Poultry feed and its production and use

The present invention relates to a poultry feed having an increased pigmentation effect as well as its production and use,

Recently, consumers have increasingly wanted eggs with a deep yellow yolk, on the other hand the poultry is increasingly deprived of the greenery required for normal pigmentation.

It is known that adding paprika to feed increases pigmentation. According to the present invention, it has now surprisingly been found that paprika in hydrolyzed form has a considerably improved pigmentation effect compared to unhydrolyzed paprika. That The feed according to the invention is accordingly made by adding hydrolyzed paprika or an extract or an aqueous dispersion thereof.

The feed according to the invention is preferably composed of a mixture of conventional poultry feed (complete feed or mixed feed which can be administered with the addition of grain) with hydrolyzed paprika. The finished feed usually contains about 0.05 -. 1.0 wt% hydrolyze peppers, depending on the quality of the starting material and the desired intensity increase Pigmentierungswirkung, based on that of the basic feed.

The inventive feed can be prepared by simple admixture of hydrolyzed paprika, for example, be made of a dry powder or a hydrolyze pepper extract or an aqueous dispersion peppers to a basic feed or to the drinking water in the form. For the purposes of this invention, a drinking liquid should therefore also be referred to as food

term means are subsumed. The above-mentioned dry powder, extracts or dispersions can also be used in stabilized form, e.g. embedded in gelatine, are used. ·

A feed obtained according to the above information can be fed as usual. In the Feeding laying hens will be an appealing one, ever after the concentration of the hydrolyzed paprika in the putter, the egg yolks are more or less deeply colored achieved. Also on the pigmentation of poultry hydrolyzed paprika has a positive influence. It is beneficial, especially when the forage is poor in pigmentation active ingredients, except hydrolyzed Paprika as an additional source of pigment yellow carotenoids, such as ρ-Αρο-δ'-carotenic acid ethyl ester, to add.

The production of hydrolyzed paprika can be carried out in a manner known per se by conventional alkaline Saponification methods take place. For economic reasons it is advisable to use alkalis, such as caustic soda or potassium hydroxide, or alkaline earths as the saponification agent, like calcium hydroxide. To protect the peppers, it is advantageous to work under air and Exclusion of light and near room temperature. In addition, it is useful that you are in a

Working environment in which the pigmentation substances are at least partially soluble. A purely watery one The milieu is therefore unfavorable, which is why an alcoholic milieu is expediently used.

example 1

1 part by weight of finely powdered paprika is mixed with 2 parts by weight of methanolic potassium hydroxide solution added and the resulting mixture stirred for 4-5 hours at room temperature in a stirred tank. the Saponification solution is neutralized with phosphoric acid, the alcohol evaporates and the residue dried. This dry powder can be fed directly.

To produce an extract, the saponification solution obtained according to the above information is treated with a Solvents such as ether, gasoline, ethyl acetate, chloroform, etc., extracted and then the solvent evaporates.

Example 2

100 - 200 g of paprika become 10 # methanolic with 1 liter of a mixture of 5 parts by volume ■ Potash lye, 5 parts by volume of ether and 1 part by volume of water

• Shaken for 30 - 60 minutes at room temperature. The mixture is filtered and 700-1000 ml of water are added to the filtrate, so that the ether separates out. The phases are separated, the aqueous alcoholic phase is extracted with 500 - extracted 1000 ml ether and the combined ether extracts washed three times with 100 ml of water ie neutral. After evaporation of the ether, hydrolyzed paprika extract is obtained, which is suitable for the production of stabilized dry powders.

According to the above information, paprika extract can also be hydrolyzed.

The feed produced according to Example 3 was fed to groups of laying hens (hybrids). Four days after the start of feeding, the egg yolks were darker in color. After about The final color value was reached within 14 days. It turned out that the color increase compared to a none feed containing hydrolyzed peppers No. I weak, at No. II medium and at No. III was very strong. The resulting increase in color was clearly
