Economic Impact Of Bovine Mastitis In Espírito Santo, BRAZIL

The objective was to calculate the economic losses of clinical and subclinical mastitis in dairy cows. Eighteen farms and 175 lactating cows were evaluated from February to December 2015. A black black-ground mug test was performed to assess the presence of clinical mastitis and milk was collected from the tank to verify economic losses through somatic cell count (TSCC) for each property. The economic losses generated by clinical mastitis were calculated considering the cost of treatment and the grace period with milk disposal. The calculation of the loss of production of the property was stipulated through the reduction of production caused by the high TSCC. The economic impact of clinical mastitis was an average of US $ 53.67 for each positive case, with the disposal of milk being the main factor to increase economic losses. Estimates of losses about TSCC were US $ 2.58 per day and the US $ 77.40 monthly, due to reduced milk production about the high somatic cell count found in the tank. It is necessary to inform producers about the high costs caused by losses of clinical mastitis and the high somatic cell count in milk.
