Abstract: The study highlights on estimate some parameters of the body weight according to low – high body weight of Japanese Quails and investigate the effects of divergent selection on some productive traits and reproductive traits in 3 generations divergently selected Japanese Quail (Coturnix Coturnix Japonica) lines, in the parents (body weight, egg productions, egg weight, egg interior and exterior Qualification) and in the offspring (body weight, feed ratio conversion, increase body weight, carcass, feed consumption selaughter).The traits showed -Growth traits: body weights at (0, 2, 4, 6) weeks of age and average daily gains calculated among different growth periods studied (0-2, 2-4, 46, 0-6) weeks of age. Reproductive and egg production traits: total egg number and weights and daily egg mass produced among the first ten weeks. Carcass traits: meat, bone, giblets and dressing percentages. In addition study genetic parameters of body weight. The moderate to high heritability for most study traits suggested that selection to increase or decrease these traits will be successful. The genetic parameters of body weight at different ages, measurements were positive and tended to be moderate to high. These results showed that selection for weight at early ages will have appositive effect on weight.
