三种肉骨粉替代鱼粉对乌鳢幼鱼生长的影响
Effects of meat and bone meals from three origins on growth performance of juvenile snakehead ( Ophiocephalus argus)
摘要
Abstract
Snakehead juveniles with mean initial body weight of 13. 31 0. 11 g were fed with four isonitrogenous (45. 0% crude protein) and isoenergetic (16. 5 kJ/g energy) practical diets ( D1—D4) in pond net cages for 8 weeks to study the effects of meat and bone meals (MBMs) from three origins on growth performance of juvenile snakehead (Ophiocephalus argus). Dl without MBM was the control, while D2—D4 were formulated with MBMs from Australia, Uruguay or China origins replacing 30% fish meal protein, respectively. The results showed that the specific growth rate (SGR) of fish from Dl was significantly higher than those of D3 and D4 groups, while no significant differences were found between those of fish from Dl and D2, and D4 induced the lowest SGR. No significant differences were found between feed coefficient ratios ( FCR) of fish from D3 and D4, which were significantly higher than Dl and D2 groups. Protein efficiency ratio had an inverse trend as FCR. No significant differences were found among condition factor, viscerasomatic index and hepatosomatic index from fish fed the experimental diets. Feeding effect of MBM from Australia origin on snakehead juvenile is superior to those of MBMs from Uruguay and China origins in the present study.关键词
