Introduction Among the different factors accounting for the better utilization of poor forages by goats, compared with sheep, urea recycling and better mastication during ingestion have been reported (Masson et al, 1986; Morand-Fehr et al, 1987). Our purpose was to measure the particle size in the alimentary bolus and to indirectly assess urea recycling, by chemical analysis of alimentary bolus.
introduction: land use change, deforestation, grazing, intentional and unintentional fire and invasive pests and diseases are all the major cause of damage to the zagros forest ecosystem. the green oak leaf roller (tortrix viridana l.) is one of the important pests of zagros forests. larvae of the pest significantly damage the oak forests with feeding on leaves and buds of different species of ...
the eggs and larvae of the indian meal moth, plodia interpunctella (hübner), are widely used in mass rearing of parasitoids and predators. feeding indices and some biological parameters of p. interpunctella were studied on bran of different wheat cultivars ('back-cross roshan', 'khooshe pishgam', 'khoshki line 9', 'arg', 'alvand', 'pishtaz', 'ws-89-2', 'sepahan' and 'bam') when incorporated int...
feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae on different ratios of live food and microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
introruction khawf in(iran)-herat and mazaresharif and shirkhan bandar in (afghanistan)-dushanbe in (tajikistan)_(kirgizstan)-kashghar in(china) project railway network is under construction that it is as a significant corridor for revitalizing silk road corridor in the region .at the present there are three different gauge in the region central asia with 1,520 mm gauge and turkey-islamic repu...
Simple and easy methods to evaluate swallowing are required because of the recently increased need of rehabilitation for dysphagia. "Artificial food bolus", but not "artificial food", would be a valuable tool for swallowing evaluation without considering the mastication effect which is altered according to the individual's oral condition. Thus, this study was carried out to fabricate artificial...

Laboratory experiments were conducted to determine the functional and numerical responses of fourth instar larvae, adult male, and adult female ladybird beetles, Anegleis cardoni Weise (Coleoptera: Coccinellidae), to different densities of aphids, Aphis gossypii Glover (Hemiptera: Aphididae), on the bottle gourd, Lagenaria vulgaris Seringe (Cucurbitales: Cucurbitaceae). The results revealed a d...
چکیده نمایشگاه های جهانی یا اکسپو عنوانی ست که از سال 1851 میلادی در لندن توسط همسر ملکه انگلستان شکل گرفت ، هدف اولیه این نمایشگاه ها نمایش دستاورد های صنعتی بود، اما در طول 165 سال که این نمایشگاه های برگزار گردیدند ، رویکرد آنها تغییر کرده است . در هر دوره به یک شعار که در واقع دغدغه اصلی جهان، در آن زمان بوده است ، پاسخ داده شده و راه حل کشور های مختلف در مورد آن موضوع به نمایش گذارده شد...
