Abstract

Effect of selection for increasing four weeks body weight and estimation of genetic parameters of body weight in Japanese quails was investigated. Data from selected and control lines were collected three generations. The genetic gain of four weeks body weight was 21.68 and 19.84 g for first and second generation; respectively with overall genetic improvement was 41.52 g in selected line. The corresponding values in control line,  was 16.50,  13.30, and  29.80 g; respectively. There was significant effect of sex, generation, and lines (P < 0.05). Realized heritability was 0.97, 0.94 in first, and second generations. However, the expected heritability using pedigree information was 0.45 and 0.41. The genetic and phenotypic correlations of body weight at different ages were variable and ranged from 0.09 to 0.68. Selection for four weeks body weights improved body weight
