• Resumen

  • The aim of this study was to estimate liposoluble vitamins in the milk of the ewe and the meat of the suckling lambs in two management systems (grazing vs. stall-fed with hay) and the addition of condensed tannins in the ewe’s diet (with 7,5% vs. 0%). In milk, a-tocopherol and retinol concentrations were detected but lutein and ȕ-carotene were undetectable. Retinol and Į-tocopherol concentrations in milk were higher in grazing than in stall-fed ewes (P<0.05). The addition of condensed tannins affected differently retinol and a-tocopherol in milk, with no clear effect. Regarding meat, only Į-tocopherol was detected. Grazing lambs had greater Į-tocopherol content in muscle than stall-fed sukling lambs P<0.05). The addition of condensed tannins affected Į-tocopherol content in meat (P=0.05). In conclusion, Į-tocopherol was affected by the management and condensed tannins addition in the ewe’s diet, being the most suitable tracer of the diet received.
