Comparison of Intrauterine Antibiotics versus Ozone Medical Use in Sheep with Retained Placenta and Following Obstetric Assistance.
    Reproduction in domestic animals = Zuchthygiene, 2016, Volume: 51, Issue:4

    This study outlines a new approach to reproductive tract treatment using ozone foam spray for certain ovine obstetrical problems, such as retained foetal membranes and possible uterine infections following obstetric assistance (OA), in comparison with classical antibiotics treatments. The study was conducted on 256 ewes from 11 sheep farms in north-western Croatia. A total of 139 ewes were diagnosed with dystocia (DT) and 49 with retention of placenta (RP). Ewes with RP were treated either with ozone foam spray (Riger spray G; Novagen(®) ) applied into the body of the uterus for 2-3 s (first or RPO group; n = 24) or with two foaming, intrauterine tablets of oxytetracycline hydrochloride (Geomycin(®) F) (second or RPA group; n = 25). The third and fourth groups consisted of ewes that received OA for dystocia (including ringwomb, foetal oversize and assistance of abnormal position and posture). The third group (DTO; n = 70) was treated with ozone foam spray, while ewes in fourth group (DTA; n = 69) were treated with antibiotics. The ewes in the control group (CTL) with physiological puerperium were randomly selected (n = 70) from all herds. Transrectal ultrasonography (transversal diameter of uterine horns) was used for the control of uterus regression on days 2 and 25 after parturition. There was a difference in transversal uterine horn diameter in the RP groups, that is RPO and RPA (5.40 ± 0.53 cm vs. 5.43 ± 0.40 cm), ewes with dystocia, that is DTO and DTA (5.37 ± 0.49 cm vs. 5.54 ± 0.60 cm) and ewes from the CTL group (4.98 ± 0.35 cm) one day after parturition. Average transversal uterine diameter of all groups at day 25 post-partum was 1.80 ± 0.15 cm. The intrauterine ozone treatment in ewes with RP and after manual obstetrics attained similar results to spontaneously delivered ewes (CTL group), showed as the physiological regression of the uterus with a similar transversal diameter without the presence of lochia in the uterine lumen, indicating that this could be a novel potential alternative therapy.

15-Ketodihydro-PGF(2 alpha), progesterone and uterine involution in primiparous cows with induced retained placenta and post-partal endometritis treated with oxytetracycline and flunixin.
    Reproduction in domestic animals = Zuchthygiene, 2002, Volume: 37, Issue:1

    Retention of the foetal membranes (RFM) and post-partal endometritis are common problems in dairy cows. Among other things, the disease is characterized by a bacterial endometritis with aerobic as well as anaerobic bacteria. From an endocrine perspective, cows with RFM have high levels of 15-ketodihydro-PGF(2 alpha) (PG-metabolite) immediately after parturition but these levels fall rapidly within 2 weeks post-partum (early PG-metabolite elevation). After this decline, the PG-metabolite levels increase again and the levels (at this time of a lower magnitude) remain elevated during the period of uterine infection (late PG-metabolite elevation). The aim of this study was to investigate the PG-metabolite profiles in cows with retained placenta and post-partal endometritis treated with the prostaglandin synthesis inhibitor flunixin (F), either alone or in combination with oxytetracycline (T). The study was accomplished over 2 years with 12 primiparous cows in each experiment. As a model for RFM, preterm parturition was induced in late-pregnant heifers by injecting PGF(2 alpha) (25 mg i.m) twice with a 24 h interval. In each experiment, the cows were divided into four groups and treated with either T (10 mg/kg b.w. i.m. once daily), F (2.2 mg/kg b.w. p.o. twice per day), a combination of T and F (dosage, as above), or conservatively (0). The treatment periods lasted from day 11 to day 14 post-partum (pp) in experiment 1 (after placental shedding, groups T1, F1, TF1 and 0) and from day 3 to day 6 pp in experiment 2 (before placental shedding, groups T2, F2, TF2 and 0). Jugular vein blood samples were collected for analyses of PG-metabolite and flunixin. Uterine biopsies were collected twice weekly for investigation of endometrial microbiology. Rectal palpation and ultrasonographic examinations were performed three times per week for investigations of uterine and cervical involution and ovarian activity. No attempts were made to remove the placentas manually. The experiment lasted until day 56 pp. The induction of parturition was successful in all heifers and 22 of 24 animals had RFM. All RFM cows had bacterial endometritis, based on bacteriological examinations. Flunixin treatment (F1, TF1, F2 and TF2) suppressed PG-metabolite levels significantly (p=0.006) during the period of treatment in both experiments. However, the early flunixin treatment only suppressed PG synthesis partially. Late oxytetracycline treatment (T1) did not influence the PG-metabolite level

