Treatment and survival of Norwegian cattle after uterine prolapse.

BACKGROUND: Bovine uterine prolapse is a sporadic but life-threatening postpartum condition. The aims of this study were; (i) to determine which clinical findings determined the likelihood of treatment vs. culling, (ii) to identify the treatment methods currently employed by Norwegian veterinary surgeons and evaluate their effect on survival, (iii) to determine if clinical findings at the time of treatment could be used to determine prognosis. Practicing veterinary surgeons in Norway were contacted and asked to fill out a questionnaire on cases of bovine uterine prolapse they attended between February and October 2012. The questionnaires gathered data on signalment, clinical presentation, treatment, and outcome. These data were supplemented with culling data from the Norwegian Dairy and Beef Herd Recording Systems. The chi-squared test and logistic regression modelling was performed to identify likelihood of treatment and cox proportional hazard modelling was performed to identify the hazard of death after treatment. RESULTS: Data from 126 cases of bovine uterine prolapse were collected (78 beef and 48 dairy cows). Twenty-six cows (21%) were emergency slaughtered, or underwent euthanasia, without treatment. Of the remaining 100 cases amputation of the uterus was performed once and repositioning was performed in 99 cases. Survival data were missing from 2 of the cases that had undergone treatment leaving a study sample of 97 cases (64 beef and 33 dairy cows). Multivariable logistic regression analysis of the explanatory variables showed that beef cows were more likely to be treated than dairy cows (OR = 0.32, 95% CI 0.13 to 0.81, P = 0.017) and that cows with a significantly oedematous or traumatised uterus were less likely to be treated (OR = 0.26, 95% CI 0.10 to 0.67, P = 0.006). Treatment methods amongst Norwegian practitioners were broadly similar. In a multivariable model cows general clinical state at time of treatment was positively correlated with survival (HR = 0.29, 95% CI 0.29 to 0.73, P = 0.008) and a history of a vaginal prolapse prepartum increased the hazard of death (HR = 2.31, 95% CI 1.08 to 4.95, P = 0.031) in the first 30 days after treatment of a uterine prolapse. In the first 180 days after treatment only veterinary assessment of a cows' general clinical state was correlated with hazard of death (HR = 0.432, 95% CI 0.20 to 0.91, P = 0.046). CONCLUSIONS: This study shows that the production system and extent of uterine damage affect the likelihood of treatment, and that practitioners use similar treatment methods. A cows' general clinical state at time of treatment was positively correlated with survival, and a history of a vaginal prolapse prepartum increased the hazard of death in the first 30 days after treatment of a uterine prolapse.

Serum trace mineral variations in Nili-Ravi buffaloes suffering with prepartum vaginal prolapse in two different agro-ecological zones of Punjab, Pakistan.

The present study was conducted during 2005 and 2006 on 200 Nili-Ravi buffaloes kept in two agroecological zones (irrigated [zone 1] and rain-fed [zone-2]) of Punjab, Pakistan, with the objective to determine the level of trace minerals (Cu, Fe, Zn, Se) in serum of the buffaloes suffering from vaginal prolapse and to compare them with their healthy counterparts. In each zone 50 buffaloes suffering from prepartum vaginal prolapse during their seventh month of gestation were identified through survey. Vaginal prolapse-affected buffaloes belonging to zone 1 were identified as group VPB1 (N = 50), whereas buffaloes belonging to zone 2 were recognized as VPB2 (N = 50). The buffaloes of control group in zone 1 and zone 2 were identified as NCB1 and NCB2, respectively. The blood samples in all four groups of buffaloes were collected three times, i.e., first when these animals were in the eighth month of gestation, second during the eighth to ninth month of gestation, and finally when these animals were in the ninth or later month of gestation. The mean serum copper concentrations in buffaloes of group VPB1 were significantly lower (P < 0.05) in comparison with NCB1 and NCB2, whereas there were nonsignificant differences (P > 0.05) in copper concentrations between VPB1 and VPB2. There was a significant difference (P < 0.05) of iron concentration in VPB1 compared with NCB1 and NCB2. Similarly, VPB2 also had significantly lower (P < 0.05) iron concentrations compared with NCB1 and NCB2. Serum zinc concentrations were significantly lower (P < 0.05) in animals of the VPB1 group when compared with NCB1 and NCB2. Similarly, lower zinc concentrations were observed in VPB2 in comparison with NCB1 and NCB2. There was significantly lower (P < 0.05) zinc concentration in affected buffaloes (VPB1 and VPB2) from the ninth month of gestation to term when compared with those in the eighth to ninth mo of gestation, and with those not yet in the eighth month of gestation. Serum selenium concentration were significantly higher (P < 0.05) in control group buffaloes (NCB1 and NCB2) in comparison with vaginal prolapse-affected buffaloes (VPB1 and VPB2). During different stages of gestation, mean serum selenium concentrations varied nonsignificantly (P > 0.05) within each group of buffalo. Based on information obtained from this study, it was concluded that the low serum concentration of copper and selenium are linked to increased incidence of vaginal prolapse in buffaloes during the last trimester of gestation.

