An Investigation on Population Structure and Inbreeding of Sangsari Sheep
The aim of this study was to describe inbreeding and population structure in Sangsari sheep breeding station. For this reason, data from 7028 Sangsari sheep which were collected during 1987-2014 in Sangsari sheep breeding station located near to Damghan city, Semnan province were used. Lambs born during 2010-2014 were considered as reference population. The genetic structure analysis of the pop...
متن کاملstudy of pedigree structure and effects of inbreeding depression on growth traits in lorestan native sheep
inroduction: inbreeding is defined as the probability that two alleles at any locus are identical by descent and occur when related individuals are mated to each other. the initial consequence of inbreeding is inbreeding depression reducing the performance of growth, production, health, fertility, and survival traits. this concern has become more serious in animal breeding nowadays, in which se...
متن کاملEstimation of Inbreeding Coefficients Using Pedigree and Microsatellite Markers and Its Effects on Economic Traits of Shirvan Kordi Sheep
In this study, pedigree data of 7170 lambs produced from 177 rams and 2182 ewes collected during 1989 to 2009 in the Shirvan Kordi sheep breeding station, were used for calculating inbreeding coefficients. The impact of inbreeding on the studied traits was investigated by including inbreeding coefficients for each animal as a covariate in the animal model. Average inbreeding coefficient of the ...

Inbreeding Effect on Genetic Parameters of Economic Traits in Moghani Sheep Breed
The aim of this study was to investigate the effect of inbreeding on the estimation of genetic parameters of weight traits at different ages in Moghani sheep. In the present study, the information of 11721 Moghani sheep in Jafarabad Moghan breeding station from 1987 to 2011 was used. Genetic parameters were estimated using single trait model with covariate and classification and without inbree...
