Milk containing animal feed compositions, and aqueous feeds containing them, are stabilised by the presence of a complex salt consisting of ammonium, alkali metal or alkaline earth metal ions and formic acid in which the ratio of acid to ions is from 2:1 to 4:1. Preferred complex salts are those commonly known as ammonium tetraformate and potassium diformate. The milk containing compositions can contain 0.10 to 5, preferably 0.5 to 2% wt. of complex salts, corresponding figures for the aqueous feeds being 0.01 to 0.5, preferably 0.05 to 0.2% wt. The complex salts can be added as solids, when appropriate, or as an aqueous solution or distributed on a comminuted solid carrier (e.g. finely divided silica). |
