Genetic 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 کاملEstimation of Body Weight from Heart Girth in Sardi and Timahdite Sheep Using Different Models
The objective of this study was to determine the relationship between body weight (BW) and heart girth (HG) in Sardi and Timahdite sheep in order to develop a prediction equation of BW from HG. The data used for this study included 476 records on BW and HG (227 in Sardi and 249 in Timahdite) collected on males and females of different ages in 33 private farms. The BW and the HG averaged 34.8 ± ...
متن کاملEstimation of genetic and phenotypic trends for body weight traits of sheep in Guilan province of Iran
The main objective of the present study was to estimate genetic and phenotypic trends for body weight traits in Guilan province sheep. Traits included were birth weight (BW, n=14,549), 3-month weight (3MW, n=13,109) and 6-month weight (6MW, n=10,141). Data and pedigree information used in this study were collected during 1994 to 2011 by the Agricultural Organization of Guilan province in Iran. ...
متن کاملGenetic analysis of ewe body weight in Lori-Bakhtiari sheep using random regression models
(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
a study on inbreeding coefficient trend of lamb and parents and its effect on wool weight of iran black sheep in animal breeding station of abbas abad
effects of lamb and parents coefficient of inbreeding (ci) on wool weight were studied using 10,868 wool records belonging to 3,244 iran black lambs (1,633 males and 1,611 females) representing 96 rams and 995 ewes collected during 1983-2006 from animal breeding station of abbas abad. year and month of shearing, ci of lamb and dam, sex and birth type had significant affect on wool weight among ...
