| Objective: The study aimed to evaluate the data obtained by comparing the bacteriological examination of dairy cattle with subclinical mastitis and the change in somatic cell count, which is used as a quality indicator. Methods: For this purpose, milk samples were taken from a total of 280 randomly selected Holstein breed dairy cattle and from 1120 mammary lobes, which did not show clinical signs of mastitis. The general microbial status of the milk samples was assessed using the California Mastitis Test (CMT) and somatic cell count (SCC), and bacterial species were identified through identification analysis. Results: According to the CMT results, 58 (20.7%) of the dairy cattle were found positive for subclinical mastitis. Of the 232 breast lobes included in the study, they were scored as 82 of them (35,3%) CMT (-), 47 of them (20,3%) CMT (+), 78 of them (33,6%) CMT (++) and 25 of them (10,8%) CMT (+++). The bacterial growth rate in CMT-positive mammary lobes was determined to be 64,66%, and E. coli (26,10%), S. aureus (21,29%), and S. agalactiae (20,08%) were isolated from samples, respectively. When the SHS values in the samples were examined, it was determined that the values varied between 50,000 and 960,000 cells/mL and the average value was 333,862 cells/mL. Conclusion: The results indicate that subclinical mastitis is prevalent in dairy farms, and that Staphylococcus spp. and E. coli are more frequently isolated from the milk obtained from these animals. In the context of food safety, it is considered that the implementation of measures related to udder health and milking hygiene in the milk supply chain will contribute to the production of high-quality milk and dairy products. |
