Accuracy rate of mastitis on-farm test (udder check) in comparison to somatic cell count (S.C.C) in dairy herd

Mastitis in bovine is an important disease in milk herds that cause economical losses due to decrease of milk production and treatment costs. Somatic cell count (SCC) is one of traditional test in mastitis diagnosis. The aim of current study was to evaluate the accuracy of udder check (on-farm) in comparison to SCC in industrial livestock. Current study was conducted in a 100 bovine livestock, samples were evaluated by udder check test at farm and simultaneously for SCC measurement were sent to, Pegah pasteurized Milk Company. Then the accuracy of two tests was evaluated and compared. The result was evaluated by descriptive method in SPSS ver. 22. The results of study indicated that SCC was 2014.86×10 6 in studied bovine. In addition, SCC results demonstrate 48 percent positive and remnant was negative. Udder check test results indicate 76 percent of samples was positive which 22% was 3positive, 21% was 2positive, and 33% was 1positive and positive cases was significantly different from SCC test (p<0.05). The results indicated that the udder check has a higher specificity and sensitivity in mastitis detection and successfully could detect the subclinical mastitis at farm and provide opportunity to early treatment.
