Phenotypic and Genetic Factors Affecting on Reproductive Lifetime of Lori-Bakhtiari Ewes
In this study phenotypic and genetic factors affecting the reproductive efficiency of Lori-Bakhtiari ewes were determined using 8202 reproductive records of 2478 ewes collected at Shooli research station in the southwestern part of Iran (Shahrekord) during 1989 to 2012. Reproductive efficiency over all consecutive lambing opportunities were calculated by adding the total reproductive efficiency...

متن کاملGenetic and non-genetic factors affecting morphometry of Sirohi goats
AIM The aim was to estimate genetic and non-genetic factors affecting morphometric traits of Sirohi goats under field condition. MATERIALS AND METHODS The detailed information of all animals on body measurements at birth, 3, 6, 9, and 12 months of age was collected from farmer's flock under field condition born during 2007-2013 to analyze the effect of genetic and non-genetic factors. The lea...
متن کاملPhenotypic and Genetic Analysis of Lori-Bakhtiari Lamb's Weight at Different Ages for Autosomal and Sex-Linked Genetic Effects
The data set used in this study contained 8793 records of lamb's weight (kg) from 320 sires and 2349 dams collected during 1989 to 2014 from the Lori-Bakhtiari flock at Shooli station in Shahrekord, Iran. Non-genetic factors and genetic parameters (partitioned into autosomal, sex-linked and maternal) of lamb's weight at different ages were estimated using without and with sex-linked genetic eff...
