SE463391B - Method for producing an energy-rich feed supplement and the animal feed thereby obtained - Google Patents

Abstract

The present invention concerns a method for producing a feed supplement for animals with high energy requirements, and such a feed supplement, in which a combination of cooked, unhusked cereals is dried, ground and placed with 3 to 50% by weight of fat under pressure.

Description

2 High-intensity mixers are first mixed with a combination of 10 15 20 25 30 35 The mixture a starchy pelvis boiled oats, boiled wheat and / or boiled barley. which now contains glucose and galactose involved in serial powder is added in one and the same step with a fat blender. consisting of animal and / or vegetable fats mixed with an emulsifier and / or an antioxidant.

By the above procedure, very high-energy "free- -flowing "products are produced with, for example, a fat content of up to 50%.

Additional characteristics are stated in the relevant requirements.

By boiled above is meant a heat treatment during the supply of water in the form of direct steam under pressure or in the form of co- water, whereby the water content of the starch increases from malt about 10% to at least 18% or more, the starch being the grains undergo a swelling.

The present feed constitutes a larger or smaller part of the mink feed state, which otherwise includes products with animal origin.

The high-energy starch feed can, for example, with great part is added especially mink females during pregnancy and after puppy to compensate for the puppies' large energy intake. Far- starch feed was used especially in the autumn before fur when the animals have a relatively large feed intake and when horizontal feed provides a cheaper feed compared to conventional in cereal feed. f - The invention will now be described in more detail with reference to the examples below without, however, being limited to.

EXAMPLE 1 44 kg of barley and 52 kg of wheat, both unpeeled, were co-cooked to full constant gelatinization. After drying and grinding was added 4 kg of fish oil (solder oil) by the atomized oil 10 15 20 25 30 463 391 3 under pressure is mixed into the feed while stirring. Before involving of the oil, it can advantageously be mixed with an emulsifier and / or an antioxidant. This facilitates the animals' possibility to utilize the fat to the maximum at the same time as possible the tendency to rule is counteracted.

EXAMPLE 2. 50 kg of unpeeled barley and 43 kg of unpeeled wheat were cooked separately to complete gelatinization and combined. Then dry The cereal mixture was added and ground and 4 kg of fish oil (herring oil) in the manner specified in Ex. 1 above, and product was extruded under gentle treatment (heat in the form of steam) to obtain pellets, 5-10 mm.

In connection with the compaction, additional fat (1-15%) can be the pellets are passed by spraying.

EXAMPLE 3.

The procedure of Example 2 was repeated, but pellets obtained ground into a fine flour after the final greasing.

EXAMPLE 4 500 l of whey with a dry matter content of 5-6% was added lactase (0.2 ml / l Lactozyme R 3000 L, Novo) and fermented for 10 hrs at 22 ° C. In connection with the spray drying involved 150 boiled and unpeeled wheat and 120 kg of fat in the form of oil. 465 391 4 10 15 20 25 Analyzes Example 1 Example 4 Crude protein content 9.4% 6.62 Fat content (SBR2) 7.22 40.0% Starch 62.2% 33.52 Monosaccharides - 9.52 Energy content *) Total, kcal / kg 2950 5300 from protein 275 250 fat 625 3650 carbohydrate 2050 1400 *) according to the Nordic Feedingstuffs Table for fur animals 1985.

Note A product based on barley / oats / wheat contains the maximum 2500 kcal / kg. Boiled oat flakes 100% contain 3200 kcal / kg.

In the examples above, fish oil from capelin and herring has been used.

Other fats that can be suitably used are rapeseed oil, or bone fat or other good quality animal fats.
