Six mature and healthy Philippine carabaos (PC) were<br />
selected after having shown normal estrus cycles for three<br />
consecutive times. All animals were fed in confinement<br />
and were fasted for at least 6 hours prior to actual ovarian<br />
observations. A simple fiberscope (FS-100, Scott Fiber<br />
Optics, Inc., MA USA) was inserted through a puncture<br />
on the vaginal floor following administration of anesthetics<br />
at the sacro-lumbar region. Observations of ovarian<br />
structures were done every 3 days throughout the estrous<br />
cycle using the same route. Using the simple fiberscope,<br />
surface follicles 3.0 mm and corpus luteum (CL) were<br />
observed. There was no alteration in the duration of the<br />
length of the estrous cycle associated with repeated<br />
observations. The procedure allowed observation of<br />
follicular changes throughout the cycle and permitted direct<br />
observation of changes in the ovary related to ovulation.<br />

Bimonthly visits were made to different barangays of<br />
Baybay, Albuera and Inopacan, Leyte. Caracows, which<br />
were naturally in heat were inseminated while the others<br />
were artificially induced using prostaglandin F 2 alpha and<br />
subsequently inseminated. It was observed that during<br />
the full phase of the moon, 85.90% of the caracows were<br />
naturally in heat while all (100%) of the artificially induced<br />
animals came into heat after injection with the hormone.<br />
Keywords: caracows, farmers’ perception of occurrence<br />
of estrus<br />

Seven purebred Murrah buffalo (MB) cows with average<br />
age of 10 years and live weight were used to determine<br />
the possibility of utilizing Philippine carabao (PC) as<br />
recipients of MB embryos. All MB cows (donors) were<br />
treated with a total of 44 mg follicle stimulating hormone,<br />
porcine (pFSH) initiated on day 9 in declining dose of 7.7<br />
mg, 6.6 mg, 8.5 mg and 4.4 mg on days 9, 10, 11 and<br />
12, respectively. Serial administration of pFSH were<br />
done at 12 hours interval prostaglandin F 2 alpha (PGF 2<br />
alpha) were given to all animals 60 and 72 hours after the<br />
initial pFSH treatment. Inseminations were made 12 and<br />
24 hours after onset of estrus. All PC (recipients) were<br />
treated with PGF 2 alpha 12 hours ahead of the donor<br />
animals. Animals with good corpus luteum (CL) on day<br />
5 were selected and were used as recipient. Embryos<br />
were collected nonsurgically from donor animals on day<br />
5 ½ and were all transferred on the same day. Average<br />
number of ovulation in donor animals was 2.86 + 1.87<br />
and the average number of unovulated follicles was 2.2<br />
+ 1.79. Average recovery rate of embryo was 70%<br />
with 71.36 recovery of the flushing medium. Four of 14<br />
embryos collected from MB were of good quality and<br />
one of three embryos transferred to PC recipients resulted<br />
to successful pregnancy.<br />
