Abstract
The aim of this study was to determine the morphology and morphometry of the reproductive organs of Aceh cows that experience the repeat breeding (RB). This study used samples of reproductive organs from RB and non-RB (fertile) Aceh cows, each of three cows with body weights of 150-200 kg and aged 3-6 years. Samples were obtained from a local slaughterhouse, including the ovarium, oviduct, cornua, corpus, and cervix uteri, vagina, and vulva. The criteria of RB and fertile Aceh cows were obtained from inseminators reports. Morphological and morphometric observations were performed on ovaries, oviduct, cornua, corpus, and cervix uteri, vagina, and vulva. The results showed that morphologically there were observed differences in ovaries of RB cows namely the presence of ovarian cysts and swelling in cornua uteri that accompanied by pyometra and hydrometra, and also deformation of cervix uteri. According to morphometric observation, the diameter of cornua uteri dexter, cervix uteri, and vulva of RB cows was bigger than non-RB cows (P<0.05). It can be concluded that morphology and morphometry of reproductive organs of RB and non-RB Aceh cows are different except for the oviduct.
