Abstract: Immune function of a plant can be modulated by administering a composition comprising beta glucan, where the beta glucan includes unbranched beta-(1,3)-glucan. Such unbranched beta-(1,3)-glucan can be obtained from Euglena, including heterotrophically grown Euglena. The unbranched beta-(1,3)-glucan can be in the form of paramylon and/or can be part of algae meal. The composition can further include a fertilizer, a pesticide, a fungicide, a bactericide, combinations thereof, as well as one or more various plant immune system modulators other than beta glucan. The wellbeing of the plant seed, seedling, mature plant, or harvested plant product can accordingly be improved.

Abstract: An animal feed composition includes algae meal and a feed component. The algae meal is present in an amount less than about 1000 g/MT by weight relative to a total weight of the animal feed composition. The animal feed composition may be administered to an animal for improving feed efficiency and increasing growth rate of the animal.
