“…The present investigation adds new information suggesting that ASP does not influence the calving rates and extending knowledge about the subject. It has been reported that early pregnancy diagnosis by ASP during the embryonic period (first 45 days of gestation) [30], especially between 36 and 42 days of gestation, was associated with an increased risk of atresia coli and/or jejuni [31][32][33][34][35]. In the United States, one calf was diagnosed with atresia coli from an investigation with the use of organic phosphate systemic insecticides pour-on [31]; however, these authors mentioned that this abnormality was previously noticed in eight calves from 798 neonatal necropsies covering 15 years from 1963 to 1977 in an experimental station in Montana [41].…”

“…However, in those studies, no information about calving rates or clinical abnormalities of the newborn calves was reported. Studies in the United States and in other areas of the world have observed an association between amniotic sac palpation (ASP) during the embryonic period for pregnancy diagnosis until Day 45 of gestation [30] and an increased risk of atresia coli and/or jejuni in newborn calves [31][32][33][34][35]. In atresia coli and/or jejuni, a section of the large bowel or jejuni is absent, resulting in a blind-ending intestinal tube.…”

“…Atresia coli and/or jejuni has been reported in different countries and in more than 10 breeds of cattle with a marked predominance in Holstein calves [40]. On the basis of those findings, some sources have recommended avoiding PRP of the uterus during the first 45 days of gestation [31][32][33][34][35]41,42]. In spite of this, intestinal atresia was also reported to be inherited as an autosomal recessive trait in Jersey and Swedish Highland cattle [43,44].…”

The objectives of the present study were to evaluate the effect of per rectal amniotic sac palpation (ASP) for pregnancy diagnosis during the late embryonic period on pregnancy loss, calving rates, and abnormalities in newborn calves. A controlled, randomized, blocked, blind experiment containing 680 lactating pregnant dairy cows with a viable embryo diagnosed by transrectal ultrasonography was performed. Two dairy operation sites (farm A and farm B) were selected. At each farm, the cows were randomly divided into control (CON) and ASP groups. The CON group was not subjected to pregnancy diagnosis via per rectum palpation. The ASP examinations were performed by one experienced veterinarian between Days 34 and 45 after breeding. All cows were reevaluated by transrectal ultrasonography only between 2 and 4 weeks later. Two calving rates were calculated: calving rate 1 (cows that calved from the initial number of pregnant cows) and calving rate 2 (cows that calved from cows pregnant at reexamination). In farm A, the percentages of early pregnancy loss were 11.5% (19 of 165) and 13.2% (24 of 182) for the CON and the ASP groups, respectively (P = 0.64). In farm B, the percentage of early pregnancy loss was 11.2% (19 of 170) for the CON group and 8.8% (14 of 159; P = 0.48) for the ASP group. In farm A, the percentage of late pregnancy loss was 7.6% (11 of 145) for the CON group and 5.5% (8 of 155; P = 0.39) for the ASP group. In farm B, the percentage of late pregnancy loss was 3.7% (5 of 137) for the CON group and 6.3% (8 of 127; P = 0.32) for the ASP group. In farm A, early pregnancy loss was higher than late pregnancy loss (12.4% vs. 6.3%; P = 0.01), and in farm B, the same tendency was detected (10.0% vs. 4.9%, for early and late pregnancy loss, respectively; P = 0.02). In farm A, calving rate 1 was 81.2% (134 of 165) for the CON group and 80.8% (147 of 182; P = 0.92) for the ASP group. Calving rate 2 for the same groups was 92.4% (134 of 145) and 94.8% (147 of 155), respectively (P = 0.68). In farm B, calving rate 1 was 77.7% (132 of 170) for the CON group and 74.8% (119 of 159; P = 0.55) for the ASP group. Calving rates 2 for the same groups were 87.4% (132 of 151) and 82.1% (119 of 145), respectively (P = 0.20). Two female calves with atresia coli were diagnosed only in the CON group. It was concluded that ASP during the late embryonic period for pregnancy diagnosis did not increase the pregnancy loss, affect calving rates, or produce abnormalities in calves.

“…Although atresia ani is likely the most common intestinal atresia encountered, atresia coli and atresia jejuni are most represented in the scientific literature. 10 I have diagnosed atresia coli in a variety of beef breeds, including Charolais, Angus, Short Horn, and Polled Hereford. In one report, an incidence rate of 0.76% was reported in a university dairy herd of Holstein cows over a 10-year period.…”

The frequency and location of intestinal malformations and gender distribution of affected calves were investigated. The occurrence of atresia ani/ atresia ani et recti in cross bred or indigenous bred were also studied. Atresia ani with or without other intestinal malformations was diagnosed by the Veterinarian at day 1 (25 calves), day 2 (13 calves), day 3-4 (3 calves) and day 5-8 (2 calves) after birth. The affected calves were reported to have been nursed normally immediately after birth but clinical sign became progressively worse with abdominal distension, loss of appetite and abdominal straining. There was no anal opening, but a bulge appeared at its site. Male calves were more frequently affected with atresia ani than those of female calves. The ratio of the male and female affections was approximately 5: 2. The total percentage of indigenous calves affected with atresia ani was 71.74% and the crossbred were 28.26%. Surgical correction is the only successful technique for atresia ani. The prognosis of surgical correction of atresia ani in calves was found good.
