Subclinical mastitis is associated with certain risk factors such as age, lactation stage, milk production and parity. A cross sectional study including 135 cross bred Holstein Friesian dairy cows was undertaken from June 2017 to January 2019 in surrounding villages of district Ganderbal in order to identify major risk factors. The overall prevalence of SCM was 81.48%. The highest prevalence of subclinical mastitis associated with various risk factors was 48.1% (early lactation), 44.54% (5-7 years), 49.09% (>10 litres per day) and 30.90% (3rd parity) respectively. In intensive system of rearing, prevalence was 66.36% whereas in extensive 33.63% was found. In present study, single quarter was affected in 61.81% of SCM infections. In milking method, knuckling and stripping showed more incidence of SCM. In present study, moderate form of mastitis was more predominant (40.9%).

Lactating Dairy Cows

A cross sectional study was conducted between November 2015 and February 2016 in Hawassa town, SNNPR, Ethiopia to determine the overall mastitis prevalence and identify the role of some selected risk factors in 183 randomly selected small holder lactating dairy cows of 53 high grade Holstein Friesian, 113 Holstein indigenous zebu cross and 17 indigenous zebu breeds. The prevalence of clinical mastitis was determined through examination of abnormalities of milk, udder or cow. The prevalence of subclinical mastitis determined by using indicator paper test. From total 183 lactating dairy cows examined for bovine mastitis 9(4.9%) had clinical mastitis, while 56(30.6%) subclinical mastitis. Out of 9(4.9%) clinical mastitis, 9.43 and 3.53% occurred in high grade Holstein and Holstein indigenous zebu, respectively, but indigenous zebu breed was found not affected. Subclinical mastitis at cow level based on indicator paper test was significantly high (32.07%) in Holstein, (30.9%) in cross breed and (23.5%) in indigenous zebu (p<0.05). Quarter level subclinical mastitis prevalence based on indicator paper test was 32.07, 30.2% and 23.5% in Holstein, cross breed and indigenous zebu, respectively. From the potential risk factors considered, breed (X2=17.3, p<0.05), presence of teat lesion and tick infestation (X2=7.73, p<0.05), stage of lactation (X2=13.8, p<0.05), and parity number (X2=19.4, p<0.05) had significant effect on the prevalence of subclinical mastitis. Considering the possible significant economic losses that could be incurred by both clinical and subclinical mastitis, attention should be paid for further detailed investigation and control measures.

Background and Aim: Subclinical mastitis (SCM) is a disease that frequently attacks lactating dairy cows and possibly decreases production, causing economic losses to farmers. This study aimed to define the prevalence of SCM and risk factor-associated related management practice by dairy farmers in East Java, Indonesia. Materials and Methods: The milk sample per quarter of individual lactating Friesian–Holstein cows (592 samples) was collected from 148 cows from 62 selected farms in the region with high dairy cattle populations in Malang, Sidoarjo, Mojokerto, Probolinggo, Pasuruan, Lumajang, Jember, and Banyuwangi. SCM determination was performed using the California mastitis test. A survey including field observation and interviews with farmers was conducted to find out the management practices of the selected farms. The analysis of risk factors was conducted by multinomial regression using the IBM SPSS version 26.0 (IBM SPSS Statistics, Chicago, USA). Results: In addition, 68.18% and 66.72% at the cow and quarter levels, respectively, of the lactating dairy cows examined had SCM. In multinomial regression, four variables were significantly given impact in association with the SCM prevalence in identifying related lactation stage (odds ratio [OR]: 1-2 months=5.67, 2-6 months=9.435), teat wiping after milking (OR=42.197), house cleanliness (OR: dirty=0.120, moderate=0.527), and location (regencies) of raising the cows (OR: Sidoarjo=0.076, Mojokerto=0.165, Jember=1.210, Probolinggo=3.449, Lumajang=1.638, Malang=1.210, and Pasuruan=0.681). Conclusion: The SCM prevalence in East Java is relatively high and a threat to the dairy industry's performance. This study found a significant association with SCM that needs to be considered in the practice of management to prevent and control SCM. However, the finding also suggested that hygienic management practices performed by farmers need to be improved to reduce SCM incidents.
