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 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...

متن کاملThe influence of divergent selection for body weight at 63 days of age in rabbits on muscle characteristics at a same age or at similar weight
Two lines of rabbits divergently selected for body weight at 63 days during 6 generations (H: high line; L: low line) and a cryo-preserved control group (C) were used to assess the effects of growth rate on muscle characteristics, either at a fixed age (63 days) or at the same weight (2297 + 10 g). In the two series of slaughter, body weight at weaning (28 days) was decreased in the rank order ...