Clinical and bacteriological aspects on the use of oxytetracycline and flunixin in primiparous cows with induced retained placenta and post-partal endometritis.
    Reproduction in domestic animals = Zuchthygiene, 2001, Volume: 36, Issue:5

    Retention of the fetal membranes and post-partal endometritis (RFM) are common problems in dairy cows. Treatment often includes manual removal of the placenta in combination with antibiotic treatment. Earlier studies have shown that cows with endometritis post-partum have a strong tendency to recover spontaneously. The present study focused on treatments of post-partal endometritis with the prostaglandin synthesis inhibitor, flunixin (F) either alone or combined with oxytetracycline (T). The study was conducted in two experiments, using 12 primiparous cows in each. As a model for RFM, premature parturition was induced in late pregnant heifers by injecting PGF2alpha (25 mg i.m.) twice with a 24 h interval. In each experiment the cows were set into four groups and treated with either T (10 mg/kg BW i.m. once daily), F (2.2 mg/kg BW p.o. twice daily), a combination of T and F (dosage, as above) or conservatively (group 0, no drugs). The treatment periods lasted from days 11-14 post-partum in experiment I (groups T1, F1, TF1 and 0) and from days 3-6 post-partum in experiment 2 (groups T2, F2, TF2 and 0). Jugular vein blood samples were collected for analyses of flunixin and total white blood cells. Uterine biopsies were collected twice weekly for investigation of endometrial microbiology. Rectal palpation and ultrasonographic examinations were performed three times weekly for investigations of uterine involution and ovarian activity. No attempts were made to remove the placentas manually. The experiment lasted until day 56 post-partum. The induction of parturition was successful in all heifers and 22 of 24 animals had RFM. All RFM cows had bacterial endometritis. The predominant bacteria were Escherichia coli alpha-haemolytic streptococci, Fusobacterium necrophorum, Arcanobacterium (Actinomyces) pyogenes, Bacteroides spp., Pasteurella spp. and Proteus spp. Fusobacterium necrophorum and A. pyogenes could be isolated for 3-5 weeks post-partum and E. coli Pasteurella and Proteus could be isolated for 2-3 weeks post-partum. Animals treated with tetracycline after placental shedding (T1 and TF1) had a more rapid recovery from infections with A. pyogenes and F. necrophorum than animals that were not treated with tetracycline. No other genera were affected. Antibiotic treatment before placental shedding (T2 and TF2) did not shorten the uterine infection but altered the bacterial flora, seen as an overgrowth of Proteus spp. (p < 0.05) and increased frequency of Paste

Evaluation of injections of collagenase and oxytetracycline via the umbilical artery as treatment for retained placenta in cattle.
    American journal of veterinary research, 1996, Volume: 57, Issue:4

