MICROBIOLOGICAL TREATMENT Russian patent published in 2023 - IPC A23K50/75 

FIELD: biotechnology.

SUBSTANCE: invention is a method of increasing the average daily weight gain (ADWG) in broiler chickens, comprising feeding the said broiler chickens with an amount of feed having an active ingredient consisting mainly of a Bacillus 747 strain, while the said broiler chickens have at least 3% ADWG where ADWG is at least 5%; a method for increasing average daily live weight gain (ADLWG) in broiler chickens, comprising feeding said broiler chickens with an amount of feed having an active ingredient consisting mainly of a strain of Bacillus 747, wherein said broiler chickens have at least 1% ADLWG, where ADLWG is at least 3%; a method for increasing feed conversion efficiency (FCE) in broiler chickens, comprising feeding to said broiler chickens an amount of feed having an active ingredient consisting mainly of a strain of Bacillus 747, wherein said broiler chickens have at least 6% FCE, where FCE is at least 9%; a method for increasing feed conversion ratio (FCR) in broiler chickens, wherein said method comprises feeding said broiler chickens an amount of feed having an active ingredient consisting primarily of a Bacillus 747 strain, said broiler chickens having at least 6% FCR, where FCR is at least 8%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an average daily ADWG weight gain of at least 3%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an average daily ADWG weight gain of at least 5%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an average daily ADLWG weight gain of at least 1%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an average daily ADLWG weight gain of at least 3%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an FCE feed conversion efficiency of at least - 6%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to provide an FCE feed conversion efficiency of at least - 9%; a method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to achieve an FCR efficiency of - 6% or less. A method of using a feed having an active ingredient consisting primarily of the Bacillus 747 strain in broiler chickens to achieve an FCR efficiency of - 8% or less.

EFFECT: invention makes it possible to increase the average daily weight gain (ADWG) of broiler chickens.
