不同饵料对管角螺生长、肝脏消化酶活性及软体部营养成分的影响
Effect of different diets on growth, digestive enzymes activities in liver and nutritional composition in visceral mass of Hemi-fusus tuba Gmelin
摘要
Abstract
Effects of three different diets, including Sinonovacula constricta(A), Meretrixie linnaeus(B) and for-mulated diet(C) on the growth,digestive enzymes activities and nutritional composition in sceral mass of two-year-old Hemifusus tuba Gmelin were studied. The results showed that:(1) the live feed was more conducive to H. tuba Gmelin growth and accumulation of nutritional, and the C feeding effects was more poorer and need further optimization and perfection;the SGR was significantly different among the experiment groups (P<0.05), group A>group B>group C;(2) the digestive enzymes activities in liver of H. tuba Gmelin were significantly different by feeding different diets. The specific activities of trypsin were significantly different among the experiment groups (P<0.05), group A>group B>group C;the specific activities of amylase and lipase were first decreased and then increased, but the live feed groups were much more stable; the specific activities of amylase and lipase were sig-nificantly higher than live feed groups (P<0.05), suggesting there might be compensatory secretion of digestive enzymes, and glucose and fat were utilized preferentially when H.tuba Gmelin was hungered; (3) no significant difference in moisture content and crude ash in visceral mass among the experiment groups (P>0.05), the crude protein and the crude fat content of live feed groups were significantly higher than that of the group C (P<0.05).关键词
