Description
METHOD AND FEEDSTUFF FOR THE PRODUCTION OF EGGS FIELD OF THE INVENTION
The present invention relates to a method and feedstuffs for the production of eggs from poultry and more particularly to a method and feedstuff which will produce eggs having an enhanced Omega-3 fatty acid content. BACKGROUND ART
There has been considerable scientific interest in the Omega-3 long chain polyunsaturated fatty acids (n-3 PUFA) in human health. The n-3 PUFA are fatty acids having one of their double bonds three carbons in from the terminal methyl group in the chain. The most common of the n-3 PUFA are alpha-linolenic acid (ALA, 18:3, n-3), eicosopentaenoic acid (EPA, 20:5, n-3) and docosohexaenoic acid (DHA, 22:6, n-3). A few vegetable oils such as linseed, rapeseed (canola) and soybean contain ALA while fish are the primary source of EPA and DHA.
It has been recognised for some time that there is excess fat in the diet of many humans, particularly in the western world. It has more recently been recognised that not only do we consume too much fat but the type of fat we consume is incorrectly balanced. It has been found, for instance, that those who consume significant amounts of fish on a regular basis, throughout their life, generally have a reduced incidence of death from heart disease. Until recently nutritionists thought that certain polyunsaturated fatty acids particularly linoleic acid (an omega-6 long chain polyunsaturated fatty acid) were of central importance in our diet. Manufacturers therefore concentrated on providing foods such as cooking oils, margarines, mayonnaise and soft spreads that were high in linoleic acid. It has now been realised that this approach totally overlooked the role of the omega-3 PUFA and that, in fact, the question is not which of these two "families" of PUFA is most important, but rather what is
the optimum ratio of omega-6 PUFA to omega-3 PUFA in our diet. In a typical "western" diet the ratio of omega-6 to omega-3 may be 25 or 30:1; the ideal ratio is less than 10:1. It has also been known that the fatty acid profile of the eggs of poultry may be altered by feeding to the female birds a diet high in a particular type of fatty acid including the omega-3 PUFA. The present inventors and others have previously produced eggs having an enhanced omega-3 PUFA however there have been a number of problems with the production of such eggs from the feedstuffs so far utilised for this purpose. The eggs have been inconsistent as to their actual omega-3 PUFA content; there have been common incidences of the development of off-flavours in the eggs; the storage qualities of the eggs have been, in some cases, questionable; and the ratio of omega-6 PUFA:omega-3 PUFA has been highly variable.
The present invention is directed to a feedstuff and a method for the production of omega-3 PUFA enhanced eggs which ameliorates at least some, and in preferred cases all, of the deficiencies of known omega-3 PUFA enhanced eggs. DISCLOSURE OF THE PRESENT INVENTION In a first aspect the present invention consists in a feedstuff for laying poultry suitable to induce poultry consuming the feedstuff to produce eggs having an increased omega-3 polyunsaturated fatty acid (PUFA) content, the feedstuff containing (a) from 1.5% to 2.5% by weight of a fish oil, or oils, having at least 20% by weight of its, or their combined, fatty acids content in the form of omega-3 polyunsaturated acids, (b) from 1% to 4% by weight of linseed oil, (c) an effective amount of at least one feed acceptable
antioxidant, and
(d) the balance of the feedstuff being a suitable commercial laying ration containing insignificant amounts of polyunsaturated fatty acids, at least 25% of the total omega-3 polyunsaturated fatty acids present in the feedstuff being in a form other than alpha linolenic acid and the feedstuff having a total polyunsaturated fatty acid content of no more than 5.5% by weight. In another aspect the present invention consists in a feed supplement for addition to a suitable commercial laying ration containing no more than small amounts of polyunsaturated fatty acids, the feed supplement containing
(a) from 20% to 55% by weight of a fish oil, or oils, having at least 20% by weight of its, or their combined, fatty acids content in the form of omega-3 polyunsaturated acids,
(b) from 20% to 55% by weight of linseed oil, and
(c) an effective amount of at least one feed acceptable antioxidant.
In a third aspect the present invention consists in a method for the production of eggs having an enhanced omega-3 polyunsaturated fatty acid content comprising feeding to laying poultry a feedstuff according to the present invention.
The fish oil preferably will have an omega-3 PUFA content of at least 25% by weight and most preferably 30% by weight. A suitable oil such as mackerel oil is commercially available, however, other suitable fish oils may be used with equal effect.
These oils will typically have a low alpha linolenic acid content and a very low ratio of omega-6 PUFA: omega-3 PUFA (< 0.5) . The linseed oil is preferably introduced as a pure oil however it is possible to introduce this oil in the form of flax seeds. The ratio of the fish oil and
the linseed oil must be adjusted according to their respective fatty acid profile, however, ratios of 55% to 45% by weight of fish oil or oils to 45% to 55% by weight of linseed oil are preferred. The fish oil and the linseed oil can be incorporated into the feedstuff or the feed additive as a dry powder having been adsorbed onto a particulate carrier such as milled lucerne meal. This greatly facilitates the mixing of the feedstuff to ensure a uniform distribution of the oils through the feedstuff or feed supplement. In the case of a dry powder, it has been found that a ratio of 40% to 60%, more preferably 45% to 55%, by weight of oil to 60% to 40%, more preferably 55% to 45%, by weight of particulate carrier is acceptable. A most preferred ratio of oils to carrier is to have them present in equal proportions plus or minus 1% by weight.
The fish oil and linseed oil can also be incorporated into the feedstuff as a liquid. The liquid can be shipped to egg producers who mix the liquid with an appropriate quantity of laying ration.
The antioxidant or antioxidants are preferably so selected, and are present in sufficient amounts, to preserve the oils from developing rancidity in the feedstuff or the feed supplement and in addition in-vivo in the bird and in-ovo in the egg. The preferred antioxidant to preserve the oils in the feedstuff or supplement is ethoxyquin while that to preserve the oils in-vivo and in-ovo is vitamin E. The combined antioxidants are preferably present in an amount of 1% by weight of the feed supplement or less. In the case of the particularly preferred antioxidants their combined weight need only amount to .0005% by weight of the feedstuff. The feedstuff according to the present invention should be fed to the birds in a normal amount according to their energy requirements. This will vary with
environmental factors from about 90g/day in hot weather to 140g/day in cold conditions. The oil intake of the birds is desirably maintained substantially constant despite variations in energy requirements so that the proportion of the oils in the diet may need to be varied to allow for this.
The total fat in the feedstuff will preferably contribute less than 6% of a laying hen's diet.
It has been found that preferred embodiments of the method according to this invention have yielded highly reproducible results. The eggs produced have all had inexcess of 400mg of omega-3 PUFA in a 55g egg. The ratio of omega-6 PUFA - omega-3 PUFA is below 5:1 and is commonly as low as 1.5:1. Eggs produced by the method according to the present invention have a well balanced nutritional profile and are suitable to be consumed as a substantial part of the diet. In addition to their suitability for inclusion in the adult diet they are also particularly useful as a means of introducing omega-3 PUFA into infant formulae which are noticeably lacking in these fatty acids notwithstanding their presence in mothers milk and their essential role in human development.
