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 stay-green mutation of the nuclear gene sid results in inhibition of chlorophyll degradation during leaf senescence in grasses, reducing N remobilization from senescing leaves. Effects on growth of Lolium perenne L. were investigated during N starvation (over 18 d) and after severe defoliation, when leaf growth depends on the remobilization of internal N. Rates of dry mater production, part...

The effect of adding increasing levels (0, 25, 50 and 75 μl/75 ml buffered rumen fluid) of essential oils (EOs) to a basal substrate (50% roughage: 50% concentrate) on ruminal fermentation characteristics was evaluated in vitro by a semi automatic gas production (GP) technique. The EOs used were from Achillea santolina (AS25, AS50, AS75), Artemisia judaica (AJ25, AJ50, AJ75), Schinus terebenthi...

this study was conducted to investigate the effects of different doses of salvia mirzayanii essential oils on gas production parameters, fermentation characteristics using gas production and dual flow continuous culture system. trearments in the gas production experiment was adding 0, 400, 800, 1200, 1600, 2000, 2400 and 4800 mg/l of salvia mirzayanii essential oils to the media. in the second ...

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...

Analysis of yielding ability and growth patterns of mash bean (Vigna mungo L.Hepper.) genotypes were carried out on loamy sand soil during kharif season. Genotypic differences were observed with respect to extent of flower production/shedding, podding and crop durations. Plants of Mash338 were dwarf, erect, compact with determinate growth habit whereas Mash1-1 were tall, spreading with indeterm...

shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...

effects of different levels of cadmium (0.1, 1, 2, 4, 8, 16, 32, 64, 128, 256 mg/l of culture medium) were evaluated using gas production technique. in the glass vials used to measure gas production 30 mg of buffered rumen fluid (2:1 ratio of rumen fluid: buffer) poured in glass and cultured at 38.6 temperature. volume and pressure of produced gas were measured with syringes and digital pressur...

Two experiments were conducted to evaluate the effects of microwaving, autoclaving (moist heating), and roasting (dry heating) on gas production parameters and in situ rumen degradability of soybean meal (SBM). SBM was treated by roasting at 140℃ for 30 and 60 min, and at 160℃ for 30 and 60 min, autoclaving at 121℃ for 20 min, and microwaving for 2, 4, and 6 min. A gas production trial...
