Spray-dried plasma (SDP) is a functional ingredient commonly utilized in swine production and calf milk replacers to improve performance, feed efficiency, and health. The improvements noted with SDP in animal production are more pronounced under commercial production conditions compared to cleaner research settings. Multiple modes of action of SDP have been proposed, including either directly influencing the immune inflammatory response locally or systemically, and/or through the indirect modification of beneficial microbial populations. Spray-dried plasma included at various dietary levels and duration of feeding in broilers has been evaluated in different production and challenging conditions with beneficial effects on broiler performance, as noted in other animals. The purpose of this review is to discuss research related to the modes of action of SDP on immunomodulation and improved intestinal health and specifically discuss research conducted utilizing SDP in feed for poultry. Collectively, the data available indicates that SDP improves early intestinal health and supports an efficient immune system response both locally at the intestine and systemically, thereby benefiting growth, feed efficiency, and survival of broilers in conventional commercial production and under challenging conditions such as disease or environmental stressors.
喷雾干燥血浆（SDP）是一种功能性成分，常用于猪生产和犊牛代乳粉中，以提高生产性能、饲料效率和健康水平。与更清洁的研究环境相比，在商业生产条件下，SDP在动物生产中带来的改善更为显著。SDP的多种作用模式已被提出，包括直接局部或全身影响免疫炎症反应，和/或通过间接改变有益微生物种群。在肉鸡的不同生产和应激条件下，已评估了不同日粮水平和饲喂持续时间的喷雾干燥血浆，结果表明其对肉鸡生产性能有有益影响，这与其他动物的情况一致。本综述的目的是讨论与SDP免疫调节作用模式及改善肠道健康相关的研究，并特别讨论在家禽饲料中使用SDP的研究。总体而言，现有数据表明，SDP可改善早期肠道健康，并在肠道局部和全身支持有效的免疫系统反应，从而有利于传统商业生产中肉鸡的生长、饲料效率和存活，以及在疾病或环境应激等挑战性条件下的肉鸡生长、饲料效率和存活。
