Abstract

FIELD OF THE INVENTION The invention relates to a host economy and can be used in the feed industry in the preparation of fodder c. the inclusion of chlorella microalgae. The purpose of the invention is to increase the nutritional value of the feed. Chlorella biomass dispersed to a size of 0.2-0.4 mm and dry matter content of 20-100 g / l, dispersed to a size of 0.2-0.4 mm, is introduced into the straw concentrate, mixed for 5-10 seconds and granulated at a temperature of 70-80 C. The granulated feed contains up to 1800-2500 mg / kg carotene on a dry matter of chlorella. The coefficient of digestibility of the granulated feed mixture increases in comparison with the feed mixture without granulation by 12.8-13.5%.

The invention relates to agriculture and can be used in: feed industry during the preparation of feed with chlorella,

j The purpose of the invention is to increase the nutritional value of feed,

Example 1. In a straw-concentrate mixture of 00% straw of winter wheat Beyust -1 and 30% grain h) with a moisture content of 8-10%, if it becomes constant, a dispersion is applied to the granulator mixer with the help of a distributor up to 0.2-0.4 mm chlorella biomass with a dry matter content of 20 g / l. The mixture is stirred in a granulator mixer for 5 seconds and granulated at 70-80 ° C.

; The granulated straw-concentrate mixture contains chlorella in the amount of 2.5 g / kg of feed with a ruptured cell wall.

The content of carotene in the feed mixture is increased by 6 mg / kg of feed, and the yield of detectable carotene in terms of dry matter of chlorella is 2500 mg / kg. The interruptibility coefficient of the granulated fodder mixture is increased by 12.8% compared with the introduction of a suspension of chlorella into the concentrate concentrate without further granulating,

 Example 2. The method is carried out analogously to example 1, except for eifi, that the chlorella biomass is introduced into the straw-concentrated mixture with a dry matter content of 70 g / l and mixed in the granulator mixer for 10 s, the granulated straw concentrate the mixture contains chlorella in

Lichene 10 g / kg with destroyed cell wall. Carotid content. in the feed mixture is increased by 20 mg / kg of feed, the yield of detectable carotene in terms of dry matter of chlorella is 2100 mg / kg. The coefficient of digestibility of the granulated feed mixture increases by 13.5%.

Example 3. The method is carried out analogously to example 1, except that the chlorella biomass with a dry matter content of 100 g / l is introduced into the straw / concentrate mixture and the mixture is granulated.

The granular straw-concentrate mixture contains chlorella in the amount of 15 g / kg of feed with destroyed cell wall. The carotene content of the feed is increased by 27 mg / kg. The yield of detectable carotene, calculated on the dry matter of chlorella, is 1800 mg / kg. The coefficient of digestibility of the granulated feed mixture is increased by 13% compared with the feed mixture without granulation.

Claims (1)

Invention Formula A method for preparing animal feed, which includes mixing the dry components of the feed, introducing a liquid component into them and granulating, characterized in that, in order to increase the nutritional value of the feed, the biomass of chlorella with a dry matter content of 20-100 g / l is used as a liquid component, dispersed to a particle size of 0.2-0.4 mm, and mixing is carried out for 5-10 seconds.
