NO DRAWINGS PATENTS ACT 1953 COMPLETE SPECIFICATION ANIMAL FEED WE INTERNATIONAL ANIMAL HEALTH PRODUCTS PTY. LTD a company incorporated under the laws of the State of New South Wales, Australia of 6 Dupas Street, Smithfield, New South Wales, 2164, Australia hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed to be particularly described in and by the following statement: 248001 This invention relates to a livestock feed having improved anti-static and dust control properties.

Livestock feeds are frequently combined with anti-bacterial agents and the like prior to use.

However, there is a considerable danger of flammability and explosion during mixing. Furthermore, due to the inherent granulometric characteristics of the anti-bacterial agents, the resulting livestock feed generally gives rise to undesirable high levels of dust. 10 Most of the conventional livestock feeds used in industry tend to crumble when pulverized and this can lead to dust inhalation by process workers. Some of the additives contain selenium based or other compounds which cause respiratory disorders and other illnesses in humans. The 15 high levels of dust in feed also results in the inevitable loss of valuable livestock feed in windy areas. In addition, livestock feeds of this type result in uneven and unhomogeneous blending of active materials resulting in over-dosing in some animals and under-dosing 20 in others. It has been proposed to incorporate calcium supplements in livestock feed, for example, horse feed. However, the problems of dust are in that case exacerbated.

In order to overcome these problems, conventional feed products are manufactured in pellet form. However, pelleting limits vitamin and mineral content, especially calcium to unacceotablv low levels.

ZD v' / \ ."V-- 594 248001 It is an object of the present invention to provide a livestock feed which avoids or at least ameliorates some of the above discussed disadvantages of the prior art.

In a preferred embodiment, the present invention provides a livestock feed composition which is a substantially austless calcium containing feed having improved anti-static properties.

According to one aspect, the invention consists in 10 a substantially dustless livestock feed composition comprising: (1) a carrier feed (2) a calcium salt or mixture of calcium salts in a total amount up to 97% by weight of the total composition and (3) an amount of up to 2% by weight of the total composition of a non-ionic solubilizsr, emulsifier or surfactant selected from the group consisting of mono-esters derived from reaction of propylene glycol 2 0 with an alimentary fatty acid; esters derived from reaction of a mono- or di-glyceriae with an alimentary fatty acid; esters derived from reaction of a mono- or di-glyceride with acetic, lactic, citric, tartaric, or monoacetyltartaric acid; glycerol-polyethylene glycol 25 ricinoleate,• esters derived from reaction of polyethylene glycol with soybean oil fatty acid; sorbitan monostearate; sorbitan tristearate,- sorbitan monolaurate; sorbitan'mono-oleate; sorbitan monopalmitate; 24800 polyoxyethylated castor oil; propylene glycol alginate, glycols, and combinations thereof.

According to a second aspect, the invention consists in a dustless concentrate for combination with a 5 livestock carrier feed to provide a dustless livestock feed composition according to the first aspect; said concentrate comprising-. (1) a calcium salt or mixture thereof and (2) an amount of up to 2% by weight of the concentrate 10 of a non-ionic solubilizer, emulsifier or surfactant selected from the group consisting of mono-esters derived from reaction of propylene glycol with an alimentary fatty acid; esters derived from reaction of a mono- or di-glyceride with an alimentary fatty acid; esters 15 derived from reaction of a mono- or di-glyceride with acetic, lactic, citric, tartaric, or monoacetyltartaric acid; glycerol-polyethylene glycol ricinoleate; esters derived from polyethylene glycol with soybean oil fatty acid; sorbitan monostearate,- sorbitan tristearate; 20 sorbitan monolaurate; sorbitan mono-oleate; sorbitar. monopalmitate and propylene glycol alginate, glycols ana combinations thereof.

Compositions according to the invention typically include a meal or flour foodstuff in a proportion which 2 5 depends upon the foodstuff and the type and number cf animals to be fed.

In one preferred embodiment of the present "V ✓ invention, the composition or concentrate further 24800 comprises a vitamin and/or mineral or combination of vitamins and/or minerals in a total amount up to 0.1% and more preferably in the range of from 0.01% to 0.09% by weight of the total feed product. Although any vitamin 5 or mineral can be used in the livestock feed, a combination of vitamin A and vitamin D in a ratio of 3 :1 is preferred. The vitamin and mineral component can be altered and different blends can be used depending on the intended use.

The composition or concentrate may also comprise skim milk powder in an amount of up to 10% and more preferably up to 5% by weight of the total feed product.

Desirably, vanilla powder is added to the feed for improved flavour in an amount of up to 0.07% and more 15 preferably up to 0.05% by weight of the feed product.

The feed composition or concentrate may further comprise of one or more additives such as those selected from the group consisting of antibacterial, antibiotic, anthelmintic, antifungal, anticoccidial, antiseptic, 20 probiotic, enzyme or a combination thereof.

Highly preferred embodiments of the invention comprise one or more additives selected from the group consisting to antibacterial, antibiotic, anthelmintic, antifungal, anticoccidial, antiseptic, probiotic, enzyme, 25 or a combination thereof whose granulometric characteristic is 80 mesh for at least 90% by weight of the additive, said additive being present in an amount of between 0.001% and 90% by weight of the feed. 2480 Calcium gluconate and calcium carbonate are the preferred calcium salts used in the present invention. .In a preferred embodiment, the composition or concentrate comprises calcium gluconate in an amount of up to 7% and 5 more preferably up to 5% by weight of the feed product and calcium carbonate in an amount of up to 90% by weight of the feed product. The total composition of calcium salts is desirably present in an amount up to 97% by weight of the feed product. The composition can be in 10 powder form and maintains a high calcium level with reduced dust and improved anti-static properties. A further advantage is that the composition reduces adhesion to containers or mixers and consequently reduces the potential for wastage or contamination of succeeding 15 batches.

It has been found that the addition of the emulsifier reduces the static and thus explosion hazard as well as greatly simplifies the efficient mixing of the additive with the feed product while not detracting from 2 0 its value as a feed.

Desirably, an emulsifier is used in the present invention in an amount of up to 1.5% by weight of the total feed product. Polvoxyethylarec castor oil is "he preferred emulsifier.

The livestock composition further comprises a carrier feed or feed flour. Desirably, a glycol, for example propylene glycol, glycerol or polyethylene glycol is added to the feed carriers. % 24800 The application of this livestock feed composition has been found to improve the uniformity of the blend composition to provide a vitamin and mineral enriched free flowing, dustless meal with desirable handling 5 properties.

Embodiments of the present invention will now be described by way of examples only.
