Abstract
An 8‐week growth trial investigated the effect of dietary lipid level on growth performance of a carnivorous fish, Chinese longsnout catfish (Leiocassis longirostris Günther) and an omnivorous fish, gibel carp (Carassius auratus gibelio). For each species, seven isonitrogenous semi‐purified diets (455 g kg−1 crude protein for Chinese longsnout catfish and 385 g kg−1 crude protein for gibel carp) were formulated to contain 30, 60, 90, 120, 150, 180 or 210 g kg−1 lipid. For Chinese longsnout catfish, feed intake (FI) decreased with increasing dietary lipid and there was no significant difference in feed intake from 90 to 210 g kg−1 lipid. Specific growth rate (SGR) increased with dietary lipid level (P < 0.05) and the 150 and 180 g kg−1 groups were the best. Feed conversion efficiency (FCE), protein retention efficiency (PRE) and energy retention efficiency (ERE) were higher at 180 g kg−1 lipid. For gibel carp, FI decreased with increased dietary lipid and 180 and 210 g kg−1 lipid groups showed lower values. SGR increased with dietary lipid level and the 150 and 180 g kg−1 were the best. FCE was higher at 180 g kg−1 lipid level. PRE increased with dietary lipid level and there was no significant difference in groups from 120 to 210 g kg−1 dietary lipid. ERE increased with increasing dietary lipid level, and groups fed 120, 150 and 180 g kg−1 lipid showed the highest values. In Chinese longsnout catfish, increase in dietary lipid level, resulted in increased carcass dry matter, crude protein, crude lipid and gross energy. In gibel carp, dry matter, crude protein, and crude lipid increased with dietary lipid level. Based on regression between SGR and dietary lipid, dietary lipid requirements for Chinese longsnout catfish and gibel carp were 142.6 and 140.5 g kg−1, respectively.

SGR increased with dietary lipid level and the 150 and 180 g kg<sup>−1</sup> were the best. FCE was higher at 180 g kg<sup>−1</sup> lipid level. PRE increased with dietary lipid level and there was no significant difference in groups from 120 to 210 g kg<sup>−1</sup> dietary lipid. ERE increased with increasing dietary lipid level, and groups fed 120, 150 and 180 g kg<sup>−1</sup> lipid showed the highest values. In Chinese longsnout catfish, increase in dietary lipid level, resulted in increased carcass dry matter, crude protein, crude lipid and gross energy. In gibel carp, dry matter, crude protein, and crude lipid increased with dietary lipid level. Based on regression between SGR and dietary lipid, dietary lipid requirements for Chinese longsnout catfish and gibel carp were 142.6 and 140.5 g kg<sup>−1</sup>, respectively.</p></abstract></abstractGroup></contentMeta></header></component></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Comparative study on the effect of dietary lipid level on growth and feed utilization for gibel carp (Carassius auratus gibelio) and Chinese longsnout catfish (Leiocassis longirostris Günther)</title></titleInfo><titleInfo type="abbreviated" lang="en"><title>Effect of dietary lipid level on growth</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Comparative study on the effect of dietary lipid level on growth and feed utilization for gibel carp (Carassius auratus gibelio) and Chinese longsnout catfish (Leiocassis longirostris Günther)</title></titleInfo><name type="personal"><namePart type="given">Z.</namePart><namePart type="family">Pei</namePart><affiliation>State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, The Chinese Academy of Sciences, Wuhan, Hubei, China</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">S.</namePart><namePart type="family">Xie</namePart><affiliation>State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, The Chinese Academy of Sciences, Wuhan, Hubei, China</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">W.</namePart><namePart type="family">Lei</namePart><affiliation>State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, The Chinese Academy of Sciences, Wuhan, Hubei, China</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">X.</namePart><namePart type="family">Zhu</namePart><affiliation>State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, The Chinese Academy of Sciences, Wuhan, Hubei, China</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Y.</namePart><namePart type="family">Yang</namePart><affiliation>State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, The Chinese Academy of Sciences, Wuhan, Hubei, China</affiliation><role><roleTerm type="text">author</roleTerm></role></name><typeOfResource>text</typeOfResource><genre type="article" displayLabel="article"></genre><originInfo><publisher>Blackwell Science Ltd</publisher><place><placeTerm type="text">Oxford, UK</placeTerm></place><dateIssued encoding="w3cdtf">2004-08</dateIssued><edition>Received 13 December 2002, accepted 27 October 2003</edition><copyrightDate encoding="w3cdtf">2004</copyrightDate></originInfo><language><languageTerm type="code" authority="rfc3066">en</languageTerm><languageTerm type="code" authority="iso639-2b">eng</languageTerm></language><physicalDescription><internetMediaType>text/html</internetMediaType><extent unit="figures">2</extent><extent unit="tables">5</extent></physicalDescription><abstract lang="en">An 8‐week growth trial investigated the effect of dietary lipid level on growth performance of a carnivorous fish, Chinese longsnout catfish (Leiocassis longirostris Günther) and an omnivorous fish, gibel carp (Carassius auratus gibelio). For each species, seven isonitrogenous semi‐purified diets (455 g kg−1 crude protein for Chinese longsnout catfish and 385 g kg−1 crude protein for gibel carp) were formulated to contain 30, 60, 90, 120, 150, 180 or 210 g kg−1 lipid. For Chinese longsnout catfish, feed intake (FI) decreased with increasing dietary lipid and there was no significant difference in feed intake from 90 to 210 g kg−1 lipid. Specific growth rate (SGR) increased with dietary lipid level (P < 0.05) and the 150 and 180 g kg−1 groups were the best. Feed conversion efficiency (FCE), protein retention efficiency (PRE) and energy retention efficiency (ERE) were higher at 180 g kg−1 lipid. For gibel carp, FI decreased with increased dietary lipid and 180 and 210 g kg−1 lipid groups showed lower values. SGR increased with dietary lipid level and the 150 and 180 g kg−1 were the best. FCE was higher at 180 g kg−1 lipid level. PRE increased with dietary lipid level and there was no significant difference in groups from 120 to 210 g kg−1 dietary lipid. ERE increased with increasing dietary lipid level, and groups fed 120, 150 and 180 g kg−1 lipid showed the highest values. In Chinese longsnout catfish, increase in dietary lipid level, resulted in increased carcass dry matter, crude protein, crude lipid and gross energy. In gibel carp, dry matter, crude protein, and crude lipid increased with dietary lipid level. Based on regression between SGR and dietary lipid, dietary lipid requirements for Chinese longsnout catfish and gibel carp were 142.6 and 140.5 g kg−1, respectively.</abstract><subject lang="en"><genre>keywords</genre><topic>body composition</topic><topic>Carassius auratus gibelio</topic><topic>feed utilization</topic><topic>growth</topic><topic>Leiocassis longirostris Günther</topic><topic>lipid level</topic></subject><relatedItem type="host"><titleInfo><title>Aquaculture Nutrition</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">1353-5773</identifier><identifier type="eISSN">1365-2095</identifier><identifier type="DOI">10.1111/(ISSN)1365-2095</identifier><identifier type="PublisherID">ANU</identifier><part><date>2004</date><detail type="volume"><caption>vol.</caption><number>10</number></detail><detail type="issue"><caption>no.</caption><number>4</number></detail><extent unit="pages"><start>209</start><end>216</end><total>8</total></extent></part></relatedItem><identifier type="istex">209285CD2BEB83BE69AABAE334FDA550E74B63C2</identifier><identifier type="DOI">10.1111/j.1365-2095.2004.00291.x</identifier><identifier type="ArticleID">ANU291</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Science Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
