Influence of protein-mineral concentrate together with a probiotic preparation on the egg productivity of quail

The purpose of the research was to determine the effectiveness of using a protein-mineral concentrate based on disinfected biowaste and activated zeolite together with the probiotic drug "Enzymsporin" in feeding quails. The research results showed that the use of protein-mineral concentrate does not have a negative effect on egg production, morphometric parameters of quail eggs and their microbiological safety. At the same time, the highest egg productivity was obtained in the experimental group with the combined use of BMK and a probiotic preparation.
