Improving bovine udder health: a national mastitis control program in the Netherlands [PDF]

, 2013
Because of increasing bulk milk somatic cell counts and continuous clinical mastitis problems in a substantial number of herds, a national mastitis control program was started in 2005 to improve udder health in the Netherlands.

Genetic parameters for somatic cell score according to udder infection status in Valle del Belice dairy sheep and impact of imperfect diagnosis of infection [PDF]

, 2010
Background Somatic cell score (SCS) has been promoted as a selection criterion to improve mastitis resistance. However, SCS from healthy and infected animals may be considered as separate traits.

Physiological Aspects of Milk Somatic Cell Count in Small Ruminants—A Review

Dairy, 2022
The aim of this review was to focus on the physiological aspects of milk somatic cell count (SCC) in small ruminants (SM). The SCC is an important component naturally present in milk and is generally used as an indicator of milk quality and udder health ...

Proposal of an udder health genetic index for the Italian Holstein Friesian based on first lactation data

Italian Journal of Animal Science, 2010
Genetic correlations between udder conformation traits and SCS were estimated in Italian Holstein Friesian data. A total of 1,268,762 first parity Italian Holstein cows had information both on conformation traits and SCC. Test day SCC were transformed to

Change in Udder Health with Overmilking

Journal of Dairy Science, 1978
Removing milker units as soon as milk flow stopped was compared to milking for a fixed time of 12 min in an 8-wk trial with 60 cows. Teats were dipped in broth culture of approximately 10(9) colony forming units per ml of Staphylococcus aureus, Streptococcus agalactiae, and Streptococcus uberis for 4 wk.

Variation in udder health indicators at different stages of lactation in goats with no udder infection [PDF]

, 2014
Mastitis is an important disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose mastitis in goats are available but have not all been investigated in healthy ...

Antimicrobial resistance of Streptococcus dysgalactiae, Streptococcus agalactiae, and Streptococcus canis in quarter milk samples from Bavaria, Southern Germany, between 2012 and 2022

Journal of Dairy Science
: The objective of this study was to analyze the in vitro antimicrobial resistance (AMR) of Streptococcusdysgalactiae, Strep. agalactiae, and Strep. canis over a 10-yr period from 2012 to 2022 against the most commonly used antimicrobial agents. For this