    To test whether oxytetracycline inactivates collagenase when combined as a potential treatment for retained fetal membranes in cattle and to determine whether oxytetracycline passes to blood from fetal membranes after intraplacental injection.. Prospective, controlled study.. 288 placentomes from 12 cows in their third trimester of pregnancy and 4 cows at term pregnancy.. 8 experimental groups were established: saline control, collagenase, collagenase plus oxytetracycline at 3 dosages, and oxytetracycline at 3 dosages. Placentomes were infused through an umbilical vessel with the test solutions and incubated at 39 C for 4 hours. Immediately after incubation, the force needed to detach cotyledons from caruncles was measured by a manometric technique. Cotyledon-caruncle interface fluids were analyzed for hydroxyproline (collagen breakdown) and total protein contents. A combination of collagenase and oxytetracycline was injected via umbilical arteries of cows undergoing cesarean section and in cows with retained fetal membranes after natural delivery. Antibiotic residue in blood was determined by the Bacillus stearothermophilus disk assay.. There were no significant differences among collagenase and collagenase plus oxytetracycline groups in the amount of pressure needed to separate cotyledon from caruncle, amount of hydroxyproline released, and amount of total protein broken down. The 4 cows tested negative for oxytetracycline in the blood.. Oxytetracycline and collagenase may be a potential combination treatment for retained fetal membranes in cattle. In addition, the lack of antibiotic residue detection in blood may be of regulatory relevance.

Evaluation of the use of intrauterine infusions of oxytetracycline, subcutaneous injections of fenprostalene, or a combination of both, for the treatment of retained fetal membranes in dairy cows.
    Journal of the American Veterinary Medical Association, 1995, Dec-15, Volume: 207, Issue:12

    Dairy cows (n = 207) that had retained fetal membranes for more than 8 hours after parturition were randomly assigned to 1 of 4 treatment groups (group 1, daily intrauterine infusion of oxytetracycline; group 2, daily intrauterine infusion of oxytetracycline and a single SC injection of fenprostalene; group 3, a single SC injection of fenprostalene; and group 4, untreated controls). Cows were monitored daily. Subsequent disease conditions were recorded, and appropriate treatments were initiated. Interval from parturition to expulsion of fetal membranes was unaffected by treatment regimen. The frequency of cows with high rectal temperatures (> or = 39.5 C) was significantly (P < 0.05) less in cows treated with oxytetracycline infusions; however, the frequency of displaced abomasum, ketosis, and mastitis was unaffected by treatment method. Treatment method appeared to influence the development of postpartum uterine pathologic conditions. Treatment with oxytetracycline and fenprostalene (group 2) increased (P < 0.05) the frequency of pyometra. Treatment with fenprostalene (groups 2 and 3) decreased the number of cows with a palpable uterine lumen detectable during per rectal palpation at 28 to 42 days after parturition. Reproductive efficiency, as determined on the basis of the interval from parturition to conception, was unaffected by treatment protocol.

Oxytetracycline residues in milk after intrauterine treatment of cows with retained fetal membranes.
    Journal of the American Veterinary Medical Association, 1996, Nov-15, Volume: 209, Issue:10

    To establish the maximum concentration and duration of oxytetracycline residues in milk from cows with retained fetal membranes given the antimicrobial via intrauterine infusion, and to investigate whether the number of infusions or the presence of fever (> 39.7 C) affected the duration of residues.. Prospective study.. 54 Holstein cows with retained fetal membranes on a single 1,400-cow commercial dairy.. Cows were treated once a day with 5 g of oxytetracycline (50 ml of 100 mg/ml solution in a povidone base) by intrauterine infusion for at least 2 days, or until the membranes were expelled. Cows that became febrile (rectal temperature > or = 39.7 C) were also given 20,000 IU of procaine penicillin G/kg of body weight, i.m., for 2 to 4 days. Milk samples were collected at 24-hour intervals during treatment. and at 12-hour intervals after the last treatment. All samples were frozen and submitted every 2 weeks for high performance liquid chromatography analysis for oxytetracycline.. Oxytetracycline was detected in milk of all cows during treatment, at a maximum concentration ranging from 47.2 to 1,804.6 micrograms/kg (mean, 316.9 micrograms/kg). Duration of oxytetracycline residues after the last infusion ranged from 0 to 144 hours (mean, 52.3 hours). Neither the number of infusions received, nor development of rectal temperature > 39.7 C, affected the maximum concentration or the duration of oxytetracycline residues in milk.. Milk obtained from cows that had been treated for retained fetal membranes by intrauterine infusion of oxytetracycline should be discarded to avoid illegal residues.
