition of north east of iran. effects of different harvesting cuts and cutting time (6 a.m and 6 p.m) of alfalfa hay at early bud stage on chemical composition and in vitro gas production fermentation profiles were studied in this ...

in this experiment, different doses of zataria multiflora (zm) and eucalyptus globolus (eg) essential oils (eos) (0, 100, 250, 500, 750 and 1000 µg/ml) and a mixture of them were added to alfalfa hay incubated with buffered rumen liquor of merghoz goat to assess in vitro gas production, rumen fermentation and protozoa population. in all treatments the asymptotic gas volume (b) and the rate cons...

An in vitro gas production technique was used to investigate the associative effects of untreated or biologically-treated linen straw with berseem hay (H). The linen straw (LS) was biologically treated with white rot fungi (TLS). Ground samples (200 mg DM) of H, LS, TLS and the mixtures (50% w/w) of H + LS and H + TLS were incubated in 100 ml glass syringes with buffered rumen fluid. Cumulative...

Three commercial plant tannin and a yucca extract having different secondary compound profiles were simultaneously evaluated in vitro for their effects on ruminal methane gas production and rumen fermentation patterns of wheat forage. Overall objective was to quantify in vitro, the sources of tannins and dose levels of tannins and yucca extract on rate of gas production, ruminal fermentation, f...

the present experiment was carried out to investigate the nutritive value of banana tree leaves and stems silage by use of in vitro gas production and as well in situ nylon bag techniques. experimental treatments were comprised of: 1- stems and leaves of banana trees (control), 2- stems and leaves of banana trees’ silage without addition of any additive, 3- stems and leaves of banana trees’ sil...

This study was conducted to determine the chemical composition, metabolizable energy, digestibility and ability of gas production of Poa trivialis. Samples was collected at three phenological stages including: vegetative growth, flowering and seedling on two different elevations of 1300 to 1500 m and 2000 to 1800 m asl in Neor and Hir region as the first and second sites, respectively. Testing ...
