in this study, production, reproduction, managerial, and economic parameters obtained from data recorded for lori-bakhtiari flock of sheep (500 heads of breeding ewe) stationed at the sheep's breeding station, were employed to determine the relative economic values of and breeding objectives for an annual cycle of production, in village system in this breed of sheep. economic value for a t...
متن کاملPhenotypic 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 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...

متن کاملHistological Feature of the Skin at Different Regions and in Different Ages of Lori-bakhtiari Sheep
For this study, 24 Lori-Bakhtiari sheep were selected and divided into four age groups: 1-10 days, 5-8 months, 1-2 years and 3 and more years. In each age group, six animals (3 of each sex) were used. The specimens of eight different skin regions were collected. They were fixed in 10% formaldehyde solution and processed through routine paraffin embedding, cut at 5-7 μm and stained with haematox...
