Name of Applicant: e Actual Inventor: Address for Service: INTERNATIONAL ANIMAL HEALTH PRODUCTS PTY LTD, A.C.N. 003 185 699 CHRISTOPHER JOHN LAWLOR SHELSTON WATERS Clarence Street SYDNEY NSW 2000 "ANIMAL FEED" Invention Title: 4 Details of Associated Provisional Application Nos.

PL3252 dated 29/6/92 and PL3474 dated 10/7/92 The following statement is a full description of this invention, including the best method of performing it known co me/us:- 1. e. e 2 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.

Most of the conventional livestock feeds used in indtstry 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 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 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 unacceptably low levels.

I b.- -3j r r k S r 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 dustless calcium containing feed having improved anti-static properties.

According to one aspect, the invention consists in a substantially dustless livestock feed composition comprising: a carrier feed; a calcium salt or mixture of calcium salts in a total amount up to 97% by weight of 10 the total composition; and an amount of up to 2% by weight of the total composition of a polyoxyethylated castor oil as an emulsifier.

According to a second aspect, the invention consists in a concentrate for combination with a livestock carrier feed to provide a dustless livestock feed 15 composition according to the first aspect, said concentrate comprising: a calcium salt or a mixture thereof; and up to 2% by weight of the concentrate of a polyoxyethylated castor oil as a emulsifier.

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

In one preferred embodiment of the present invention, the composition or concentrate further comprises a vitamin and/or mineral or combination of vitamins

I

17011.0,flOClckjc -4and/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 or mineral can be used in the livestock feed, a combination of vitamin A and vitamin D 3 in a ratio of 5:1 is preferred. The vitamin and mineral component can by altered and different blends can by used depending on the intended use.

The composition or concentrate may also comprise skim milk powder in an amount of up to 7% 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 preferably up to 0.05% by weight of the feed product.

S 10 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, probiotic, enzyme or a combination thereof.

e Highly preferred embodiments of the invention comprise one or more additives selected from the group consisting of antibacterial, antibiotic, anthelmintic, antifungal, anticoccidial, antiseptic, probiotic, enzyme, 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.

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 more preferably up to 5% by weight of the feed product and calcium carbonate in an amount of up to 90% by weight RA of the feed product. The total composition of calcium salts is desirably present in an 7 0 D 01 i i i.oo.DoOC/kJc amount up to 97% by weight of the feed product. The composition can be in 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 contmination of succeeding 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 its value as a feed.

Desirably, the emulsifier is used in the present invention in an amount of up to 1.5% by weight of the total feed product.

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 0.

0 4 :L:o 17011 0.0DOCAlc 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 properties.

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

In one embodiment of the invention, a meal or flour is first loaded into a blender of the type normally employed for the blending of powder-like substances.

Suitable meals would be protinic meals, cereal meals, flours, bran, yeast protein, oil-seed extraction residues and the like. The flours may be ground so that at least i 80% by weight is less than 80 mesh. The meal is then combined with the concentrate from Example 1, 2 or 3.

The components of Example 1 is especially suitable ii as feed supplement for horses while composition of Example 2 is especially suitable for pigs.

The concentrate of example 2 is mixed with feed at the following rates:- For pigs less than 35 Kgs. body weight the concentrate is added to the feed meal at 100 ppm. For pigs over 35 Kgs. body weight (50 ppm).

For horses the following amounts of the concentrate of example 1 are mixed in wet or dry feed.

Concentrate Horses in Work 60 to 90 g per day Spelling Horses 30 g per day Lactating Horses 60 to 90 g per day Dry Mares 30 g per day Yearlings 60 g per day i Weanlings 30 g per day The application of the composition to the food has been found to provide a free flowing, dustless food with 20 desirable handling properties.

As will be apparent to those skilled in the art from the teaching hereof, other anti-fungal, anti-biotic, anthelmintic and the like additives can be incorporated with the feed, using concentrate in accordance with the invention.
