| 中文摘要: |
| 研究了在饲料中添加稀土壳聚糖螯合盐（ＲＥＣＣ）对水产颗粒饲料性能的影响。根据鲫（Ｃａｒａｓｓｉｕｓａｕｒａｔｕｓ）鱼苗的营养需求配制４种类型的ＲＥＣＣ试验日粮，即１号饲料（０．００％）、２号饲料（０．０８％）、３号饲料（０．１６％）和４号饲料（０２４％）。测定４种饲料的粉化率和溶失率。结果显示，添加稀土壳聚糖螯合盐后可以降低饲料的
粉化率，饲料中添加０．１６％的稀土壳聚糖螯合盐效果尤其明显（Ｐ＜０．０１）；在饲料中添加ＲＥＣＣ可以显著降低饲料的溶失率（Ｐ＜０．０５），并可以提高和改善水产颗粒饲料的性能。

| 英文摘要: |
| The effects of adding rare earth - chitosan chelate （ RECC ） on performance of aquaculture feed pellets were investigated in the present study. Based on the nutrient requirement of fingerling of Carassius auratus L. , four types of experimental rations which differed in RECC composition, 1# （RECC： 0.00% ）, 2# （RECC： 0.08% ）, 3# （ RECC ： 0. 16% ） and 4# （ RECC ： 0.24% ） were designed. Percentage of powered pellets and leaching loss of each type of rations were measured. The percentage of powered pellets were decreased through adding RECC in ration, especially with obvious effects of 0. 16% RECC （P 〈 0.01 ）. Through adding RECC in ration, the leaching loss was cut down significantly （P 〈 0.05 ）. The results indicated that the diet supplemented with RECC can enhance and improve the performance of aquatic pellets. |
