Definitions
- feed additive according to the present invention or a feed comprising such feed additive is administered to an animal, the administration thereof results in a desired level of muscle retention in said animal.
- the desired level of the carotenoid retained in the muscle leads to a pleasant, consumer-appealing flesh color similar to wild counterparts.
- Carotenoids are organic pigments ranging in color from yellow to red that are naturally produced by certain bioorganisms, including photosynthetic organisms (e.g., plants, algae, bacteria such as cyanobacteria), and some fungi. Carotenoids are responsible for the orange color of carrots, as well as the pink color in flamingos and salmon, and the red color in lobsters and shrimp. Animals, however, cannot produce carotenoids and must receive them through their diet. Carotenoid pigments (e.g. ⁇ -carotene and astaxanthin) are used industrially as ingredients for food and feed stocks, both serving a nutritional function and enhancing consumer acceptability.

- Fillets are taken from the 10 fish closest to the average weight of each replicate tank. Fillet color is analyzed in 3 replicate locations within 1-2 hours of euthanasia using a Minolta chroma meter. Color readings are taken of the Norwegian Quality Cut (NQC) region (Fig. 1) approximately identified by each number in Fig. 2. Readings are taken for mean redness, yellowness, lightness, hue, and chroma (see Table 5).
- NQC Norwegian Quality Cut
- NQC samples are taken from the 10 selected fillets.
