Mastitis in dairy cows causes loss of income due to reduced productivity, low quality milk, and chronic infection to the point that dairy cows have to be culled. In order to prevent antibiotic contamination of milk, several antibiotics have been used to treat mastitis on farms, and farmers are prohibited from transporting milk from treated or withdrawal-period cows to milk collection facilities. A concern with antibiotic use was that some farmers did not follow the recommended antibiotic dosages to reduce the cost of treating mastitis. Due to this issue, the farm has continued to experience mastitis and developed long-term antibiotic resistance. The somatic cell count in cow's milk during mastitis treatment with and without antibiotics was evaluated in this study. A total of 44 samples of cow's milk consisted of 24 samples of cow's milk that had not received antibiotics and 20 of cows that had received antibiotics for the treatment of mastitis. The results demonstrated that the milk from the cows without receiving antibiotics had a high somatic cell count, with a mean of 2775 × 103 cell/mL. The milk of cows during mastitis treatment contained with a mean of 1856 ×103 cell/mL somatic cells count. This study demonstrated that the somatic cell count might be used to show intramammary inflammation. Results of intramammary and intramuscular antibiotics were shown highly beneficial in reducing udder inflammation and the quantity of somatic cells. The somatic cells count was a relatively inexpensive way for dairy farmers to assess udder health. Dairy farmers might monitor the quantity of milk somatic cells to assess the effectiveness of antibiotics in treating mastitis.
