Metritis and endometritis in high yielding dairy cows Metritis en endometritis bij hoogproductief melkvee
Since a few decades, dairy cows have shown a steep increase in milk production, which is unfortunately accompanied by a dramatic decline in reproductive performance. In these high yielding cows there are more puerperal problems than in low yielding cows, such as retained placenta, acute metritis and abnormal vaginal discharge. Cows affected by retained placenta and/or acute metritis are further...
متن کاملCytological endometritis in dairy cows: diagnostic threshold, risk factors, and impact on reproductive performance
We determined the threshold proportion of polymorphonuclear leukocytes (PMNs) for a diagnosis of cytological endometritis (CEM), the risk factors for this condition, and its impact on reproductive performance in dairy cows. Uterine cytology was performed on 407 Holstein cows 4 weeks postpartum to determine the proportions of endometrial cells and PMNs. A receiver operator characteristics curve ...

In these modern high yielding cows authors worldwide mention a higher number of puerperal problems, such as retained placenta, acute metritis and abnormal vaginal discharge. All of which are known to negatively influence reproductive capacity of thes...
متن کاملImproving Dairy Cattle Reproductive Performance
• A calving interval of 13.5 months is an achievable goal that will produce higher daily milk yield and higher milk yield over the length of the lactation. To achieve this goal average days to first service should be <80, yearly 21-day Pregnancy Rates should average >20% and culling for reproductive failure should not exceed 10%. • Management must set standard operating procedures for all aspec...
متن کاملReproductive Performance Definition in Dairy Cattle: Affective Factors
The reproductive performance of a dairy herd has a significant effect on the profitability of that herd. Common measures of reproductive performance are days to first service, days to conception, calving interval, services per conception, conception rate, estrus detection rate, and pregnancy rate. Most cow operations would benefit economically by reducing the number of operational days, decreas...
