Abstract

On gross examination of 308 fresh female bovine genital tracts abnormalities which involved the oviducts were adhesions (20.5%), paratubal cysts (4.87%) and hydrosalpinx (1.62%). One hundred and eighty of these were studied in more detail and in 3 both oviducts were blocked whereas unilateral blockage was found in 6. Insufflation studies on apparently normal tracts showed a wide variation of pressures at which air escaped from the oviducts. The main area of resistance to the passage of air was the isthmus. Endometrial rupture occurred in 31% of the tracts during transuterine insufflation of the oviducts although in 98% of these both oviducts were patent. Subsequent passage of air down the oviducts required significantly higher pressures. The phenosulphonphthalein dye test was studied to determine its clinical application in cattle. This involved instillation of the dye into the body of the uterus via the cervix and detecting its passage through the oviducts into the peritoneum by its presence in the urine. When the dye was detected within 15-30 minutes both oviducts were patent. The stage of the oestrous cycle did not have any obvious effects on the test. In some cases with delay in appearance of the dye in urine, on repeating the test two or three times there was a reduction in the time of appearance of the dye. If after 3 tests the dye did not appear in the urine until about 45-60 minutes, one oviduct was occluded and if it was not detected by 120 minutes, both oviducts were occluded, these findings being confirmed both on post-mortem examination and by carrying out oviduct ligation in 2 animals. The test did not cause obvious damage to the epithelium lining of the uterus or oviducts and resulted in an almost complete emptying of oviduct lumenal contents. The carcase value was not lowered and the future fertility did not appear to be reduced since 4 of the 5 animals which were Inseminated conceived to first insemination and were all diagnosed pregnant at 2 1/2 months. Endoscopy demonstrated that the dye passed through the oviducts. In most cases the entire genital tract could be seen from either left or right flank, the latter being an easier method with better visualisation. In fat animals both left and right flank approaches were necessary for complete visualisation.
