Dr. Ferreira is originally from Buenos Aires, Argentina, where his family manages a cropping and beef cow/calf farm. Dr. Ferreira obtained a degree in Agricultural Engineering from Universidad Católica Argentina (1998). Ever since he was an undergraduate student, Dr. Ferreira has always been fascinated with forage management and cattle nutrition. Because of this, immediately after graduation Dr. Ferreira performed a research internship at the USDA-Dairy Forage Research Center located in Madison, WI. As he became strongly engaged with research, Dr. Ferreira pursued a Master of Science degree in Dairy Nutrition from University of Wisconsin-Madison (2002) and a PhD degree in Dairy Nutrition from The Ohio State University (2006). After working 2 years in the industry as a technical manager for DSM Nutritional Products Argentina SA, Dr. Ferreira worked 5 years as a technical and management consultant for dairy farmers in Asociación Argentina de Consorcios Regionales de Experimentación Agrícola (AACREA). Since August, 2013, Dr. Gonzalo Ferreira has been a Dairy Management Extension Specialist in the Department of Dairy Science at Virginia Tech.

Dairy Financial Management. When attending some (if not all) of his workshops, you will hear from Dr. Ferreira that the most effective means for improving farm profitability and ensuring farm sustainability is discussing farming as a business. Since 2015, Dr. Ferreira has been delivering educational workshops about dairy enterprise management to dairy farmers. These workshops intend to build a holistic management strategy to help farmers to successfully manage their agricultural operations through periods of high risk, volatility, and financial stress. This holistic management strategy implies developing a strategic plan, building financial balance sheets and budgets, analyzing partial budgets and capital investments, and analyzing marketing or pricing strategies. These educational workshops have been delivered in several regions within Virginia and several States throughout the nation.

Forage Quality and Management. Dr. Ferreira’s extension program focuses heavily on forage quality and management. For this program, Dr. Ferreira delivers educational on-farm workshops and produces diverse extension fact-sheets and educational videos. He also writes popular press articles in several magazines, such as Hoard’s Dairyman, Hay & Forage Grower, and Dairy Herd Management among others.

Labor Management. Dr. Ferreira is convinced visual and hands-on learning experiences accelerate the learning processes of employees. As such, Dr. Ferreira develops educational videos, some of them in Spanish with scripts in English, to improve the training process of the labor force of dairy farms.

Applied Dairy Nutrition. Dr. Ferreira’s research program evaluates how agronomic practices and abiotic stresses affect the nutritional composition of forages, as well as dairy cattle production performance and nutrient utilization. Dr. Ferreira’s laboratory also investigates the effects of B-vitamin supplementation on performance and metabolism in dairy cattle.

Although Dr. Ferreira does not have a teaching appointment, he lectures in a few courses of the Department of Dairy Science, such as and Applied Dairy Cattle Nutrition and Advance Dairy Management Evaluation (also known as Dairy Challenge).
