Animal, 2009 A multi-trait animal model was used to estimate genetic parameters among lactation somatic cell score (SCS) and udder-type traits in South African Jersey cattle, through restricted maximum likelihood (REML) procedures.

Dairy Farmers and Veterinarians’ Agreement on Communication in Udder Health Consulting [PDF]
Veterinary SciencesUdder health consulting is an essential aspect of mastitis control and is based on herd-specific intervention often provided by the herd veterinarian, focusing on managing the bulk tank somatic cell count.

Confirmed effects of candidate variants for milk production, udder health, and udder morphology in dairy cattle. [PDF]
Genet Sel Evol, 2020 International audienceBackground: Over the last years, genome-wide association studies (GWAS) based on imputed whole-genome sequences (WGS) have been used to detect quantitative trait loci (QTL) and highlight candidate genes for important traits. However,

Somatic cell count in dairy goats II: udder health monitoring at goat and herd level [PDF]
BMC Veterinary ResearchBackground Mastitis is a costly disease affecting dairy ruminants worldwide. Somatic cell count is the most widely used tool for udder health monitoring but is highly influenced by non-infectious factors in goats.

[Analysis of udder health in relation to antimicrobial usage in Swiss dairy farms]. [PDF]
, 2019 INTRODUCTION In Switzerland, standards for milk quality are high. This requires a high level of udder health in dairy cows. Previous studies have shown that mastitis and antibiotic dry cow treatments are the most common causes of antimicrobial ...

Genetic correlations among somatic cell scores, productive life, and type traits from the United States and udder health measures from Denmark and Sweden [PDF]
, 1998 Sire genetic evaluations for protein yield, somatic cell score (SCS), productive life, and udder type traits from the US were correlated with sire evaluations for udder health from Denmark and Sweden and then the correlations were adjusted for accuracies

Effect of Overmilking on Udder Health
Journal of Dairy Science, 1982 This study evaluated the effect on udder health of extending the milking period with or without vacuum fluctuation. Eighty cows were allotted into treatment groups consisting of 1) Control milked with normal milking equipment and the milker removed as soon as milk flow ceases; 2) milked for 12 min with normal equipment; 3) milked 12 min with induced ...

Udder Health in the Periparturient Period
Journal of Dairy Science, 1988 The periparturient period is associated with rapid differentiation of secretory parenchyma, intense mammary growth, copious synthesis and secretion, and marked accumulation of colostrum and milk. Udder health during this time is an important factor associated with the production of maximum quantities of high quality milk.

Cleanliness scores as indicator of klebsiella exposure in dairy cows [PDF]
, 2008 This study was designed to explore the relationship between cow and udder cleanliness scores and the risk of isolation of Klebsiella spp. from lower hind legs and teat ends, respectively. The distribution of Klebsiella species was compared among isolates
