Quantitative 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 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 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 کاملFunctional development of small intestine of Japanese quail hatched on MIR orbital station.
The effect of microgravity on functional development of the small intestine of Japanese quails incubated for 2-3 d and hatched on the orbital station MIR was examined. After 5 d of space flight duodenal and jejunal alkaline phosphatase (AP) activity of the experimental group was compared with the AP activity in quails of the same age hatched on the Earth (laboratory controls). Short-term microg...
متن کاملRole of Body Weight on Reproductive and Physiological Traits in Japanese Quail Layers (Coturnix japonica)
The Japanese quail is a popular laboratory animal for scientific research. Its continued characterization is essential for attaining accurate and reliable results. This includes refining genetic and environmental variables that could affect its use in developmental biology, reproduction, physiology, nutrition, endocrinology and toxicology. The role of body weight as a means of assessing reprodu...
