Abstract
Gross and microscopic anatomy of the stomach of
twenty adult goats, including blood supply and nerve sup
ply have been investigated. Linear, weight and capacity
measurements were recorded in relation to body length and
weight. The disposition of inner mucosa of various stomach
compartments was also studied.
The caudo-ventral blind sac of rximen of goat, unlike
that of other ruminants, extended more caudally than the
dorsal one. Dorsal coronary grooves were absent. The
right ventral coronary groove was distinct and reached
the ventral border of rumen. The omasum was the smallest
and oval in shape. The a}x>masum was comparatively larger
in goats.
The conpoiand stomach in adult goat weighed 3,45 per
cent of intact body weight. The volume of different
stomach con^artments as percentage of total stomach were
73, 7, 2 and 18 for rumen, reticulxam, omasiim and abomasum
respectively. The wet tissue weights of different compart
ments as percentage of total stomach were about 66, 9, 8
and 17 for rumen, reticuliim, omasum and abomasum respectively.Basically, the mlcrosTOpic structure of goat
stomach resembled closely that of other uruminaats.
The forestomach had the non-glandular cutaneous
mucous membrane, a connective tissue sxib mucosa, a
two layered muscvilar tunic and a serosa. The omasum
and abomasum presented the muscularis raucosae. The
abomasum had glandular epithelium with the cardiac,
fiindic and pyloric regions.
The different con^jartments of stomach of goats
was innervated by the dorsal and ventral branches of
the vagus. The arterial supply was by the branches
of coelic artery.
