Feed additive for small animal breeding and method for improving meat quality.

The invention relates to a feed additive for the breeding of small animals, in particular the keeping of poultry and rabbits, and further to a method for improving the meat quality, in particular the taste of poultry meat.

It is known that the meat of small livestock, which is predominantly or exclusively fed with artificially prepared feed mixtures, has an unspecific, somewhat vague taste and often even an unpleasant aftertaste. Broiler cocks fed with 10 lots of fish meal, for example, taste like fish.

This is particularly the case with intensive keeping of the animals.

The poultry kept under extensive conditions in the yard or in the garden covers its food requirements from very different natural sources and the additional feed given is also very rich in variety: grains, maize, potatoes, kitchen waste, food residues, etc. In addition, various plant parts, such as grass, weeds, leaves and seed grains? worms, insects and small vermin complete the broad spectrum of food sources, which give the meat of the domestic fowl its characteristic flavor.

The meat of the animals fed in artificially prepared concentrates mixtures in intensive poultry farming has, as is generally known, a less good consistency, a weak taste and often an unpleasant aftertaste. In the first place, this can be traced back to the reported factory-prepared feed mixtures, including their composition (eg fish meal), the biological and chemical changes occurring in the feed mixtures (eg becoming rancid, mold, protein decomposition) and the medicines, chemicals and the weight gain increasing agents added to the feed mixtures. Medicinal substances and biologically active substances are often used in the feeding, without taking into account 8201430 - 2 - how much these agents affect the taste of the meat.

Numerous additives and additives are known for increasing the yield of meat, even for improving the consistency of the meat, but no means are available on the market which could favorably influence the taste of the meat. Partial solutions have been developed for the separate subproblems, for instance to combat the unpleasant aftertaste of roasters fed in factory poultry feeds with factory-prepared feed mixtures, but partial solutions have not found practical application on these or other grounds. For example, it has been found that the fish-like off-taste of chicks fed fishmeal for 4 weeks can be controlled by adding 80 IU Tokoferol (vitamin E) to the feed mixture. However, this addition is too expensive for poultry farming on a large scale. Sulfur-containing compounds which would change the taste of the meat have also been reported in the American specialist literature. Attempts were also made to add to the animals, in addition to the artificially prepared feed mixtures, the natural substances necessary to achieve the natural meat taste, but these attempts also had a negative result. The reason for this lies in the fact that in intensive poultry farming the animals can be switched over to the use of other types of nutrients only very difficult and at the expense of the weight gain.

The object of the invention was therefore to find a feed supplement which improves the taste of the meat of small livestock, in particular of poultry, and to further develop a method with which this feed additive is used in intensive poultry farming. can be fed in an easily digestible form.

It has now been found that certain flavorings and flavorings of vegetable origin, furthermore the compounds present in vegetable flavorings and / or their components, favorably influence the taste of intensively kept animals, eg of chickens, geese, turkeys, rabbits.

The object of the invention is therefore a feed material supplement which is used in the animal organism, which has a favorable influence on the taste of the meat and which is furthermore possibly obtained from at least two different vegetable flavoring substances. compounds and optionally flavor enhancers present in other vegetable flavorings and / or their components.

The object of the invention is furthermore a method for improving the meat quality, in particular the taste of poultry meat. It is characteristic of the method that, in the case of intensively reared animals, in the case of multi-stage rearing, feed is only carried out in the last phase, in the amount of 10-400 mg per kg body weight, in the last phase. -admix additive, which is used in the animal organism, has a favorable effect on the taste of the meat and, if necessary, from at least two different vegetable flavorings. compounds present in 15 other vegetable flavoring substances and / or their components and, if necessary. flavor enhancers exist.

As flavor and aroma substances of vegetable origin are eligible: cinnamon, lemon, orange, anise, cumin, onion, garlic, eucalyptus, coriander, 20 celery, thyme, ginger, parsley -, parsnip, geranium and ilang-ilang oil, as well as mixtures of these components.

The feed additive according to the invention may further contain compounds which are present in vegetable flavoring substances or their components, but which can also be prepared synthetically. As examples of such compounds can be mentioned: d-limonene, anisaldehyde, diacetyl, carvone, protocatechaldehyde methylene ether, ethyl butyrate, benzyl butyrate, geronyl acetate, selinene, vanillin, cymol, 3,4-menthen, n-decylaldehyde, terpinolene, terpinolene , carvomen-30 thol, terpineol, eucalyptol, eugenol, d-camphene and cinnamaldehyde.

Preferably, the feed additives according to the invention also contain flavor enhancers, which synergistically enhance the action of the flavoring substances. Suitable flavor enhancers are, for example, lavas oil (lavas = Levisticum officinale) and glutamate. The flavor enhancers are preferably added in an amount of about 2%.

