Response to selection and genetic parameters of body and carcass weights in Japanese quail selected for 4-week body weight.

The current study was conducted to investigate the effect of short-term selection in Japanese quail for 4-wk BW and estimate genetic parameters of BW, carcass traits, and egg weight. A selected line and control line were randomly selected from a base population. In each generation, 39 sires and 78 dams were used as parents for the next generation. Data were collected over 2 consecutive hatches ...

Genetic Parameters Estimated for Sexual Maturity and Weekly Live Weights of Japanese Quail (Coturnix coturnix japonica)

Covariance components and genetic parameters of weekly live body weight from hatching to six weeks of age and age of sexual maturation were estimated in a laying type Japanese quail line. The univariate and bivariate animal model analysis included hatching group and sex as fixed effects. Each trait was analysed with animal as random effect to fit the additive direct effect. Additional random ef...

a study of the effect of individual and family selection on the increase body and breast weights in japanese quail

the current study was conducted to investigate the effect of short-term selection in japanese quail for its 4-week body and breast weights. two selected lines, one for selection of body weight based upon in. breeding values (line 1) and another for breast weight based on between family selections (line 2) were randomly selected from a base population. in each generation, 39 sire and 78 dam-bird...

Genetic parameters for body weight in meat quail

The aim of this study was to estimate genetic parameters for BW in meat quail at different ages. A total of 24,382 weight records from 3,652 quail, born between 2009 and 2011, were evaluated. Weekly BW was measured from hatch until 42 d of age. The genetic parameters were estimated by the restricted maximum likelihood method using a multivariate animal model. Heritability of BW ranged from 0.03...
