Abstract
The article draws attention to the fact that the vitamin feed additive Introvit A+WS is an effective complex in its composition, consisting of 12 fat-and water-soluble vitamins, 18 essential and replaceable amino acids and 9 macro-and microelements that affect not only stability to various infectious diseases, but also to increase the meat productivity of young poultry. In recent years, industrially produced vitamins have become increasingly widespread, as well as feed additives used as a means of increasing animal productivity, reducing the cost of protein feed and increasing the efficiency of using feed nutrients. The vitamin feed additive Introvit A+WS in the indicated doses under production conditions had a positive effect on the weight gain of broilers and on the preservation of the poultry population, therefore, it shall be widely used in industrial poultry farming.
Highlights
A promising direction in increasing the productivity of poultry is the preservation of natural defense mechanisms inherent in poultry from nature, allowing in industrial conditions to keep adequately without losing productivity to respond to stress factors, to a lesser extent to be exposed to diseases of various etiologies [1,2,3]
The vitamin additive Introvit A+WS used by us in the experimental group is a watersoluble powder containing a complex of vitamins, amino acids and microelements
In the experimental group, where the vitamin feed additive Introvit A+WS was used in young poultry, significant increases in the live weight of broiler chickens were revealed compared to the live weight of chickens in the control group on the 7th, 14th, 21st, 28th th, 35th and 45th days of growing
Summary
A promising direction in increasing the productivity of poultry is the preservation of natural defense mechanisms inherent in poultry from nature, allowing in industrial conditions to keep adequately without losing productivity to respond to stress factors, to a lesser extent to be exposed to diseases of various etiologies [1,2,3]. Various feed additives increase the body's resistance to technological stress. They remove the negative immunosuppressive effect of vaccine drugs [4,5,6,7,8]. For example, the food additive Neokolistin – a watersoluble powder containing colistin, neomycin, tylosin and a set of vitamins, is used for therapeutic and therapeutic purposes for colibacillosis, pasteurellosis, salmonellosis, respiratory and other infections, the causative agents of which are sensitive to the components of the drug. The food additive Altisal-tm 1000 is prescribed for the treatment of poultry and pigs with gastrointestinal and respiratory bacterial infections caused by pathogens sensitive to tylosin. The feed additive Intromin Oral is used to balance the diet for missing minerals, to increase the digestibility and assimilation of nutrients