The composition of the feed additive 8201430 - 4 - ί> is chosen depending on the effect to be achieved. For rabbits food additives, a different composition is optimal than for geese or turkeys. Different compositions can also be optimal for one and the same poultry species: a different composition is required for rearing broiler geese than in the case of broiler geese, the main product of which is the large goose liver.

The inserts according to the invention contain at least two different flavoring substances of vegetable origin. When using only one flavoring substance or only synthetic components, the result is less satisfactory.

The additives according to the invention can also have a beneficial effect on food digestion, result in a greater feed intake and in some cases also make less valuable or per se suitable feed suitable for feeding. However, these effects are secondary and cannot be pursued in any case. The primary effect of the additives according to the invention consists in the fact that the meat of the animals has a pleasant, characteristic taste, which resembles the taste of animals reared extensively with versatile natural food. To achieve this effect, 1Q-4Q0 mg of the feed additive according to the invention is added to the factory-prepared feed mixture per kg body weight.

The addition of the feed supplement does not necessarily have to take place throughout the entire breeding period. The intensive keeping of chickens, for example, takes place in three phases; a) in the first phase up to the age of 3-4 weeks, a so-called "culture feed" is administered, which generally shows a higher protein content (23%) and stimulates the digestion, increasing the weight gain substances, eg Zn -barithracin, coccidiostats (flavomycin) and contains 3000-3200 kcal metabolizable energy. The culture feed also contains 1% calcium, 0.8% phosphorus, as well as vitamins A, D, 35 E and K, the amount of which is reduced in the later phases.

b) The feed given in the second phase, from the third to 8201430 * - 5 - fourth week, already contains less protein (20%) and the calcium and phosphorus content is also lower (0.9%, respectively 0, 6-0.7%). The amount of the fat-soluble vitamins is less, however the content of vitamin B remains unchanged, resulting in an unpleasant smell and taste. The premix also contains selenium and biotin.

c) In the sixth, seventh and eighth weeks, so-called "closing food" is given, which contains 16.5-17% protein. The fat-soluble vitamins are only administered in a minimum amount of 10. The premix does not contain selenium, the content of vitamin E remains unchanged.

Tests have established that it is sufficient to use the feed additive according to the invention only in the third phase, i.e. to mix it in the closing feed. The meat of the cocks resembles the meat of the cocks kept under extensive, natural conditions.

The feed additive according to the invention can be used successfully in breeding for broiler roosters, meat geese, foie gras, turkeys and rabbits.

The invention is further illustrated by the following examples.

EXAMPLE I

25 In the three - stage rearing of

Broilers is cultivated feed, respectively in the first two phases. given the usual food in the second phase. In the third phase, 28 mg of flavorings in the form of a solution prepared with 280 ml of alcohol are added to 1 kg of closing feed and homo-30 is not mixed with the feed. Each cock gets 1.5 kg in total from this feed in 7 days.

The flavor addition has the following composition: 60% barbacue (mainly contains onion oil, 35 resp. Components thereof) or onion oil 20% cumin oil 10% parsley oil 8% diallyl sulfide 2% lava oil.

8201430 - 6 -

The components are dissolved in 90% alcohol and mixed with the feed in this form.

In order to estimate the effect, the meat of the Broilers is examined organoleptically. Control 5 is a group of animals fed without flavoring substances and, as standard, the meat of roosters kept under extensive conditions. Tasting of the animals prepared in the kitchen showed that the meat of the animals fed with flavored food resembles the standard in taste.

EXAMPLE II

Meat geese are fed in the second (and thus final) phase of the rearing phase with a feed containing the following flavor additives: 50% barbacue 15 20% ginger oil 10% celery oil 10% allylpropyl sulfide 8% cinnamaldehyde 2% glutamate. the above composition was added to the feed in an amount at which the geese absorbed 25 mg of supplement per kg body weight up to maturity.

EXAMPLE 'XII

For the rearing of geese, which have the largest possible and good tasting liver, the geese are fed as described in example II, with the difference, however, that the addendum has the following composition: 40% barbacue, 30% anise and Koreander extract, 25% cod liver oil and soybean oil, 3% geronylacetate, 2% lavas oil.

The amount of supplement is adjusted such that the animals absorb 30 mg of supplement per kg body weight.

EXAMPLE IV

The breeding of turkeys is done in 8201430-7 according to the method described in example II, with the difference that the animals absorb 20 mg of an adjunct with the following composition per kg body weight: 50% barbacue 5 40% walnut oil

10% arachis oil EXAMPLE V

Rabbits are fed for the entire duration of the intensive keeping with a feed containing as an addition a mixture of the following composition; 10% parsnip oil 20% parsley oil 10% coriander oil 30% cumin oil 15 25% walnut oil 3% gerony acetate 2% lava oil.

The amount of the additive was adjusted so that the animals absorb 30 mg of additive per kg body weight.
