“…Hussain et al, (2013) also reported significant improvement in body weight gain (g) in selected groups of Japanese quails at the age of 21 days. Similarly, Krishna and Sahitya Rani (2017) also reported that the body weight gain was found to be higher in the progeny than the parental population at six weeks of age.…”

“…Wang et al, (2019) also reported that male chicken had better growth performance than female chickens. Furthermore Krishna and Sahitya Rani (2017) reported that body weight of the progeny obtained from baseline and selected female quail population was found to be higher than the parental population body weights at the end of the growth period. Significant effect of sex and line (P < 0.001) was also observed by Khaldari et al, (2010) in Japanese quail selected for 4-week body weight.…”

“…The maintenance requirement of feed has been reported to be increased with increase in body weight of birds which reduced availability of energy required for their growth (Rondelli et al, 2003;Varkoohi et al, 2010;Okenyi et al, 2013). Krishna and Sahitya Rani (2017) also reported that feed conversion ratio of the progeny was found to be better feed conversion ratio compared with baseline and selected population during the growth period.…”

Feathering rate impact on growth and slaughter traits of Japanese quail

et al. 2018

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.

The research was carried out in the poultry unit fields / Nineveh Research Department, to identify the effect of four generations (1st , 2nd, 3rd and 4th) and feather color groups (black, brown, desert and white) of female quail on their productive performance. The results showed a significant improvement (P <0.05) through generations from 1st to 4th on egg production percentage and weight of eggs produced / kg, a significant increase (P <0.05) for feed consumption / kg as well as a significant decrease (P <0.05) for abnormal color percentage, while the four generations had no significant effect on Feed conversion ratio (feed kg / egg kg), age at 5% eggs production / day, hatchability percentage, fertility percentage, and sexual ratio. On the other hand, the desert color group feathers excelled significantly (P <0.05) in eggs weight / kg., Feed consumed / kg and the food conversion ratio / kg eggs compared to the black group only, and the lowest significant percentage (P <0.05) for colors anomalous was of the desert color group, there was no significant difference between the color groups of the rest of the other traits.
