Divergent selection for four-week body weight in Japanese quail (Coturnix coturnix japonica): response to selection and realized heritability
The Japanese quail has been utilized as a research species in establishing the genetic relationships that may also be present in other species. Divergent phenotypic selection for 4-wk BW was conducted for three generations in high (HW) and low (LW) lines. Within each line, 50 females and 25 males were selected among 600 birds, based on 4-wk BW. Mean BW at 4 wk of age in the base generation was ...

متن کاملResponse 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 ...
متن کاملthe effect of divergent selection for 4-wk body weight on growth curve parameters and carcass components in japanese quail (coturnix coturnix japonica)
this study has been carried out to investigate the effect of short-term divergent selection for 4-wk body weight on growth curve parameters and carcass components in japanese quail. quail lines utilized were two divergently selected for high (hw) and low (lw) 4-wk body weight (bw) as well as a line as control (c). the results of the study indicated that quails in hw line had heavier bw than tho...
متن کاملResponse to Selection for Body Weight in Japanese Quail (Coturnix coturnix japonica)
The present studyinvestigated the impact of selection for body weight (BW) on productive performance, predicted BW and genetic improvement of related traits in Japanese quail. Base population, selected parent and F1 progeny were tested. Pens and cages were used for rearing and breeding. A total of 240 birds in two successive generations, 27 sires and 54 dams (as selected parents) were used. Bod...
