“…Warren (1930) indicated that in crosses between males having the gene for fast-feathering rate and females having the gene for slow-feathering rate, gender may be detected by the extent of growth in primary and secondary wing feathers at 1 day old and by the existence or absence of tail feathers at 10 days old. Females have been reported to have significantly higher feather weight (Wecke et al, 2017) and heavier BW (Taskin et al, 2017) than males across generations.…”

A total of 1180 1-day-old Japanese quail (Coturnix japonica) chicks were used to investigate the effect of feathering rates on growth and slaughter traits. Feathering rates were classified based on the results of stepwise regression using numbers and lengths of both primaries and secondaries and tail length at 7 and 10 days of age as predictors. At 7 and 10 days old, number of primary feathers had phenotypically positive low correlations (rps) with body weight (BW), whereas number of secondaries had positive medium rps with BW at different ages. Lengths of primary, secondary and tail feathers had highly positive rps with BW traits at different ages. Results of stepwise multiple regressions indicated that BW at 14, 21 and 28 days of age can be predicted using lengths of secondary and tail feathers at 10 days old, number of secondaries at 7 days old and length of secondaries at 7 days old, respectively. Body weight at 35 days of age can be predicted using number of primaries, lengths of secondaries and tail at 10 days of age and number of secondaries at 7 days of age. Higher BWs were obtained in the fast-feathering class from 21 up to 35 days of age than in other groups, whereas the slow-feathering class had the lowest BW. Significant class differences were found for carcass weight, feather weight and dressing% favouring the fast- over the slow-feathering class. Therefore, early feathering rates improved BW at later ages and slaughter traits in Japanese quail.

“…Also, there were significant higher BW's favoring the selected line, however, the selected line had significantly higher BW1 than the CL (Narendra Nath et al, 2011). Regardless of generation, selected lines for BW had significantly heavier BW35 than the control line (Taskin et al, 2017).…”

“…In addition, there was significant sexual dimorphism of Japanese quail BW favoring females than its counterpart males which occurred as a result of male sexual activities due to the hormonal change. Similarly, Taskin et al (2017) indicated that sex was a significant source of variation for BW at all the ages across selection generations. Similarly, calculated GR1-35 indicated that females had faster GR than males (Daikwo et al, 2014).…”

This study aimed to investigate the effects of selection for high early growth rate during 1-21 days of age (GR1-21) on growth traits, some plasma constituent and carcass characteristics. An experiment was carried out at the farm of the Poultry Research Center, Faculty of Agriculture, Fayoum University and continued for six generations including 10,024 for two lines (the selected line, HGR1-21 and the control line, CL) of Japanese quail chicks. The HGR1-21 had better BW21, BW35, GR1-21, GR1-35 and BWG1-35 than the CL. Generation of selection significantly affected all growth traits. Females had significantly higher BW21, BW35, BWG1-35 and GR1-35 than males. Quails of HGR1-21 had lower high density lipoprotein (HDL) and higher triglycerides (TG) than the CL. Females had higher TG and lower HDL than males. Quails of HGR1-21 had higher carcass %, dressing %, weights of giblets, heart, gizzard and liver than CL by 3.65%, 2.59, 23.79, 68.42, 13.21 and 23.47%, respectively. Females had higher weights of giblets, gizzard and liver than males by +12.41%, 14.64% and 12.34%, respectively. The HGR1-21 had higher ether extract % (+24. 28%) and lower moisture% (-4.79%) than the CL. GR1-21 showed moderate heritability (h 2 ) of 0.28 and ranged from 0.20 to 0.29 for growth traits. The GR1-21 found to be positively genetic and phenotypic correlated (rg & rp) with BW21, BW35, BWG1-35 and GR1-35, with rg ranged from moderate to high (0.24 to 0.70) and rp ranged from low to medium (0.03 to 0.41), however there were negative rg and rp between GR1-21 and BW1 being -0.15 and -0.50,respectively. Genetic response showed superiority of the selected line than the control (P< 0.05) for selection criteria (+0.04) .Selection for GR1-21 had desired genetic gain with all studied growth traits, except BW1. Also, carcass traits and vital organs were improved due to selection for GR1-21.

“…At 38 weeks of age, the average body weights of male and female quails were 109.38g and 117.92g respectively. Taskin et al (2017) showed that quails of different weight had the following differences: Significant differences were observed for total egg production and egg width for Group X Generation's interactions.…”

This study was carried out to evaluate growth and development and difference between size and weights of three quail species namely China yellow quail, Beijing white quail and Korea quail. Various parameters in respect of these species like shank length, chest width, chest depth, breastbone length, shank circumference, body length, daily weight gain and weight were recorded under similar feeding conditions. The data so obtained was analysed statistically using SPSS. It was revealed that the body weight, shank length, chest width, chest depth, breastbone length, body length, shank circumference and daily gain of Korea quail are significantly higher (P£0.05) than those of China yellow quail and Beijing white quail. It was concluded the Korea quail grows fastest, followed by China yellow quail and Beijing white quail, successively.
