Parameter estimates for greasy fleece weight of Rambouillet sheep at different ages.
Variance components for greasy fleece weight in Rambouillet sheep were estimated. Greasy fleece weight was modeled either as repeated measurements on the same trait or as different traits at different ages. The original data were separated according to the age of the ewe at shearing into three classes; 1 yr, 2 and 3 yr, and older than 3 yr. An animal model was used to obtain estimates of geneti...
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 کاملGenetic parameter estimates of body weight traits in Iran-Black sheep
The objective of the current study was to estimate the genetic parameters for body weight traits at different ages in Iran-Black sheep. Data collected during a 24-year period (1984-2008) on body weight were used to model the growth trajectory and estimate genetic parameters. Studied traits were birth weight (BW), weaning weight at 3 months of age (WW), 6 months weight (6MW), 9 months weight (9M...
متن کاملEstimates of genetic and environmental (co)variances for live weight and fleece traits in yearling South African Mutton Merino sheep
Yearling live weight and fleece trait data were obtained from between 2214 and 2270 yearling SA Mutton Merino progeny of the Elsenburg flock during a 20-year period from 1983 to 2002. Information of (co)variances for these traits in SA Mutton Merinos is exceedingly scarce in the literature. Estimates of (co)variance components and ratios were thus obtained from these data, using an Animal Model...
متن کاملestimation of genetic, phenotypic and environmental trends for body weights at different ages in lori sheep
introduction lori sheep is one of the most important breeds in iran that is mostly bred in lorestan province, north-east of khuzestan and some areas of ilam provinces. the name of this breed is derived from lori tribe, which is one of the major nomadic groups of zagros mountain in western areas of iran. lori sheep is resistant to mountain conditions and hot and dry plains. this sheep breed has ...
