Abstract

This study aimed to understand the effects of various energy-protein ratios of feed on nilem carp fish (Osteochilus hasselti) growth. This study was conducted from September to October 2017 at the Laboratory of Building 4, Faculty of Fisheries and Marine Sciences, Universitas Padjajaran. The average size of the test fish was ± 7 cm with an average weight of 3 grams. This was a Completely Randomized Design (CRD) experimental study consisting of 5 treatments and 3 repetition. The treatments given were 5 feed formulas based on different feed protein energy ratios, i.e. treatment A (31% protein, ratio 10), treatment B (31% protein, ratio 8), treatment C (28% protein, ratio 10), D (28% protein, ratio 8), and E (30% protein commercial feed/control). Feed, 5% of the test fish total weight, was provided 3 times a day. Parameters observed were daily growth rate, feed conversion, and survival. Data gained were analyzed using F-test, followed by Duncan Test if differences were found between treatments. Results showed that growth rate and feed conversion of all treatments were not different compared to control. The highest result was found in treatment A (31% protein, ratio 10) with a daily growth rate of 3.99% and feed conversion of 1.95%.

不同饲料能量-蛋白质比条件下尼龙鱼的生产性能
本研究旨在了解不同饲料能量蛋白比对鲤鱼生长的影响。该研究于2017年9月至10月在帕德贾兰大学渔业与海洋科学学院4号楼实验室进行。试验鱼的平均尺寸为±7厘米,平均重量为3克。这是一项完全随机设计(CRD)实验研究,包括5个处理和3个重复。试验采用5种不同饲料蛋白能比的饲料配方,即处理A(31%蛋白质,比例为10)、处理B(31%蛋白质,比例为8)、处理C(28%蛋白质,比例为10)、D(28%蛋白质,比例为8)和E(30%蛋白质商品饲料/对照)。饲料按试验鱼总重的5%饲喂,每天3次。观察参数为日生长率、饲料转化率和成活率。所得数据采用f检验进行分析,如果发现治疗间存在差异,则采用Duncan检验。结果表明,各处理的生长率和饲料系数与对照组相比无显著差异。以A处理(蛋白质含量为31%,比例为10)效果最好,日生长率为3.99%,饲料系数为1.95%。
