Morphological Studies of Peyer’s Patches of the Goat (Capra Hircus). I. Gross Changes with Age

Abstract

Gross morphological studies   were performed   on   the   Peyer's   patches of three age groups   of   local   breed   male goats.   Neonatal   kids   had   an   average   or 35 Payer’s patches in the jejunum, two in the colon and a long patch which extended from the jejunum to the ileocecocolic junction (jejuno-ileal Peyer’s patch JIPP). There was no patch in the duodenum. The J IPP atrophied with age.  There was no significant difference (P>0 .05) between the   number or Peyer's patches in the three groups. The proportion of intestine on which the Peyer’s patches extended in both neonatal and three months old kids was significantly higher (P<0.05) than that or 12 months   old goats.  The   JIPP showed morphological similarities to a primary lymphoid organ.
