摘要: The effect of prebiotic xylooligosaccharides (XOS) on the growth performance and digestive enzyme activities of the allogynogenetic crucian carp, Carassius auratus gibelio, was investigated. XOS was added to fish basal semi-purified diets at three concentrations by dry feed weight: diet 1, 50 mg kg(-1); diet 2, 100 mg kg(-1); diet 3, 200 mg kg(-1), respectively. Twelve aquaria (n = 20) with three replicates for each treatment group (diets 1-3) and control treated without XOS were used. Weights of all collected carp from each aquarium were determined at the initial phase and at the end of the experiment, and the carp survival was also determined by counting the individuals in each aquarium. After 45 days, there were significant differences (P < 0.05) in the relative gain rate (RGR), and daily weight gain (DWG) of diets 1-3 were compared with the control. However, the survival rate was not affected (P > 0.05) by the dietary treatments. For enzymatic analysis, dissection produced a crude mixture of intestine and hepatopancreas of each segment to measure. The protease activity in the intestine and hepatopancreas content of fish in diet 2 (487.37 +/- A 20.58 U g(-1) and 20.52 +/- A 1.93 U g(-1)) were significantly different (P < 0.05) from that in the control (428.13 +/- A 23.26 U g(-1) and 12.81 +/- A 1.52 U g(-1)) and diet 3 (428.00 +/- A 23.78 U g(-1) and 14.04 +/- A 1.59 U g(-1)). Amylase activity in the intestine was significantly higher for diet 2 compared to diet 1 and the control. As for amylase in the hepatopancreas, assays showed higher activity in diet 2 (P < 0.05) compared to the rest.
