| dc.description.abstract | The present study aimed to extract astaxanthin from shrimp waste and evaluate the
influence of dietary astaxanthin (AX) on the growth performance and pigmentation of
Whiteleg shrimp (Litopenaeus vannamei). Shrimp waste discarded from processing plants
was treated and processed to recover astaxanthin extract. Shrimp, initial body weight 1.47-
1.50g, allocated into 21 units of the 120L-glass tank, divided into seven groups, three
replicates for each, and a density of 20 shrimps per tank. Shrimp were fed with seven
experimental diets supplemented with varying levels of astaxanthin extract (0, 40, 60, 80,
100, 120, and 150mg/kg) for 60 days. The results indicated that a bioprocess was built to
extract astaxanthin from shrimp waste, which was processed through weighing, washing,
extraction, and drying to collect astaxanthin extract containing 0.38% astaxanthin, 93%
moisture, and 2.32% protein. In addition, shrimp fed the experimental diets supplemented
with 120-150mg/kg diet astaxanthin had significantly higher growth (P < 0.05) than those
of the control diet. Particularly, shrimp fed with 80–150mg/kg diet astaxanthin exhibited
higher pigmentation scores of the whole body than those fed the other diets. Overall, the
findings revealed that astaxanthin extract from shrimp waste is a potential feed ingredient
to improve the growth and pigmentation of Whiteleg shrimp. | en_US |
