To estimate (co) variance components and investigate genetic and phenotypic trend for reproduction traits in Moghani sheep, data were used from Moghani sheep animal breeding station during 1994-2008. Genetic parameters and correlation between traits were estimated with univariate and bivariate animal models using restricted maximum likelihood (REML) method. Phenotypic and genetic trends calculated using regression of phenotypic and genetic average value on birth year of ewe. Direct heritability of age at first lambing was 0.344, heritability and repeatability of number and weight of born and weaned lamb were at ranged of 0.038 to 0.066 and 0.085 to 0.134 respectively, and direct genetic correlations among studied traits were positive and ranged from 0.61 for TLWB-TLWW to 0.98 NLB-NLW. Also, correlation between ages at first lambing with other traits estimated low to moderate. Genetic trend was estimated -0.018 (year) for age at first lambing, 0 for number of born and weaned lamb, -0.001 (kg) for weight of born lamb and 0.009 (kg) for weight of weaned lamb.
