THE PHILIPPINE WATER BUFFALO

appearance to the fungiform papillae except for the larger
size and a slightly convex surface. The esophageal mucosal
surface showed longitudinal ridges and furrows and irregular
corrugations. Stratified squamous keratinizing epithelium
in various states of dequamation was observed lining the
esophageal mucosa. Scanning election microscopy
allowed detection of some features on the mucosal surface
of the tongue and esophagus that would have been missed
in light microscopy. The general appearance of the
esophagus and the tongue papillae of the carabao conform
to their counterparts in other species of animal.

A PRELIMINARY STUDY OF THE VASCULAR
ANATOMY OF THE THORACIC LIMBS OF THE
PHILIPPINE BUFFALO (CARABAO) (Bubalus
bubalis)*
M. S. Quinto, Student
A preliminary study of the vascular anatomy of the thoracic
limb of the Philippine buffalo (carabao) (Bubalus bubalis)
was conducted and the results are herein presented. Results
of the dissection of 5 pairs of thoracic limbs showed that the
general pattern of the vascular anatomy of the thoracic limb
of the Philippine buffalo does not differ markedly from that of
the ox. For more conclusive knowledge of the carabao’s
vascular anatomy of the thoracic limbs of the Philippine
carabao, more specimens should be examined.

Measurement of 160 female reproductive organs from
slaughtered non-pregnant Philippine swamp buffaloes with
ANATOMY
age range of 10-15 years and live weight of 280 to 615 kg
was conducted. The average measurements obtained
were: vagina: length – 22.98 + 4.06 cm, width – 6.14 +
1.61 cm; cervix: length – 5.15 + 0.80 cm, width – 4.27 +
0.7 cm, number of cervical folds – 3.60 + 0.66; body of the
uterus: length – 5.07 + 0.63 cm, width – 4.71 + 0.73 cm;
horns of the uterus: length – 21.68 + 4.47 cm; ovary:
length – 2.44 + 0.54 cm; width – 1.62 + 0.40 cm; thickness
– 1.07 + 0.24 cm; weight – 3.03 + 1.18 gm. There was no
statistical difference between paired structures of the female
Philippine swamp buffalo genitalia. This study is only
limited to Philippine swamp buffalo whose age is ranging
from 10 to 15 years.

BIOMETRY, HISTOLOGY AND HISTOCHEMISTRY
OF THE PITUITARY GLAND OF THE PHILIPPINE
CARABAO (Bubalus bubalis L.) AND PHILIPPINE
MURRAH CROSSBRED*
L. Mendoza-Rigos, Assistant Professor, College of Veterinary Science
and Medicine, Central Luzon State University, Muñoz, Nueva Ecija
Pituitary glands from 7 male Philippine carabao (PC), 7
non-pregnant Philippine carabao, 7 pregnant Philippine
carabao and 7 male Philippine Murrah crossbred (PMC)
were used in the study. The weight and size of the pituitary
gland did not vary among the three groups of Philippine
carabao. However, the pituitary glands were heavier and
larger in the Philippine carabao than in the Philippine Murrah
crossbreds. Histologically, the pituitary gland in the
Philippine carabao and the Philippine Murrah crossbred
was surrounded by dense
white fibrous connective tissue capsule which was thicker
at the dorsal surface of the gland; a highly vascular basophilic
zone of pars distalis; partial or complete ensheating of pars
nervosa by the pars intermedia; marked lobulation of pars
intermedia, with each lobule bounded by simple columnar
to pseudostratified columnar epithelium; presence of “wheellike”
bodies in pars intermedia; clear demarcation of pars
intermedia from pars distalis by a thin layer of collagen
fibers and from pars nervosa by a thin layer of loose
connective tissue; absence of cone of Wülzen in the pars
intermedia; and the colloid-filled hypophyseal cleft which
was lined by simple cuboidal to squamous epithelium. In
