AR. Guimaraes GC., Unilateral agenesis of uterine
horn in swine – case report, Onl J Vet Res., 22
(4):300-303, 2018. Congenital anomalies of the uterus in pigs are
uncommon. Among these, there is unilateral uterine horn agenesis, defined as an
alteration of the fetal formation that results in the non-development of the
paramesonephric or Müller ducts. It is associated with recessive genes and is
considered a hereditary alteration. The objective of this work was to report a
case of unilateral uterine horn agenesis in pigs resulting from crossbreeding
between the Landrace and Large White breeds. The absence of a uterine horn in
pigs does not make the animal infertile, contrary to what may occur in cattle,
but with the presence of only one horn the number of piglets born is smaller,
thus jeopardizing the reproductive efficiency of the female.
