Abstract: The present invention relates to a process for preparing cores of granules intended for animal nutrition, the said cores comprising: a hydrophilic active principle present in an active content of greater than or equal to 60% by weight, at least one meltable binder, at least one plasticizer, the said process comprising (a) a first step of mixing of the ingredients, (b) a second step of extrusion of the mixture through an extruder, especially a single-screw or twin-screw extruder, equipped with one or more dies, so as to obtain rods, and (c) a third step of spheronization of the rods, the said process being characterized in that a preliminary dry co-grinding of the ingredients is performed before extruding the mixture, the said co-grinding being performed at a temperature of not more than 50° C. The present invention also relates to a process for preparing granules of hydrophilic active principle comprising the said cores.

Abstract: A particulate composition comprising (a) an oil of a vitamin, an oil containing one or more vitamins or a derivative, (b) a gelling agent of vegetable origin having a glass transition point greater than 20° C., and (c) a protein, except gelatine.

Abstract: The present invention relates to cores of granules of hydrophilic active principle, characterized in that they also comprise starch or a derivative thereof. The present invention also relates to hydrophilic active principle granules intended for the nutrition or treatment of ruminants.

Abstract: The homogeneous solid granules of the invention comprise at least 5% (w/w) of carotenoid, gelatine and a sugar, they have a size distribution of from 100 ?m to 2000 gm and are solvent-free. The process for producing such granules comprises the following steps: (a) preparing an aqueous solution of at least gelatine and a sugar, (b) adding at least said carotenoid in said aqueous solution, (c) adding the preparation obtained in (b) to an oil to obtain an emulsion of granules, (d) cooling said emulsion to solidify the granules, and (e) recovering and drying the granules.

Abstract: A process for the preparation of granules of methionine which process comprises (a) forming a mixture of methionine powder, a binding agent and water (b) applying the mixture to high shear rate mixing, thereby forming granules of said mixture; and (c) drying said granules. Granules produced by the aforementioned process characterised by a bulk density of at least 0.6 g/cm3, and a particle siye distribution of from 50 to 2000 microns are also claimed as well as an animal feed composition comprising the granules.

Abstract: An animal rumen-resistant feed supplement in the solid form, said feed supplement comprising at least one methionine derivative and a porous carrier material wherein (a) said methionine derivative is selected from the group consisting of liquid and solid esters of the 2-hydroxy-4-(methylthio)butanoic acid, with the proviso that solid esters have a melting point of 100° C. at most; the 2-amino-4-methylthiobutanamide and the 2-hydroxy-4-methylthiobutanamide, (b) said methionine derivative accounts for at least 20% and up to 70% by weight of the feed supplement and (c) said supplement is in the form of particles having a size range of from 80 to 600 microns.
