“…Results of the California mastitis test revealed that out of 95 quarter milk samples, the number of samples showing true positive, true negative, false positive and false negative were 44 (86.27%), 32 (72.73%), 7 (13.73%), 12 (27.27%) respectively. These results correspond with the findings of Sharma et al (2010) and Badiuzzaman et al (2015). In our research, the California mastitis test has high percentage sensitivity and specificity (Table 1).…”

Control of udder health is an essential element in the process of safe milk production. Thus through the mastitis control program dairy farms regularly conduct measures of detection and prevention of udder diseases. Subclinical mastitis is an important disease of dairy cows causing economic losses and physical and chemical changes in milk. The aim of this research was to evaluate the usefulness of the California and the Draminski mastitis test to detect the subclinical mastitis in dairy cows. The efficacy of indirect mastitis tests for diagnosis of the subclinical mastitis was determined by comparing results of mastitis tests with bacteriological findings. The experiment was conducted on two dairy farms (farm A and farm B) Holstein -Friesian breed. A total of 245 quarter milk samples were examined, 95 quarter milk samples with the California mastitis test from farm A and 150 quarter milk samples with the Draminski mastitis test from farm B. A quarter milk samples for bacteriological analysis were taken aseptically during the morning milking in sterile test tubes. On farm A, bacteria growth has not been detected in 46.32% (44/95) quarter milk samples, while on farm B negative bacteriological findings have been found in 50.67% samples (76/150). In present study, sensitivity of the California mastitis test (78.57%) is higher than sensitivity of the Draminski mastitis test (74.32%). The specificity of the California mastitis test and the Draminski mastitis test is 82.05% and 30.26%, respectively. Efficacy of the California mastitis test in detection of the subclinical mastitis in dairy cows is better than that of the Draminski mastitis test, since accuracy of the California mastitis test has been higher.

“…Considering physical and chemical changes of milk and isolation of associated organisms, several methods have been developed to identify subclinical mastitis (Badiuzzaman et al, 2015). Among the tests, California Mastitis Test (CMT), White Side Test (WST) and Surf Field Mastitis Test (SFMT) are arguably the reliable screening tests for sub clinical mastitis (Greiner et al, 2000).…”

Prevalence and identification of subclinical mastitis in cows at BLRI Regional Station, Sirajganj, Bangladesh

Objective:The study was conducted to assess the prevalence of subclinical mastitis in dairy cows at Baghabari milk shed area of Sirajganj and Pabna districts in Bangladesh. Materials and methods: A total of 300 milk samples were collected from crossbred dairy cows, and the milk samples were subjected for using California Mastitis Test (CMT). Besides, data related to farm management were taken from 60 farmers through direct interviews. The CMT was compared with White Slide Test (WST) and Surf Field Mastitis Test (SFMT). The samples showing strong positive reaction to mastitis by CMT were used for the isolation of associated bacteria using conventional bacteriological examinations and biochemical properties. The isolated bacteria were subjected for antibiogram studies by disc diffusion method. Results: Out of 300 samples, 153 (51%) revealed positive reactions denoting that the cows were suffering from subclinical mastitis. Of the 153 samples, 39(13%) were trace-positive, 56(18.56%) were weak-positive, 33(11%) were distinct-positive, and the rest 25(8.3%) samples were strongly positive. In comparison economically among CMT, WST and SFMT, SFMT was found to be the cheapest and easiest. In this study, the cows were mostly infected with mixed infection with Staphylococcus spp., Streptococcus spp., Escherichia coli, Salmonella spp., and some cows had single bacterial infection. It was observed that most of the microorganisms were sensitive to Gentamycin, Amoxicillin and Ceftriaxone, and were resistant to Penicillin, Ciprofloxacin and Colistin sulphate. Conclusion: Overall prevalence of subclinical mastitis in the crossbred dairy cows at Sirajganj and Pabna district is 51%. It indicates that subclinical mastitis is a major threat for dairy industry in the studied areas. Early detection and appropriate preventive measures are suggestive to successful control of the disease.

A cross sectional study was conducted to characterize the present situation of milk production, to identify the existing socioeconomic status of dairy farmers, and to determine the prevalence of subclinical mastitis (SCM) in dairy cows. A total of 229 smallholder dairy farms at Bangladesh Agricultural University surrounding areas were investigated during January to March 2015. Direct interview with farmers, and physical examination of the cows were done to collect farm and cow level data. It appeared that all of the farmers were involved in other occupations besides dairying, in which almost half of them (48.29%) belong to agricultural cultivation. Educational level of the most of the farmers was illiterate to primary level (68.5%). The average annual income of farm owners was Tk. 219109.17, of which around half of the total income comes from livestock. Average milk production of the farms was 7.73 L/day with a range of 0.5 to 305 L. Milk samples were collected from 101 milking cows and were subjected to somatic cell count (SCC) by automatic nucleocounter machine. The overall prevalence of subclinical mastitis was 20.79%. The prevalence of subclinical mastitis was comparatively higher in Sahiwal cows (42.86%), cows that yield >5 to 10 L milk per day, and in late lactation stage (>180 days).
