基　　金：酶解鱼粉(酶解鱼蛋白)在黄颡鱼饲料中的应用研究专项(P113410618)。

摘　　要：为了比较不同生产工艺得到的酶解鳀鱼浆(HFP)、鳀鱼溶浆(SW)、酶解鳀鱼溶浆(HSW)、低温烘干鳀鱼粉(L-FM)和常规烘干鳀鱼粉(H-FM)在饲料中的应用效果。以初始体质量为(17.69±0.09) g的黄颡鱼幼鱼为养殖对象,以30%的秘鲁超级蒸汽鱼粉(FM组)为对照,在实验日粮中分别添加酶解鳀鱼浆、鳀鱼溶浆、酶解鳀鱼溶浆、低温烘干鳀鱼粉和常规烘干鳀鱼粉,经过8周池塘网箱养殖实验,比较5种不同生产工艺得到的鳀鱼蛋白质原料对黄颡鱼生长性能的影响。结果显示,(1)与FM组相比,L-FM和H-FM组的特定生长率(SGR)和饲料系数(FCR)均无显著差异;(2)以FM组为对照,HFP25实验组的SGR降低了3.30%,FCR升高了5.36%,无显著差异,而HFP45和HFP65组的SGR分别降低了10.99%、20.33%,FCR分别升高了21.43%、41.96%,差异显著,并且随着日粮中HFP添加量的增加,SGR、蛋白沉积率(PRR)和脂肪沉积率(FRR)均呈现下降趋势,差异显著;(3)HFP45、SW和HSW 3组实验饲料的结果中,HFP具有最高的SGR,而SW的SGR最低,差异不显著。经酶解处理后的HSW较SW组SGR升高了2.25%,差异不显著,体组成方面,鱼体水分、蛋白、脂肪和总磷含量变化不显著,灰分变化显著。研究表明,在黄颡鱼生长性能和饲料利用效率方面,FM、L-FM和H-FM之间无显著性差异,但L-FM在黄颡鱼健康方面优于H-FM;在黄颡鱼日粮中实际添加7.1%的酶解鳀鱼浆(干物质)可以完全替代30%的鱼粉,在鱼体生长速率、饲料效率和血清指标等方面具有一定的等效性;日粮中过高添加量HFP会导致黄颡鱼生长速率和饲料效率的下降;不同酶解蛋白原料中,HFP对黄颡鱼的生长效果最好,SW生长效果最差。此外,经酶解处理后的HSW要优于SW。本实验为有效提高海洋捕捞资源的利用率,推进海洋生物蛋白新产品的开发,并为饲料企业选择更有效的产品及其使用剂量提供研究基础和应用技术。In order to compare the effects of hydrolysate fish protein of anchovy(HFP),stickwater of anchovy(SW),hydrolysate stickwater of anchovy(HSW),low-temperature fishmeal(L-FM) and high-temperature fishmeal(H-FM) by different production processes in diets,juvenile Pelteobagrus fulvidraco with an initial body weight of(17.69±0.09) g were taken as experimental subjects.30% super steam fishmeal(FM group) was used as control.HFP,SW,HSW,L-FM and H-FM were added into the test diet respectively,after 8 weeks culture experiment,the effects of 5 different production techniques of anchovy protein on growth performance of yellow catfish were compared.Among them,the addition levels of HFP in the diet were designed to be 25%(HFP25 group),45%(HFP45 group) and 65%(HFP65 group) of the protein content of fish meal in the FM group.The HFP45 group was used as the reference,and the growth of SW and HSW groups with the same protein content was compared.8experimental diets were isonitrogenous and isolipid,with 3 replicates per group and 40 fish per replicate.The results showed that,(1) taking the FM group as the control,SGR and FCR in L-FM and H-FM groups were not significantly different;(2) the SGR of HFP25 group was decreased by 3.30%,and the FCR was increased by 5.36%,showing no significant difference.SGR of HFP45 and HFP65 groups was decreased by 10.99% and 20.33%,and the FCR was increased by 21.43% and 41.96%,respectively,with significant difference.SGR,protein retention rate(PRR) and fat retention rate(FRR) showed a decreasing trend with the increase of HFP level;(3) among the three protein ingredients of HFP,SW and HSW,HFP group had the highest SGR,and SW group had the lowest SGR,with no significant difference.SGR of HSW group after hydrolysis was 2.25% higher than SW group,with no significant difference.In body composition,there were no significant differences in moisture,crude protein,crude fat and total phosphorus among HFP45,HSW and SW groups,but ash contents were significantly different.The results also showed that there were
