Abstract

The paper presents the results of the study of morphobiochemical, clinical-zootechnical and histological parameters of the organism of broiler chickens of KOBB-500 cross against the background of application of probiotic supplement “BACELL-M®”. The poultry population (n=10) was divided according to the principle of pair-analogs into experimental (n=5), with inclusion of probiotic additive in the diet and control (n=5) groups - diet without probiotic additive. Both groups were fed with “BEST®” brand mixed fodder. It is found that introduction of this additive into the diet of broiler chickens of the experimental group in the dosage of 100g of probiotic additive per 1 kg of mixed fodder improves general blood parameters, histological development of organs and directly affects productivity in the form of weight gain in comparison with the control group of birds. Due to the introduction of the studied additive in the diet of young poultry blood parameters were in the range of norm, in clinical and zootechnical parameters productivity was higher, as well as the additive improved the growth and development of the spleen. Thus, probiotic additive “BACELL-M®” can be recommended for use in the technology of growing broiler chickens.
