Summary. The aim of the investigation was to study the influence of fodder containing mannanoligosaccharides (MOS) on the carriage of Salmonella in poultry and increase in live weight. For the experiment 2 groups (n = 20) of one-day-old chickens of egg productivity direction of the cross Iza Shaver 579 were formed on the principle of pair-analogs. The fodder substance containing MOS was included in the diet of the experimental group at 2 % of the total fodder weight. For the experimental infection by salmonellosis all chickens were orally administered by daily culture Salmonella spp. Every week chickens were weighed and control slaughter was done (n = 5). To determine the total contamination of Salmonella the bacteriological culture from the internal organs: liver, pectoral muscles, the contents of the small and large intestine, was taken. Daily application of the fodder substance to chickens reduces the carriage of bacteria of the genus Salmonella. In chickens from the experimental group Salmonella spp. were found in 5 % of liver samples, in the control group – in 48.5 %; in colon content – in 15 % and 53.3 %, correspondingly. Average daily gain of the chickens from the control group increased by 58.85 % compared to the control to the 30th day. The economic efficiency of application of the fodder substance containing MOS for chickens at the daily dose of 2% of the fodder weight for 30 days was 8.9 rubles per 1 ruble of the costs.
Keywords: mannanoligosaccharides, chickens, microorganisms of the genus Salmonella, carriage of bacteria, increase in live weight.
