The aim of the present study was to evaluate in vitro and in vivo ruminal fermentation of micronised wood powder in beef cattle. Micronised wood powder was prepared by pulverizing sapwood of Japanese cedar to a mean particle size of 52 μm. Ruminal fluid from four beef cows was anaerobically incubated with different amounts of micronised wood powder (50, 100, 200, or 400 mg per 30 ml rumen fluid...

The role of Vi-capsular polysaccharide (Vi-CPS) in human immunity against infection caused by Salmonella typhi is well known. The downstream process of purification generally causes depolymerization of Vi-CPS to a nonimmunogenic low molecular weight form. In the present study, a standard strain of Sal. typhi Ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 Liter fe...

OBJECTIVE The effects of particle size of processed barley grain, enzyme addition and microwave treatment on in vitro dry matter (DM) disappearance (DMD), gas production and fermentation pH were investigated for feedlot cattle. METHODS Rumen fluid from four fistulated feedlot cattle fed a diet of 860 dry-rolled barley grain, 90 maize silage and 50 supplement g/kg DM was used as inoculum in 3 ...

A portable microfabricated capillary electrophoresis (CE) instrument is used for the determination of neurologically active biogenic amines, especially tyramine and histamine, in fermented beverages. The target molecules are labeled on their primary amino groups with fluorescamine in a 10-min reaction, and the samples analyzed directly, producing a detailed electropherogram in only 120 s on a m...

pervious studies have shown that pentoxifylline (ptx) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. however, there is very little and controversial information about the effect of ptx on brain edema in cerebral ischemia. therefore, the aim of this study was to determine the effects of different doses of ptx on brain edema and neurological motor...

The aim of this work was to investigate the effect of feeding ethyl-3-nitrooxy propionate (E3NP) and 3-nitrooxypropanol (3 NP), 2 recently developed compounds with potential antimethanogenic activity, in vitro and in vivo in nonlactating sheep on ruminal methane production, fermentation pattern, the abundance of major microbial groups, and feed degradability. Three experiments were conducted, 1...

The present study was carried out to evaluate the effect of methanolic extracts of three plants, mehandi (Lawsonia inermis), jaiphal (Myristica fragrans) and green chili (Capsicum annuum) on methanogenesis, rumen fermentation and fermentation kinetic parameters by in vitro gas production techniques. Single dose of each plant extract (1 ml / 30 ml buffered rumen fluid) and two sorghum fodder con...

a dissolved methane sensor based on silicone tube was designed, constructed and optimized.the silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.a continuous stream of helium (50 ml/min) was directed through the tubing, sweeping out the dissolved methane which diffused through the walls of the tubing from t...
