Science and practice have proved that balanced nutrition involves the intake of the organic, mineral, and biologically active substances in the bird’s body in certain quantities and proportions due to their needs. Balanced poultry feeding is a guarantee of not only high productivity, but also the prevention of diseases that negatively affect the safety of livestock and product quality. Providing poultry with high-quality protein is especially important nowadays. Birds spend more essential amino acids per unit of body weight gain and, accordingly, more of them should be daily supplied to the body with feed. Plant proteins are the basis of grain feeds that contain all eleven essential amino acids required for protein synthesis in the body of chickens, ducks, geese, and turkeys. However, it was revealed that most of these amino acids are concentrated in grain in insufficient quantities and cannot fully satisfy the needs of highly productive poultry. As a result, it is necessary to additionally introduce high-protein supplements into the diet as a source of essential amino acids or use synthetic concentrates of lysine, methionine, threonine, and tryptophan. High-protein supplements are coming in two types – animal and plant-based. From the plant-based ones, soy products are considered the most valuable as a concentrated source of the first limiting amino acid - lysine, and sunflower meal is rich in methionine. And even so, plant-based protein feed is not able to create a complete balance of all essential amino acids. This can be done only if the animal-sourced protein is introduced into the poultry diet in the form of fish meal, meat and bone meal, meat meal, or yeast. Besides, scientific research has proven that yeast can be considered a wonderful natural source of B vitamins. The analysis of scientific research indicates that today there is a wide search and study of various feed supplements that could be a source of complete protein and have in its composition a complete complex of amino acids for birds. There are not enough such high-quality feed additives in Ukraine, and those coming from abroad are distinguished by high cost and are often falsified. Therefore, the use of yeast in poultry diets as long as their industrial production according to the technology based on the state standard is relevant for solving a number of modern poultry farming problems and is of great scientific and practical importance.

Effective Level

Amino acids are the basic structural units of protein molecules in the body. Currently, about 300 amino acids are known, of which 26 are studied best. Amino acids or their derivatives (for example, immune bodies) are part of enzymes, hormones, pigments, and other specific substances that play a crucial role in digestive and metabolic processes. In the process of metabolism, many amino acids are synthesized in the body from other amino acids or compounds, and therefore they are called interchangeable. Amino acids that are not synthesized in the body or are formed in insufficient quantities are called indispensable. According to the content and ratio of essential amino acids, feed proteins are subdivided into full and inferior. Deficiency, absence, or imbalance of essential amino acids in animal diets is accompanied by a deterioration in protein use, metabolic disorders, and decreased productivity. The following amino acids are indispensable; arginine, viburnum, histidine, isoleucine, leucine, lysine, methionine, threonine, tryptophan, phenylalanine. Among the essential amino acids, especially important ones, are those called critical. These are lysine, methionine + cystia, threonine, and tryptophan. A deficiency, absence, or imbalance of essential amino acids in animal diets is accompanied by a deterioration in protein use, metabolic disorders, and decreased productivity. Research and production experiment was conducted within Olenka Poultry Factory LLC and the problematic research laboratory of feed additives of the Department of Animal Feeding and Feed Technology named after P. D. Pshenichny at the National University of Life and Environmental Sciences. The effective level of arginine in compound feed for broilers of the Cobb-500 cross was experimentally determined. The use of compound feed with arginine levels in the first rearing period (1 to 10 days) - 1.28%, in the second (11 to 22 days) - 1.15% and in the third (23 to 42 days) - 1.11% gives the opportunity to get broiler chickens at the age of 42 days, weighing 2.654 kg, at a feed expenditure of 1.78 kg per 1 kg of gain.

Many researchers note the need to improve feed additives and the search for new promising drugs for the intensification of the pig industry. We have developed a biologically active complex drug Microlact. It is used by animals as a means aimed at correcting the disturbed metabolism of sows associated with pregnancy and lactation, to activate the growth and development of piglets as well as their viability. The purpose of the work was to develop and study the effectiveness of the biologically active drug in the diet of lactating sows. The use of the drug led to the improvement of biochemical parameters of blood of pregnant sows, indicating the activation of metabolic processes in their body, which provided the increase in milk yield of sows, average daily weight gain of piglets and their livability. The live weight of piglets for weaning increased by 8,0% (P < 0,01), the livability of suckling piglets increased to 93,1%, which is a consequence of improving the quality of colostrum and milk, and consequently the positive effect of the biologically active drug containing an optimal complex of minerals, vitamin E in the composition of malt sprouts, essential amino acids and organic form of selenium. More nutritious colostrum and milk contributed to the better development of the piglets’ body and resistance to adverse factors. Immunoglobulins have been obtained by piglets with colostrum and milk increase their resistance and contribute to higher livability. The increase in the weight of suckling pigs has a positive effect on the further development and growth of animals on fattening. Thus, the administration of the biologically active drug Microlact to sows during pregnancy leads to the activation of metabolic processes, which can only be provided by a high level of functioning of the organs and systems of the body.

