Alberto A. Taveros | Agnes M. Taveros | Oscar B . Posas

 

Abstract:

Bimonthly visits were made to different barangays of Baybay, Albuera and Inopacan, Leyte. Caracows which were naturally in heat were inseminated while the others were artificially induced using prostaglandin F,a and subsequently inseminated. It was observed that during the full phase of the moon, 85.90% of the caracows were naturally in heat while all (100%) of the artificially induced animals came into heat after injection with the hormone.
