Differential Leukocyte Count Method for Bovine Low Somatic Cell Count Milk [PDF]
Journal of Dairy Science, 2003 Whereas many differential leukocyte count methods for high somatic cell count (SCC) milk from mastitic cows are available, only a few have been developed for low SCC milk. We have developed a flow cytometric differential leukocyte count method for low SCC milk. The procedure consists of 1) 1.5 ml of diluted milk sample (30%, vol/vol dilution with PBS),

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.

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

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 ...

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.

Models to Estimate Lactation Curves of Milk Yield and Somatic Cell Count in Dairy Cows at the Herd Level for the Use in Simulations and Predictive Models [PDF]
, 2016 Typically, central milk recording data from dairy herds are recorded less than monthly. Over-fitting early in lactation periods is a challenge, which we explored in different ways by reducing the number of parameters needed to describe the milk yield and

Impact of Early Lactation Somatic Cell Count in Heifers on Somatic Cell Counts Over the First Lactation [PDF]
Journal of Dairy Science, 2004 The objective of this study was to estimate the impact of somatic cell count in early lactation (SCCel) from Belgian dairy heifers on test-day somatic cell count (SCC) in first lactation. Geometric mean SCCel [5 to 14 d in milk (DIM)] of the 14,766 available samples was 104,000 cells/mL, and decreased from 178,000 at 5 DIM to 74,000 cells/mL at 14 DIM.

Impact of policy-induced structural change on milk quality : evidence from the Flemish dairy sector [PDF]
, 2009 This paper uses a Markov chain model to analyse the dynamics in farm size distribution among the Flemish dairy sector and the impact of quota policy regulation on such changes.
