Dairy goat production is an emerging enterprise, which has a lot of potential for poverty alleviation, improved nutrition, and increased income for the poor and can play a role in contribution towards Kenya’s development plan. Inadequate information on prevalence of subclinical mastitis and antibiotic sensitivity are some of the challenges facing this industry. This study was carried out in dai...

A new breeding value estimation procedure for mastitis traits has been implemented in the Dutch/Flemish dairy genetic evaluation. This breeding value estimation uses incidences of subclinical mastitis together with five indicator traits derived from test day somatic cell counts to predict the breeding value for resistance against subclinical and clinical mastitis (SCM and CM, resp.). The mastit...

*Corresponding Address: [email protected] The study was conducted to estimate the prevalence of subclinical mastitis (SCM) in dairy cows in the Bhaktapur District of Nepal. A total of 200 milk samples were collected from 50 dairy cows. The California mastitis test (CMT) was carried out on quarter milk samples to determine the prevalence of subclinical mastitis. California Mastitis Test (CMT)...

Subclinical mastitis is a widely spread disease of lactating cows. Its major pathogen is Staphylococcus aureus (S. aureus). In this study, we performed genome-wide integrative analysis of DNA methylation and transcriptional expression to identify candidate genes and pathways relevant to bovine S. aureus subclinical mastitis. The genome-scale DNA methylation profiles of peripheral blood lymphocy...

BACKGROUND Studies outside the Nordic countries have indicated that subclinical mastitis (measured by milk somatic cell count or the California Mastitis Test), intramammary infections (IMI), or blind quarters in beef cows may have negative effects on beef calf growth. Knowledge on prevalence of such udder health problems in Swedish beef cows is scarce. Therefore, the main aim of this study was ...

The aim of this work was to identify and to characterise Staphylococcus aureus isolates associated with subclinical mastitis obtained from milk of lactating cows showing a California Mastitis Test (CMT) score result of traces, 1, 2 or 3. Coagulase, hemolysis, presence of capsule, slime formation, biofilm production, autoaggregation, hemagglutination and antibiotic susceptibility were assessed t...

the objective of the present study was to compare the efficacy of conventional and extendedintramammary (imm) therapy of persistent subclinical mastitis in lactating dairy cattle using nafcillinpenicillin-dihydrostreptomycin combination (npd). sixty-five dairy cows with 126 infected quarters were enrolled in the study. infected cows were allocated randomly to 1 of 3 different treatment regimens...

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...

The transition period is the most critical time of the cow’s lactation cycle that is associated with the onset of mastitis. In this study, changes of plasma proteins in cows (n = 12) with or without subclinical mastitis after calving were determined by two-dimensional electrophoresis (2-DE), which detected 18 spots with variations in protein spots abundance. These spots were identified by liqui...

The aim of the present study was to assess the haemolytic and proteolytic activity of coagulase-negative staphylococci (CNS) isolated from cows with mastitis. The study was conducted on 100 CNS strains: S. xylosus (n=28), S. chromogenes (n=26), S. haemolyticus (n=25), S. sciuri (n=14), S. warneri (n=4), S. hominis (n=2), S. saprophyticus (n=1); 22 CNS were isolated from cows with clinical masti...
