In this study, the kinetic of biogas production was studied by performing a series laboratory experiment using rumen fluid of animal ruminant as inoculums. Cattle manure as substrate was inoculated by rumen fluid to the anaerobic biodigester. Laboratory experiments using 400 ml biodigester were performed in batch operation mode. Given 100 grams of fresh cattle manure was fed to each biodigester...
Two rumen protozoa vaccine formulations containing either whole fixed Entodinium or mixed rumen protozoa cells were tested on Merino sheep with the aim of decreasing the number and/or activity of protozoa in the rumen. Negative control (no antigen) and positive control (Tetrahymena corlissi antigens) treatments were also included in the experiment. Blood and saliva were sampled to measure the s...
this study was conducted to evaluate effects of rosemary essential oils (reo) on feed digestibility, blood and rumen parameters of ghezel sheep. four male sheep with average body weight 46±2 kg were used in a 4×4 latin square design. treatments composed of basal diet (control) in addition to diets containing 100 (ro100), 200 (ro200) and 400 (ro400) mg/day of reo. sheep's fed with 4 diets ...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
BACKGROUND: Manipulation of rumen microbial population for improving animal performance is done by several methods including medicinal plants. Matricaria chamomille (chamomile) and Cichorium intybus (chicory) are two medicinal plant with antibacterial effect that there is little information about the effects of them on rumen microflora. OBJECTIVE: The present study was carried out to evaluate t...
abstract the aim of this study was threefold: (1) to investigate the relationship between knowledge of semantic prosody and efl learners general language proficiency; (2) to examine the relationship between qualitative as well as quantitative knowledge of words, and (3) to compare the performance of efl learner on receptive and productive measures of semantic prosody. the study is based on a...
this experiment was carried out to investigate the effect of adaptation period to oak leave's tannin on rumen ph and ammonia, rumen microbial population, gas production and dry matter true digestibility (ivtdmd) in alamout goat’s rumen (with no previous history of oak leaf consumption) compared with markhoz goat (with previous history of oak leaf consumption). the goats were fed either oak...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
