Abstract
Abstract A nonagglomerating, nonsegregating premix for animal feeds comprising an intimate mixture of an active ingredient and a carrier. The active ingredient has dispersed upon the particles thereof a quantity of a first emulsifier equivalent to 0.1 to 1.0 percent by weight of the active ingredient, the emulsifier having an HLB value of at least 12. The carrier has dispersed upon the particles thereof a quantity of a second emulsifier equivalent to 0.1 to 1.0 percent by weight of the carrier and having an HLB value of 8 or less. The ratio of active ingredient to carrier in the premix can vary from 1 to 9 parts by weight to 4 to 1 parts by weight. Such premixes when blended with feed produce little if any electrostatic charge.

Claim 11
Independent Claim
191 words
A method for preparing an animal feed premix comprising the steps of admixing an additive selected from the group consisting of arsanilic acid, 3-nitro-4-hydroxyphenylarsonic acid, menadione, nicotinic acid, sulfaquinoxaline and the nitrofurazones having a particle size in the range of 60- 325 mesh and having a coating thereon of a high HLB emulsifier equal in weight to 0.1 to 1.0 percent of the weight of the additive and having an HLB value greater than or equal to 12; admixing a carrier selected from the group consisting of ground oats, rye, wheat, and barley; soy flour; corn germ cake; corn germ meal; soybean oil meal; corn gluten feed; corn meal; corn cob fractions; dolomite, calcite; and limestone having a particle size in the range of 20- 325 mesh and having a coating thereon of mesh a quantity of a low HLB emulsifier equal in weight from 0.1 to 1.0 percent of the weight of the carrier and having an HLB value equal to or less than 8; combining said carrier and said additive in ratios of from 1 part additive to 9 parts carrier to 4 parts additive to 1 part carrier.
Claim 12
Dependent Claim
42 words
A method according to claim 12 wherein said high HLB emulsifier is first dissolved in sufficient water or water combined with water miscible solvent to form a slurry; said slurry being subsequently dried prior to combining the treated additive with the carrier.
