| Abstract/Description: | his study aimed to assess the impact of non-genetic and genetic factors on growth and layer economic traits. Genetic and phenotypic parameters were also estimated for layer economic traits in Rhode Island Red (RIR) breeds. Records of chicken were collected from the Experimental Layer Farm of the Institute (CARI, Izatnagar). The estimated least square means for age at sexual maturity (ASM), Body weight at 20 and 40 week of age (BW20 & BW40), egg weight at 28 and 40 weeks of age (EW28 & EW40) and egg production at 40 week of age (EP40) were found as 186.37±1.67 days, 1517.69±0.40 g, 1783.43±0.73 g, 41.69±00.29g, 48.87±00.21 g and 51.06±1.33egg, respectively. Sire had a significant (P≤0.05) influence on ASM, BW20 and EW40 and hatch showed nonsignificant effect on all traits except EP40. The highest estimates were observed in 2nd hatch for all layer economic traits but the lowest estimates were for growth traits. Birds born in the first hatch were heavier than those of second hatch due to differences in nutrition, and management in the various hatches. Low heritability was estimated for EP40 and BW40 while ASM and BW20 were moderately heritable. |
