METHOD FOR PREDICTING THE PRODUCTIVITY OF POULTRY BY THE COMPOSITION OF THE MICROBIOME AND THE ACTIVITY OF ENZYMES OF THE GASTROINTESTINAL TRACT Russian patent published in 2023 - IPC A23K10/30 G01N1/00 

FIELD: agriculture.

SUBSTANCE: invention relates to poultry farming, and is a method for predicting the productivity of poultry by the composition of the microbiome and the activity of enzymes in the gastrointestinal tract at an early age. The method for predicting the productive qualities of broiler chickens based on the percentage of Lactobacillus bacteria and the activity of amylase in the litter of broiler chickens differs in that the productivity index is used as an evaluation criterion when predicting productive qualities, which is calculated by formula , where K is the coefficient of enzyme activity, units; A – amylase activity in litter, mg/(mL×min); L is the percentage of Lactobacillus bacteria from the total number according to the results of high-throughput sequencing of the 16s rRNA gene; at I≤14.3 broiler chickens belong to the group with high productive qualities.

EFFECT: invention can be used to timely adjust feeding rations, achieve effective weight gain and increase the profitability of the poultry farm.
