Effects of early weaning on small intestine morphometric trait of three segments (duodenum, jejunum and ileum) of squabs of two groups at the age of 25 d. (A) Villus height; (B) crypt depth; (C) villus area; (D) the ratio of villus height to crypt depth (VCR). 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. Values means n = 8 for the analysis of the intestine form. Data are means ± SEM. * means P < 0.05; ** means P < 0.01.
