Abstract: A stable liquid ingredient composition for liquid animal feed, which is stable from 0 to about 40° C. and also forms a stable dispersion in water. The composition includes oleyl lactylate and salts thereof (OL), and a further lactylate selected from lauroyl lactylate and salts thereof (LL), or a mixture of lauroyl lactylate and myristoyl lactylate and/or their salts (LL/ML blend). The weight ratio of the lactylate selected from LL or the LL/ML blend to OL in the stable liquid ingredient composition ranges from 1/99 to 60/40. The stable liquid ingredient composition may optionally include a diluent. The composition provides an alternative to solid feed ingredients or additives and can be applied as ingredient in liquid feed for animals such as in drinking water. Use of the stable liquid ingredient composition allows a reduction in the use of antibiotics and helps to maintain a good health of the animal.
