Analysis of the Impact of Isoquinoline Alkaloids, Derived fromMacleaya cordataExtract, on the Development and Innate Immune Response in Swine and Poultry

Abstract

Medicinal extract has been chronicled extensively in traditional Chinese medicine. Isoquinoline alkaloids, extract ofMacleaya cordata(Willd.) R. Br., have been used as feed additive in both swine and poultry. Dietary supplementation with isoquinoline alkaloids increases feed intake and weight gain. In addition, recent researches have demonstrated that isoquinoline alkaloids can regulate metabolic processes, innate immune system, and digestive functioning in animals. This review summarizes the latest scientific researches on isoquinoline alkaloids which are extracted fromMacleaya cordata(Willd.) R. Br. This review specifically focuses on its role as a feed supplement and its associated impact on growth performance and innate immune system, as well as its capacity to act as a substitute for oral antibiotics.
