Effect of Bacillus cereus IP 5832 and coumarin in the diet on the general state of the broilers

Currently, there is an interest in complex biological preparations based on probiotic strains and plant extracts. Probiotic preparations, together with plant extracts, are natural growth stimulants and can become a promising replacement for antibiotic growth stimulants in poultry farming, the latter stimulate the production of endogenous enzymes, improving the digestibility and absorption of nutrients in feed. Technological prospects for the probiotics and plant extracts practical joint use in poultry farming touch upon a wide range of problems related to the correction of intestinal biocenosis, hormonal and enzymatic systems, stimulation of immunity, prevention and treatment of dysbacteriosis. The purpose of this study is to assess the effect of the complex introduction of the probiotic strain Bacillus cereus and a coumarin derivative in the diet of broiler chickens on hematological parameters. In the studied broiler chickens, changes in hematological and biochemical parameters are noted in connection with the processes of their growth and development. All parameters in the blood are accompanied by changes, which indicates an intense metabolic rate, an additional load in the metabolism that requires the participation of protective blood elements.
