THE PHILIPPINE WATER BUFFALO

1645.37. Considering the high test of significance, strong
correlation, reasonable accuracy, ease and handiness of
this method, it could be great value in field diagnosis if
adopted in the Philippine setting.

THE ERYTHROCYTE SEDIMENTATION RATE AND
PACKED CELL VOLUME OF BLOOD OF PHILIPPINE
CARABAOS*

The erythrocyte sedimentation rate (ESR) and packed cell
volume (PCV) of 10 female and 10 male carabaos were
measured. The average ESR in males was 70.0 ± 0.7 mm
per hour, and in females 75.3 ± 0.79 mm per hour. The mean
PCV of males and of females were 30.9 ± 0.52 percent and
32.1 ± 0.67 percent, respectively. The difference between
the values for male and female were not statistically significant.

DETERMINATION OF SERUM BILIRUBIN VALUES
OF MATURE CROSSBRED (Swamp X Murrah)
BUFFALOES*
J. M. Espiritu, Student
Twenty (20) apparently healthy, crossbred (Swamp X
Murrah) buffaloes, aging 15-20 months were used in the
study. Serum was obtained from the morning and afternoon
collection. Duplicate serum samples were analyzed
individually in two dilutions applying the van den Bergh
test for bilirubin determination. Test revealed that the time of
collection had no significant effect on the serum bilirubin
level. It was determined that the normal range of direct
bilirubin is 0 - 0.34 mg/dl; 0 - 0.30 mg/dl for indirect and 0
– 0.41 mg/dl for total bilirubin with a normal value of 0.063
mg/dl; 0.107 mg/dl; and 0.168 mg/dl for the direct, indirect
and total bilirubin, respectively.

ESTRUS SYNCHRONIZATION OF CARACOWS AND
CARAHEIFERS USING PROSTAGLANDIN UNDER
STA. MARIA, BULACAN FIELD CONDITIONS*
C. R. Heruela, Student
A study in the synchronization of estrus of Philippine upgraded
buffaloes using an analogue of PGF 2 alpha was done. Of the
22 experimental animals given double injections at 11 days
interval only 14 (63.6%) had estrus three days after the
second administration; five (22.7%) had estrus on the fourth
day; and two (9.09%) had estrus seven days after the
second administration. One had estrus eleven days yet
after the first injection. The present study had demonstrated
that estrus can occur on the third day after the second
administration of Dinoprost tromethamine. Likewise, this study
revealed that 25 mg (5 ml) Dinoprost tromethamine given
intramuscularly and repeated after eleven days was effective
in synchronizing estrus in Philippine upgraded buffaloes.
Estrus detection in caracows and caraheifers was difficult
due to mild external sign. Aside from their having heat at
night, the vagueness of estrus signs necessitates continuous
and close observation of these animals. This could be
overcome by the traditional practice of allowing teaser or
vasectomized carabulls to go along with the caracows and
caraheifers to determine whether they were in heat or not
should artificial insemination be employed. The advantage of
this treatment was that the farmer would be able to calendar
his farm activities by controlling the oestrus cycle since this
drug works by “re-setting” the timing of the estrus cycle.
Based on the results of the present findings, it appears that
PGF 2 alpha could also have a promising use on upgraded
caracows and caraheifers as an oestrus synchronizer and
inducer. This study dealt with estrus synchronization only.
The author therefore recommends a further or follow-up study
to determine the fertility and conception rate of the
synchronized Philippine upgraded caracows and caraheifers,
and the hormonal pattern involved in it.
