Characterizing the behavior and management of dairy cows and neonate calves shortly after birth
Despite advancements in nutrition and epidemiology, dairy cows remain at high risk of disease after giving birth. A main gap in our knowledge is the optimal housing environment for these…

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…
-
Utilization of plasma activated water (PAW) as a clean-in-place (CIP) sanitizer for surface disinfection of dairy processing equipment
Dairy products are susceptible to microbial contamination and spoilage. Equipment surfaces of manufacturing machinery in the dairy processing line are the main source of biological contamination of processed milk. Contamination…

Developing novel and sustainable disease management strategies against Aphanomyces root rot of alfalfa
Alfalfa is the most widely grown forage legume in the United States and is used for hay and silage. Although many cultivars that are grown in Wisconsin are relatively hardy,…

Evaluating nitrogen availability from solid-liquid-separated and composted manure
Manure is often applied to land to return organic matter and nutrients to the soil. Manure processing methods, such as solid-liquid-separation and composting, have grown in popularity to improve transport…

Full implementation of automated rotational grazing and assessment of its impact on animals and on forage
Pasture systems are an effective and potentially economical way to produce feed for livestock, but grazing management can be a challenge. Previous Hub-funded research developed two prototype systems, physical and…
