The effects of fatty aci̇d composi̇ti̇on of the roti̇fer (brachionus plicatilis) some commerci̇al enri̇chi̇ng products commi̇ned whi̇t l-carni̇ti̇ne

In this thesis, it was determinated of the effect on fatty acid contens of rotifer (Brachionus plicatilis) of suplemented of L-carnitine to Algamac 3050, Red Pepper. S. parkle was used as feed in mass culture of B. plicatilis. Rotifer was applied feeding combined of commercial products suplemented with S. parkle (group I; control), S. parkle+ Red Pepper (group II), S. parkle+ Red Pepper+ L - karnitin (group III), S. parkle+ L - karnitin (group IV), S. parkle+ Algamac 3050 (group V), S. parkle+ Algamac 3050 + L - karnitin (group VI). Considerable differences were found in fatty acid composition of B. plicatilis fed with commercial enrichment diets. The highest EPA and PUFA; were determinated enriched with S. parkle + Algamac 3050 + L – karnitin in rotifer at the end of the trial, at 12 hour, the highest DHA were determinated enriched with S. parkle + Algamac 3050 + L - karnitin in rotifer at the end of the trial, at 6 hour. The enrichment duration was found significant (P< 0,05) effect of PUFA content of rotifers.
