Definitions
- the invention is directed to a coated animal feed comprising active compounds.
- Animal feed is produced from different raw materials and additives in a feed factory.
- active compounds When active compounds are required in the feed, they are usually added in the main mixer of the production process. This has several disadvantages since many active compounds are sensitive to the high temperatures and other process conditions of the feed production process. More importantly, addition in the main mixer can lead to carry-over and cross contamination of the active compounds into next feed batches.
- carrier-over in this respect means that the active compound of a first production batch of animal feed contaminates the production facility and partially ends up in the next production batch of animal feed. Often carry-over leads to impurities in the final products. In particular, this is undesirable when the active compounds are additives like therapeutics, prophylactics, vitamins, enzymes, and other active compounds. To overcome these problems it has been suggested to add the active compounds after production, for example just before loading and transportation or even in a later phase, e.g. at the farm. It is very desirable to have the active compounds adhered to the animal feed in such a way that they remain evenly distributed and adhered during loading, transportation and delivery to the trough.
- EP-A-O 682 874 describes a bioactive feed pellet comprising a primary fat coating with a bioactive ingredient and a secondary fat coating which has been applied after the application of the primary coating.
- a suspending aid is used to provide dispersion and/or emulsion and/or solution properties of the bioactive compound.
- the suspension aid consists of a triglyceride and/or a fatty acid thereof having a melting point above 35 0 C.
- a disadvantage of the prior art fat coatings is that the amount of fat coating with respect to the feed pellet is relatively high. Normally, the coating content of the coated feed pellet is at least 2 wt.% with respect to the total weight of the coated feed pellet in order to effectively adhere the active compounds to the feed pellets. This high fat content is particularly disadvantageous for diseased animals.
- a further disadvantage of the prior art fat coated feed particles is the relatively bad adherence of the active compounds.
- the active compounds By the time that the animal feed has been loaded and transported to the farm, a large part of the active compounds has released from the feed pellets and is present in the dust. This can cause a problem for picky animals and, more importantly, may cause health problems for the farmer.
- An object of the present invention is therefore to provide an animal feed comprising active compounds, wherein the active compounds are adhered to the feed with a fat coating and wherein the coated feed has a low coating content.
- a further object is to provide a fat blend having improved crystallization behavior, in particular an increased crystallization rate.
- a coated animal feed which comprises at least one active compound and a coating for adhering the at least one active compound to the animal feed, wherein the coating comprises a blend of at least two lipid components, wherein at least one of the lipid components comprises a hardening lipid, and wherein the lower limit of the crystallization range of said blend is above room temperature.
- the lower limit of the crystallization range is above 35 °C.
- lipid refers to any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents and are oily to the touch.
- the hardening lipid can be a hydrogenated fat, a wax, or combinations thereof.
- Hydrogenated fat as referred to in this application is a hydrogenated fat wherein more than 75 % of the fatty acids are saturated. In a preferred embodiment of the invention the hydrogenated fat is a fully hydrogenated fat.
- the blend of lipid components preferably comprises from 1 wt.% to 50 wt.% of the hardening lipid, more preferably from 2 to 25 wt.%.
- the coating of the present invention increases the durability and abrasiveness of the feed.
- the animal feed of the invention is able to resist the abrasive forces and shearing forces that occur during transportation from the factory to the farm.
- the coating layer of the invention is hard and durable, but not brittle.
- the coating blend of lipid components of the present invention provides for the following benefits and advantages: 1. active particles are firmly captured on the feed particles;
- the feed particles have desired hardness and durability
- the crystallization rate of the blend is such that the coating solidifies rapidly, by which the active particles are captured before the feed particles collide with each other;
- the inventors surprisingly found that, in comparison to the prior art animal feed, less coating is required for adhering the active compounds to the feed when applying the hardening lipid in the blend of lipid components for the coating in accordance with the present invention.
- the blend of lipid components of the present invention preferably comprises from 1 wt.% to 50 wt.% of a hydrogenated fat and/or wax.
- a hydrogenated, preferably fully hydrogenated, fat obtained from rapeseed oil is a mixture of triglycerides in which the fatty acid composition is a mixture of saturated fatty acids. The fatty acids are present in the same proportions which result from the full hydrogenation of fatty acids occurring in natural rapeseed oil.
- the rapeseed oil is obtained from the napus and campestris varieties of Brassica of the family Cruciferae. It is prepared by fully hydrogenating refined and bleached rapeseed oil typically at 150 - 200 0 C, using a catalyst such as nickel, until the iodine number is about 4 or less.
- the lower crystallization point of the hydrogenated fat is preferably above 35 0 C, and more preferably above 50 0 C. From a practical point of view, a crystallization point of more than 65 0 C is not desirable.
- Suitable waxes for use in the blend of lipid components include, but are not limited to, carnauba, candilla, Japan and lanolin wax.
