Genetic relationship of lactation persistency with milk yield, somatic cell score, reproductive traits, and longevity in Slovak Holstein cattle [PDF]
Archives Animal Breeding, 2016 The objective of this study was to estimate the breeding values (BVs) of lactation persistency, the test day of milk yield, the somatic cell score, reproductive traits (calving interval, days open), longevity in Slovak Holstein dairy cattle.

Application of a Finite Mixture Model to Somatic Cell Scores of Italian Goats [PDF]
Journal of Dairy Science, 2005 The objectives of this study were to apply a finite mixture model (FMM) to data for somatic cell count in goats and to compare the fit of the FMM with that of a standard linear mixed effects model. Bacteriological information was used to assess the ability of the model to classify records from healthy or infected goats.

Effects of Melatonin on Dairy Herd Improvement (DHI) of Holstein Cow with High SCS
Molecules, 2021 Mastitis is a common disease in cows breeding. The milk quality will be significantly reduced with increased milk somatic cells, which often occurs in cows with mastitis.

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 ...

Relationship of Somatic Cell Score with Fertility Measures
Journal of Dairy Science, 2001 Dairy Herd Improvement data from 284,450 cows in 37 states were used to examine the relationship of test-day somatic cell score, herd, calving year, parity, lactation stage, and calving ease score with fertility measures (rate of nonreturn to estrus by 70 d after first service, days to first service, and days open) for US Holsteins and Jerseys.

Genomic associations with somatic cell score in first-lactation Holstein cows [PDF]
Journal of Dairy Science, 2012 This genome-wide association study aimed to identify loci associated with lactation-average somatic cell score (LASCS) and the standard deviation of test-day somatic cell score (SCS-SD). It is one of the first studies to combine detailed phenotypic and genotypic cow data from research dairy herds located in different countries.
