FODDER ADDITIVE FOR CATTLE IN FORM OF ENCAPSULATED FATS AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2020 - IPC A23K10/00 

FIELD: feed industry.

SUBSTANCE: method of producing a fodder additive for cattle in the form of encapsulated fats, involving formation of an alginate emulsion and an active substance, encapsulation by contacting emulsion drops with an aqueous solution of divalent metal ions. For formation of emulsion as an active substance, soya fractionated lecithin is used, as encapsulating mixture there are used sodium and/or potassium salts of alginic acid in any ratio, wherein soya lecithin heated to temperature of 70–75 °C is mixed with encapsulating mixture at ratio of 6–8:4–2 respectively, mixed until homogeneous mass by means of magnetic mixer for 10–20 minutes and through spinnerets into 5–20 wt% Ca2+ salts solution, adjusting the volume of the dropping drop of the encapsulated mixture to obtain microcapsules with a diameter of not more than 5 mm, obtained microcapsules are washed with distilled water, decanted and dried for 3–5 hours at 85–95 °C, periodically stirring 3 times an hour. Fodder additive for cattle in form of encapsulated fat obtained by the method described above and representing microcapsules with diameter of not more than 5 mm, in which the alginate is the coating, specifically sodium and/or potassium salts of alginic acid in any ratio, and as a core – fractionated soya lecithin.

EFFECT: invention allows to produce a fodder product that will compensate for energy balance in animals, as well as increase fat content of milk yield when using in period of calving and lactation by excreting about 97 % of phospholipids of encapsulated mixture only in medium of small intestine, which provides reduced negative effect on digestion of cattle, as well as high digestibility and bioavailability.
