Abstract

The purpose of this study was to investigate the change of hematology and serum chemistry values on Sprague-Dawley rats, while used krill (Euphausia superba) meal diet for 5 weeks. Seven-week-old male rats were divided into four groups (n=6) and fed experimental diets containing three different krill meal contents and control group; 10.0% krill meal (G10), 20.0% krill meal (G20), 30.0% krill meal (G30), and control group (GC). Concentrations of non-esterified fatty acid (NEFA), blood urea nitrogen (BUN) in serum were significantly lower in the G10, G20, G30 than GC group (p<0.05). Statistically significant differences, at the confidence level of 95%, for the creatinine, uric acid, electrolyte (T-Ca) parameters in the sera were observed in G20 group, G30 group. The concentration of electrolyte (Pi) in serum was no significant difference among the groups (p<0.05). The results indicate that a krill meal diet was effectively reduce the NEFA.

본 연구는 식이조성에 동결 건조한 krill (Euphausia superba) meal을 첨가 하였을 때 Sprague Dawley계 수컷 흰쥐의 유리지방산(non-esterified fatty acid, NEFA), blood urea nitrogen(BUN), creatinine, uric acid 및 전해질에 미치는 영향에 대하여 조사를 하였다. 식이조성은 기본식이를 급여한 대조군인 GC군(krill meal 미함유)을 비롯하여 기본식이에 10.0%, 20.0%, 30.0%의 krill meal 급여군을 각각 G10군, G20군, G30군으로 구분하였다. 5주간 실험 사육한 결과, 흰쥐의 NEFA와 BUN 농도는 krill meal 급여군(G10군, G20군, G30군)에서 대조군(GC 군)보다 유의적으로 감소된 결과를 보였고, creatinine과 uric acid 농도는 G10군에서는 GC군과 유의적 차이가 없었으나, G20군과 G30군에서 유의적으로 감소하였다(p<0.05). 전해질 농도에서 total calcium (T-Ca)은 G20군과 G30군에서 유의적으로 증가하였으며, 인(Pi) 농도는 각 군간에 유의적 차이가 없는 것으로 관찰되었다(p<0.05).
