The genetic determinants of gastrointestinal tract colonization by Listeria monocytogenes
Listeria monocytogenes (Listeria) is a dangerous foodborne pathogen commonly associated with dairy product outbreaks. Listeria infection has remarkably high hospitalization and mortality rates, thus the FDA implements a zero-tolerance policy for…

Selection for resilient dairy cows
This project seeks to improve the health and welfare of dairy cows and the sustainability of dairy farms by genetic selection for resistance to, and rapid recovery from, environmental and…

Buccal swabbing as a molecular tool for rumen microbial profiling and diagnosis in dairy cattle
A healthy and optimal rumen microbiome is critical to the wellbeing of highly productive dairy cows. Current methods for rumen sampling are invasive, laborious, and infeasible for large herds. A…

Galactooligosaccharides (GOS) synthesized from lactose as milk supplement to promote probiotic growth
This project intends to synthesize galactooligosaccharides (GOS) from lactose as a cow milk supplement to promote probiotic growth and improve gut health in humans. GOS is a major component in…

Comparing the efficacy of EGTA and 5-HTP induction and resolution of hypocalcemia in dairy cows
Hypocalcemia, which causes lethargy and death if left untreated, is a common and pervasive disease in the dairy industry. Research has shown that inducing transient hypocalcemia prepartum causes a resistance…

Green ammonia recovery from manure digester and lagoon by electrodialysis
Human expansion and intervention in the nitrogen cycle has led to a “lossy” system, particularly in manure handling. The ammonium ion is moveable using electrical fields similar to electrodialysis. This…

Efficacy of manure nutrient prediction and variable rate technology to improve nutrient use efficiency on Wisconsin dairy farms
Manure is a valuable resource for maintaining soil fertility on Wisconsin dairy farms. However, over-application causes soils to become saturated with nutrients, which can lead to surface and groundwater contamination.…

High-speed refrigerated floor centrifuge dedicated to understanding antibiotic resistance in Listeria monocytogenes isolates from dairy cattle and dairy farms (Biological Safety Level-2)
Huyng’s project will use a high-speed refrigerated floor centrifuge dedicated for Biological Safety Level-2 work. This is essential for research to understand and circumvent antibiotic resistance in Listeria monocytogenes, which…

A centralized histology and microscopy software resource to disentangle gene-environmental interactions that drive fetal programming and nutrient partitioning in the dairy cow
Leone’s project will develop a centralized DIH Histology and Microscopy Resource to be used with histology and microscopy equipment, software modules, a live-cell CO2 imaging stage, and a cryostat, to…

Biochemistry Analyzer to test if residues remaining after milk processing can be microbially fermented into valuable products
Donohue’s project will utilize a YSI Model 2980-D2 Biochemistry Analyzer. This Biochemistry Analyzer allows rapid, direct, and simultaneous quantification of residue sugars (lactose, galactose, glucose), nitrogenous compounds (ammonia and several…
