Means and processes for promoting the growth of animals for slaughter

The invention relates to means for feeding slaughter animals and for accelerating growth the same. It relates in particular to an agent that has a growth-accelerating effect, when administered orally to live animals for slaughter, including poultry.

The smock according to the invention is calibrated orally verabable Means which can be adapted to the digestive system of the respective type of mountain and as an active ingredient genebilic acid and / or contains at least one of the non-toxic salts of genebilic acid.

It has been found that oral administration of such an agent to an animal has a remarkable effect the growth of the animal has. In comparison with an animal fed the same amount of feed, ingests Animal to which the active substance is administered grows faster. It is also possible to have an animal given the active substance to feed with a lower quality putter and still have one to achieve good growth rate. It was also found that the addition of the active ingredient in animals has the effect that the required amount of feed per animal can be reduced without the growth rate would be noticeably impaired.

These effects can bring significant savings to an animal breeder.

The growth-promoting effects of the active ingredient when added orally are surprising insofar as the grenebilic acid does this Does not have any effect when injected into the bloodstream of animals.

The oral addition of the active ingredient has no disruptive or with adverse side effects on the animal. Even after being added for a long time, the active ingredient does not become in the animal body accumulated; there are also no other effects that would affect the Would reduce the value of the carcass as a source of meat.

The formula for g-enebilic acid is:

COGH ₂ CH ₂ GOOH

The acid's diethanolamine salt is a suitable salt, though other salts of genebilic acid which are non-toxic to the animals in the amounts administered can also be used can. It has been found that the active ingredient in general

109839/0386

• It is best given to animals in an amount that the animal between about 1 "to about 40 mg of acid per kg of body weight and day.

The agent according to the invention can be administered to the animals in various ways. For example, it can be added to feed or drinking water. Another '' ^r ec is to provide the active ingredient in a "brick" or block with a releasable, non-toxic and compatible with the digestive system of the animal binding agent to bind and in this way a "leak-brick" au, ie, a Block on which the animals can lick and in this way ingest the active substance.

The active ingredient can be added to most animal feed will.

In the case of solid feed in the form of pellets, nuts, In cakes or grains, the active ingredient can be mixed with the feed in powder form or in particle form, or An aqueous solution of the active ingredient can be applied to the feed be sprayed. Suitable feed can be selected from a "wide range of substances." Examples are edible meal, edible wheat flour and all types of grain.

However, the active ingredient can also not be used with a suitable one toxic carriers or diluents that are compatible with the animal's digestive system are mixed, to form a consume which is then mixed with a feed to obtain the desired concentration of active ingredient in the feed. Am so-

The concentrate can contain the active ingredient and a carrier or a thinning siaitt el containing, for example, fish meal, meat or bone meal, soy meal, Gracmehl ,. lime or inorganic feed additives such as Lime flour, mineral salts such as sodium chloride or other nutrient salts including those of trace enrae tall en. and vitamins are.

The active ingredient can · also with just one component of the daily Mixed feed. In this case, the proportion of the active ingredient must be increased accordingly to the to give the required daily addition amount.

In the case of liquid feed, such as milk for young animals, can the active ingredient must be added in the form of a solution.

If the active ingredient is to be added to the drinking water, it can be advantageous if the agent according to the invention placed on the market and stored in the form of a concentrated and preferably saturated aqueous solution will. A certain kenge of this aqueous solution becomes the Drinking water added in order to obtain a concentration of the active ingredient "which is adapted to the animal that uses the water drinks. Such a concentrated solution can at least 100 g of genebilic acid and / or its saltec (calculated in the form of the acid) per liter of solution. The active ingredient can also advantageously be in the form of a suspension sold and stored in water.

Among the many animal species in which the desired one growth-promoting effect of the active ingredient found are cattle, pigs, sheep, rabbits bred for human consumption and poultry such as Kühner and Turkey.

The amount of active ingredient to be administered to the animals depends on the Age of the animals. For example, the pose tightness is of the active ingredient in day-old calves and piglets approx. 0.3 g acid per pound (Ib) of the feed , per day (0.662 g acid per kg feed per day). In the event of from pigs weighing 45 kg (100 lbs). to Bacon weight is the preferred level 0.1 g acid per Ib of the feed per day (0.22 g Acid per Ib of the feed per day (0.22 g acid per kg of feed per day).

The following test descriptions contain results, obtained with the invention in pigs.

Attempt 1

The first attempt was made to determine whether by using Genebil as a feed additive an effect may or may not be achieved. TJm so many To eliminate variable factors as much as possible, all animals selected for this experiment were female. They were raised under identical conditions in the group system. Twenty pigs were in each Section used and the factors determining the environmental conditions were constant for both groups.

Feeding;

A mästration ("bacon ration") was fed everywhere, and in the experimental group Genebil was added in an amount of 224 g per ton of mästration (227 g / t mästration), so that a level of 500 mg per 5 Vo of feed

(220 rag per kg of feed). This mixture was generated by first adding a part by weight ("one -p.b.w. part" "J each with 226 parts by weight ("p.b.w.") of "pork concentrate" Was mixed well and then this mixture in the mästration, which fed to the Yersuchsgruppe was used. The ration was fed in amounts of 2.27 kg (5 lb) per pig per 1.36 lag kg (3 Ib) in the morning and 0.90? kg (2 Ib) in the evening.

The composition of the mästration ("bacon ration") was the following:
