Rodrigo Alexis Arias

Ingeniero Agrónomo, M.Sc., Ph.D

 

Rodrigo A. Arias Inostroza, es Profesor Asociado de la Facultad de Ciencias Agrarias y Alimentarias de la Universidad Austral de Chile (UACh). Además, es Director del Programa de Doctorado en Ciencia Agrarias y forma parte del Consejo de Escuela de Agronomía. Es miembro activo de la Sociedad Chilena de Producción Animal y lidera el grupo de Ganadería, Salud y Sustentabilidad.

Estudió Técnico Universitario en Producción Agrícola, Pontificia Universidad Católica de Chile, es Ingeniero Agrónomo de la Universidad Católica de Temuco y M.Sc. y Ph.D. in Animal Science (nutrición de rumiantes), Minor in Statistics, University of Nebraska-Lincoln, USA.

Su investigación se ha centrado en la relación entre los factores climáticos, la nutrición y la calidad de los productos (carne de res y leche) y su efecto en la salud de las personas. Otra área de interés son los efectos de los sistemas de producción alimentados con pasto sobre el balance de nitrógeno y las emisiones de metano entérico. Ha realizado y colaborado en proyectos financiados por Fondecyt, FIC, UACh-Virginia Tech, CONICYT, Global Research Alliance y Norman E. Borlaug International Agricultural Science and Technology Fellowship Program, entre otros.

En pregrado es responsable de las asignaturas Producción de Carne Bovina, Mejoramiento Animal, Producción Animal Avanzada y Nutrición de rumiantes. Además, colabora en Fisiología Animal, Taller de Sistemas, Producción Animal y Relación Suelo-Planta-Animal, entre otras.

Agronomist, M.Sc., Ph.D

 

Rodrigo Arias is an Associate Professor at the Institute of Animal Production, Faculty of Agricultural and Food Sciences, Universidad Austral de Chile (UACh). He is also Director of the Doctorate Program in Agricultural Science and is a member of the Council of the School of Agronomy. He is an active member of the Chilean Society of Animal Production and leads the Livestock, Health and Sustainability group.

 

He obtained the degree of University Technician in Agricultural Production from Pontificia Universidad Católica de Chile and his Bachelor´s degree from Universidad Católica de Temuco. He earned both his M.Sc. and Ph.D. in Animal Science (ruminant nutrition), Minor in Statistics, from the University of Nebraska-Lincoln (USA).

 

His research focuses on the relationship between climatic factors, nutrition and the quality of products (beef and milk) and their effect on people's health. He also studies the effects of grass-fed production systems on nitrogen balance and enteric methane emissions. He has led and collaborated in projects funded by Fondecyt, FIC, UACh-Virginia Tech, CONICYT, Global Research Alliance and Norman E. Borlaug International Agricultural Science and Technology Fellowship Program, among others.

 

He is responsible for teaching the subjects of Bovine Meat Production, Animal Improvement, Advanced Animal Production, and Ruminant Nutrition at undergraduate level. He also collaborates with the modules of Animal Physiology, Systems Workshop, Animal Production and Soil-Plant-Animal Relationship, among others.
