Fig. 3. The hierarchical cluster analysis (Euclidean distance clustering algorithm) according
to the feeding systemand gene expression in L. thoracis muscle (a) and subcutaneous
fat (b) of Rasa Aragonesa lambs. The colour represents the level of expression. The names
of genes and treatments are indicated. ALF: lambs grazing alfalfa; VE10d: lambs received
basal concentrate supplemented with α-tocopherol during the last 7–14 days; VE20d:
lambs received basal concentrate supplemented with α-tocopherol during the last
18–25 days; VE30d: lambs received basal concentrate supplemented with α-tocopherol
during the last 29–36 days; C: control lambs.
