Abstract

This experiment was conducted to evaluate the chemical composition of Antarctic Krill (Euphausia superba Dana) meal as feed, and to investigate the effect of its supplementation on productivity and egg quality of laying hen. A total of 216 layers at the age 43 weeks in commercial cage were fed for 6 weeks with 3 different diets containing 0, 1, and 2% Krill meal (KM). The chemical composition of KM was consisted of moisture 8.25%, crude protein 50.52%, crude fat 16.67%. crude ash 15.72%, indicating that KM contains large amount of protein and fat. Krill meal also contains large amounts of mineral (15.72%), astaxanthin (l0ppm) and cholesterol (780ppm). No differences were found in egg production, broken and soft eggs, and feed intake among treatments. Dietary supplementation of KM resulted in increased egg yolk height (6.1mm) and yolk color (2) compared with those of control, suggesting that KM can be used as a feed additive for yolk quality improvement. According to the results of this study, Krill meal can be supplemented in laying hen diets as protein and fat sources, and natural coloring pigment.
