Prevalence and Risk Factors of Mastitis in Lactating Dairy Cows at Baghabari Milk Shed Area of Sirajganj

Abstract

A cross-sectional study was carried out on a total of 330 lactating dairy cows at Baghabari, Sirajganj to determine the prevalence and risk factors of clinical (CM) and sub-clinical (SCM) mastitis using California Mastitis Test (CMT), White Side Test (WST) and Surf Field Mastitis Test (SFMT) during the period from July to December, 2009. Of all cows tested, 2.12% (n=7) cows were affected with CM and 37.58% (n=124), 36.67% (n=121) and 35.15% (n=116) cows showed positive reaction for SCM by CMT, WST and SFMT respectively. The overall prevalence of SCM was 36.46% and CMT showed better performance in detecting SCM (37.58%) among three indirect tests used. The prevalence of SCM was significantly (p<0.01) higher (47.61%) in age group more than 13 years than others. A significantly (p<0.01) higher prevalence of SCM was observed in parity number more than 11 than others. The prevalence of SCM was significantly (p<0.01) higher (37.12%) in cows yielding >10L of milk than others. The prevalence of SCM was highest in late lactation (72.45%) followed by early (40%) and mid lactation (27.56%). Herds having 16 or more milch cows had significantly (p<0.05) higher SCM than those with fewer milch cows.DOI = http://dx.doi.org/10.3329/bjvm.v8i2.11200 Bangl. J. Vet. Med. (2010). 8 (2) : 157-162

Subclinical mastitis in dairy cows: somatic cell counts and associated bacteria in Mymensingh, Bangladesh

“…Another study conducted by Katsande et al, (2013) showed comparatively lower prevalence (16.3%) of SCM in Zimbabwe. Previous studies in different regions of Bangladesh reported that the prevalence of SCM based on California Mastitis Test (CMT) varies from 29% to 37.6% (Islam et al, 2011;Islam et al, 2010) and based on SCC was 55% (Hoque et al, 2015). However, comparative higher prevalence of SCM indicates lack of awareness about SCM and farmers are not adapted to use different screening tools to detect SCM in timely fashion and maintain the udder and teat hygiene.…”

Prevalence of Subclinical Mastitis in Lactating Cows and Efficacy of Intramammary Infusion Therapy

“…Subclinical mastitis is 15 to 40 times more prevalent than the clinical form, is of long duration and difficult to detect ( (Almaw et al, 2008;George et al, 2008;Sarker et al, 2013). In Bangladesh, the prevalence of SCM is recorded from 20 to 44% at cow level based on California Mastitis Test (CMT) (Rahman et al, 2009;Islam et al, 2010;Rabbani and Samad, 2010). The efficacy of antibiotic therapy for intramammary infections (IMIs) early in lactation is scarce and few, with the ones carried out reporting mixed results.…”

Occurrence of bovine mastitis and isolation of <i>Staphyloccocus</i> species from fresh cow milk in settled Fulani herds in Kaduna State, Nigeria

“…The study recommends standards hygienic measures during milking and culling of infected cows to stop the spread of pathogens to uninfected Key words: mastitis, prevalence, Cow milk, Staphylococcus spp, settled Fulani herds, Kaduna State Dairy production systems provide milk that is rich in carbohydrates, fats, vitamins and minerals for the ., 2004; Mekibib et 2010). However, milk production does not always meet the population's demands due to several factors, common among which is mastitis (Islam et al, 2010;Kurjogi and Kaliwal, 2014). Mastitis is a complex and costly disease of dairy animals resulting from interplay between the dairy animal and the environment including the milking 2008).…”

“…In almost all dairy animals, microorganisms are mainly incriminated in mastitis, but some predisposing factors such as poor management and hygiene, teat injuries and faulty milking machines, pendulous udder ize of teat orifice in high yielding cows, etc. play an important role in the development of mastitis (Islam et al, 2010).…”

“…Mastitis is a complex and costly disease of dairy animals resulting from interplay between the dairy animal and the environment including the milking 2008). Mastitis is inflammation of mammary gland affecting all the species of domestic animals and characterized by the changes in physical appearance of milk, swelling, redness, and rises in temperature of udder (clinical mastitis) and in many case no visible changes in milk or udder (sub clinical mastitis) are apparent (Wilson et 2011;Kurjogi et Bovine mastitis has great economic impact on dairy industry and is associated with multi-etiologic agents, with one third of all dairy cows estimated to be infected with some form of mastitis in one or more quarters (Samad, 2008;Islam et al, 2010). In almost all dairy animals, microorganisms are mainly incriminated in mastitis, but some predisposing factors such as poor management and hygiene, teat injuries and faulty milking machines, pendulous udder with long teats, larger size of teat orifice in high yielding cows, etc.…”
