2.1.2. Liquid formulationThis formulation consisted of a water emulsion based on 2.6%(w/v) B. carinata oil, containing 4.4 % (w/v) of B. nigra DSM,ground at 0.05 mm, with the addition of 6.9% (w/v) animal pro-tein hydrolysate, containing 9% N. The formulation was preparedaccording to the procedure described by De Nicola et al. (2013) andbased on a patent (Lazzeri et al., 2008). Differently from the DeNicola et al. (2013) procedure, B. nigra DSM was used instead of B.carinata DSM and the emulsion was not filtered before use.
