N-alkane profile in some plants grazed by sheep in Chilo Archipelago, Chile

Abstract

In this study, the pattern of n-alkanes of fifteen species collected in a naturalized grassland grazed by sheep in the Archipelago of Chilo, Chile was analyzed. The concentrations of odd-chain n-alkanes between C₂₃ and C₃₁ were placed on the recommended values for obtaining reliable estimates of consumption. It was also observed that species showed marked differences in their individual patterns. The results show a promising horizon to advance in determining the composition of the diet of sheep grazing in the Archipelago of Chilo (Chile).
