Prevalence and Risk Factors for Retention of Fetal Membranes in HF Dairy Cows

A retrospective study was carried out to analyze the risk factors associated with the prevalence of RFM. The results of the present study revealed that a total of 1260 calvings had occurred between January, 2006 and December, 2013. Out of these 1260 calvings, 112 calvings had followed by the cows retaining their fetal membranes Thus, the overall prevalence of RFM in HF cows was determined as 8.80 per cent. One hundred and twelve cows in which the calvings were followed by RFM were categorized to be between 2-4, 4-6, 6-8, and over 8 years of age it was observed that the prevalence of RFM progressively and significantly increased with the advancing age. The prevalence of RFM in cows aged 2-4, 4-6, 6-8, and over 8 years were recorded as 13.39, 19.64, 25.89 and 41.07 respectively. Reccurance of the same condition was also recorded in 9 (8.03 %) cows subsequent to next calving. Further, 2 of these cows again had RFM even after their next calving. Subsequent history was not available as these cows were culled.
