In order to increase the meat productivity of poultry scientists around the all world are working to improve the breeding traits and technologies of housing and feeding. However, the efficiency of poultry meat production on an industrial basis depends not only on the strengthening and inheritance of breed qualities, but also on a complete and balanced feeding, including the use of new feed additives. All this generally affects the duration of rearing, the average daily and absolute live weight gains, the biological value and nutritional value of poultry meat produced in industrial conditions. The purpose of the work was to study the effect of the amino acid complex and silicon dioxide on the productivity and quality of broiler chicken meat. The paper scientifi cally substantiates and experimentally proves the effectiveness of using a rational dose of ultrafine silicon dioxide (300 mg/kg of feed) and the complex of amino acids (arginine – 7 g/kg, lysine – 6 g/kg, methionine – 2 g/kg) in the rearing of broiler chickens. Data on the positive influence of the studied factor on the consumption, digestibility and use of feed nutrients, as well as meat productivity and quality of broiler chicken meat have been obtained. The dependence of meat productivity and quality of chicken meat on physiological and biochemical parameters has been proved. Analysis of the results of the production experiment has been shown that the livability of poultry in the experimental group was higher than the control group by 1,4 %. This made it possible to reduce feed consumption to 100 g/head, and feed consumption per 1 kg of chicken growth in the experimental group by 9,2 %. Activation of metabolic processes of the body of broiler chickens of the experimental group contributed to the increase in their live weight, which increased the weight of the gutted carcass, the yield of meat by 13,8 %, and meat with off al for sale by 18,0 %. The efficiency of the complex application of amino acids and silicon dioxide in the production of poultry meat is economically justified.

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.

In a greenhouse pot experiment with kohlrabi, variety Luna, we explored the joint effect of N (0.6 g N per pot = 6 kg of soil) and S in the soil (25-35-45 mg kg-1 of S) on yields, on N, S and NO3- content in tubers and leaves, and on alterations in the amino acids concentration in the tubers. S fertilisation had no effect on tuber yields. The ranges of N content in tubers and leaves were narrow (between 1.42-1.48 % N and 1.21-1.35 % N, respectively) and the effect of S fertilisation was insignificant. S concentration in the tubers ranged between 0.59 and 0.64 % S. S fertilisation had a more pronounced effect on the S concentration in leaf tissues where it increased from 0.50 to 0.58 or to 0.76 % S under the applied dose. The NO3- content was higher in tubers than in leaves. Increasing the S level in the soil significantly reduced NO3- concentrations in the tubers by 42.2-53.6 % and in the leaves by 8.8-21.7 %. Increasing the S content in the soil reduced the concentration of cysteine + methionine by 16-28 %. The values of valine, tyrosine, aspartic acid and serine were constant. In the S0, S1, and S2 treatments the levels of threonine, isoleucine, leucine, arginine, the sum of essential amino acids and alanine decreased from 37 to 9 %. The histidine concentration increased with increasing S fertilisation. S fertilisation of kohlrabi can be recommended to stabilize the yield and reduce the undesirable NO3- contained in the parts used for consumption.

Balanced addition of essential amino acids, vitamins and minerals, easily digestible proteins, namely proteins of animal origin is an important factor for efficient feeding and pigs performance, that leads to a systematic search for new solutions when using feed additives. They provide digestibility, better absorbtion of protein, vitamins, minerals and other nutrients. Such supplements include blood plasma, meat and bone meal, fish meal and others. Besides fishmeal, other protein groups are dangerous in relation to African swine fever. Furthermore blood plasma additionally to the protein group contains immunoglobulins that can passively affect the immune system of piglets, An alternative to blood plasma is the animal nutrition supplement Globigen Jump Start, which is made from chicken eggs, containing essential and replaceable amino acids with a high percentage of absorption. Another important factor is the presence of specific IgY immuno-globulins, which being ingested have a negative effect on the pathogenic intestinal microflora, namely viruses, bacteria and cryptosporidium. Knowledge of the feed additive Globigen Jump Start effect gave impetus to the study of its effect on the piglets’ performance during the stressful period after weaning. The objective of the work was evaluation of the effect of the Globigen Jump Start fed within the pre-starter feed on the productive characteristics of post-weaning piglets. Based on the obtained research results, the best ones were shown in the experimental group, which was fed compound feed containing Globigen Jump Start in the amount of 2 kg / t of compound feed. It was found that at the end of the experiment, the weight of piglets in the control group was 19.2 kg, and in the experimental group - 21.0 kg, which is 1.8 kg or 9.4% more comparing to the control.

Protein quality is determined by the type and concentration of the essential amino acids and by their bioavailability. Hence, the content of dietary essential amino acids from a protein or mixture of proteins is a factor which determines the feeding quality of the protein. The purpose of the study was to evaluate the quality of the protein from a high protein raw ingredient (corn gluten) using a chromatographic method (HPLC) under optimized experimental conditions. In this study, we used pre-column derivatization, separation by high-performance liquid chromatography (HPLC) and UV detection. The optimized method was used to determine the amino acids from high-protein raw ingredients commonly used in animal feeding (corn gluten, 61%CP). A set of 6 amino acids analyses has been performed in 6 different days, each sample being prepared in double. For characterization of data strings we used quality parameters: average, standard deviation, standard error, confidence level, precision, accuracy. For verifying the Gaussian shape of the strings we used the Kernel Density. For identifying and rejecting the outliers from the data strings we used the Q test. The very low values of the accuracy for several amino acids (glutamic acid, threonine, alanine, valine, phenylalanine, isoleucine, leucine) determined us to introduce the dilution stage (1:2) for the hydrolysed samples. The method can be considered as repeatable (precision in different days) and accurate (evaluation by tracing yields) for all the determined amino acids.
