Table 3.7. gives a comparison of the protein content of rotifers enriched with three
different enrichment strategies (A: long term enrichment during the culture with baker’s
yeast + 10% Super Selco®; B: short term enrichment with DHA-Selco®; C: short term
enrichment with Protein Selco®). Dry weight is significantly higher in rotifers enriched with
Protein Selco® and similar for A and B. The protein level is significantly higher for C than B
rotifers, but no significant difference can be observed between the protein level of A and C
rotifers. Lipid levels are significantly higher for C than for A rotifers, but no difference can
be found between C and B rotifers. A rotifers have the highest protein/lipid ratio and B the
lowest ratio (∅ie et al., 1996).
