The aim of this study was to determine the chemical composition and in vitro digestibility, and to estimate the in vitro fermentation parameters of palm leaves and pedicels from Ghars palm variety. A rumen in situ technique was also used to examine In vitro Digestible Dry Matter (IDDM), In vitro Digestible Crude Protein (IDCP), and In vitro Digestible Neutral Fiber (IDNF), and rate and extent o...

the present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. in the in situ experiment dacron bags were filled with 3 g alfalfa hay. this was incubated in the rumen of three ruminally cannulated ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...

the aim of this study was investigating the effect of gamma irradiation and naoh treatment of some agricultural by products (tomato pulp, orange pulp, pistachio hull and wheat straw) on fermentation parameters and gas production test. treatments of gamma irradiation (50, 100 and 200 kgy) and %5 naoh was done on each source of by products. the results showed that gamma irradiation at the dose of...

abstract             the aim of this study was to evaluate the effect of ajowan essential oils (aeo) on rumen fermentation using in vitro gas production. therefore, different doses of aeo (i.e., 0, 150, 300, 450 or 600 ppm) were added to the syringes of the gas production. a typical diet of growing lambs was used as fermentation substrate.  at the first step, the gas production syringes were in...

Two experiments (Exp.) were conducted to determine the effects of dietary addition of five herbal plants (HP) alone or as herbal plant mixture (HPM) on in vitro gas production and ruminal fermentation patterns. In Exp. 1, five varieties of HP (garlic, eucalyptus, cinnamon, thyme, and peppermint) were added to the diet at 3 different concentrations (5, 10 and 15% of concentrate dry matt...

the aim of this study was to investigate the fermentation characteristics and cellulolytic enzymes activities of dromedary camels rumen anaerobic fungi in fed with cultivated and pasture forages. hence, the inoculant of rumen anaerobic fungi was prepared by using specific medium and the gas production, digestibility and enzyme activity of rumen fungi were determined on the basis of a 2 × 2 fact...

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...

Sheep adapted to consume tannins rich feeds such as oak leaf (OL) appear to develop defensive mechanisms by their ruminal bacteria against these polyphenols. The capabilities of ruminal isolated tannins resistant bacteria from these animals to ferment a tanniniferous feed (i.e., pistachio hulls, (PH) which were incubated with rumen fluid from Holstein dairy cows was assessed. Six g positive coc...

the aim of the current study was the screening the activity of 23 medicinal plants for decreasing the in vitro ruminal methane production, as well to and assess sheep ruminal in vitro fermentation parameters. 57.3 mg of each medicinal plants along with 142.7 mg control diet were weighted in 120 ml wheatons in 4 replicates. the samples were incubated using ruminal fluid obtained from 3 castrated...
