Abstract The high-intensity sweeteners (HIS) have intense sweetness at very low doses and provide low- or no-calories. The HIS have been widely used in animal feed to improve palatability and stimulate voluntary feed intake in farm animals, especially for animals during critical periods (i.e. post-weaning period). Although several preference tests showed a clear preference of pigs or cattle for HIS, the inconsistent results across studies make it difficult to reach conclusive remarks. The different responses to HIS could be related to the differences in animal species, genetic variation, stress, nutritional status, type and dose of HIS used, and methodology of preference test. Dietary supplementation with HIS could improve the feed intake and growth performance of pigs and ruminants by improving the palatability of feed, but the duration and doses of supplementation seem critical for those effects of HIS. Additionally, dietary supplementation with HIS could improve intestinal development, glucose absorption, and reduce the intestinal injury. These beneficial effects are most likely related to the HIS-induced intestinal glucagon-like peptide 2 secretion. Lastly, the natural HIS, neohesperidin dihydrochalcone and stevioside, exhibited the ability to promote the growth of beneficial gut bacteria in pigs and broilers, which could contribute to the improvement of gut health. Overall, the current review is to provide an overview of the effects of HIS on farm animal performance and their mechanisms of action. An attempt was made to point out the gaps of knowledge deserving future research.

超越甜味:高强度甜味剂和农场动物

摘要 高强度甜味剂 (HIS) 在非常低的剂量下具有强烈的甜味,并提供低热量或无热量。HIS 已广泛用于动物饲料中,以提高农场动物的适口性和刺激自愿采食量,尤其是在关键时期(即断奶后时期)的动物。尽管多项偏好测试显示猪或牛对 HIS 的明显偏好,但研究结果不一致使得难以得出结论性意见。对 HIS 的不同反应可能与动物种类、遗传变异、应激、营养状况、使用的 HIS 类型和剂量以及偏好测试方法的差异有关。在日粮中添加 HIS 可以通过改善饲料的适口性来提高猪和反刍动物的采食量和生长性能,但补充的持续时间和剂量似乎对 HIS 的这些影响至关重要。此外,膳食补充剂 HIS 可以改善肠道发育、葡萄糖吸收并减少肠道损伤。这些有益作用很可能与 HIS 诱导的肠道胰高血糖素样肽 2 分泌有关。最后,天然 HIS、新橙皮苷二氢查尔酮和甜菊糖苷具有促进猪和肉鸡肠道有益细菌生长的能力,有助于改善肠道健康。总体而言,当前的审查旨在概述 HIS 对农场动物性能及其作用机制的影响。试图指出值得未来研究的知识差距。膳食补充 HIS 可改善肠道发育、葡萄糖吸收并减少肠道损伤。这些有益作用很可能与 HIS 诱导的肠道胰高血糖素样肽 2 分泌有关。最后,天然 HIS、新橙皮苷二氢查尔酮和甜菊糖苷具有促进猪和肉鸡肠道有益细菌生长的能力,有助于改善肠道健康。总体而言,当前的审查旨在概述 HIS 对农场动物性能及其作用机制的影响。试图指出值得未来研究的知识差距。膳食补充 HIS 可改善肠道发育、葡萄糖吸收并减少肠道损伤。这些有益作用很可能与 HIS 诱导的肠道胰高血糖素样肽 2 分泌有关。最后,天然 HIS、新橙皮苷二氢查尔酮和甜菊糖苷具有促进猪和肉鸡肠道有益细菌生长的能力,有助于改善肠道健康。总体而言,当前的审查旨在概述 HIS 对农场动物性能及其作用机制的影响。试图指出值得未来研究的知识差距。这些有益作用很可能与 HIS 诱导的肠道胰高血糖素样肽 2 分泌有关。最后,天然 HIS、新橙皮苷二氢查尔酮和甜菊糖苷具有促进猪和肉鸡肠道有益细菌生长的能力,有助于改善肠道健康。总体而言,当前的审查旨在概述 HIS 对农场动物性能及其作用机制的影响。试图指出值得未来研究的知识差距。这些有益作用很可能与 HIS 诱导的肠道胰高血糖素样肽 2 分泌有关。最后,天然 HIS、新橙皮苷二氢查尔酮和甜菊糖苷具有促进猪和肉鸡肠道有益细菌生长的能力,有助于改善肠道健康。总体而言,当前的审查旨在概述 HIS 对农场动物性能及其作用机制的影响。试图指出值得未来研究的知识差距。本次审查旨在概述 HIS 对家畜生产性能的影响及其作用机制。试图指出值得未来研究的知识差距。本次审查旨在概述 HIS 对家畜生产性能的影响及其作用机制。试图指出值得未来研究的知识差距。
