determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. near-infrared reflectance spectroscopy (nirs)was used to analysis the nitrogen (n), acid detergent fiber (adf), dry matterdigestibility (dmd) and metabolizable energy (me) content of three phenological stages(vegetative, flowering and seeding) of bromus tomentellus samples in ...

Background: Grass pea (Lathyrus sativus L.) is valued for its high dietary protein content, degree of adaptability under extreme conditions, disease resistance and low input requirement cultivation. This species represented by several sub-species important varieties which are not well distinguishable their morphological characters. The objective present study was to determine the cultivar diffe...

abstract             this study was conducted to investigate the effects of different levels of yeast and molasses on chemical composition and nutritional value of artiplex lentiformis silage. the levels of yeast include: zero (control), 2.5 and 5 g/kg dry matter and levels of molasses include: zero (control), 10 and 15 percent that were added to atriplex and then ensiled. the experiment arrang...

this study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (p-pb) on in vitro gas production using fistulated sheep. one portion of p-pb was mixed with four portions of water for 48 h. the extracted product was sprayed on soybean meal (sbm) or canola meal (cm) with an equal ratio (1:1 v/w) and dried in the shade. the expe...

Smirnovia iranica, a native valuable woody species from Fabaceae, is an adaptable plant of central sandy areas of Iran. On other hand, this species could be markedly considered from different view points of forage production, soil conservation and medicinal applications. The current research was carried out in Band-e-Rig of Kashan, Iran to evaluate Smirnovia iranica properties including crude p...

It is somewhat ironic that although youth today are saturated in media, no standardized instrument exists to measure individual differences in exposure to specific media content. Therefore, we developed and validated a scale to measure both the frequency and content of adolescents’ media exposure, which measures media exposure regardless of media channel: the Content-based Media Exposure Scale ...

The reduction of a partially deprotonated bishydroxylamine complex {(Bu2Ga)2[cyclo-ON(Me)(CH2)2(Me)NO][HON(Me)(CH2)2(Me)(H)NO]} with a reagent composed of titanium tetrachloride and methyllithium leads to the reduction of one of the N–O groups to an amine function affording the salt {(Bu2Ga)[cycloON(H)(Me)(CH2)2NHMe]} {tBu2GaCl2}−. This has been characterised by 1H and 13C NMR spectroscopy, by ...

Two studies investigated the effect of a thermo-tolerant E.coli-derived phytase (QuantumTM) on performance and bone parameters of broilers fed diets varying in content of available phosphorus (AP), metabolizable energy (ME) and total lysine (TLYS). A 48-day floor pen trial used 80 pens of 16 male broilers fed corn/soya/meat-bone meal based diets formulated to commercial averages (AS) or below. ...

in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...
