Clinical, hematobiochemical, and ultrasound profiles of mastitis in dairy cows

This study examined clinical, hematobiochemical, and ultrasound findings in cows with mastitis cases. A total of 164 cows were included, comprising 31 healthy animals and 133 cows with udder and milk changes. Significant differences between mastitis-affected and healthy cows were observed in udder and teat measurements. Mastitis-affected cows and control cows did not differ significantly in total leukocytes, lymphocytes, eosinophils, and basophils. However, mastitis-affected cows had lower monocyte counts and higher neutrophil counts. Ultrasonography showed increased milk vein measurements and distinct parenchymal changes in mastitis-affected quarters. Udder abscesses were present in 21% of mastitis-affected cows.
