cDNA array analysis of Japanese quail lines divergently selected for four-week body weight.
Decades of divergent selection for 4-wk BW has produced 3 lines of growth-selected Japanese quail. P line quail have been selected for >110 generations for 4-wk posthatch BW and are nearly 3-fold larger than the randomly bred control C line. The H line has been selected for high 4-wk BW for 52 generations and the L line has been selected for low 4-wk BW for 54 generations. To identify different...
متن کاملQuantitative trait loci for body weight and carcass traits in Japanese quail
Body weight (BW) and carcass traits are complex and important economic traits that may benefit from the implementation of MAS. The objective of the current study was to identify QTL associated with BW and carcass traits in an experimental half-sib cross of Japanese quails selected for BW at 4 weeks of age. Body weight and carcass traits were measured in the F2 population. Total F2 individuals a...
متن کاملGenetic Evaluation and Trends of Japanese quail Data Selected for 4-wk Body Weight
The present study aimed to estimate the genetic parameters and evaluate the genetics trend of body weight traits and right shank length of Japanese quail data selected two generation for 4-wk body weight. Body weights heritability (h 2 ) estimates ranged from moderate to high and revealed that selection in HL individuals is probably more efficient at later ages. For shank length, heritability v...
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...
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 ...
