Ahead of the NSW state election on 25 March 2023, the NSW Government caretaker period has commenced. Limited updates will be made to this website during this period.
ALVARENGA, Flavio
Research interests
- Beef / sheep productivity and efficiency at pasture
- Livestock behaviour and sensor technologies
- Feeding strategies and pasture management to improve meat quality and profitability
- Impact of mycotoxins and insufficient magnesium in beef cattle.
Background
Flavio Alvarenga is currently Research Officer (Grazing efficiency) – Extensive Livestock unit of NSW Department of Primary Industries. He graduated in Animal Science (UFVJM, Brazil) and developed his Masters and Doctoral studies in animal production and nutrition (UFLA and UFMG).
Dr. Alvarenga has been working with animal supplementation at pasture and its effect on growth rate, grazing behaviour, biometric measures, rumen wall evaluation and carcass traits. Currently he is involved in a multi-component, interdisciplinary project that aims to improve feed efficiency by developing new traits for genetic selection of cattle including behaviour, intake and efficiency at pasture. Also developing an understanding of the contribution of these traits to efficiency of grazing cattle.
Qualifications
- Doctor of Animal Science (Federal University of Minas Gerais - UFMG)
- Master of Animal Science (Federal University of Lavras - UFLA)
- Bachelor of Animal Science (Federal University of Vales of Jequitinhonha and Mucuri - UFVJM)
Current and past projects
- Productivity and efficiency at pasture: Development and application of sensor technologies and livestock phenomics facilities for enhanced productivity and efficiency at pasture
- Supplementation to reduce the impact of mycotoxins and insufficient magnesium in beef cattle
