Abstract
The present study was planned for genetic studies on various economic traits of two strains of white leghorn chicken. The experiment was carried out in 12th and 22nd generations of Anand Bantamized White Leghorn (ABWLH) and Anand Synthetic White Leghorn (ASWLH) strains of White Leghorn, respectively, at Poultry Research Station, College of Veterinary Science and Animal Husbandry, Anand Agricultural University, Anand. At 16 weeks of age 372 and 340 pullets of ABWLH and ASWLH strains were housed in Individual California Cage System for recording individual performance, out of which 357 ABWLH and 324 ASWLH pullets have been contributed up to 40 weeks of age. The liveability of ABWLH and ASWLH strains were recorded 95.97 and 95.29 percent, respectively. Various traits like body weight (BW) at day old, 4, 8, 12, 16, 20, 28 and 40 weeks of age, age at first egg (AFE), total egg number produced upto 40 weeks of age (TEN40), egg weight (EW) at 24, 28, 32, 36 and 40 weeks of age and total egg mass produced upto 40 weeks of age (TEM40) were measured and utilized for estimation of least square mean and standard error, heritability and genetic and phenotypic correlations.
