ALVARENGA, Tharcilla

Tharcilla Alvarenga

Research interests

  • Development of technologies to predict animal maturity and meat eating quality.
  • Maternal nutrition affecting meat quality traits of the progeny.
  • Manipulation of omega-3 in red meat.
  • Feeding strategies to improve meat quality.
  • Carcass traits and meat quality of lambs/beef under feedlot and grazing systems.

Background

Tharcilla Alvarenga is currently Development Officer – Extensive Livestock unit of NSW Department of Primary Industries. She is graduated in Animal Science (UFVJM, Brazil) and developed her Master and Doctoral studies in Meat Science (UNESP and UFLA, Brazil).

Currently Tharcilla is developing a multidisciplinary research project to investigate the potential of using a spectroscopy to accurately predict animal maturity and meat quality by scanning hides and muscles. Also, she works with scientists assisting in the transfer of knowledge from current R&D projects with focus on the value chain.

Qualifications

  • Bachelor of Animal Science, UFVJM 2008.
  • Master of Animal Science, UNESP 2011.
  • Doctor of Animal Science, UFLA 2015.

Current and past projects

  • Use of spectroscopy to estimate beef and sheep maturity and meat quality.
  • Novel dual purpose perennial cereals for grazing – performance, carcass and meat quality of lambs.
  • Eating quality in Merino breeding programs.
  • Influence of maternal nutrition on meat quality traits of the progeny.
  • Effect on lamb meat of supplementing with calcium soap fatty acids.
  • Expression of genes encoding enzymes regulating fat metabolism in sheep.
  • Use of oldman saltbush as a feeding strategy for sheep.
  • Carcass traits and meat quality of lambs under feedlot and grazing systems.
