the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
The aim of this study was to determine the chemical composition of stem and compost of the button mushroom to estimate metabolizable energy (ME) and net energy of lactation (NEl) using gas production method and to determine the amount of dry matter disappearance (DMD) using in vitro technique. This study was conducted in a completely randomized design with three treatments o...
The aim of this study was to investigate the effect of different levels of aflatoxin on the gas production, in vitro fermentation parameters, dry matter and organic matter digestibility of sheep's diet. This experiment was conducted in a completely randomized design with 5 treatments and 4 replicate per treatment. The treatments included 1.diet without aflatoxin and methanol (control), 2.c...
This study was done to investigate the nutritive value of Festocaovina, Agrostisgiganta and Avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. Rumen and feces liquor were collected from three fistulated sheep. Rangeland species sampling was randomly conducted from different areas of Guilan province. All the collected samples were initiall...
the chemical composition, in situ rumen degradability coefficients of dry matter (dm) and crude protein (cp), in vitro gas production and in vivo digestibility were evaluated for olive cake (oc) silage treated (dm basis) with different additives as follows: (1) untreated oc; (2) oc, 8% molasses and 0.4% formic acid and (3) oc, 8% molasses, 0.4% formic acid and 0.5% urea. after addition of the...
in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...
This study carried out to determine of chemical compositions and nutritive value of five species of range plants in Sistan including Oshnan (Seidlitzia rosmarinus), Rendouk (Salsola yazdiana Assadi), Siyah Shor (Suaeda fruticosa), Shoran (Salsola vermiculata) and Anabasis (Anabasis setifera) by in vitro and in situ techniques. Samples were collected by systematic and random sampling procedure i...
this experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg atriplex forage) malva sylvestris on digestibility and microbial fermentation of atriplex in one-humped camel. fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. addition 40 and 60 mg/kg malva sylvestris increas...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
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...
