摘要

研究目的:有关大菱鲆(Scophthalmus maximus Linnaeus, 1758)饮食需求的研究主要集中在幼鱼阶段;然而,有关较大(300-500 克)鱼种的研究并不多。本实验的目的是确定大菱鲆理想的蛋白质、脂肪和碳水化合物膳食水平。研究区域土耳其安塔利亚德姆雷。材料与方法创建了一个由三部分组成的混合设计模型,以调整日粮蛋白质含量在 45.6% 到 63.4% 之间,碳水化合物含量在 4.9% 到 30.5% 之间,脂肪含量在 5.6% 到 17.7% 之间。该模型的组成成分为鱼粉(FM)、鱼油(FO)和小麦粉(W)。最初平均体重为(301.6±0.1)克的鱼喂食 14 种不同的日粮,为期 10 周。通过检查预测剖析器,根据最终体重、日生长系数、蛋白质效率比、氮和能量保留最大化,以及饲料转化率、氮和碳损失最小化等变量,估算出最理想的日粮主要营养素水平。主要结果在所有选定的反应中,最佳日粮配方的可取性最高,为 0.87,日粮中 FM、W 和 FO 的含量分别为 63.6%、20.8% 和 9.4%。针对大菱鲆(生长 300 至 500 克)提出的最佳营养浓度为干物质基础上 54%的蛋白质、约 17%的脂质和 15.8%的碳水化合物。研究亮点:通过混合设计,我们成功地估算出了大菱鲆日粮中蛋白质、脂质和碳水化合物的最佳含量。

Use of a mixture design to optimize dietary macronutrients for large turbot (Scophthalmus maximus Linnaeus, 1758)
Aim of study: Studies on the dietary needs of turbot fish (Scophthalmus maximus Linnaeus, 1758) have largely focused on the juvenile stage; however, there are not many on the larger (300–500 g) species. The purpose of this experiment was to determine the ideal dietary levels of protein, fat, and carbohydrate for large turbot. Area of study: Demre, Antalya, Türkiye. Material and methods: A three-component mixture design model was created to adjust the quantities of dietary protein between 45.6% and 63.4%, carbohydrates between 4.9% and 30.5%, and fat between 5.6% and 17.7%. The components of the model were fish meal (FM), fish oil (FO), and wheat flour (W). Fish initially weighing 301.6±0.1 g on average were fed 14 different diets for 10 weeks. The ideal dietary macronutrient levels were estimated by examining the prediction profiler at the highest desirability based on the variables that were selected to maximize final weight, daily growth coefficient, protein efficiency ratio, nitrogen and energy retentions, and minimize feed conversion ratio, nitrogen and carbon losses. Main results: The optimal diet formulation yielded the highest desirability of 0.87 for all selected responses and resulted in dietary inclusion levels of FM, W and FO as 63.6%, 20.8%, and 9.4%, respectively. The proposed optimal nutrient concentrations for large turbot (growing from 300 to 500 g) are 54% protein, approximately 17% lipid, and 15.8% carbohydrate on dry matter basis. Research highlights: The mixture design successfully allowed us to estimate the optimum levels of dietary protein, lipid and carbohydrate for large turbot.

期刊介绍: The Spanish Journal of Agricultural Research (SJAR) is a quarterly international journal that accepts research articles, reviews and short communications of content related to agriculture. Research articles and short communications must report original work not previously published in any language and not under consideration for publication elsewhere. The main aim of SJAR is to publish papers that report research findings on the following topics: agricultural economics; agricultural engineering; agricultural environment and ecology; animal breeding, genetics and reproduction; animal health and welfare; animal production; plant breeding, genetics and genetic resources; plant physiology; plant production (field and horticultural crops); plant protection; soil science; and water management.
