Description

(54) FEED SUPPLEMENT FOR RUMINANTS (71) We, VOLAC lot., a British Body corporate of 7 Chelverton Road, Pfltney, London, S.W.15, do hereby declare the invention, for which we pray that a patent inay be granted to us, and the method by which it is to be performed, to be par ticularly described in and by the following statement: This invention relates to a feed supplement for ruminants, and to the production, composition, form and use of such a supplement.
It is desirable to add fats or lipids to the -diet of certain animals, such as cows and other ruminants, since diets of natural nutrient density tend to be so bulky that an animal's appetite is satisfied before it has received the full amount of nutrient which it is potentially capable of using to produce dairy products or meat. Bulk fat in the diet interferes with the rumination process and it is therefore desirable to provide the fat in a form which does not do so, for instance by mixing it with a non-fatty carrier material.
Known attempts to provide the fat in a suitable form have included coating the surfaces of known food pellets with fat by spraying or other means, but this technique has been found to be messy and wasteful, gives imprecise control over the level of fat in the finished product, and allows only relatively low quantities of fat to be added if a commercially. handleable product is to be produced. Another approach has been to soak carriers such as straw or vermiculite in fat in several stages, but although relatively high levels of fat can thus be incorporated in the carriers the carriers themselves have undesirably high bulk and substantially no nutritional value, and it has been found in practice that if more than 2 or 3% of fat in this form is incorporated into normal feed pellets, there is an undesirable tendency for the fat to be expressed during the pelletting process.
The present invention provides a feed supplement for ruminants consisting of dry particles each of which comprises a mixture of lipid material and de-lactosed whey (as hereinafter defined), the lipid content of the feet supplement being at least 40% by weight. Preferably, the particles will each consist of at least 40% by weight of lipid material with substantially all of the remain der being de-lactosed whey.
The requirement of young animals, before and after weaning, for diets containing total lipid levels of more than 5% by weight can be satisfied by pelletted feedstuffs containing the feed supplement according to the present invention.
De-lactosed whey is produced in large quantities as an aqueous waste product in production of lactose from whey and when dried is a hygroscopic substance which rapidly becomes sticky in air. It is an advan- tage of the feed supplement according to the present invention that it manufacture consumes this waste product while surprisingly providing a dry, non-sticky product which is convenient for commercial handling. It is a further advantage that the de-lactosed whey constitutes a carrier which is relatively high in nutritional value, and the proportion of lipid in the supplement may be of the order of 50 to 70% by weight, or even higher, without the lipid apparently being expressed during normal production of pelletted feedstuffs containing the supplement. The feed supplement according to this invention tends to pass relatively quickly through the rumen of a cow or other ruminant, thus reducing the likelihood of interference with the rumination process, and possibly reducing any degradation of the lipid, such as may occur by hydrogenation in the rumen if polyunsaturated lipids are used.
The term "de-lactosed whey", as used herein, is to be understood as including any product formed by extraction of lactose from whey, in which the residual lactose constitutes less than 65% by weight of the dry solids, dried whey itself containing at least 65% lactose. Preferably, the de-lactosed whey to be used in the feed supplement according to the present invention contains 38.5% .by weight of lactose and 25% by weight of protein, both based on the total dry solids, the remainder being mineral salts, fat and moisture.
Suitable lipids for use in the feed supplement according to the invention include for example solid fats such as beef tallow, hog fat, coconut oil, palm oil and palm kernel oil and liquid (at ambient temperatures) fats and oils such as soya oil, cottonseed oil, linseed oil or corn oil or combinations of these oils.
The lipid and the de-lactosed whey may be combined by any convenient method which produces an acceptable product, a preferred method involving spray drying of an aqueous emulsion containing suitable relative proportions of the lipid and delactosed whey, preferably within the range from 40 to 70% by weight of lipid and 30 to 60% of delactosed whey, based on total emulsion solids. The emulsion preferably includes an emulsifying agent, for example a mixture of glyceryl mono-stearate and soya lecithin, a suitable quantity thereof being 1% to 2% by weight based on the total weight of lipid plus emulsifying agent. The emulsion may be prepared by mixing the emulsifying agent in the melted fat and further mixing with concentrated de-lactosed whey or with a dispersion in water of dry de-lactosed whey. The liquid mixture produced in either of these ways may be homogenised by conventional means to reduce the lipid to particles of a suitable size in the emulsion, a maximum lipid particle diameter of 8 s1 being preferred.
The spray drying of this emulsion to produce the desired feed supplement may be effected in conventional spray drying equipment, e.g. by spraying the emulsion into a hot air stream. Suitable equipment is described in "Spray Drying" by K. Masters, published by Leonard Hill Books, London.
The emulsion, preferably containing 45% to 65% solids, may be fed to the jet spray drier at pressures within the range from 1000 psi to 2500 psi and the drying temperature is preferably within the range from 75 to 1000C outlet air temperature.
Embodiments of the invention will now be described in greater detail in the following specific Examples.
EXAMPLE I 263 kilos of de-lactosed whey which has been concentrated to 38% total solids, are added to a melted premix of 99 kilos beef tallow, 0.2 kilos of glyceryl monostearate, and 0.8 kilos of soya lecithin and further mixed with continuous agitation and heated to 650C and held at that temperature for 10 minutes to pasteurise the mixture. The mixture is then fed to an homogeniser using pressure of 1500 psi, and the resulting emulsion is pumped to the spray jet at a pressure of 1000 psi into a hot air stream temperature 1800C and is thus dried. The dried powder is recovered, cooled, and sieved. 200 kilos of the powder are blended with 1550 kilos of conventional cattle meal using a ribbon type powder blender and the final product is fed to a pelletting machine to produce discrete firm non-oily pellets with minimum crumbling.
EXAMPLE 2 100 Kilos of spray dried de-lactosed whey is dispersed in 200 litres water at a temperture of 1500C and to this is added a melted mixture of 99 kilos tallow, 0.2 glycerol monostearate and 0.8 kilos soya lecithin.
The final mixture is heated to 650C with continuous agitation and held at that temperature for ten minutes to pasteurise. This mixture is then processed in accordance with Example 1.
EXAMPLE 3 The process as explained in Example 1 is followed except that the homogenised mixture is fed to a spinning disc type of spray drier using an inlet temperature of 165"C and an outlet temperature of 800C.
EXAMPLE 4 The process as described in Example 3 is followed except that 150 kilos of spray dried de-lactosed whey dispersed in 250 litres of water are used. A similar product is obtained but containing only about 40% by weight of lipid.
EXAMPLE 5 263 kilos of de-lactosed whey which has been concentrated to 35% total solids are added to a melted premix of 233 kilos beef tallow, 0.46 kilos soya lecithin and further and 1.87 kilos soya lecithin and further mixed with continuous agitation and heated to 650C and held at that temperature for 10 minutes to pasteurise the mixture. The mixture is then fed to an homogeniser using a pressure of 1500 psi and the resulting emulsion is pumped to a jet two fluid spray jet where the liquid pressure is 500 psi and the air pressure is 700 psi. The fluid/air jet is sprayed into a hot air stream at a temperature of 1800c and is thus dried. The dried powder is thereafter treated as in Example 1.
EXAMPLE 6 The process as described in Example 2 is followed except that the beef tallow is replaced by soya bean oil.
