Evaluation and genetic analysis of egg production and egg quality traits in Rajasri birds
... In this investigation, the average yolk colour was 6.58±0.12, which is similar to Rajasri chicken reports (Hussain et al., 2017) [5] . In contrast, Ghagus and PD-4 (Haunshi et al., 2015) [4] , Vanaraja male line (Padhi et al., 2013) [10] , Aseel and Kadaknath (Haunshi et al., 2011) [3] revealed greater values than the current study. ...

... (Table 1). These results are similar to the reports of (Kalita et al., 2012 andHussain et al., 2017), but are slightly higher than those observed by (Sankhyan and Thakur 2016) in Vanaraja female line chicken. However, slightly lower values were also reported among native breeds, by Singh et al. (2000). ...
... Similarly, the mean hatchability percentage on FES ranged from 83.13 to 90.47 per cent with an overall hatchability percentage of 86.95 (Table 1). Similar hatchability (TES) estimates were reported by Sankhyan and Thakur (2016) in Vanaraja, Hussain et al. (2017) in Rajasri chicken. Higher hatchability was reported by Rajkumar et al. (2012b) in Gramapriya male line birds, whereas lower hatchability (TES) estimates were reported by Kalita et al. (2012) ...
Balakrishna, R.G., Chinni, P.V., Gnana, P.G., Rajkumar, U., Gurram, S., Sai, R.S. and Mounika, T. 2024. Evaluating the performance of Vanaraja female line (PD-2) chicken for fertility, hatchability, body weight, shank length and keel length. Indian Journal of Poultry Science, 59(02): 215-219. The present study was aimed at evaluating the performance of Vanaraja female line (PD-2) chicken. Data collected on 3737 chicks, progeny of 50 sires and 250 dams produced in a pedigreed full sib mating at the Directorate of Poultry Research, Hyderabad in four hatches during 15 th generation were utilized for the present investigation for estimating various parameters. The results indicated that the mean fertility was 83.57 percent. The overall mean hatchability percentage was 72.66 on total eggs set (TES) and 86.95 on Fertile Eggs Set (FES). The mean fertility (83.57%) and hatchability (86.95 %) indicating the good reproduction and mothering of the PD-2 population. Highly significant (P<0.01) difference among the four hatches were observed for body weights at day old, 2, 4, 6, 12, 16, 20 and 40 weeks of age and hatch effect was observed for shank length at 4, 6 weeks of age and keel length at 6 weeks of age. Carcass traits such as live weight, dressing, and blood percent were significantly higher in male than female. Percent live weight of liver, gizzard, heart and feathers were significantly (P<0.01) higher in females than males.
... The least squares means of first egg weight is similar to those ofLiu et al (2018), low compared to those ofSreenivas et al (2013) and high compared to those ofYi et al (2014). The studies conducted byRahim et al (2016) andHussain et al (2017), least squares means for egg weight at 40 week was lower, whereas in the findings ofSingh et al (2018) andChurchil et al ...
... Similar values for EP 40 were reported in IWK [39]. Lower heritability estimates than the present study was reported by some authors [32,35,40], whereas higher heritability values were obtained in RIR [41]. Heritability estimates for egg production were low due to less additive genetic variance in the flock. ...
