Histological observations on the developing intestine of the bovine fetus.
Histological changes in the samll intestine of 36 bovine fetuses were studied, with particular reference to the villi and intestinal glands. The first evidence of rudimentary villus formation was observed in a fetus estimated to be 30 days old. Crypts of Lieberkühn were noted at 110 days of fetal life. In late gestation and at birth the mucosal structure was fully mature.