- the blend of lipid components further comprises a vegetable oil, such as soybean oil, palm oil, sunflower oil, palm kernel oil, palm oil fatty acids, corn oil, coconut oil, linseed oil.
- the blend of lipid components may also comprise an animal fat, such as fish oil, chicken fat, tallow, or lard.
- the crystallization range of the blend of lipid components may be adjusted by changing the ratio of the lipid components in the blend, for instance by changing the ratio of hydrogenated fat and/or wax with vegetable oil and/or animal fat.
- the lower limit of the crystallization range of the blend of lipid components should be above room temperature, preferably above 35 0 C.
- the blend of lipid components may solidify too fast by which it would become difficult to obtain a good coating.
- the crystallization range initiates at a temperature lower than 20 0 C, the blend of lipid components may not solidify at all, or solidify too slowly.
- the coating typically covers the feed particles in the feed according to the present invention more or less homogeneously.
- Typical coating thicknesses vary from 1 to 75 ⁇ m, e.g. from 2 to 30 ⁇ m. The inventors found that these thin coating thicknesses do not have a detrimental effect on the adherence of the active compound. This enables to use a relatively low amount of lipid coating with respect to the total weight of the coated animal feed, which is in particular advantageous for diseased animals.
- the weight ratio between vegetable oil and/or animal fat on the one hand and the hardening lipid on the other hand is typically from 99:1 to 10:90, depending on the crystallization range of the vegetable and/or animal fat. The weight ratio typically also depends on the initial composition, in particular the relative amounts of oil or fat therein. Generally, more hardening fat will have to be added to the blend to obtain a suitable lipid mixture with an oil than to obtain a suitable lipid mixture with a fat.
- the crystallization temperature of an oil is much lower than that of a fat
- the animal feed comprises between 0.5 wt.% and 2 wt.% of coating, more preferably between 0.7 wt.% and 1.0 wt.%.
- the at least one active compound may be any kind of active compound that is applicable to animal feed.
- the at least one active compound can be a therapeutic, a prophylactic, a vitamin, an enzyme, a yeast, and any other drug or additive that has a curing capacity or improves the performance of the animals, such as breeding performance, or milk production. Combinations of different kinds of active compounds are also included in the invention.
- the active compound may be a liquid or a solid. If the active compound is a solid, it is preferred that the solid is in the form of small particles with a size of from 1 ⁇ m to 2 000 ⁇ m, preferably from 50 ⁇ m to 200 ⁇ m.
- the amount of active compound per feed dosage may vary in a wide range.
- the invention also relates to a method for manufacturing an animal feed according to the invention comprising the steps of: providing an animal meal; producing animal feed of the meal (pellets, crumbles or meal) and distributing them to a mixing device; - optionally, finely distributing (e.g.
- a stickiness improving compound to the surface of the animal feed; mixing the at least one active compound with the animal feed; heating the blend of lipid components above the crystallization range of the blend; and - spraying the mix of at least one active compound with the blend of lipid components over the animal feed.
- the active compound is attached to the animal feed after the heating step, thereby preventing thermal degradation of the active compound.
- the stickiness improving compound can be applied to the surface of the uncoated animal feed to avoid excessive segregation of the animal feed and the active compound during mixing. Such segregation could occur in some mixing devices, in particular when there is a large difference in the respective sizes of the animal feed (typically made up of granules of 1 to several mm) and the active compound (typically a powder).
- the stickiness improving compound is generally a liquid, e.g. oil based, water based, carbohydrate based (e.g. dextroses, glucoses, starches, syrups, molasses or lignin), protein based (e.g.
- the coated animal feed of the present invention obtainable by the method comprising this optional step, thus typically comprises from 0.1 wt.% up to 2 wt.% (e.g. about 1 wt.%) of this stickiness improving compound.
- the animal feed is dosed in a mixer, together with at least one active compound.
- the blend of lipid components is heated above the crystallization range.
- the heating temperature is typically between 50 0 C and 95 0 C.
- the heated blend is sprayed over the animal feed.
- the coated animal feed may be actively cooled until below the crystallization range of the blend of lipid components. Alternatively, the feed may be left until the coating has hardened by itself.
- the hardening lipid in accordance with the present invention it is possible to accelerate the crystallization tremendously compared to a slow hardening coating.
- Another advantageous effect of the hardening lipid of the invention is that a lipid-gel is created.
- This lipid-gel is a very durable layer on the surface of the feed that is able to withstand the abrasive forces during transport.
- a lipid-gel is a mixture of liquid and solid lipids, wherein the high- melting lipid forms a solidified network, which encapsulates the liquid lower melting lipid. Lipid-gels results in increased structure, firmness and viscosity compared to the liquid lipid alone.
- the present inventors believe that the formation of a lipid-gel explains why in accordance with the present invention a relatively small amount of hardening lipid suffices to obtain a dramatic increase in mechanical hardness.
- the invention relates to the use of a hardening lipid with a crystallization point above 50 0 C, preferably above 65 0 C, as an adherent for at least one active compound on animal feed.
