In this study 5025 records from the Lori-Bakhtiari sheep stud were used to predict phenotypic, genetic and environmental change in ewe traits from 1989 to 2004. Best linear unbiased prediction (BLUP) of breeding values were estimated by Drivative Free Restricted Maximum Likelihood (DFREML) procedure using single and multi-trait animal model. Phenotypic, genetic and environmental trends were cal...
In this study, 5608 records of Kordi sheep body weights collected during 21 years (1990 to 2010) in Sheep Breeding Station of Shirvan were used to estimate genetic, phenotypic and environmental trends. Best linear unbiased predictions (BLUP) of breeding values were obtained by derivative free restricted maximum likelihood (DFREML) using univariate animal model. Genetic, phenotypic and environme...

in this study the data of 2332 lambs from 815 dams and 61 sires, collected during 1993-2004 in kermani sheep breeding station were used to estimate phenotypic, genetic and environmental trends for birth weight (bw), weaning weight (ww), 6 months weight (6mw), 9 months weight (9mw) and yearling weight (yw). heritability estimates were determined for each trait using derivative free reml procedur...
genetic parameters were estimated in a base and closed population of iranian honeybee colonies. data were obtained on 500-700 iranian native population of honeybee colonies (honeybee breeding project in central region of iran) subject to 9 successive generation of selection. these populations had been selected for honey production, swarming behavior, and defense behavior. heritability of honey...
in this research genetic and phenotypic parameters were estimated using linear and threshold models, for reproductive traits, data from 6 large industrial dairy herd of east azerbaijan province collected by agriculture jihad organization during 10 years (2001-2010). best linear unbiased predictions of traits breeding values were estimated using restricted maximum likelihood method by wombat sof...
The present study aimed to estimate heritability, genetic and phenotypic correlations between body weight and body measurement traits in Iranian Makuei sheep. The used data were collected from 1989 to 2012 at Makuei Sheep Breeding Station in Maku (West Azarbayjan province). The data included body weight and five body measurement traits (body length (BL), heart girth (HG), withers height (WH), r...
Objective(s): The enteroaggregative Escherichia coli (EAEC) has been one of the most intriguing emerging bacterial pathogens in children that occur both in developing countries and the industrial world. Although various phenotypic and genotypic based protocols have been suggested for diagnosis of EAEC, they are not conclusive or practical to be used in most clinical la...
data related to holstein dairy cattle from 1987 to 2004 were obtained from animal breeding center of iran to estimate the genetic and phenotypic trends. variance components and genetic parameters of the first lactation records were estimated using restricted maximum likelihood method and aireml algorithm through matvec program. animal breeding values were predicted through multiple-trait animal...
In this study, estimation of genetic parameters of Lameness and genetic and phenotypic correlations between Lameness and milk, fat and protein yield were performed. The data obtained from 63403 Holstein cows were collected from the Animal Breeding Center of Iran between 2001 to 2013 Estimation of genetic parameters for lameness was performed by univariate animal and Threshold models. Also, esti...
