Bayesian Estimates of Genetic Relationships between Growth Curve Parameters in Shall Sheep via Gibbs Sampling
The objective of this study was to estimate variance components and genetic parameters for growth curve parameters in Shall sheep. Studied traits were parameters of Brody growth model which included A (asymptotic mature weight), B (initial animal weight) and K (maturation rate). The data set and pedigree information used in this study were obtained from the Animal Breeding Center of Iran and co...
متن کاملEstimates of genetic parameters for growth traits in Kermani sheep.
Birth weight (BW), weaning weight (WW), 6-month weight (W6), 9-month weight (W9) and yearling weight (YW) of Kermani lambs were used to estimate genetic parameters. The data were collected from Shahrbabak Sheep Breeding Research Station in Iran during the period of 1993-1998. The fixed effects in the model were lambing year, sex, type of birth and age of dam. Number of days between birth date a...
متن کاملEstimates of genetic parameters for fat yield in Murrah buffaloes
AIM The present study was performed to investigate the effect of genetic and non-genetic factors affecting milk fat yield and to estimate genetic parameters of monthly test day fat yields (MTDFY) and lactation 305-day fat yield (L305FY) in Murrah buffaloes. MATERIALS AND METHODS The data on total of 10381 MTDFY records comprising the first four lactations of 470 Murrah buffaloes calved from 1...
متن کاملEstimates of genetic parameters from a hybrid derivative in Nicotiana.
I N 1918, FISHER described the genotypic variance as consisting of additive genetic, dominance, and epistatic components. This model was later extended by FISHER, IMMER, and TEDIN (1932) to include the action of any number of genes in the absence of epistasis. WRIGHT (1935) presented a model dealing with epistatic effects of loci in pairs, as has GRIFFING (1950) in a constant parent regression ...