Aim. Study of the effect of new domestic lactulose-containing feed additives on the biological properties and amino acid composition of the protein in broiler chicken meat. Material and Methods. During the research, classical and modern methods were used: zootechnical, biochemical, etc. The methodological basis was the scientific works of domestic and foreign scientists who studied the features of the effect of feed additives on the body of poultry and its productive qualities. The mass fraction of protein was determined by the Kjeldahl method according to GOST 25011-2015, the mass fraction of fat – by the Extractive-weight method according to GOST 23042-2015, the mass fraction of moisture – by the thermogravimetric method using the ELVIZ moisture analyzer, the mass fraction of total ash – GOST 31727-2012 (ISO 936:1998), amino acid composition of pectoral muscles – by capillary electrophoresis (Kapel 105M). Results. As a result of the experiment, it was found that the use of additives No. 1 and No. 2 helps to stabilize the indices of digestibility of nutrients and, as a result, to improve the metabolic process in the body of the bird. It was found that the digestibility coefficient of dry matter in the experimental groups was by 0.91%, crude protein – by 1.68%, crude fat – by 0.79%, nitrogen-free extractable substances – by 1.33% higher than in the control group. Positive dynamics was also noted in the increase in the weight of the gutted carcass in the experimental groups by 5.47 and 4.46% in comparison with the same indicator in the control group. The use of lactulose-containing additives when growing broilers has led to an improvement in the quantitative and qualitative characteristics of the resulting product ("white" meat). An increase is observed in the value of the mass fraction of protein by 0.5 and 0.6%, respectively, in comparison with the mass fraction of protein in the meat of the control group. The studied feed additives balanced the ratio of essential amino acids to replaceable ones. During the experiment, it was found that in the white meat of the experimental groups, in comparison with the white meat of the control group of broiler chickens, there was an increase in the content of essential amino acids on average by 0.31 г/100 г (3.6%) и 0.41 г/100 г (4.7%), respectively. Conclusion. In terms of a set of indicators, the meat of broiler chickens grown with the use of new lactulose-containing additives No. 1 and No. 2 has higher indicators of meat quality compared to the control. New domestic prebiotic supplements based on lactulose No. 1 and No. 2, used in the experiment, are not only a natural alternative to antibiotics, hormones or other growth stimulants, but also a mechanism for a better approach to the formation of general beneficial physical and biochemical properties of meat of broiler chickens. Given this, these additives can be recommended for widespread implementation in poultry farming.

One of the conditions for obtaining high-quality pig products is the use of feed additives, which contain all the necessary biologically active substances, eliminating their deficiency in feed and acting as catalysts for metabolic processes in pigs. That is why the aim of the study was to study the effect of feed additive “Sylimevit” on the enzymatic and non-enzymatic parts of the antioxidant system of piglets after weaning. Two groups of piglets were formed – control and experimental, in the amount of 10 individuals in each group, selected on the principle of analogues – age, breed and body weight. During the weaning period, the piglets were kept under the sow in special machines, had constant access to the mother, and from the age of 5 days – free access to concentrated feed. Feeding of animals was carried out in accordance with the norms for a given age of pigs. Prior to the study, a clinical and physiological examination of the piglets was performed. Their general condition and activity when eating food were taken into account. On the 28th day of life, the piglets were weaned from the sow and regrouped from different nests in order to be further maintained during the period of fattening and rearing with a change in the structure of the diet, which served as technological stress for the animals. From the age of 5 days, piglets of all groups were fed pre-starter feed. Piglets of the experimental group, from 21 to 40 days of age, were additionally fed the feed supplement “Sylimevit” at a dose of 100 mg/kg body weight per day. Feeding piglets Silimevit feed enhances their antioxidant status. The use of this feed additive in piglets contributed to the activation of both enzymatic and non-enzymatic parts of the antioxidant defense system of piglets after weaning, as indicated by an increase in blood 35-day-old piglets superoxide dismutase activity by 26.9 % (P < 0.001), catalase – 41.1 % (P < 0.001), glutathione peroxidase – by 52.7 % (P < 0.05), glutathione reductase – by 53.5 % (P < 0.05), the content of reduced glutathione – by 75 % (P < 0.001). This is due to the fact that silimevit contains active substances such as milk thistle and vitamins, which are strong direct-acting antioxidants and directly interact with free radicals and reactive oxygen species.

Unbalanced mineral and vitamin nutrition of lactating cows can be a critical factor in the realization of their productive potential. The development and introduction into production of inexpensive, but effective feed additives is the main trend of improving the feeding of modern animal husbandry. Under the conditions of the Tyumen region such natural raw materials can be sapropels, which successfully combine a variety of biologically active substances. The purpose of the research was to study the digestibility of nutrients and energy metabolism in lactating cows when sapropel is included in the ration. Scientifi c and economic experiment in the study of the effectiveness of feeding sapropel lake Nepryak has been carried out in the training and experimental farm of the State Northern Trans-Urals Agrarian University. The animals of the control group have been fed the main diet. Cows of the 1st and 2nd experimental groups have been fed 300 and 500 g of sapropel per head/day, respectively, in addition to the main ration. It has been found as a result of research that the introduction of sapropel into the ration of cows has a positive effect on the digestibility of nutrients. The digestibility coefficients were higher in the animals of the 1st and 2nd experimental groups compared with the cows of the control group. Cows from the experimental groups digested all the organic substances of the ration better. During the experiment period cows of the 1st and 2nd experimental groups in contrast to the control group had higher milk yield by 11,31 and 10,38 %, respectively, milk protein yield by 10,56 and 5,95 %, milk fat yield by 17,18 and 12,99 %. It has been established that the introduction of sapropel into the ration of cows has the positive effect on the digestibility of nutrients, contributes to the increase of milk productivity, normalizes the metabolism in the body.

High protein wheat was the sole cereal in 20 and 25 per cent crude protein broiler starter diets. On the. 25 per cent protein diet, performance was maximized without amino acid supplementation. Using high protein wheat in 20 per cent protein diets, growth rate was improved by l-lysine supplementation of 0.3 per cent. However, this growth rate was not at a maximum level. Some other dietary factor was necessary, and this did not appear to be essential amino acids, singly or in combination.
