the objective of the present study was to scan the whole genome in sheep for identifying the loci associated with wool diameter. blood samples were collected from 94 animals, consisting 47 samples per each lori-bakhtiary and zel breeds. genotyping of samples were performed using ovine 50k snp chip arrays. quality control filters were applied for the initial genotyping data and 48,056 snps belon...

calpastatin has been introduced as an effective candidate gene as regards growth efficiency and meat quality traits. throughout the present study, blood sampling as well as carcass trait measurements were performed on 74 lori-bakhtiari sheep and on 40 zel-atabay cross-breds from industrial slaughterhouses of shahrekord and gorgan cities, respectively. following dna extaction, polymerase chain r...

The GH gene and BMP15 gene have been used as candidate genes for ­marker-assisted selection in different livestock species. Random blood samples were obtained from 180 Zel sheep breed to study genetic polymorphism of these genes. DNA was extracted from blood samples and a 365 bp fragment from the exon V of the ovine growth hormone gene and a 312 bp region from exon II of BMP15 gene were amplifi...

Agricultural sector accounts for about 1/3 of the Iranian GDP and 1/4 of the country workforce. More than 90% of the Iranian food requirements are produced in the country. Animal agriculture covers over 40% of the agricultural activities. More than 57% of the available animal units in the country are sheep and goats. Desertification, deforestation, water shortage, erosion, low efficiency and ou...

The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...

Problem statement: The IGFs play an important role in regulating somatic growth according to nutritional conditions. Polymorphisms of IGF gene are reported to be significantly associated with many traits. Approach: In these study 142 samples of DNA from Zel sheep were used for detecting the polymorphisms of promoter region of the Insulin-like Growth Factor-1 (IGF-1) gene. Therefore DNA extracte...

this study was carried out by using two hundred ewes (2-4 years old) as  pure breeding (zel × zel) and crossbreeding (chal × zel). in each treatment, 30 male and 30 female lambs were fattened in a feedlot experiment for three periods; 75, 100 and 125 days. at the end of each period, 10 lambs of each treatment were slaughter and carcasses analysis was down. the lean meat percentage and bone perc...
