Genetic characterization of half-sib mating on growth and production traits in White Leghorn population

The genetic and phenotypic parameters involving body weight at 4, 8, 12. 16 and 20 weeks, age at sexual maturity and 90-days egg production were recorded. The mean of traits were 168.02±1.78, 374.98±4.16, 654.47±5.88. 880.02±7.73. 1161.90±9.50 (gm.). 188.99±0.62 (days) and 38.11±0.27 (No.), respectively. The heritability for their traits were 0.15±0.11. 0.16±0.12. 0.14±0.11. 0.22±0.13, 0.22±0.13. 0.17±0.12 and 0.34±0.16 respectively. The genotypic and phenotypic correlations were mostly significant and positive.
