摘要

研究了在尼罗罗非鱼日粮中用东方卫矛粉（WM）替代0、25、50、75和100%的鱼粉（FM）对生长性能、饲料效率和健康状况的影响。随机选取 15 尾幼鱼（平均体重为 1.1 克 ± 0.02），喂食试验饲料 84 天。研究结果表明，当 FM 被高达 50%的 WM 部分替代时，鱼的生长速度没有受到明显影响。WM25 和 WM50 的饲料转化率大大高于其他日粮。用 WM 替代 FM 至 100%，对总蛋白、球蛋白、白蛋白、尿素、肌酐、丙氨酸氨基转移酶和天门冬氨酸氨基转移酶的值没有明显改变（）。这些结果表明，尼罗罗非鱼不会因添加高达 50%的 WM 而受到影响，也不会对生长和营养利用产生不利影响。

Influence of substituting fishmeal with Vespa orientalis meal in the Nile tilapia (Oreochromis niloticus) diets on growth and feed utilisation

The impact on growth performance, feed efficiency, and health status of substituting 0, 25, 50, 75, and 100% of fishmeal (FM) with Vespa orientalis meal (WM) in the Nile tilapia diets was examined. Fifteen hapas of randomly selected fingerlings (with a mean weight of 1.1 g ± 0.02) were fed the test meals for 84 days. The findings indicated that the fish development rate was not noticeably affected when FM was partially replaced by up to 50% of WM. The feed conversion ratios of WM25 and WM50 were considerably greater () than those of all other diets. The substitution of FM by WM up to 100% did not significantly alter the values of total protein, globulin, albumin, urea, creatinine, alanine aminotransferase and aspartate aminotransferase (). These results suggest that the Nile tilapia is unaffected by the integration of WM up to 50% instead of FM without adverse effects on growth and nutrient utilisation.

期刊介绍： The Journal of Insects as Food and Feed covers edible insects from harvesting in the wild through to industrial scale production. It publishes contributions to understanding the ecology and biology of edible insects and the factors that determine their abundance, the importance of food insects in people’s livelihoods, the value of ethno-entomological knowledge, and the role of technology transfer to assist people to utilise traditional knowledge to improve the value of insect foods in their lives. The journal aims to cover the whole chain of insect collecting or rearing to marketing edible insect products, including the development of sustainable technology, such as automation processes at affordable costs, detection, identification and mitigating of microbial contaminants, development of protocols for quality control, processing methodologies and how they affect digestibility and nutritional composition of insects, and the potential of insects to transform low value organic wastes into high protein products. At the end of the edible insect food or feed chain, marketing issues, consumer acceptance, regulation and legislation pose new research challenges. Food safety and legislation are intimately related. Consumer attitude is strongly dependent on the perceived safety. Microbial safety, toxicity due to chemical contaminants, and allergies are important issues in safety of insects as food and feed. Innovative contributions that address the multitude of aspects relevant for the utilisation of insects in increasing food and feed quality, safety and security are welcomed.
