Estimates 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 parameters for body weight traits in Baluchi sheep
Genetic parameters for birth weight (BW), weaning weight (WW), 6 months weight (6MW), 9 months weight (9MW) and yearling weight (YW) in Baluchi sheep were estimated using data collected during a 26-year period (1984-2010). Estimates of (co)variance components were obtained by REML procedures by fitting a linear mixed animal model. Significant random effects for each trait were explored by fitti...

Genetic and phenotypic parameters for body and yearling fleece weigh traits were estimated based on 4008 records. Records gathered across year 1993 to 2007 in the Markhoz goat research stations in Saghez and Sanandaj. Parameters were estimated using univariate and bivariate animal model with restricted maximum like lihood ASREML software. Mean (standard error of means) of birth weight (BW), w...
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 fleece and post-weaning body weight traits in Makuie sheep.
Estimation of genetic parameters is the most important component of an organized selection program. With respect to economic traits, such as wool and mutton traits, production costs can be reduced through a suitable selection program focused on genetic improvement. This study aimed to evaluate genetic parameters of fleece and post-weaning growth traits in sheep. Greasy fleece weight at 6, 16, 2...
