introduction lamb production is the largest part of income in sheep industry. therefore, the mortality rate of lambs is a key factor in profit of the sheep breeding. mortality rate of lambs (or lamb mortality rate) in different breeds of sheep under different climatic conditions is varying from 15% to 50% and an average of 9% to 20% has been reported. survival rate is a combination trait that i...

thriteen thousand, seven hundred and fifty two (13752) records on growth tarits (birth weight, 1, 3, 6, 9 and 12 month weights) as well as pelt scores, collected during 1996-2002 as karakul sheep breeding station, sarakhs, iran were employed in this study. best liner unbiased prediction (blup) of breeding values, genetic and phenotypic trends of the traits were estimated as the regression of av...
