摘要

由于水产养殖的高成本和动物蛋白来源的持续短缺，开发替代植物蛋白来源一直是建立可持续水产养殖的主要挑战之一。本试验的目的是研究黄颡鱼(Tithonia varfolia)的化学成分及其对莫沙×尼罗鱼(Oreochromis mossambicus × nilochromis)幼鱼生长性能、饲料效率和代谢生化的影响。采用0(对照)、4、8、12和16%的饲料添加量，饲喂15个塑料水族箱养殖的幼鱼，密度为15只/个。实验持续8周。该粉粗蛋白质含量充足(21%)，粗脂肪含量低(4.5%)，中性洗涤纤维含量为43.03%，酸性洗涤纤维含量为24.40%。在增重、日平均增重(DAW)、体长增重(DAL)、特定生长率(SGR)、饲料效率(FE)、蛋白质效率(PER)和饲料系数(FCR)方面差异显著(p小于0.05)。添加16%黄粉处理的增重、DAW、SGR、FE和PER值(分别为15.88 g、0.28 g. day-1、2.03%、0.34 g. day-1和0.98)与对照处理无显著差异，表明黄粉处理具有显著的增效作用。代谢生化指标随黄颡鱼粉添加量的增加而降低，其中甘油三酯、胆固醇和葡萄糖含量以对照处理最高(p <0.05)，而蛋白质含量则增加到面粉的4%。大黄粉在化学成分和氨基酸方面营养均衡，对生长性能、体长关系、饲料效率、成活率和代谢生化没有负面影响。

Chemical composition of Tithonia diversifolia (Hemsl.) and its effect on growth performance, feed efficiency and metabolic biochemistry of juvenile hybrid tilapia Oreochromis mossambicus × Oreochromis niloticus

The aquaculture due to the high cost and continued shortage of animal protein sources, the development of alternative plant protein sources has been one of the main challenges to establish sustainable aquaculture as economically viable. Objective of this investigation was to determine the chemical composition and effect of Tithonia diversifolia on the growth performance, feed efficiency and metabolic biochemistry of juveniles of Oreochromis mossambicus × Oreochromis niloticus. Five treatments were used: 0% (control), 4, 8, 12 and 16% levels of inclusion of T. diversifolia flour in diet to feed juvenile fish cultured in 15 plastic aquariums at a density of 15 fish/aquarium. The assay lasted eight weeks. The T. diversifolia flour was characterized for showing adequate levels of crude protein (21%), with low crude fat (4.5%) levels, neutral detergent fiber levels: 43.03% and acid detergent fiber: 24.40%. The growth performance presented significant differences (p˂0.05), for weight gain, day average weight gain (DAW), length gain, day average length gain (DAL), specific growth rate (SGR), feed efficiency (FE), protein efficiency ratio (PER) and feed conversion ratio (FCR). In treatment with 16% of inclusion of T. diversifolia flour, values obtained for weight gain, DAW, SGR, FE and PER (15.88 g, 0.28 g. day-1, 2.03 %, 0.34 g.g-1 and 0.98, respectively), which did not differ with the control treatment, highlighting the benefits of T diversifolia flour. The metabolic biochemistry parameters experienced a decrease with the increase of T. diversifolia in diet, where the highest values of triglycerides, cholesterol, and glucose were for the control treatment (p <0.05), while the protein increased to 4% of the flour. T. diversifolia flour presents an adequate balance of nutrients for its chemical composition and amino acids, without causing negative effects on the growth performance, weight-length relationship, feed efficiency, survival and metabolic biochemistry.

期刊介绍： Notulae Botanicae Horti Agrobotanici Cluj-Napoca is a peer-reviewed biannual journal aimed at disseminating significant research and original papers, critical reviews and short reviews. The subjects refer on plant biodiversity, genetics and plant breeding, development of new methodologies that can be of interest to a wide audience of plant scientists in all areas of plant biology, agriculture, horticulture and forestry. The journal encourages authors to frame their research questions and discuss their results in terms of the major questions of plant sciences, thereby maximizing the impact and value of their research, and thus in favor of spreading their studies outcome. The papers must be of potential interest to a significant number of scientists and, if specific to a local situation, must be relevant to a wide body of knowledge in life sciences. Articles should make a significant contribution to the advancement of knowledge or toward a better understanding of existing biological and agricultural concepts. An international Editorial Board advises the journal. The total content of the journal may be used for educational, non-profit purposes without regard to copyright. The distribution of the material is encouraged with the condition that the authors and the source (Notulae Botanicae Horti Agrobotanici Cluj-Napoca or JCR abbrev. title Not Bot Horti Agrobo) are mentioned.
