“…However, there is some controversy among investigators about risk factors and consequences of metritis (Kaneene and Miller, 1995;Rajala and Gröhn, 1998;Bruun et al, 2002;Goshen and Shpigel, 2006;Wittrock et al, 2011) because research goals, study methodology, and quantification criteria differ greatly from study to study. These need to be considered in the estimation of economic losses associated with metritis.…”

The objectives of this study were (1) to describe the risk factors, incidence, and productive and reproductive consequences of metritis in dairy cows, and (2) to estimate the financial losses associated with metritis using data gathered from 4 Holstein dairy farms in Isfahan, Iran. Calving records from March 2008 to December 2013, comprising 43,488 calvings, were included in the data set. The effects of metritis on productive and reproductive performance were analyzed using a mixed linear model for primiparous and multiparous cows separately and in an overall data set (all cows combined), whereas risk factors on metritis incidence were examined using a multivariable logistical regression model for the overall data set. The incidence of metritis per cow per year was 13.2% on average and ranged from 9.0 to 15.8%. Results of logistic regression analysis demonstrated that calving year, parity number, calving season, twinning, dystocia, and retained placenta were significantly associated with the occurrence of metritis, whereas previous metritis incidence did not show an association. Greatest odds of metritis occurred in first-parity cows that calved in winter and had retained placenta, twinning, and dystocia in recent years. A case of metritis significantly reduced the 305-d milk yield in primiparous and multiparous cows and overall, but had no significant effects on 305-d fat and protein percentages in either primiparous or multiparous cows. Overall, a case of metritis reduced 305-d milk yield by 129.8±41.5kg/cow per lactation. The negative reproductive effects due to metritis were smaller and nonsignificant for primiparous cows compared with multiparous cows. Overall, a case of metritis increased days open and number of insemination per conception by 16.4±1.2 and 0.1±0.0 per cow per lactation, respectively. Among the individual farms, metritis costs ranged from $146.4 to $175.7 with a mean of $162.3/case. The model to calculate metritis costs proposed here could be used to estimate economic losses for metritis in other developing countries, where farm productive and economic data are generally scarce.

“…Metritis result in decreased dry matter intake, and hence, multiparous cows with metritis in early lactation produce less milk than the healthy cows. This difference is greatest during the first 20 weeks of lactation (Wittrock et al, 2011).…”

A longitudinal study was conducted on post-partum reproductive problems in small and medium scale dairy production systems in Wolaita Sodo from October 2011 to May 2012. The objectives of the study were to identify the major clinically manifested postpartum problems, estimating the prevalence and investigating the potential risk factors related to the occurrence of postpartum problems of dairy cows in the area. From a total 634 dairy cow examined, 57(8.99%) cows had different types of partum and postpartum problems: abortion (0.63%), dystocia (0.79%), retained fetal membrane (3.36%), uterine prolapse (0.47%), milk-fever (1.42%) and metritis (2.84%). A significant difference was observed in the occurrence of postpartum problems among age groups of cows (P <0.05) and parity (P <0.05). Higher prevalence of postpartum problems was recorded in older (15.20%, CI=7.82-22.61) than the younger cows. The prevalence of postpartum problems was higher in cows with seven and more than seven parity (15.70%, CI=7.11-24.31) than those cows having less than seven parity. Dairy cows postpartum problems were found to be one of the major problems in Wolaita Sodo. To reduce the postpartum problems due attention should be given for proper herd or individual cow management, early identification and diagnosis of the reproductive problems and awareness creation for owners.

The objective of the study was to determine the effect of puerperal metritis prevalence in high yielding Holstein cows on productive (305 days, actual milk yields), reproductive (days to first estrus, days open and services per conception) variables and culling rates. Throughout the study, 2885 dairy records were collected from high yielding private Holstein dairy farm (average milk yield was up to 9000 kg) for 3 successive lactation seasons. Dairy cows were classified according to their uterine affection into two groups, healthy and those with puerperal metritis. Dairy cows which affected with puerperal metritis were diagnosed during the first 3 weeks of lactation. Metritic cows were diagnosed and treated at the discretion of the herd veterinarian. Affected dairy cows were grouped into four groups according to time of the puerperal metritis attack during the first 21 Days In Milk (DIM) as (<5; 5-10; 10-15 and >15 DIM, respectively). Moreover, the dairy females were grouped into 3 groups according to frequency of puerperal metritis of once, twice and triple, respectively. Dairy cows were also grouped according to their calving season (winter, spring, summer and fall calving seasons). Productive, reproductive variables and culling due to puerperal metritis were detected from the on-farm record system (DairyComp305). Results of this study revealed that, puerperal metritis had bad effects on high yielding cows productive and reproductive variables, that decreased the 305 milk yield, increased days to first estrus, days open and number of services per conception. Moreover, the occurrence of puerperal metritis increased during the warm months of spring and summer seasons. Also, the occurrence of such disease was increased during the first 10 days of postpartum as (89.98%) of the affected cases occurred within this period. Care must be directed to dairy cows which had a history of puerperal metritis as these cases had a greater tendency for recurrence. Also, the re-attacked cows with puerperal metritis had a great chance to be culled from the dairy herds, as they reached to (53.33% and 100%) for the second and third attack, respectively.
