Description
FEED COMPOSITION FOR A BROILER
This invention relates to a feed composition for a broiler in order to produce chicken rich in n-3 fatty acid, wherein an n-3 fatty acid is an ethylenically unsaturated fatty acid in which the first double bond of the unsaturated fatty acid is located at the third carbon atom from that end of the carbon chain remote from the carboxcylic acid group.
A chicken which is rich in n-3 fatty acid is beneficial to humans and further can prevent various physiological disorders caused by chicken having a high n-6 fatty acid content, wherein an n-6 fatty acid is an ethylenically unsaturated fatty acid in which the first double bond of the unsaturated fatty acid is located at the sixth carbon atom from that end of the carbon chain remote from the carboxylic acid group. The invention also provides a method for producing chicken rich in n3 fatty acid, which comprises supplying to a broiler the inventive feed composition, and chicken rich in n-3 fatty acid produced by such a method.
In chicken presently on the market, the content of n-3 fatty acid is very low, for instance around 1 & and the content of n-6 fatty acid is high, for instance about 14 to 20%, of the total fatty acids.
Accordingly, as such chicken may cause various physiological adverse effects due to n-6 fatty acid, particularly high arachidonic acid, and furthermore contains a high level of cholesterol, there is a tendency to avoid the intake of chicken.
Linoleic acid, as an n-6 fatty acid which is contained in chicken in large quantities, is metabolized to arachidonic acid which is then further metabolized to various eicosanoids, i.e. 2-series prostaglandins and 4-series leukotrienes, in the cell membrane of the body tissue. It has been disclosed that excessive eicosanoids produced due to the excessive intake of n-6 fatty acid may cause various physiological disorders such as atherosclerosis, hypertension, myocardial infarction, ischemia, thrombosis, heart disease, osteomyelitis, and skin disease. Accordingly, it has been required to decrease the n-6 fatty acid content and to increase the n-3 fatty acid content in chicken.
In the prior art, in order to produce chicken rich in n-3 fatty acid it has been suggested that the feed composition could contain rape seed as a n-3 fatty acid source. However, it has been disclosed that, when using rape seed as a source of n-3 fatty acid, erucic acid contained in the rape seed results in the excessive accumulation of fat in the heart and thus causes heart disease, and thus may be harmful to human body. Furthermore, depending on the kind and constitutional ratio of the components in the feed composition for broilers a severe nutritional imbalance may be caused, which may cause problems of the type in which the resistance of the broiler to disease is weakened, and the taste of the feed composition, digestion and absorption and weight gain by the broiler are undesirably changed.
According to the present invention, there is provided a feed composition for a broiler, which comprises 40 to 70% by weight of a n-3 fatty acid source, 25 to 50% by weight of a carbohydrate source, 2 to 4% by weight of a fibre source and 0.3 to 0.6% by weight of an antioxidant, wherein an n-3 fatty acid is an ethylenically unsaturated fatty acid in which the first double bond of the unsaturated fatty acid is located at the third carbon atom from that end of the carbon chain remote from the caboxcylic acid group.
Preferably the n-3 fatty acid source contains little or no rape seed.
The present invention also provides a method for producing chicken rich in n-3 fatty acid and having a reduced total lipid content by supplying a broiler with the feed composition of the present invention, from 1 to 2 weeks prior to slaughtering, as finishing diet.
In devising the present invention attention has been paid to the fact that the selection and constitutional ratio of the components of the feed composition are the most important factors for increasing the proportion of n-3 fatty acid in chicken, and thus extensive experiments were conducted to find the most effective n-3 fatty acid sources and the most suitable constitutional ratio thereof through repeated feeding. As a result of such experiments, the present invention was completed.
When the feed composition according to the present invention is supplied to broiler, chicken containing high n-3 fatty acid can be obtained without any difficulty in the nutritional condition, growth rate and digestion/absorption of broiler.
Preferably, in order to provide a feed composition which can provide excellent absorption and efficiency, one or more of linseed, perilla seed and fish meal is used as the n-3 fatty acid source.
Linseed is abundant in a-linolenic acid as an n-3 fatty acid but contains little EPA (eicosapentaenoic acid) and DNA (docosahexaenoic acid). Therefore, linseed is preferably mixed with fish meal having a high EPA and DNA content. Perilla seed is not greatly different from linseed in its constituents. However, perilla seed makes the feed composition suitable to the broiler's appetite, and, further, the use of perilla seed in combination with linseed is preferred, in terms of the body absorbancy of the feed composition, in comparison with the sole use of linseed. In a preferred embodiment of the feed composition of the present invention, the n-3 fatty acid source comprises linseed and perilla seed in a mixing ratio by weight of 100:1-10.In addition, when the n-3 fatty acid source contains additionally 10 to 20 by weight of fish meal (based on the weight of the overall composition) the resulting feed composition for broilers is particularly suitable to the broiler's appetite and has a good digestion and absorption property.
In the feed composition of the present invention, the content of said n-3 fatty acid source is 40 to 70% by weight, preferably 40 to 65% by weight, of the total composition. In addition, protein and phospholipid contained abundantly in the feed composition of the present invention can assist the n-3 fatty acid to be absorbed more effectively in the broiler's body.
As a carbohydrate source in the feed composition according to the present invention, cereals such as wheat or barley can be used in an amount of from 25 to 50% by weight of the total composition.
