Effects of phytoprobiotic complexes on the biochemical profile of broiler chickens’ blood serum

In order to regulate metabolism in poultry farming, a wide range of different methods and methods are offered. Special attention is paid to preparations and feed additives obtained on the basis of phytobiotics. In this regard, the purpose of these studies was to study the effectiveness of the effect of Echinacea purpurea extract in combination with the probiotic drug Subtilis-C on the biochemical parameters of blood serum in broiler chickens. The research was conducted on Cobb-50 broiler chickens in two scientific and production experiments in the Republic of North Ossetia-Alania. In the first scientific and production experiment, the optimal dose of administration of echinacea purpurea extract into the diet was established, in the second, the effectiveness of combining echinacea extract with the probiotic Subtilis-C was studied. During the second scientific and production experiment, a decrease in serum cholesterol by 27,23 % or 0,61 mol/l (P<0,05) was found, which may be a warning factor of excessive fat deposition, while the use of the tested drugs is accompanied by a significant increase in glucose by 7,23 % (P<0,05), aspartate aminotransferase (AsAt) and alanine aminotransferase (AlAt) up to 9,73 % and 7,17 %, respectively, During the experiment it was shown, It is shown that the combined use of the phytoprobiotic complex under study has a positive effect on the biochemical profile of blood serum and, in general, on the metabolic processes in broiler chickens, and also contributes to the formation of marketable carcasses. The optimal dose and regimen for broiler chickens is the administration of Echinacea purpurea extract at a dose of 5,5 mg/kg body weight in combination with the probiotic Subtilis-C at a dose of 0,3 kg/ton for pre-start and starter feeds; and 0,15 kg/ton for finishing feeds.
