Abstract The aim of this review is to discuss the usage of insect fats as an energy source in animal nutrition. Insects are a rich carrier of proteins, fat, and minerals. They are successfully introduced in animal diets (poultry, swine, rabbits, fish, and pets) as a source of many nutrients, including energy and essential fatty acids (FAs). The insects’ fat content and quality are highly affected by the type of substrate provided to the insects during the rearing period. The majority of the studies have shown that insect fats may be used as promising substitutes for conventional energy resources in animal nutrition without adverse effects on growth performance and feed utilization. They can positively affect meat quality by increasing the level of long-chain polyunsaturated FAs but may also positively influence animals by regulating the gut microbiota and stimulating the immune system. In conclusion, insect fat supplementation showed promising results in terms of their application in animal nutrition. However, compared to insect protein application, very few studies have been performed on insect fats. Therefore, because of the fat quality and content of insects, there is a need to extend experimentation regarding their implementation in animals’ diets as a replacement for conventional dietary energy resources.

动物营养中的昆虫脂肪——综述

摘要 本综述的目的是讨论昆虫脂肪作为动物营养能源的用途。昆虫是蛋白质、脂肪和矿物质的丰富载体。它们被成功引入动物饮食（家禽、猪、兔、鱼和宠物）中，作为许多营养素的来源，包括能量和必需脂肪酸 (FA)。昆虫的脂肪含量和质量在很大程度上受到饲养期间提供给昆虫的基质类型的影响。大多数研究表明，昆虫脂肪可用作动物营养中常规能源的有前途的替代品，而不会对生长性能和饲料利用产生不利影响。它们可以通过增加长链多不饱和脂肪酸的水平对肉质产生积极影响，但也可以通过调节肠道微生物群和刺激免疫系统对动物产生积极影响。总之，昆虫脂肪补充剂在动物营养方面的应用方面显示出可喜的结果。然而，与昆虫蛋白应用相比，对昆虫脂肪的研究很少。因此，由于昆虫的脂肪质量和含量，需要扩展关于它们在动物饮食中实施的实验，以替代传统的饮食能源。关于昆虫脂肪的研究很少。因此，由于昆虫的脂肪质量和含量，需要扩展关于它们在动物饮食中实施的实验，以替代传统的饮食能源。关于昆虫脂肪的研究很少。因此，由于昆虫的脂肪质量和含量，需要扩展关于它们在动物饮食中实施的实验，以替代传统的饮食能源。
