The Evaluation Of Feed Additives On Reducing Enteric Methane Production From Cattle, Reba L. Colin

Department of Animal Science: Dissertations, Theses, and Student Research

Environmental sustainability can be positively impacted by the inclusion of feed additives to reduce enteric methane production from cattle. Methane production can be affected by feed additives that either alter the rumen environment or act as methanogenesis inhibitors. A reduction in methane from cattle can contribute to meeting carbon neutrality.

A metabolism study was conducted to evaluate Alga 1.0, a product containing bromoform, fed to cattle to evaluate the effects on gas emissions. Treatments were (0, 69, or 103 g/d Alga 1.0) fed in a corn-based diet. Headbox-style indirect calorimeters were used to measure gas emissions. Feeding Alga 1.0 linearly …

The Effects Of Sous Vide Cooking And Cysteine Proteases On Instrumental And Sensory Textural Properties Of Lower Value Cuts Of Beef, Ian Smith

All Theses

Sous vide cooking has the potential to increase the value of lower quality cuts of beef. Understanding the textural properties following a cook-chill sous vide process is crucial to maximizing this potential. The use of enzymes may further increase the value of these products if able to positively alter the texture of the final product.

The first research objective was to use instrumental texture analysis to evaluate potential relationships between enzymatic treatments and sous vide processing time of lower value cuts of beef. Three cuts were evaluated: infraspinatus (top blade), semitendinosus (eye of round), and beef tongue. Infraspinatus and semitendinosus …

Profiling The Cell Wall Polysaccharides Of Hemp (Cannabis Sativa L.) Inflorescence And Hempseed And Exploring Their Application As Ruminant Feed Ingredients, Miranda Agbana

Theses and Dissertations--Animal and Food Sciences

Hemp (Cannabis sativa L.) is used in the United States as a source of CBD oil, fiber, and grain. While hempseeds are consumed whole or as dehulled hemp hearts, hempseed oil is also a desirable seed oil in human nutrition. The process of collecting hempseed oil leaves behind hempseed cakes that are abundant in protein and fiber. Feeding of hempseed cakes to animals, including ruminants, has only initially been explored. Extraction of CBD from hemp inflorescences generates organic waste that may find a second purpose as a fiber feed for cattle. Little is known about the exact fiber composition …

Potentials Of Pleurotus: Reimagining The Relationship Between Cattle And Brewer's Spent Grain, Zoe Stojkovic

Senior Projects Spring 2023

Brewer’s spent grains (BSGs), a byproduct from beer production, are generated in excess globally. Most often, they are sold or given to proximate cattle farmers for use as feed. However, spent grain can also be used as a medium for fungal cultivation. Given that certain fungal species have the capability to degrade lignin and produce protein, the cultivation of fungi on spent grains may serve to enhance the nutritional profile of the grains for their use as cattle feed. This project is an effort to determine the compatibility of fungal cultivation with BSGs in order to both improve upon cattle …
