Since 1985, researcher at CENA/USP for technical assistance in ruminant production and sustainability using tracers and correlated techniques:
- in vitro gas test (syringes and transducers) for evaluating feed, co-products, residues and identification of potential use of tannins and other plants secondary metabolites rich plants for ruminants;
- in vivo quantification of enteric methane production (chambers and SF6 tracer) on studies of grazing and fibrous residues for ruminants and strategies to intensify the sustainable ruminant production.
- use of tracers for quantify ruminal microbial mass (15N and purine derivatives) and feed constituents (δ13C and δ 15N);
- writing research projects scientific papers, including literature review, experimental design and statistical support;
