“…The composition of feed mixes for poultry includes components with a relatively low availability of nutrients: wheat, barley, sunflower meal, meat and bone meal and others, which naturally reduces the digestibility and availability of nutrients in poultry diets [9,10].…”

For the first time in the Lower Volga region, comprehensive studies have been conducted to study the effectiveness of the use of compound feeds with different structures when adding cellobacterin and acidifiers to them in egg poultry farming. Their influence on the digestibility and digestibility of nutrients in diets, physiological and biochemical parameters of young and laying hens, egg productivity and egg quality, economic efficiency of production has been studied. As a result of research, the possibility of replacing animal feed with vegetable feed in compound feeds with the use of cellobacterin and acidifiers has been established, which, despite a slight increase in the consumption of compound feeds, leads to a reduction in the cost of rations per 1 laying hen to 11.48 rubles. Morphobiochemical blood parameters remain within the limits of physiological norms. The results of the studies conducted on laying hens showed that the safety of the livestock was 98%, egg production was 309.1 pieces in the control group and 310.7 pieces per laying hen in the experimental group, hematological indicators of laying hens in the control and experimental groups were almost at the same level. The consumption of compound feed for the period of experience in the control group of laying hens was 4414.41 kg in the amount of 67010.74 rubles, in the experimental group 4791.71 kg and 65886.01 rubles, respectively, that is, the difference in the cost of feed costs in favor of the experimental group was 1124.73 rubles. The production approbation confirmed the economic efficiency of the introduction of compound feeds into the poultry diet, in which animal feed is replaced with vegetable feed with the addition of cellobacterin and acidifiers.

“…Based on the results of our longterm research, we believe that probiotics should be attributed to medicines that are preferable to use for preventive therapy and as ergotropics. In our opinion, probiotics are stabilized cultures of microorganisms and their fermentation products that have the property of optimizing intestinal microbiocenoses, suppressing the growth and development of pathogenic and conditionally pathogenic microflora, increasing metabolic processes and protective reactions of the body, activating cellular and humoral immunity [7][8][9].…”

The authors conducted a scientific and economic experience in LLC "Alyona". For research on the principle of analogues from chickens of the Rhodonite-2 cross, 2 groups (400 heads each) were formed from the daily age, taking into account gender, body weight and physiological condition. The duration of rearing of the repair young was 17 weeks, after which the bird was transferred to the laying hens workshop. The planting density, light mode, and feeding front of birds of all groups were the same and corresponded to the norms of VNITIP. Feeding was carried out with the same full-fledged compound feed, balanced in all nutrients and metabolic energy, with the inclusion of a probiotic SUB-PRO in the feed mixture of the experimental group. The introduction of a probiotic into the diet when raising chickens up to 13 weeks of age ensured a higher safety of young animals in the experimental group. The addition of a probiotic reduced feed costs. During the growing period of 1-13 weeks, feed costs per 1 kg of growth were lower in the experimental group, by 3.3% for 14-21 weeks and by 3.9% during the experiment period.

The purpose of the current work was to determine the microbial composition of litter generated during the industrial rearing of broiler chickens. This is necessary in order to achieve an understanding of the influence of various microorganisms on the processing of waste products for absorption into the soil without harming and polluting the environment, for example, with bound phytate ions. The object of the study was litter sampled from under broiler chickens of different ages and parent flocks. During the study, the following groups of microorganisms were identified: peptococci (family Peptococcaceae); actinomycetes (except for the family Pasteurellaceae) from the order Actinomycetales; actinobacillus (family Pasteurellaceae); lactobacilli and enterococci (genera Lactobacillus and Enterococcus, respectively); bacteroides (phylum Bacteroidetes); ruminococci (genus Ruminococcus); eubacteria (family Eubacteriaceae) and enterobacteria (family Enterobacteriaceae). Quantitative indicators of colonies of various taxonomic groups were determined, and it was shown that these indicators changed with increasing period of litter use. Furthermore, the study revealed that the microbial composition of the litter changed over time. As the litter age increased, there was an increase in the abundance of certain bacteria, such as Peptococci and Actinobacillus, which are known to be involved in the decomposition of organic material.