[Prolapse of the uterus and cataract: a comparison of veterinary and human medicine in Greco-Roman antiquity]. / Gebärmuttervorfall und Katarakt: Antike Human- und Veterinärmedizin im Vergleich.

A number of surgical interventions in ancient veterinary medicine were modelled on the same procedures in human medicine. This is discussed in some detail for the prolapse of the uterus and the couching of the cataract in horses. In the introductory section, the importance of Switzerland and neighbouring areas for the transmission of ancient veterinary medicine is highlighted.

Enhancing reproductive performance in dairy buffalo: major constraints and achievements.

Buffalo are of high economic importance for farmers in several developing countries but reproductive performance is poor. A large proportion of heifers attain puberty at 3-5 years of age. A good quality diet supplemented with extra nutrients reduces the age of puberty, whereas the effects of administration of exogenous GnRH or equine chorionic gonadotrophin (eCG) are equivocal. The incidence of anoestrus in buffalo ranges from 20 to 80% depending on season. Most buffalo cease ovarian cyclicity during hot summers probably due to the combined effects of nutrition, environment and management. Keeping buffalo cool by wallowing, water sprinklers or shade improves fertility. Supplementary feeding with Urea Molasses Multi-nutrient Blocks (UMMB) for 60 days before calving enhances the early onset of postpartum oestrus. Regular UMMB supplementation also improves pregnancy rates in anoestrous non-pregnant buffalo. Prepartum vaginal prolapse is hereditary and eradication can be achieved by genetic selective breeding programmes. Treatment with calcium, phosphorus and progesterone gives only transient relief to clinical cases. Uterine torsion is the most common cause of dystocia (70%). Deployment of Sharma's detorsion method and anti-stress measures increase survival rates in cases presented within 36 h. In conclusion, greater understanding about the effects of better year-round nutrition, improved management and markers for logical breeding programmes are essential to curtail the incidence of the reproductive disorders that reduce buffalo fertility.

Uterine prolapse in 2 dromedary camels.

Two cases of uterine prolapse in dromedary camels in a herd with concomitant cases of white muscle disease are described. Serum selenium and glutathione peroxidase in whole blood were investigated in both patients and showed statistical difference compared with a control group. Results suggest that selenium deficiency could promote uterine prolapse in dromedary camels.

Níveis séricos de cálcio, fósforo e magnésio em vacas com prolapso cérvico-vaginal ou uterino / Calcium, phosphate and magnesium serum levels in cows with cervical-vaginal or uterine prolapse

Estudaram-se os níveis séricos de cálcio, fósforo e magnésio de 54 vacas, provenientes de diversos municípios do Estado de Säo Paulo. O grupo 1 foi constituído por 27 vacas, sendo seis com prolapso uterino e 21 com prolapso cérvico-vaginal, e o grupo 2 (testemunha) com igual número de vacas clinicamente sadias. O grupo 1 apresentou níveis séricos de cálcio menores do que o testemunha (P<0,01), sendo os níveis mais baixos verificados em vacas com prolapso uterino. Näo se observou diferença nos níveis séricos de fósforo entre os dois grupos. Vacas com prolapso apresentaram teor sérico médio de magnésio inferior às do grupo testemunha (P<0,01). Os resultados parecem indicar que a hipocalcemia pode ser um fator etiológico envolvido no desencadeamento de prolapsos em vacas durante o puerpério
