Productivity of chicken broilers for introduction of saccharomyces cerevisiae yeast in fodder feed
Currently, there is a problem of obtaining environmentally friendly products that do not harm people.
For many years, the main means of controlling the intestinal microflora of birds were feed antibiotics. However, they have a number of significant disadvantages, in particular, the ability to accumulate their residual amounts in poultry products and the development of resistance and adaptation of microorganisms to these drugs as a result of their long-term use.
Information has emerged in the scientific literature based on research on the accumulation and storage of antibiotics in organs and tissues after slaughter. These negative aspects of the use of antibiotics encourage livestock producers to look for new drugs to stimulate the growth and development of broiler chickens, instead of banned in Europe feed antibiotics.
As a result, we have increased research in the country and abroad on the study and development of drugs, alternative antibiotics. These include probiotics and enzyme preparations.
The introduction of probiotics in the technology of growing young animals is the most modern way of prevention of gastrointestinal diseases, based on environmentally friendly mechanisms to maintain a high level of colonization resistance of the intestine. The use of enzyme preparations can increase the number of beneficial bacteria in the intestine, have a positive effect on putrefactive and opportunistic microorganisms of the gastrointestinal tract, and improve the composition of the microflora of the digestive tract (Isolauri et al., 2001; Czap & Orishhuk, 2015).
Studies aimed at studying the effect of feed yeast drug, both individually and in combination with a probiotic complex on the productivity and quality of broiler meat, are relevant, of great scientific and practical interest.
It is proved that their introduction into the diet of broiler chickens helps to increase productivity and improve the digestibility of nutrients in the diet.
