Conference and Workshop Presentations Tutorials Lectures

The Media webpage brings together resources on applied ruminant nutrition modeling, including conference and workshop presentations on model adequacy, development of mathematical models for predicting animal performance, and tools for individual cattle management and small ruminants. It also offers step-by-step tutorials for installing and using the GasFit System, GnG1 models, the Ruminant Nutrition System, and the Beef Cattle Nutrient Requirements Model (2016).

In addition, the page hosts a lecture series on rumen microbiology and its role in ruminant nutrition, covering topics from microbial diversity and metabolism to ruminal disorders and strategies to manipulate rumen fermentation. A free-of-charge copy of Dr. Jim Russell's Rumen Microbiology and its Role in Ruminant Nutrition can be downloaded here.

Conference and Workshop Presentations

1. Assessment of the Adequacy of Mathematical Models (outline, full screen, pdf). This seminar was firstly presented on June 3rd, 2004 at the Model Evaluation Symposium at the Sassari University in Sassari, Italy and on November 21-22, 2006 at the 3rd Workshop on Adaptation of the CNCPS to Tropical Conditions at the Dairy Research Unit of the Brazilian Agricultural Research Company in Juiz de Fora, Brazil.

2. Development of Mathematical Models to Estimate Animal Performance and Feed Biological Value (outline, full screen, pdf). This seminar was presented on March 8-10, 2007 at the 1st International Symposium on Advanced Techniques in Ruminant Nutrition at the University of Sao Paulo/FMVZ in Pirassununga, São Paulo, Brazil.

3. Development and Evaluation of Models to Assist Individual Cattle Management (outline, full screen, pdf). This seminar is a combination of several presentations performed at different meetings, including Beef Improvement Federation and National Beef Cattle Evaluation Consortium.

4. Development and Evaluation of Nutrition Models for Domesticated Small Ruminants: The SRNS (outline, full screen, pdf). This seminar was presented on July 22-25, 2008 at the Brazilian Society of Animal Science annual meeting in Lavras, Minas Gerais, Brazil and on August 31-September 5, 2008 at the International Conference on Goats, Queretaro, Mexico.
