Assessment of low amounts of meat and bone meal in the diet of laying hens by using stable isotopes
(Semina-ciencias Agrarias, 2015-01-01) [Artigo]
The aim of this study was to assess whether the inclusion of low amounts of ingredients such as wheat bran, corn gluten and yeast in the diet of laying hens can interfere with the traceability of meat and bone meal (MBM) ...
Traceability of animal by product meals in broilers fed sugarcane yeast using stable isotopes
(Revista Brasileira de Ciência Avícola, 2012-03-01) [Artigo]
The objective of this study was to verify if the dietary inclusion of sugarcane yeast at levels commonly used in broiler diets influences the traceability of cattle meat meal and poultry offal meal, using the technique of ...
Studies on carbon-13 turnover in eggs and blood of commercial layers
(Revista Brasileira de Ciência Avícola, 2006-10-01) [Artigo]
This paper aimed at evaluating the influence of diets containing different isotopic values of carbon-13 turnover on the half-life of egg (yolk + albumen), yolk and albumen individually, and blood of poultry using δ‰ 13C ...
Carbon isotope fractionation for cotton genotype selection
(Pesquisa Agropecuária Brasileira, 2014-09-01) [Artigo]
The objective of this work was to evaluate the carbon isotope fractionation as a phenomic facility for cotton selection in contrasting environments and to assess its relationship with yield components. The experiments were ...
Traceability of bovine meat and bone meal in poultry by stable isotope analysis
(Revista Brasileira de Ciência Avícola, 2006-03-01) [Artigo]
Bovine meat and bone meal (MBM) was widely used in animal diets until outbreaks of Bovine Spongiform Encefalopathy (BSE) occurred in some countries. It has not been confirmed yet whether or not BSE may be transmitted to ...

(Food Science and Technology (Campinas), 2013-03-01) [Artigo]
Os objetivos deste trabalho foram utilizar o método de análise isotópica para quantificar o carbono do ciclo fotossintético C3 em néctares de maçã comerciais e mensurar o limite de legalidade para identificar as bebidas ...
The use of stable isotopes for authentication of gadoid fish species
(European Food Research and Technology, 2011-01-01) [Artigo]
The rise of processed seafood in international trade has increased the feasibility of fish species substitution. Gadidae fish species are sold commercially as salted fish, and differences in price between fish of different ...
Growth and photosynthetic down-regulation in Coffea arabica in response to restricted root volume
(Functional Plant Biology, 2006-01-01) [Artigo]
Coffee (Coffea arabica L.) plants were grown in small (3-L), medium (10-L) and large (24-L) pots for 115 or 165 d after transplanting (DAT), which allowed different degrees of root restriction. Effects of altered source : ...
