I. Gonzalez-martin et al., Differentiation of dietary regimene of Iberian swine by means of isotopic analysis of carbon and sulphur in hepatic tissue, MEAT SCI, 58(1), 2001, pp. 25-30
The aim of this work was to differentiate the feed received by Iberian swin
e during fattening (acorns, feed) and their breed (Iberian or White) using
analysis of the stable isotopes of carbon (delta C-13) and sulphur (delta S
-34) in liver tissue samples. The results obtained in the determination of
delta S-34, using a procedure in which organic and inorganic sulphur are co
nverted into BaSO4 and the procedure that measures delta S-34 in samples of
dried ground liver tissue were compared. Joint analysis of carbon (delta C
-13) and sulphur (delta S-34) permits the differentiation of swine of diffe
rent breeds receiving different diets (acorns or feed). (C) 2001 Elsevier S
