A study assigning 245 Bulgarian Murrah buffaloes, bred on the Institute’s farm during 1980-2007, was initiated to test the effect of rump measurements and rump indices at 18-month age on the incidence of utero-vaginal prolapse. The data were processed with the conventional statistical procedure by levels of rump length (LR) and width (WR), rump-length index (IRL) and body-balance index (IBB). The effect of IRL on incidence of prolapse was tested using dispersion analyses for qualitative traits, also including the effects of period and season of calving. maxresdefaultThe results indicated that the buffalo cows with prolapse had by 3.1 cm significantly greater LR at 18 months, compared to the normally calved (P< 0.01), WR being practically identical. Prolapse at first parity in particular is associated with even more disproportional rump. The effect of IRL was established to be significant at P< 0.01, the buffaloes with proportionally longest rump having a significantly higher incidence of prolapse (26.0%), compared to the animals with low (8.6%) and moderate (11.5%) index (P< 0.001). Of all 37 prolapsed buffaloes 19 have suffered this obstetrical pathology at first calving, 13 of them having been with the highest value of the index at 18 months. To sum up, it is preferably the Bulgarian Murrah heifers to have more slender body constitution, the difference between the two rump dimentions to be as small as possible, and the rump length – less than 40% of body length.
