Three hundred sixty (360) day-old female chicks were randomly distributed into 3 groups. Each group was allotted to one of the three treatments i.e. starter diets containing 18, 19 or 20% CP up to 5th week of age. From each group, out of 120 birds, 96 grower pullets with higher body weight (BW) were selected for the second experiment. The birds of each group (96) were further divided into two groups i.e. high body weight (HB) group and low body weight (LB) group. The pullets of each BW group were randomly distributed in 6 replicate groups. Three of the replicate groups were allotted to grower diets with 10 or 14% CP from 6th to 20th week of age. From 21st to 23rd week, a pre-breeder diet and from 24th week onwards, a breeder diet was offered. The 5th week BW had positive and highly significant correlation (P≤0.01) with overall period (24-50 wee...

The pedigree in the current study descended from 69 sires and 552 dams. Genetic parameters were estimated using sire and dam component of variances for various production and reproduction traits after necessary corrections for hatch effects were done.

Ninety (90) chicks were used for this study. Body weight and feed intake were recorded weekly. The body conformation traits were measured at 6 th and 8 th weeks of age. The 8 th week body weight of males and females were 1016.97±45.13g and 830.33±19.64g respectively. The weekly feed conversion ratio (FCR) increased progressively from 1.50±0.08 at 1 st week to 4.38±0.89 at 8 th week of age. The 8 th week cumulative FCR was 3.23±0.15. At 6 th week of age, all recorded linear body measurements were higher in male chicks than the female chicks except body girth. At 8 th week of age, body girth, shank length, shank width and head width were significantly (P≤0.05) higher in male chicks than that of female chicks. From this study, it was concluded that the Native × CSF...

At the end of growing period, the remaining female birds in each system were observed and recorded for egg production from date of first lay up to 40 weeks of age and egg quality traits were recorded at 40th week. The data revealed that birds under semi-intensive system had significantly lower age at sexual maturity as compared to their intensive counterparts while the reverse was true for egg production. It was also observed that the rearing systems had significant effect on different egg quality traits like egg weight, albumen index, yolk index and Haugh unit. The egg quality traits of crosses under study are desirable for handling pressure of traditional rural farming practices.

The eggs were collected form 548 progenies (1 egg from each progeny) of 282 dams mated to 47 sires of a White Leghorn flock at Central Poultry Development Organization (CPDO), Eastern Region, Bhubaneswar, Government of India. Full-sib method of analysis was adopted to estimate the existing genetic correlations among different egg quality traits. Egg weight was found to have statistically significant (p<0.01), positive genetic correlations with shell weight (0.73), albumen weight (0.73), yolk weight (0.68), yolk height (0.51), yolk diameter (0.46) and yolk index (0.42). It was also determined that most of the internal quality traits of the egg changed at statistically significant levels (p<0.01) according to the changes in egg weight and egg breadth. Our studies show that if selection for albumen height will be operated, it will positively affect to internal and external traits whereas shape index will be affected negatively (−0.52±0.14). It is feasible to formulate an index selection depending upon the magnitude of correlations between different quality traits for improvement of more than one traits at a time.
