Characterization of distributions of somatic cell counts [PDF]
Journal of Dairy Science, 2009 There is more useful information in distributions of somatic cell count (SCC) than is currently used in practice. Analysis of SCC of individual quarters (n = 450,834 quarter records of 133,102 cows) showed that the presence of pathogens did not change the peak of the SCC distribution.

The influence of TLR4 gene polymorphisms on milk quality and composition of Lithuanian Holstein cows
Mljekarstvo, 2020 This study investigated bovine TRL4 gene c.9421C>T, c.2021C>T and c.-10C>T polymorphisms and their relationship with somatic cell count and indicators of milk composition. Blood samples were collected from 152 Lithuanian Holstein dairy cows.

A Practical Application of Genomic Predictions for Mastitis Resistance in Italian Holstein Heifers
Animals, 2022 Heifers are a fundamental resource on farms, and their importance is reflected in both farm management and economy. Therefore, the selection of heifers to be reared on a farm should be carefully performed to select only the best animals.

Quality profile of milk from high producing dairy cows vaccinated against mastitis
Ветеринария сегодня, 2021 One of the raw milk quality criteria is the count of somatic cells, produced by the cow’s immune system to fight infectious diseases of the mammary gland.

The effect of teat cup liner type on the teat condition of Holstein primiparous cows [PDF]
Journal of Central European Agriculture, 2018 The objective of this study was to test the effect of two different teat cup liners (difference in: head diameter, length, body shape and with / without of air vent) on the teat condition score after milking (hyperkeratosis, color and swellings) and ...

Somatic Cell Count During and Between Milkings [PDF]
Journal of Dairy Science, 2007 The objectives of the study were to determine 1) how sampling time between milkings affects the sensitivity and specificity of somatic cell count (SCC) as an indicator for intramammary infection (IMI) status, and 2) which cells are responsible for the diurnal variation in SCC. Six Prince Edward Island, Canada, dairy herds were selected. Quarter samples

A Lactation Measure of Somatic Cell Count
Journal of Dairy Science, 1987 Adjustments and weights to combine individual sample day SCC into a lactation measure were developed from 182,446 Holstein lactation records completed in 1984 from herds primarily in the western United States. Data included 1,660,782 sample day SCC expressed as log base 2 scores.

Italian Journal of Animal Science, 2019 The progressive decrease of mean SCC in dairy herds worldwide is affecting SCC accuracy as a subclinical mastitis marker. This evidence supports studies aiming to apply differential cell count (DSCC) as a tool to identify mastitis.

Electronic Counting of Somatic Cells in Milk
Journal of Dairy Science, 1967 Abstract Several procedures were developed and evaluated to find a satisfactory method for electronic counting of somatic cells in milk. Best results were obtained when milk was prepared for counting by a) diluting 1:50 with 0.85% saline, b) centrifuging 10ml of the diluted milk at a relative centrifugal force (RCF) of 1,020 for 15min at 4C, c ...
