Abstract
Shrimps with an initial weight of 11.10 ± 0.26 g were fed diets supplemented with 6.6% red pepper (RP), 2.4% marigold flower (MF), and 100 mg/kg synthetic astaxanthin (SA), each of which contained 100 mg/kg total carotenoid, and a control diet (BD), without carotenoid supplement for 60 days. Dietary carotenoid sources did not significantly affect the growth of the shrimps (P > 0.05). SA supplementation yielded the highest survival rate (92%), followed by RP (82%) and the other diets (75%) (P < 0.05). All dietary carotenoid sources provided higher carotenoid accumulation compared to the control group (P < 0.05), but the difference between them was not significant (P > 0.05). RP and SA resulted in a greater protein increase in shrimp muscle than MF (P < 0.05); however, lipid, ash, and water content were similar in all diet groups (P > 0.05).
Özet
Bafllang›ç a¤›rl›¤› 11,10 ± 0,26 g olan karidesler her biri 100 mg/kg karotenoyit içeren % 6,6 k›rm›z› biber (RP), % 2,4 kadife çiçe¤i (MF), 100 mg/kg sentetik astaksantin (SA) ve karotenoyit içermeyen kontrol grubu (BD) diyetleriyle 60 gün beslenmifllerdir. Karotenoyit kaynaklar›n›n karideslerin büyümesi üzerine bir etkisi olmam›flt›r (P > 0,05). En yüksek yaflama oran›n› SA diyeti (% 92) göstermifl ve bunu s›ras›yla RP (% 82) ve di¤er diyetler (% 75) izlemifltir (P < 0,05). Tüm karotenoyit katk›l› gruplar kontrol grubuna göre daha fazla karotenoyit birikimi sa¤lam›fl (P < 0,05), ancak kendi aralar›nda önemli bir farkl›l›k bulunmam›flt›r (P > 0,05). RP ve SA karideslerin kas dokusunda MF’ ye göre daha fazla bir protein art›fl›na neden olmufltur (P < 0,05). Lipit, ham kül ve su miktarlar› ise tüm diyet gruplar›nda benzer bulunmufltur (P > 0,05).
