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.

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.

Determination of milk production losses and variations of fat and protein percentages according to different levels of somatic cell count in Valle del Belice dairy sheep [PDF]
, 2018 The somatic cell count (SCC) of milk is widely used to monitor udder health and the milk quality and because of its positive genetic correlation with mastitis this trait was included in breeding schemes of dairy sheep.

THE EFFECT OF BLOOD AND MILK SERUM ZINC CONCENTRATION ON MILK SOMATIC CELL COUNT IN DAIRY COWS
Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine, 2016 The objective of this study was to evaluate the effect of blood and milk zinc concentration on somatic cell count and occurrence of subclinical mastitis cases.

Somatic Cell Count, Importance and Effect Factors in Dairy Cattle
Turkish Journal of Agriculture: Food Science and Technology, 2014 The somatic cell count (SCC) is commonly used as a measure of udder health and milk quality. Thus, to determine the milk quality standards in many countries, it legally determined as an indicator of somatic cell count raw milk and determines the level of

Prediction of bulk tank somatic cell count violations based on monthly individual cow somatic cell count data [PDF]
Journal of Dairy Science, 2015 The regulatory limit in Canada for bulk tank somatic cell count (BTSCC) was recently lowered from 500,000 to 400,000 cells/mL. Herd indices based on changes in cow somatic cell count over 2 consecutive months (e.g., proportion of healthy or chronically infected cows, cows cured, and new intramammary infection rate) could be used as predictors for BTSCC

Monitoring of monthly SCC in she-camel in relation to milking practice, udder status and microbiological contamination of milk [PDF]
, 2013 Somatic cell counts and bacteriological examinations were measured in 28 camel milk samples from 2 farms, one with milking machine (farm A) and the second with hand milking (farm B).