If necessary, other components conventionally used in broiler feed compositions, such as vitamins, dicalcium phosphate and other salts can also be included in the feed composition according to the present invention.
In the feed composition of the present invention, santoquin is preferably used as an antioxidant.
Previous n-3 fatty acid-enriched feed compositions have generally been supplied to broilers for a long period. In such case, however, excessive feed cost makes the feed composition uneconomical and the growth of broiler may be often inhibited. However, according to the present invention, even when the feed composition of the present invention is supplied to broiler for only one or two weeks prior to slaughtering, chicken meat having high n-3 fatty acid and a good quality can be produced. Accordingly, the feed composition of the present invention is very
economical and shows an excellent effect.
The present invention also provides a chicken
having the n-6/n-3 fatty acid ratio of 2.0-5.0:1, which
is produced by supplying to broiler with the feed
composition of the present invention as described
above.
A detailed embodiment of the present invention is
illustrated in the following Example.
Example 1
Preparation of n-3 fatty acid-enriched feed composition for broiler
Table 1. Feed composition of the present invention
Action Components Ratio(wt.%) n-3 fatty acid o Linseed 50 and protein o Perilla seed 1 source o Fish meal 10 Carbohydrate o Wheat 30 source and taste 1 o Barley 4 enrichment Antioxidant o Santoquin 0.5 Fibrin source o Alfalfa 2.4 o Salt 0.3 o Methionine 1 0.05 Others o Dicalcium phosphate 0.7 o Vitamin mixture 1 o Choline 0.05 All components as mentioned above in Table 1 are blended uniformly in the given ratios to prepare the broiler feed composition of the present invention.
Experiment 1 : Total lipid content in each tissue of
chicken obtained from broiler fed with
the feed composition of the present
invention
Forty (40) fowls are divided into two groups. The first group (control group) is fed with a commercially available feed and the second group (test group) is fed with the feed composition of the present invention.
The feeding in each group is continued for ten (10) days. Thereafter, the total lipid content in each tissue, i.e. liver, breast tissue, leg tissue and skin tissue, of chicken obtained from the two groups is determined, and the average values in two groups are compared.
Table 2. Ratio of total lipid contents in each tissue
of broiler fed with the commercial feed
(control group) and the feed composition of
the present invention (test group)
Clsssification Liver 8resst Leg Skin tissue tissue tissue Control Test Control T Test Control Test Control Test Ratio of totel Group group group group group group group group lipid contents (n=20) 1 (n=20) (n=20) (n=20) (n=20) (n=20) (n=20) ln=Z0) 3.5 I 2.6 I 3.6 1 2.4 l 1 Note: All the numerical values mean the ratio of
total lipid content in the control group to
the total lipid content in the test group
which is defined as 1.
As shown in Table 2, the total lipid content in each tissue of broiler belonging to the test group fed with the feed composition of the present invention is decreased by 71% in liver, 61% in breast tissue, 72% in leg tissue and 58% in epidermic tissue, as compared with those in broiler belonging to the control group fed with the commercial feed. Accordingly, it is seen that the feed composition of the present invention causes a decrease of the fat accumulation in tissues of broiler and thus is effective for increase of the relative proportion of meat. Consequently, the feed composition of the present invention can produce chicken suitable to the consumer's desire.
Experiment 2 : Comparative test for the n-6/n-3 fatty
acid composition in each organ of
broiler fed with the commercial feed
(control group) and the feed composition
of the present invention (test group)
The fatty acid composition is each organ of chicken obtained in the above Experiment 1 is analyzed.
The results are as follows.
Table 3. Fatty acid composition in each organ of
broiler of the control group and the test
group
Classifi- Liver Breast Lcg Skin Adipose cation tissue tissue tissue tissue Control Test Control Test Control Test Control Test Control Test ratio (n=19) (n=131 (n=20) (n=ll) 17.0 (n=13) 3.4 (n-6/n-3) 8.7 2 11.7 3.5 11 4.3 16 4.9 17.6 3.4 As shown in Table 3, in each organ of broilers (control group) fed with commercial feed the n-6/n-3 fatty acid ratio is in the range from approximately 918::1 and therefore the content of n-6 fatty acid is significantly higher than that of n-3 fatty acid.
Contrary to this, in broilers (test group) fed with the feed composition of the present invention the n-6/n-3 fatty acid ratio in each organ is in the range 2-5:1 and thus it is identified that the relative content of n-3 fatty acid is drastically increased.
Considering the overall results of the above experiments, since in chicken produced with the feed composition of the present invention the relative proportion of meat is increased due to the decrease of total lipid content and the content of n-3 fatty acid in total lipid in each tissue is also significantly increased, in comparison to the chicken produced from broilers fed with the commercial feed, chicken of the present invention is very advantageous to the consumer's desire. Thus, chicken of the present invention is rich in n-3 fatty acid. Therefore, various physiological disorders caused by excessive n-6 fatty acid intake can be prevented by intake of such chicken. Further, since n-3 fatty acid absorbed in the human body inhibits the metabolism of n-6 fatty acid, physiological sequelae due to the excessive intake of n-6 fatty acid, particularly arachidonic acid, contained abundantly in human diet can also be treated, and the physiological balance of human body can be maintained by adjusting the n-6/n-3 fatty acid ratio.
