Deciphering ecological interactions in the ruminant gastrointestinal tract microbiota that affect methane formation and the efficacy of mitigation strategies
This project aims to investigate a pressing question regarding the mechanisms by which methane inhibitors affect individual populations of methane producing bacterium and the overall ruminal fermentation. Mantovani’s lab hypothesizes…

Demonstrating the value of dairy ingredients in protein- and fiber-based enriched snack foods
Demand is increasing for foods with high fiber and protein contents, especially bioactive proteins with health-promoting functions. An underutilized source of these nutrients is dairy whey, a byproduct of cheese…

Intramammary infusion of tannin-chitosan hydrogels for prevention or treatment of bovine mastitis
Bovine mastitis is the leading cause of infections in Wisconsin dairy herds and worldwide. Klebsiella pneumoniae and Streptococcus uberis are pathogens associated with increased incidence of clinical mastitis in Wisconsin dairy cows.…

Manure application recommendations for alfalfa interseeded into corn silage
Adequate nutrient management of forage crops is crucial to provide livestock with nutrients and energy for production and reduce risks to the environment. The dairy industry of Wisconsin relies heavily…

The use of a modified acrylic fiber for removal of copper and antibiotics from manure amended soils
To treat and prevent diseases in cows, veterinary antibiotics are routinely used in dairy operation. Unfortunately, antibiotics are only partially metabolized and can be unintentionally released onto agricultural lands during…

Beyond immunoglobulin concentrations: Exploring the potential of fresh colostrum on immune development and health in dairy calves
Calves are born immunologically naïve and depend exclusively on colostrum for transfer of immunity to confer antibody, and cell-mediated protection against environmental pathogens during the first weeks of life and…

Evaluating the effects of manure-based products on silage corn nitrogen uptake, fertilizer nitrogen use efficiency, soil nitrogen transformations, and nitrous oxide emissions
This proposed work aims to investigate the potential of processed manure to improve agricultural sustainability by addressing the challenges presented by large amounts of cattle manure. Dissolved air flocculation (DAF)…

Application of dairy components in improving chronic disease risk
The objective of this project is to propose an effective nutritional strategy that will prevent lean mass loss, after bariatric surgery in postmenopausal women. This project hypothesizes that the use…

A systematic review of the economics of nutritional interventions to reduce enteric methane production in dairy cows
Enteric methane from dairy cows is an important source of methane emissions and has been increasing more rapidly than emissions from beef production. Methods proposed to decrease enteric methane production…

Controlling ruminant methane emissions employing lactic acid bacteria and their metabolites
Lactic acid bacteria (LAB) are natural colonizers of the gastrointestinal tract of young livestock. Several LAB produce antimicrobial peptides (AMPs) and previous research indicated that LAB metabolites can reduce methane…
