BACKGROUND Subclinical mastitis is of concern in veterinary hospitals because contagious mastitis pathogens might be unknowingly transmitted to susceptible cows and then back to their farm of origin. OBJECTIVES To evaluate the California mastitis test (CMT) as an indicator of intramammary infection (IMI) in lactating dairy cows admitted to a veterinary hospital. ANIMALS A total of 139 admis...

The study was conducted from November 2015 to April 2016 to estimate the prevalence of clinical and subclinical mastitis in lactating cows, to assess the associated risk factors, and to isolate the major bacterial pathogens in dairy farms in selected district of Eastern Harrarghe Zone, Eastern Ethiopia. The study was carried out in 384 dairy cows based on data collection, farm visit, animal exa...

A cross-sectional study was carried out from November 2008 April 2009 to estimate the prevalence of mastitis caused by Staphylococcus aureus, to assess the associated risk factors and to determine the antimicrobial resistance pattern in Adama town, East Shoa, Ethiopia. From 102 markets oriented small holder dairy farms, a total of 300 lactating cows were tested for mastitis using the California...

A 4-year retrospective study was performed to determine the clinical, bacteriological and epidemiological aspects of acute clinical mastitis in seven Israeli dairy herds. A total of 1124 clinical mastitis cases were detected by abnormal changes in the milk and udder with concurrent decrease of at least 25% in daily milk production. A total of 1190 quarters were affected with clinical mastitis i...

Farmers frequently have to decide whether to keep or to replace cows that suffer from clinical mastitis. A dynamic programming model was developed to optimize these decisions for individual cows within the herd, using the hierarchic Markov process technique. This technique provides a method to model a wide variety of cows, differing in age, productive performance, reproductive status, and clini...

The aim of this study was to determine withdrawal periods (WP) and tissue irritation after administration of three intramammary antibiotics [Curaclox LC (Norbrook (ARK AH)], Spectrazol Milking Cow (Schering-Plough AH) and Rilexine 200 LC [Logos Agvet (Virbac)] in goats with clinical mastitis. Withdrawal periods in goats with clinical mastitis treated with Curaclox LC, were not significantly dif...

Materials and Methods Mastitis is the inflammation of mammary gland; it is a complex disease which continues to have a major economic impact on the dairy industry throughout the world [1, 2]. The losses due to mastitis in USAalone are 1.7 billion dollars [3] while in India the losses are estimated to be about Rs. 7,165 crores [4]. The term mastitis comprises two relatively independent health pr...

Mastitis continues to be a cause of significant economic loss to the dairy industry internationally. Despite significant advances in our understanding of the disease, clinical and sub-clinical mastitis remains a problem in dairy herds and prevalence rates in many countries remain similar to those published decades ago. In the complex milieu of the modern dairy farm, it is the interaction of pro...

A prospective cohort study was undertaken in two commercial California dairies. The treatment group, 246 cows, received three doses of a whole cell bacterin of J5 Escherichia coli (mutant of E. coli O111:B4) plus Freund's incomplete adjuvant vaccine (two in the dry period and one after calving) while 240 unvaccinated cows served as controls. Thirty-five cases of clinical coliform mastitis were ...

This study aims to determine the correlation between dairy cattle teat length at several lactation periods and subclinical mastitis profile. used 43 periods. The of cows studied were 1, 2, 3. Subclinical testing IPB-1 Mastitis Test, was measured using a measuring tape (cm). data is taken then analyzed average described. results showed that 5.11 cm did not experience mastitis, while 5.48 cm, 6.0...
