Divergent Selection under Two Nutritional Environments for Packed Erythrocyte Volume in Japanese Quail.

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 ...

Selection for Body Weight in Japanese Quail under Different Nutritional Environments

Productive, reproductive performance and biochemical parameters of short-term divergently selected Japanese quail lines and their reciprocal crosses

The current study investigated the effect of short-term selection for four week body weight (BW) on performance of divergent lines of Japanese quail and their crosses. The mean of BW at hatching time, one, two, three and four week oldand BW at sexual maturity time, age at sexual maturity, number of eggs (from 50 to 100 days old), mean of egg weight, percentage of fertility and hatchability in e...

Haematological Profile And Erythrocyte Indices In Different Breeds Of Poultry

The present study was undertaken to evaluate haematological profile viz. Haemoglobin (Hb), Packed Cell Volume (PCV) and Red Blood Cell (RBC) count and erythrocyte indices viz. Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) in different species of poultry and this could be used for clinico pathological diagnosis and further...

Response 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...
