Abstract
The uncontrolled use of antibacterial drugs resulted in a wide spread of forms of microorganisms resistant to them. The resistance of most bacteria to one degree or another is observed in relation to almost all existing antibiotics, which led to a significant decrease in the effectiveness of their use not only in veterinary medicine but also in medicine. Therefore, an important task which veterinary service faces is the use of alternative antibacterial drugs. Thus, the development and use of prebiotics in the food of poultry for complete or partial replacement of antibiotics is considered as a new direction of modern scientific research. The authors were the first who studied the effect of the heteropolysaccharides “raspol” and “vetelac” on the organism of broiler chickens. A high pharmacological effect of both drugs was established with a clear advantage of raspol, the use of which, against the background of the absence of antibiotics, had a positive effect on the growth and viability of poultry and caused an increase in the natural resistance of organisms. Thus, prebiotic raspol can be used as an alternative to antibacterial agents in broiler poultry farming. This drug is recommended for the give to broiler chickens with water at the rate of 0.6 g / kg of body weight starting from 7 days of age for 10 days.
Highlights
The concept of prebiotics is relatively new in the science of functional nutrition and continues to develop using advances in molecular genetics, metagenomics, metabolomics and analytical chemistry
The main criterion is the chemical structure of prebiotic molecules, which determines their resistance to digestion in digestive tract and the ability to ferment by certain groups of intestinal bacteria
The research purpose is to study the effect of the prebiotics “Raspol” and “Vetelac” on the organism of broiler chickens in order to offer these drugs as an alternative to antibacterial ones in the diets of poultry
Summary
The concept of prebiotics is relatively new in the science of functional nutrition and continues to develop using advances in molecular genetics, metagenomics, metabolomics and analytical chemistry. A new direction of modern scientific research is the development and use of prebiotics in feeding farm animals (poultry) as an alternative to antibacterial drugs, since the entry of domestic agricultural products to the foreign market provides for the absence of antibacterial drugs in products and raw materials of animal origin [8,9,10] As it is known, the nutrition of the saprophytic microflora of the intestine of farm animals (poultry) and its normal functioning fundamentally depends on the supply of polysaccharides to it, which, under the action of the intestinal microflora, undergo fermentation with the formation of short-chain fatty acids (propionic, butyric, acetic), which in turn have a pronounced antiinflammatory and anticarcinogenic effect [11]. The research purpose is to study the effect of the prebiotics “Raspol” and “Vetelac” on the organism of broiler chickens in order to offer these drugs as an alternative to antibacterial ones in the diets of poultry
