Divergent Selection under Two Nutritional Environments for Packed Erythrocyte Volume in Japanese Quail.
Two-way selection for two-week packed erythrocyte volume (PCV) was practiced for four generations under two nutritional environments in the Japanese quail (Coturnix coturnix japonica). One environment was an iron, copper-"adequate" diet and the other was iron, copper-deficient "stress" diet. Response to selection was greater in both directions under the adequate environment than under the stres...
متن کاملDivergent 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 کاملeffect of divergent selection for body weight on egg production and other reproduction traits in japanese quail
the aim followed in the present research was to investigate the effect of nine generations of divergent selection on some reproductive and egg production traits in japanese quail. the results indicated that selection for 4-week body weight, increased the age at sexual maturity of hw and of lw lines, in comparison with control, for about 7 and 3 days, respectively (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...
