Evaluation of somatic cell count thresholds to detect subclinical mastitis in Gyr cows.
The objectives of this study were (1) to determine the sensitivity (Se) and specificity (Sp) of somatic cell count (SCC) thresholds to identify subclinical mastitis in Gyr cows caused by major and minor pathogens; (2) to study the effects of month of sampling, rear or front mammary quarters, herd, intramammary infection (IMI), and bacterial species on SCC at quarter level; and (3) to describe t...
متن کاملFractionized 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) ...

متن کاملComparative Effect of Different Milking Methods and Udder Hygiene on Somatic Cell Count and Milk Quality in Dairy Cows
108 milk samples were collected to study the relationship of somatic cell counts (SCC) and milk composition with milking methods and udder hygiene from 27 Holstein Frisian (HF) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at Khyber Pakhtunkhwa Agricultural University Peshawar dairy farm. All animals were randomly distributed into three categories on the basis of ...
متن کاملGenetic associations between somatic cell score and pathogen-specific subclinical mastitis in Norwegian Red cows.
The aim of this study was to estimate heritabilities of and genetic correlations between pathogen-specific subclinical mastitis (SCM) traits and lactation mean somatic cell score (LSCS) in Norwegian Red cattle. Based on data from 130 733 first-lactation cows four binary pathogen-specific SCM traits, Staphylococcus aureus, Streptococcus dysgalactiae, Streptococcus uberis and coagulase-negative s...
