Abstract

This article reflects the results of a study on feeding an experimental group of laying hens for 1–14 days with full-fledged compound feed, additionally containing heterologous lactobacilli with anti-C. jejuni activity as a feed additive. Data were obtained on the sowing rate of target lactobacilli from poultry manure and eggs. The eggs were collected for the production of broiler chickens. As a result of the studies, it was concluded that the use of a feed additive based on heterologous lactobacilli contributed to an increase in egg production per hen – by 7,8–10%, and egg-laying intensity – by 5,7–7,3%. The addition of the additive had a zootechnical effect even after a single application. The introduction of a feed additive based on lactobacilli, in general, had a positive effect on the productivity of the parent hens.
