dc.description.abstractThis study was designed to assess the reproductive performance of Neospora caninum–infected dairy cows (Bos taurus) after abortion. The population examined was composed of 92 aborting cows subsequently subjected to at least one artificial insemination (AI) attempt. Of these animals, 68 were N. caninum seropositive and 24 were seronegative. Only animals producing at least 25 kg milk at the estrus after abortion were inseminated. Normal uterine involution was verified at first AI after abortion in cows showing estrous signs within 30 d of abortion. Of the 92 aborting cows, 73 (79.3%) became pregnant after abortion: 57 (83.8%) and 16 (66.7%) of the N. caninumseropositive and seronegative cows, respectively. The factors days of gestation and lactation number at abortion failed to differ between the two Neospora serostatus groups, based on Student’st-test or Kruskal-Wallis tests, respectively. The interval from abortion to first AI, the number of AIs necessary for an animal to become pregnant, and the interval from abortion to next pregnancy in cows becoming pregnant were lower for the N. caninum–seropositive than for the N. caninum–seronegative cows (P < 0.0001). Logistic regression analysis indicated no significant effects of herd, lactation number, days of gestation at abortion, and the interval from abortion to AI on the likelihood of pregnancy at first AI after abortion. Based on the odds ratio, Neospora-seropositive cows were 6.22 times more likely to become pregnant at first AI after abortion compared with their seronegative partners. Fifty-three of the Neosporaseropositive cows (78%) were inseminated within 30 d after abortion and 26 (49%) became pregnant, whereas only one seronegative cow (4.2%) was ready for insemination within this 30-d period and remained open after first AI. These results indicate that Neosporainfected cows suffering abortion can be inseminated with a likelihood of high fertility within the first month of abortion. We recommend checking that uterine involution is normal early after abortion in N. caninum–seropositive cows.ca_ES
