Abstract
Genetic aspects of performance Efficiency Index (PEI) and its component traits at different stages of production were studied using performance data from 273 pedigreed pullets belonging to 19 sire families of M line WLH birds. The traits studied included PEI and its component traits viz., percentage egg production (%P), egg weight (EW), body weight (BW) and daily feed cosumption/bird (FC/Day) as well as age at first egg (AFE), body weight at 20 (BW20), 40 (BW40) and 72 weeks of age (BW72), egg number upto 40 (EN21-40) and 72 weeks of age (BW72), egg number upto 40 (EN21-40) and 72 weeks of age (EN21-72), egg weight at 40(EW40) and 72 weeks of age (EM21-72), cumulative feed consumption/bird upto 40 (FC21-40) and 72 weeks of age (FC21-72), daily feed consumption/bird at 40 (FC/Day 21-40) and 72 weeks of age (FC/DE21-40) and 72 weeks of age (FC/DE21-72), feed consumption/kilo of eggs at 40 (FC/KE21-40) and 72 weeks of age (FC/KE21-72).
