The present study was designed to determine the quarter-wise comparative prevalence of mastitis in buffaloes and crossbred cows. Milk samples collected from 50 dairy buffaloes and 50 crossbred cows were tested for subclinical mastitis by Surf Field Mastitis Test. In addition, all milk samples were processed for isolation and identification of pathogens. In buffaloes, overall prevalence of subcl...

the objective of this study was to estimates the genetic and environmental components for the lactation curve parameters, milk yield, age at first calving (afc), calving interval (ci) and somatic cell count (scc) in iranian holstein cows. the dataset consisted of 210625 test day records from 25883 cows with milk yield in the first parity recorded from july 2002 to september 2007 in a total of 9...

The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. I...

four-hundred milk samples from half udders of 20 flocks of native breed goats were asepticallycollected. the samples were examined by california mastitis test (cmt). twenty-one (5.25%) of 400 werecmt-positive. the cmt-positive samples were then cultured and the following bacteria were isolated:staphylococcus aureus in 3 (14.28%), cns (coagulase-negative staphylococci) in 14 (66.66%), streptococ...

Bovine mastitis, which is an inflammation of the mammary gland frequently resulting from bacterial infection, causes the majority of economic losses to the dairy producers. The prevalence of mastitis in dairy cattle is relatively high. Bovine mastitis can be classified based on clinical futures as clinical or subclinical. Both forms produce significant economic losses due to rejected milk, degr...

Mastitis is by far the most common and most costly disease in milk production in industrialised countries. Costs are related to loss in milk quality, decreased milk production related to subclinical mastitis, discarded milk, replacement cows, cost of treatment and labour costs [1]. This disease is the most frequent reason for the use of antimicrobials in dairy cows [2]. It can be classified int...

This study was carried out to determine the prevalence of coagulase-negative staphylococci in clinical and subclinical mastitis in commercial and small-scale farms in Zimbabwe. Thirty five quarter milk samples from clinical mastitis cases and 371 quarter milk samples from cows with subclinical mastitis were cultured for bacterial pathogens. The most frequent pathogens isolated in clinical masti...

Buffaloes are the second largest source of milk. Mastitis is a major impediment for milk production, but not much information is available about bubaline mastitis, especially subclinical mastitis. The aim of this study was to (a) investigate the application of various tests for the diagnosis of bubaline subclinical mastitis, (b) identify the major bacteria associated with it, and (c) evaluate t...

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...

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...
