中文摘要:
      本文讨论了饲料中蛋白质和醣含量对青鱼鱼种生长的影响。试验饲料由酪蛋白、糊精、鱼肝油、羧甲基纤维素粉(CMC)、无机盐混合剂和适量的维生素组成。用于试验的青鱼鱼种的平均体重为37.12—48.32克,试验期间的水温为24—34℃,试验得到的数据,经统计分析表明,青鱼鱼种饲料的最适蛋白质含量为29.54—40.85%。饲料中蛋 质和醣含量之间存在着明显的交互作用,当蛋白质含量为37—43.3%,醣含量为9.5—18.6%时,青鱼鱼种生长最快。饲料的蛋白质含量对鱼体的蛋白质、脂肪和醣含量有一定影响,肝脏中蛋白质含量也受到饲料蛋白质含量的影响,肝醣含量则随饲料醣含量的增加而增加。饲料中蛋白质和醣的含量会影响青鱼鱼种的消化率,当饲料中蛋白质处于最适量而醣含量在30%以下时,鱼的蛋白质消化率大致为92%左右,醣含量过高将对蛋白质的消化率产生影响。饲料的组成对青鱼鱼种的血红蛋白含量影响不大。
英文摘要:
      This paper deals with the effects of protien and carbohydrate contents in feedson the growth of black carp (Mylopharyngodon piceus) fingerlings. The experimentalfeeds were composed of casein, dextrin,fish-liver oil, powder of carboxymethylcellulose, mix-mineral and suitable amount of vitamins. The black carp fingerlingsused in the experiment were 37.12--48.32 grams in average weight, and rearedunder water temperature of 24--34℃ for eight weeks.Computing by straight--line regression and parabolic regression indicates that theoptimal proportion of protien in the feed should be 29.54--40.85%. The interactionbetween protien and carbohydrate is obvious. When the fingerling were given with afeed containing 37--43.3% of protien and 9.5--18.6% of carbohydrate, the fishgrow very fast. Therefore, the content of carbohydrate in the feed for black carpfingerlings about 20% seems to be suitable.The protien content in feed directly affects the content of protien, fat and car-bohydrate in fish body and the liver. The liver starch of fish is increseased with the increase of carbohydrate content in the feed.The digestive rate of protien in black carp fingerlirgs is affected by the quantityof carbohydrate contents in the feed. When carbohydrate content below 30% in feed,the protien digestive rate can be kept at 92%; while the carbohydrate content wasincreased to 43%, the protien disgestive rate will be greatly decreased. The reason ofit may be that black carp is carnivorous.The hemoglobin of black carp fingerlings was measured. Except the starvedgroup is 5 g hem./100 ml all the rest groups are 5.8--6.5g hem./100ml. It is believedthat the composition of feed makes little effect on hemoglobin level of black carpfingerlings.
