Mixed model studies on inheritance of reproductive traits in laying hens - a Bayesian approach.
Segregation analyses performed for many livestock species indicate a mixed inheritance model of reproductive traits. Additionally, depending on the population, a given trait can be determined by a number of genes with large effects. Genetic backgrounds of hatch-ability and fertility in poultry are still not known sufficiently. The objectives of this study are to verify the hypothesis on segrega...
متن کاملGroup records corrected for mortality to estimate breeding values for production traits in laying hens
Records of a White Leghorn Line from three generations were used to evaluate the genetic parameters (heritabilities and breeding values) for production traits in laying hens based on individual and group mean records, taking into account mortality in the data structure. Three different data structures of group mean records, which were Hen Housed Production (HHP), Hen Housed Production corrected...
متن کاملA note on inbreeding effect on productive and reproductive traits in laying hens
Inbreeding rate and effects on production (body weight, age at first egg, egg weight), and reproduction (per cent of eggs fertilized, per cent of eggs hatched as related to eggs set) traits were evaluated in 9194 layers belonging to two strains. The individual inbreeding coefficients were calculated using Wright’s formula from available performance records across nine generations. The inbreedin...
متن کاملEstimation of genetic parameters of litter size in Moghani sheep using threshold model via Bayesian approach
This study was conducted to estimate the genetic parameters of litter size (LS) in Moghani sheep using threshold model via Bayesian approach. The data originated from the Jafar-Abad Station of Ardabil province, Iran, and included 9698 lactation records of 4977 ewes with lambings from 1995 until 2010. The pedigree file consisted of data on animals born from 1987 to 2010. The significance of fixe...
متن کاملBayesian inference of genetic parameters for reproductive traits in Sistani native cows using Gibbs sampling
This study was undertaken to estimate the genetic parameters for some reproduction traits in Sistani beef cattle. The data set consisted of 1489 records of number of insemination, calving, and insemination dates in different calving was used. Reproduction traits including calving interval (CI), gestation length (GL), days open (DO), calving to first service (CTFS), first service to conception (...
