baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...
the current study was designed to estimate the frequency of igf-i gene 1 polymorphism and investigate if their polymorphisms have association with biometric traits in moghani sheep by pcr-sscp method. for this purpose, a number of 100 sheep were randomly chosen from moghani sheep jafarabad, moghan breeding station that located in ardabil state and blood samples were collected from the left jugu...
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
tumor necrosis factor -alpha (tnfα) is a proinflammatory cytokine that plays critical roles in the regulation of immune responses including macrophages activity and apoptosis. tnfα gene is polymorphic and its haplotypes have been associated with resistance or susceptibility to disease. this study was undertaken to identify the polymorphism of tnfα gene in makoei sheep, using polymerase chain re...
association of genetic polymorphism in the calpastatin (cast) gene with average daily gain was examined in iranian purebred kurdi sheep. the genotypes for cast were determined by the pcr-sscp method. blood samples were collected from 84 purebred kurdi sheep belonging to the kurdi breeding station located in the khorasan province, north-east of iran. extraction of genomic dna was based on the gu...
For genetic analyses of growth traits of Kermani sheep including body weight at birth, three, six, nine and twelvemonths of age, 10, 459 body weight records measuredon 3132 animals originated from 78 sires and 1163 dams were used. The data were collected at Kermani sheep breeding station during 1988 to 2010. The data were analyzed using a multivariate animal model. In the model, animal age, sex...
In this research, investigation of genetic, phenotypic and environmental trends of biometric traits in Makuie sheep was performed using collected data from 1989 to 2012 at Makouei sheep breeding station. Estimation of trends was performed by multivariate animal model using the DFREML software. Genetic, phenotypic and environmental trends were estimated by regression of breeding values average, ...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
in this study, the number of 1802 longevity records of ewes collected during 1989 to 2010 in breeding station of lori-bakhtiari sheep flocks were used to estimate of genetic, environmental and phenotypic trends for economic lifetime. the breeding values of a ewe’s lifetime were estimated by restricted maximum likelihood procedure under an animal model of univariate analysis. the best linear unb...
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
