“…The proportion of animals experiencing RFM across all cows was 14.3%, which is above the accepted range previously suggested for North American and British dairies (Laven and Peters, 1996;Kelton et al, 1998), but in accordance with results from other regions (Han and Kim, 2005). The reduced risk of RFM found in the treated group could support the hypothesis that the diet facilitates uterine involution by preventing subclinical hypocalcaemia.…”

“…On the other hand, Larson et al (1985) reported that seasons were associated with development of RP, with a higher incidence rate during the warm season for the first lactation and during the cold season for the second lactation. Also, Han and Kim (2005) reported calving season was not associated with the incidence of RP. Increased risk of RP in cows with calving difficulty was consistent with numerous previous findings (Han and Kim 2005;Chassagne et al 1996;Correa et al 1993).…”

“…Increased occurrence of RP in cows with dystocia might be due to lack of tone and slow involution or damage to the uterus by mechanical stress resulting from calving difficulty (Klerx and Smolders 1997;Markusfeld 1987). Previous reports (Han and Kim 2005;Chassagne et al 1996) on the relationship between gestation length and the incidence of RP showed that shorter gestation lengths are associated with a higher incidence of RP. Short gestations were also related to an increased risk of developing RP in this study.…”

“…Our finding that cow parity is related to increased risk of RP is consistent with previous studies (Gröhn et al 1990;Bendixen et al 1987) which reported that the incidence of RP increased with advancing parity. On the other hand, Han and Kim (2005) reported no association between RP and parity in dairy cows. Similar to our results, others reported increased odds of RP in cows with abortion, milk fever and stillbirth (Gröhn and Rajala-Schultz 2000;Correa et al 1993;Sandals et al 1979).…”

The objective of this study was to evaluate the association between cow-specific risk factors and the lactational incidence risks of retained placenta (RP), metritis (MET) and clinical mastitis (CM) in 57,301 dairy cows on 20 large dairy herds in Iran between January 2005 and June 2009. A multivariable logistic regression model was used to identify risk factors for MET, RP and CM and quantify their odds ratio (OR). The lactational incidences of MET, RP and CM were 8%, 5.2% and 18.9%, respectively, and significant risk factors for MET were dystocia (OR = 4.32), stillbirth (OR = 6.26), RP (OR = 27.74), twin births (OR = 6.57), primiparity (OR = 1.68), calving during winter season (OR = 2.45) and male calves (OR = 2.41). Significant risk factors for RP were dystocia (OR = 3.17), stillbirth (OR = 3.18), abortion (OR = 8.46), milk fever (OR = 3.66), twin births (OR = 2.76), pluriparity (OR = 2.69), calving during winter season (OR = 1.86) and shorter gestation length of dairy cows (OR = 3.82). Also, significant risk factors for CM were RP (OR = 9.45), milk fever (OR = 12.36), pluriparity (OR = 2.83), calving during winter season (OR = 1.68) and the first months of lactation (P < 0.001)) and SCC concentrations at previous lactation (OR = 1.82). The current study indicates that differentiation can be made among cows in the risk of having MET, RP and CM based on a combination of cow factors. These differences among cows could be useful to aid the better detection of these diseases in the dairy herds.

BackgroundUterine torsion in dairy cows generally occurs during gestation. However, some cows develop uterine torsion after calving, and the details of which are not known.ObjectivesThe present study aimed to investigate the clinical signs, epidemiological characteristics and treatment methods of 23 cases of post‐partum uterine torsion in dairy cows.MethodsA total 23 Holstein dairy cows diagnosed with post‐partum uterine torsion were investigated. The clinical signs and epidemiological information were reviewed from medical records. The diagnostic methods, findings and treatment method of each case were recorded.Results and conclusionsPost‐partum uterine torsion is typically observed in dairy cows 9.6 ± 3.7 days after calving. That is, 21 out of 23 [91%] were multiparous and 8 out of 23 [34.8%] were characterised by multiple births. The retained placenta was observed in at least 20 out of 23 [87%], and a standing abnormality was observed in 18 out of 23 [78.3%]. The clinical signs observed in all cases included anorexia and accumulation of lochia and gas with a putrid odour in the uterus. In addition, eight and nine cases treated with the transrectal manual method and laparotomy, respectively, were cured. In conclusion, post‐partum uterine torsion in dairy cows developed around 10 days after calving, with anorexia and accumulation of lochia and gas with a putrid odour in the uterus. It has been suggested that torsion can be reconstructed using the transrectal manual method or laparotomy.
