the aim of the present study was the estimation of (co) variance components and genetic parameters for body weight of moghani sheep, using random regression models based on b-splines functions. the data set included 9165 body weight records from 60 to 360 days of age from 2811 moghani sheep, collected between 1994 to 2013 from jafar-abad animal research and breeding institute, ardabil province,...

studbook information collected from 1988 to 2011 in jafarabad breeding station of moghani sheep, north-west of iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. lambs born during 2009-2011 were considered as reference population. means inbreeding and average coancestry for t...

in this study, 100 moghani sheep from breeding station located in jaafarabad, moghan were genotyped for exon 1 of igf-i gene, using pcr-sscp. different band patterns were obtained in this site gene that was studied. based on sscp patterns, three genotypes bc, bd and bb obtained with frequencies of 65%, 26% and 9%, respectively. the genotype frequencies had a significant deviation from hwe. in a...

This study was carried out to evaluate the effects of nano selenium (nano-Se) and conjugated linoleic acid (CLA) on performance, biometric and blood parametersand selenoprotein W1 (SEPW1) and lipid gene expression in male Moghani lambs. Thirty male Moghani lambs, 3-months-old and weighing 30 ± 0.25 kg, were used in completely randomized design in a 2 × 3 factorial arrangement with dietary suppl...

Oxidative stress during freezing-thawing reduces sperm motility, viability, membrane functions and antioxidant capacity. Thymus vulgaris has antioxidant properties due to phenolic compounds. The purpose of current study was to evaluate the effect of Thymus vulgaris extract as a natural antioxidant on post-thawed Moghani ram sperm quality. Semen samples were collected twice a week from four rams...

the data used in this research were according to survival rate records of 9700 lambs from 735 rams and 8082 ewes, which collected at moghani flock breeding research station during the year 1365 to 1390. the frequency distribution causes of culling and survival distribution function of lambs to yearling age were estimated by sas (2000). results revealed that 49.81 percent of total lambs were cul...
