data on 361 lambs of mehraban (n=90), ghezel (n=92), ghezel × mehraban (n=87), and mehraban × ghezel (n=92, sire breed listed first) were used to estimate individual heterosisfor lamb growth. the obtained results demonstrated that lambs of purebreds of ghezel and mehraban showed the highest and the lowest birth weight, respectively (p

the effect of crossbreeding between ghezel and mehraban on growth performance and carcass characteristics was studied for two consecutive years using 162 purebred and crossbred lambs. the four groups of lambs involved in the study were purebred mehraban (mm), purebred ghezel (gg), crossbred ghezel ram×mehraban ewe (gm) and crossbred mehraban ram×ghezel ewe (mg). the lambs were fed with grazing ...

The aim of this study was investigation of various levels of vitamin E in Tris extender on semen characteristics of Ghezel rams in pre and post freezing conditions. Semen was collected from six healthy and mature rams with average 55±5 Kg body weight by electro ejaculator. High quality samples were mixed and diluted in Tris extender after apply different concentration of vitamin E. Treatments w...

background: ghezel sheep are highly prolific and one of the local sheep breeds in iran and turkey. growth differentiation factor-9 (gdf9) gene has been found to be essential for growth and differentiation of early ovarian follicles. novel mutations in gdf9 have been associated with increased ovulation rates and high litter sizes in heterozygous carriers. therefore, fecundity gene for gdf9 (fecg...

Image processing technique was used to compare udder morphological characteristics in two Iranian crossbred sheep populations including Ghezel-Arkhamerino, Moghani-Arkharmerino and a pure one that was Ghezel ewes. In addition, the resulted measurements were applied as independent variables for estimation of daily milk yield by regression models. Udder height of Ghezel was higher than Ghezel-Ark...