- Table 1 shows typical crystallization temperatures of pure lipids and lower limits of crystallization ranges of lipid blends comprising fully hydrogenated rapeseed oil (referred to as "FHR").
- the FHE crystallizes at a temperature of 69 0 C.
- Pure palm oil crystallizes at a temperature of 22 0 C.
- Figure 1 shows the effect of adding a fully hydrogenated fat (FHR) to palm oil on the hardness of the coating.
- FHR fully hydrogenated fat
- the numbers for each curve represent the weight percentage fully hydrogenated rapeseed oil of the total blend, 100 being pure fully hydrogenated rapeseed oil and 0 being pure palm oil. It can be seen that the addition of only 2 % fully hydrated fat has a large impact on the hardness (maximum force) of the blend. Measurements were carried out at 7 0 C using a Texture Analyzer (Stable Micro Systems). The lipids or lipid blends were first melted and allowed to solidify at room temperature. Then, the lipids/lipid blends were stored for one day at 7 0 C. One by one the samples were tested for their resistance to compression.
- the maximum force (maximum hardness) to deform the lipid was analyzed with the use of 10 mm probe at a test speed of 1 mm/s.
- the curves in Figure 1 have been recorded by monitoring the pressure that is exerted on the probe, while it travels at a constant speed of 1 mm/s through the sample. Typically, a peak in such a curve is associated with breakage. Thus the peaks observed in Figure 1, confirm that the blends of the present invention are in the form of a lipid-gel.
- FIG. 2 a schematic representation of coating layer 2 on top of feed 1 is given. Active compounds 3 are attached to the feed in accordance with the present invention by coating 2.
- Example 1 Fish feed pellets were coated with an active compound premix (an iron-particle tracer mixed with a carrier, at an inclusion level of 4 000 ppm) and were subjected to the Pfost test, a transport simulation test for measuring pellet durability, which involves measuring the level of dust and fines after a 500 times tumbling test (Pfost, Harry, Feed Production School Proceedings, KSU, 1962). Five hundred grams of pellets were weighed and put into the tumbling device. After the tumbling the fines and dust were screened off. The loss of weight was taken as representative for the fines and dust. The difference in weight before and after the simulation test is called the Pellet Durability Index. The recovery of the active compound was analyzed in the feed (not in the fines and dust particles). The results are given in Table 2.
- an active compound premix an iron-particle tracer mixed with a carrier, at an inclusion level of 4 000 ppm
- the recovery of the active compound was calculated by taking the analyzed level of tracer after the Pfost test and divide it by the initial addition level of the tracer in the coating step. Then this value was multiplied by 100 %. Due to inhomogeneity, segregation values of more than 100 % can occur. This happens with all analyses where the active components are stable during processing. The effects of adding different kinds of lipids is shown in Table 2.
- Premix amount of premix to be attached to the feed, 2 or 4 % of fat
- Fat amount of fat used to coat the feed 2 or 4 % fat
- Table 3 shows the recovery results in tests wherein the effect of adding different kinds of hardening lipids in the blend where investigated. All tests were done with a 2 % coating on total weight basis.
- the crystallization speed is doubled (see Table 5). If the lipid blend contains 5 wt.% of the fully hydrogenated fat or wax the crystallization speed is already three times higher. Several more crystallization rates were recorded as presented in Table 5. These data show the effect of adding the hardening lipid compared to an other lipid having a crystallization point lower than 55 0 C. Table 5
- Hard fatl Commercial hard frying fat; 100 % blend of palm oil fractions; 53 % saturated fats, 45 % unsaturated fat and 2 % trans fat.
- Hard fat2 Commercial hard frying fat; 100 % vegetable fat; 45 % saturated fats, 35 % mono-unsaturated fats, 15 % poly unsaturated fats, 5 % trans fats.
- the hardness of the animal feed lipid coating should be sufficient to resist abrasive forces during transport.
- Hardness measurements were carried out on lipid blends with a texture analyser (Stable Micro Systems) at 20 °C and 30 °C. The samples are stored in a stove of 20 or 30 0 C overnight to provide a homogeneous temperature in the sample. The maximum force (max hardness) to deform the lipid blend was analysed by using a 10 mm probe at downward travelling speed of 1 mm/s.
- Figure 3 shows the hardness of various lipid blends at 20 0 C as a function of the hard lipid content of the blend (FHR is fully hydrogenated fat; HR-DP is hydrogenated fat (> 75 % saturated fatty acids); Palm stearin is the hard fat fraction from palm oil).
- Figure 4 shows the hardness of various lipid blends at 30 0 C as a function of the hard lipid content of the blend.
- Figures 5 and 6 show individual hardness measurements carried out at 20 and 30 0 C, respectively. Differences in hardness of the lipid blend at these temperatures illustrate the beneficial effects of the specific hard lipids FHR, HR-DP and Carnauba wax, compared to palm stearin and pure palm oil.
