The effect of subclinical mastitis on milk composition in dairy cows
Authors
Abstract:
Milk samples were collected from quarters of 35 cows with subclinical mastitis (California mastitis test [CMT] positive and somatic cell counts [SCC] >500,000 cells/ml in individual quarter foremilk), as well as from 37 healthy controls. Compared to the levels observed in milk from healthy quarters, milk from quarters with subclinical mastitis showed elevated sodium (91.97 vs 52.93 mg/dl), chloride (>0.14 vs

Fractionized milk composition in dairy cows with subclinical mastitis
Mastitis is the inflammatory reaction of the udder to invading pathogens. One of the most apparent reactions is the increased influx of immunoreactive cells from blood into milk inducing a dramatic increase of milk somatic cell counts (SCC). We have investigated (i) the relationship between log SCC/ml in infected quarters being >6 (n = 8, group I) or varying between 5.4 and 6 (n = 8, group II) ...

full textEffect of mastitis on milk perchlorate concentrations in dairy cows.
Recent surveys have identified the presence of perchlorate, a natural compound and environmental contaminant, in forages and dairy milk. The ingestion of perchlorate is of concern because of its ability to competitively inhibit iodide uptake by the thyroid and to impair synthesis of thyroid hormones. A recent study established that milk perchlorate concentrations in cattle highly correlate with...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Identification of Streptococcus canis isolated from milk of dairy cows with subclinical mastitis.
Streptococcus canis was isolated from 31 milk samples from 11 cows in a dairy herd (with 49 lactating cows) affected by subclinical mastitis in north Rhine-Westphalia, Germany. Thirty-one isolates from the infected udder quarters were further characterized for their phenotypic and molecular properties. Most isolates (83.9%) produced alpha-galactosidase, and all were negative for beta-d-glucuron...
full textThe prevalence of clinical and subclinical mastitis in dairy cows in the central region of Fars province, south of Iran
licensed dairy farms in the central region of Fars province were randomly selected in order to participate in aseasonal prevalence study. A cross-sectional study was designed to determine prevalence at cow and quarterlevel based on clinical signs for clinical mastitis and indirect tests for subclinical mastitis. 6180 quarters from1545 dairy cows were tested by clinical examination and Californi...
