Feedstuffs for domesticated animals can be improved by inclusion of choline e.g. as choline chloride. Ruminants cannot benefit from choline in feed unless the choline is protected from destruction in the rumen. Improved protection against ruminal destruction is provided by supporting the choline compound, especially as an aqueous solution, on a carrier particularly ground corn cob, other similar cellulosic material, or porous hydrophilic silica, and coated with or included within a matrix of a protective fatty acid or soap having a melting point above 40 °C. Even better results can be obtained by including alkali with the choline compound to form caps of soap over the choline compound in the pores of the carrier and/or to plasticise the fatty acid matrix. |
