以室内养殖刀鲚为试验对象,研究20天的短期饥饿对其形体、体成分和血液生化指标的影响,实验组分别在第0、2、5、10、15和20天取样。结果表明,脏体比和肝体比在饥饿的第2天即显著下降(P<0.05),肥满度和体质量在20天的饥饿期内呈下降趋势,但变化不显著(P>0.05)。刀鲚肌肉粗脂肪在第5天显著下降(P<0.05),下降5.99%,而粗蛋白含量在第15天时才显著降低(P<0.05),水分在整个饥饿期间总体呈上升趋势,第10天显著上升(P<0.05),粗灰分含量在饥饿期间变化不显著(P>0.05)。血清总蛋白、球蛋白、胆固醇和皮质醇随着饥饿时间的延长呈现先升高后降低的趋势,而血清甘油三酯和血糖总体呈先急速下降并维持一定水平,其中甘油三酯在饥饿至第2天显著下降(P<0.05),血糖浓度在第5天显著下降(P<0.05)。表明短期饥饿胁迫使刀鲚形体发生一定的变化,随着饥饿时间的延长,刀鲚首先先动用体内储存的脂肪来满足能量供应,再动用蛋白质来维持体内的正常代谢,血液生化指标也发生与饥饿相适应的变化。 |
英文摘要: |
This study was carried out to determine the effect of starvation on body appearance,muscle composition and blood biochemistry of the Coilia nasus which were cultivated with the indoor condition in 20 days. The experimental groups were sampled on 0 day (control), 2 days, 5 days, 10 days and 20 days. The results showed: there was a significant(P<0.05) trend to decline for hepatosomatic index and andviserosomatic index in the 2nd day, while the effect of obese relative and body weight were not different(P>0.05)in the 20th day. There was a significant (P< 0.05) trend to decline for the crude fat in the body muscle of the Coilia nasus for 5.99% on the 5th day, while the trend of body contents of crude protein declined in the 15th day. During the period of starvation ,there was a significant(P<0.05) trend to increase for contents of moisture in the 10th day while content of crude ash does not change significantly(P>0.05). With the starvation time extending, serum total protein, globulin, cortisol and cholesterin present a trend of increasing,then decreasing while serum triglycerides and glucose fell sharply and maintain a certain level which triglycerides decrease significantly in the 2nd day (P<0.05) and blood glucose decrease significantly in the 2nd day (P<0.05).The experiment illustrated that the Coilia nasus body appearance had changed,and with the prolongatin of starvation, the muscle fat was decompose to exploit first, the muscle protein then to be used, at the same time, the body biochemical of the Coilia nasus was changed to be fit for the starvation condition. |
