In vitro dry matter digestibility of multiple sources of microalgae and microalgae products for growing pigs

An abstract of a study by Hanson et al measuring the nutrient composition and in vitro dry matter digestibility (IVDMD) of different microalgae sources is presented. The IVDMD of Pavlova sp. (50.7 ± 0.5%) was less (P < 0.05) than that of Chlorella sp. grown in dairy waste water (57.1 ± 0.1%), which was greater than that of Chlorella sp. grown in meat processing waste water (64.2 ± 0.9%). The greatest IVDMD was observed in the protein and lipid extracted microalgae product (80.2 ± 4.9%). Digestibility values of microalga grown in dairy waste water and grown in meat processing waste water were not different (P > 0.05) from ground corn (62.6 ± 2.7%) used as control.
