Abstract

The aim of the present study was to evaluate the effect of maize replacement by crude biodiesel-derived glycerol on the zootechnical performance, chemical carcass composition and blood parameters of silver catfish (Rhamdia quelen) juveniles. A total of 600 silver catfish juveniles were distributed in a completely randomized design with six treatments comprised of isoproteic and isoenergetic pelleted diets with six levels of glycerol replacing maize, and five replicates. The glycerol maize substitution significantly influenced (p < 0.05) the final weight, clean trunk production and headless carcass yield, with the highest values for both parameters observed in the 100% substitution treatment, significantly different compared to the 0% replacement treatment. Plasmatic calcium, alkaline phosphatase, glucose, total proteins, oxaloacetic and pyruvic glutamic transaminase concentrations were not influenced (p < 0.05) by the dietary treatments, nor were moisture, crude protein and mineral matter (p < 0.05). Crude glycerol can be included in up to 7.5% in juvenile silver catfish diets. Biodiesel-derived glycerol can, thus, successfully replace maize in juvenile silver catfish diets.

从生物柴油中提取的甘油可替代银鲴幼鱼（Rhamdia quelen）日粮中的玉米。

本研究旨在评估用粗生物柴油衍生的甘油替代玉米对银鲴幼鱼（Rhamdia quelen）的动物学性能、胴体化学成分和血液参数的影响。共 600 尾银鲴幼鱼被分配在一个完全随机设计的六个处理中，包括等蛋白和等能量的颗粒饲料，六个水平的甘油替代玉米，五个重复。甘油替代玉米显著影响（p < 0.05）最终体重、净躯产量和无头胴体产量，100%替代处理的这两个参数值最高，与 0% 替代处理相比差异显著。质钙、碱性磷酸酶、葡萄糖、总蛋白、草酰乙酸和丙酮酸谷氨酸转氨酶浓度不受日粮处理的影响（p < 0.05），水分、粗蛋白和矿物质也不受日粮处理的影响（p < 0.05）。在银鲴幼鱼日粮中，粗甘油的含量可高达 7.5%。因此，生物柴油衍生甘油可成功替代银鲶幼鱼日粮中的玉米。

期刊介绍： The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence. Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
