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 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...

in the present research, divergent selection for japanese quail body weight at four and five weeks of age was performed in five generations to estimate the response to selection and realized heritability. the average body weight was significantly (p
متن کاملComparision of Direct and Indirect Response to Selection for Breast Weight in Japanese Quail
This study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk BW)) and four-week breast weight (4 week breast weight (wk BRW)) and to determine the genetic contribution of reminder founders to the last generation. A total number of 351 birds were equally allocated to three lines, including two selected lines (S1 and S2 for BW...
