deworming period and the post-deworming period. An
eosinophil count of 20.7% in the morning and 24.04% in
the afternoon of the first day of the pre-deworming collection
were recorded. An eosinophil count of 18.4% and 24.3%
in the morning and afternoon, respectively were recorded
for the second day of collection. The animals during these
periods of collection were rested and fed on a cut and carry
basis or pastured as compared to post deworming collection
wherein these animals were used for draftwork. During the
post deworming period, the eosinophil count of 24.04%
and 26.43% in the morning and afternoon respectively
were recorded. On the second day of collection, 26.67%
in the morning and 26.74% in the afternoon were recorded.
During the pre deworming period, 257.7 EPG was recorded
and 132 EPG was recorded during the post deworming
period.

A STUDY ON THE BLOOD GLUCOSE LEVELS OF
ADULT CARABAOS (Bubalus bubalis)*
A. S. Sol, Student
One hundred (100) healthy swamp buffaloes, 50 male and
50 female, with age ranging from 5-12 years were used in
the study. Serum samples were obtained early in the
morning and analyzed for blood glucose level using 0toluidine,
Dubowski Modified Method. Test revealed that
there was a slight sex variation in the blood glucose level
of the animals with an average of 38.67 mg/dl and 34.73
mg/dl for male and female animals, respectively. Seventy
percent of the animals studied had a glucose level of less
than 44.76 mg/dl for males and less than 40.31 mg/dl for
female carabaos.

A STUDY ON THE CONCENTRATION OF SOME
SERUM ELECTROLYTES IN PHILIPPINE
CARABAOS (Bubalus bubalis)*

A study was undertaken to determine the concentration of
some serum electrolytes in 120 Philippine carabaos. The

THE PHILIPPINE WATER BUFFALO
serum sodium concentration ranged from 120.50 to 283.00
mEq/L with mean (± SD) of 200.20 ± 35.20 mEq/L. The
values fell within a wider range than those given for normal
values in other domestic ruminants. Serum potassium
concentration ranged from 3.00 to 7.65 mEq/L with mean
(± SD) of 4.78 to 0.67 mEq/L. These values did not vary
considerably from the results of other studies made in
different ruminants. Serum calcium determination in 120
animals yielded a range of 7.80 to 14.00 mg/dl and a mean
(± SD) of 3.16 ± 1.58 mg/dl. The present data were within
the range of normal values given for other domestic
ruminants. A mean of 3.16 ± 1.58 for magnesium and
164.84 ± 56.24 for zinc was obtained. The range varies
from 0.84 to 11.50 for magnesium, 107.00 to 485.00 ìg/dl
for zinc. Data from the present study for serum magnesium
and zinc were within a wider range of normal values for
other domestic animals. There was no statistical significant
difference found between male and female for all the
electrolytes determined. Serum sodium concentrations
appeared higher in the morning and gradually decreased in
the afternoon and further at night (Z = 1.32; 5.62; 3.34).
Calcium concentration decreased with increasing age (Z +
4.56). The limitation of the present study involved limited
samples and lack of more extensive data that could be
used for greater correlation of the different factors.

HEMATOLOGICAL STUDY OF YOUNG PHILIPPINE
SWAMP BUFFALO (Bubalus bubalis L.): RBC
MORPHOLOGY, RBC COUNT, PCV, Hb, ESR, MCV,
MCH AND MCHC*
M. E. M. Tan, Student
Hematological indices such as RBC morphology, count,
hemoglobin (Hb), erythrocyte sedimentation rate (ESR),
packed cell volume (PCV), mean corpuscular volume
(MCV), mean corpuscular hemoglobin (MCH) and mean
corpuscular hemoglobin concentration (MCHC) were
determined from blood samples of 60 apparently normal
Philippine swamp buffaloes (30 males, 30 females) from
different barangays of Nueva Ecija. Sample animals were
classified into 3 age groups; each group was composed of
20 experimental animals in equal sex ratio of 10 males and
10 females. The age of animals under group I ranged from
1 to 12 months. Group II comprised of carabaos whose
age varied from 13 months to 24 months, and group III
represented the adult buffaloes with ages ranging from 25
