Effects of early weaning on BW (A), ADG (B), and survival rate (C) of squabs in two groups between 7 D and 25 D. BW of early weaning squabs was recorded at the age of 25 and compared with CON group. ADG was calculated by period and expressed as g/d. Rate of survival was calculated as the percentage of alive squabs to total number of squabs in CON group and EW group representatively. CON group: control group; EW group: test group, squabs were fed by parental pigeons for first 6 d after hatching, and then fed by hand. Data represents the mean value for each treatment (8 birds per treatment).
