2012 NMC Scholars Selected
Students awarded travel scholarships to attend NMC 51st annual meeting
The National Mastitis
Research Foundation (NMRF) board of directors named Amanda Sterrett,
University of Kentucky; Roxann Weix, University of Wisconsin-Madison;
Diana Sorg, Technische Universitt Mnchen, Germany; and Joren Verbeke,
Ghent University, Belgium, as the 2012 National Mastitis Council (NMC)
Scholars. These graduate students posses a strong interest in mastitis
control, udder health and quality milk production. NMRF, through the
NMC Scholars program, provides funding for these students to attend
and participate in NMC's 51st Annual Meeting, January 22-24, 2012, in
St. Pete Beach, Florida. The goal of the NMC Scholars Program is to
support the development of future milk quality researchers and specialists.
Working on her master's degree, Sterrett completed a comprehensive assessment
of management practices related to low somatic cell count in Kentucky.
Her master's research also included using precision dairy technologies
to monitor dairy cow health and behavior. This project will help determine
the effectiveness of precision dairy technologies and evaluate relationships
between data from each technology and ambient weather information. For
her doctorate dissertation, Sterrett plans to use these technologies
to monitor cow behavior and health - particularly mastitis. The purpose
of this project is to determine the effectiveness of precision dairy
technologies in identifying illnesses before clinical signs are observed
in order to understand the physiology behind diseases.
A veterinarian pursuing a master's degree, Weix practiced veterinary
medicine for two years in private practice as a dairy cattle and small
ruminant practitioner. While in practice, she implemented milk quality
and mastitis control programs for several dairy herds and one goat dairy.
Weix's current research focuses on identifying management practices
on organic and conventional dairies that improve animal health and well-being,
with a strong emphasis on milk quality, including milking procedures,
mastitis definitions and perceptions, mastitis treatments and procedures,
individual animal milk cultures, bulk tank cultures and quality, and
records of mastitis cases. She enjoys working with dairy producers to
implement milk quality programs and troubleshoot milk quality challenges.
Sorg, a doctoral candidate, is studying the innate immune response of
primary bovine mammary gland epithelial cells to the mastitis pathogens
Escherichia coli and Staphylococcus aureus on gene expression and protein
secretion level. Her research compares the immune response of two modern
dairy breeds - Brown Swiss and Red Holstein in Germany - to two rare
and valuable ancient breeds - White Park and Highland cattle in the
United Kingdom. These two ancient breeds are known for their phenotypical
resistance to mastitis. She hopes to find clues about possible genetic
factors for mastitis resistance. These genetic factors could then be
used for genomic selection in dairy cattle.
Pursuing a doctorate degree, Verbeke's research focuses on two genes
and their relation to dairy heifer udder health, particularly better
prevention of heifer mastitis. The major goal is to analyze to what
extent mutations in the CXCR1 and CXCR2 genes explain variability in
innate immunity of the udder and susceptibility toward mastitis pathogens
of early lactating heifers. This information could be used in selecting
highly productive and more sustainable dairy cattle. As a veterinary
student, Verbeke performed research on mastitis in Jimma, located in
southeast Ethiopia. This research focused on the relationship between
micromineral status and mastitis in urban dairy farms.
