five species of dominant halophyte plants including: salsola griffithii, chenopodium album, aeluropus logopoidies, alopecurus textillis and cardaria draba were sampled from sistan region at their late vegetative stage. the collected samples were dried at room temperature and ground, and their chemical components including: dry matter, organic matter, ash, crude protein, crude fat, as well as ce...

to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...

Two species of rumen fungi, Piromyces (Piromonas) communis FL and Caecomyces (Sphaeromonas) communis FG10, were cultured alone or in association with the cellulolytic bacteria Ruminococcus flavefaciens or Fibrobacter succinogenes on maize stem. A kinetic study of the degradation of the substrate was then made. After 48 h of culture, all non-lignified tissues observed by scanning electron micros...

The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

the possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. in first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. then, the sample product was analyzed to assess its chemical structure, and ...

The study aimed at assessing the prevalence of poor rumen development, presence of rumen plaques, rumen papillae hyperkeratinization, and abomasal lesions in veal calves and to investigate risk factors for their occurrence at the farm level. Within a wide cross-sectional study, a sample of 170 veal farms representative of the European veal meat production systems was considered in the 3 major p...

the effect of eucalyptus (eucalyptus globulus labill;egeo) and angelica (heracleum persicum desf. ex fischer; hpeo) essential oils was assessed at the levels of 0, 3, 30, 300 or 3000 (µl 30 ml-1) on in vitro fermentation of buffered rumen fluid from 3 castrated male sheep. the fermentation kinetics were estimated after 54 hours incubation. the fermentation kinetic values, in vitro gas productio...

ABSTRACT The aim of this study was to evaluate the effect exogenous amylase on gas production, in vitro dry matter digestibility (IVDMD), and digestion kinetics sorghum (Sorghum vulgaris) two corn hybrids different grain textures. Ruminal fluid collected from rumen-fistulated cows receiving or not (0.7g kg-1 (DM basis)), provided achieve 396 kilo Novo units for activity basis). Gas production m...
