Characteristics of Microalgae and Its Application in Ruminant Production
Microalgae is abundant in species and rich in a variety of nutrients,possessing biological activities such as anti-inflammatory and anti-oxidation.In livestock production,microalgae can be used as feed ingredi-ents to alleviate the demand for grains such as corn and soybean.Particularly,microalgae is high in n-3 fatty acids,which can improve the fatty acid profile of livestock products and enhance their nutritional value,benefi-ting ruminant animals and human health.However,there are still limitations to the use of microalgae as feed,such as high cost,safety risk,different digestibility and optimal addition amounts of different microalgae,which make it challenging to establish standardized technological application models.This article provided an o-verview of the nutritional characteristics and biological activities of microalgae,as well as its application in ru-minant production,aiming to provide reference for the use of microalgae in ruminant production.[Chinese Journal of Animal Nutrition,2024,36(12):7563-7572]
