The materials on the study of the feed additive Abiotonic in rabbit breeding, as well as the results of organoleptic, microbiological, histological studies and the amino acid composition of rabbit meat of the New Zealand white breed are presented. According to the results of the studies, there was no negative effect of the feed additive on the veterinary and sanitary indicators of rabbit meat, the carcasses were well bled, drying crusts were formed in a timely manner, the muscles were elastic, light pink, white fat, the broth was clear and aromatic. No pathogenic and conditionally pathogenic microflora were found. At the same time, it was noted that the feed additive contributed to the increase in meat of non-essential amino acids by 6,01%, essential amino acids by 9,74%, which increases the biological value of the product. According to histomorphological studies, the Abiotonic feed supplement did not adversely affect the physiological state of animals, muscle tissue and internal organs developed within the physiological norm of rabbits.

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.

Reduced activation of energy metabolism increases adiposity in humans and other mammals. Thus, exploring dietary and molecular mechanisms able to improve energy metabolism is of paramount medical importance, as such mechanisms can be leveraged as a therapy for obesity and related disorders. Here, <a>we show that a designer protein-deprived diet enriched in free essential amino acids can i) promote the brown fat thermogenic program and fatty acid oxidation, ii) stimulate uncoupling protein 1 (UCP1)-independent respiration in subcutaneous white fat, iii) change the gut microbiota composition, and iv) prevent and reverse obesity and dysregulated glucose homeostasis in multiple mouse models, prolonging the healthy lifespan. </a>These effects are independent of unbalanced amino acid ratio, energy consumption, and intestinal calorie absorption. A brown fat-specific activation of the mechanistic target of rapamycin complex 1 seems involved in the diet-induced beneficial effects, as also strengthened by <i>in vitro</i> experiments. Hence, our results suggest that brown and white fat may be targets of specific amino acids to control UCP1-dependent and -independent thermogenesis, thereby contributing to the improvement of metabolic health.

The research has proved that the usage of probiotyk in feeding of broiler chicken facilitate increasing of the digestibility of amino acids including irreplaceable. Revealed that the digestibility of amino acids was highest in broilers consumption average dose supplements investigated. It should be noted that the increased digestibility of the essential probiotic amino acids, such as: lysine, histidine, arginine, valine, methionine, isoleucine, leucine. Thus, the use of probiotic supplements improve the usefulness of protein supply. Such positive changes result in the increasing of broiler efficiency. The research has proved that the usage of different doses of probiotic supplements «Entero-active» has positively effects on amino acid content in meat of broiler chickens. Specifically, the thoracic and femoral muscles of poultry raised the level of most essential amino acids. Thus, consumption of probiotic feed broilers improves meat quality.

Today feeding disorders (deficiency of crude protein and limiting amino acids), the use of feed contaminated with microscopic fungi can lead to immune depression. When feeding dysfunctional feed, the live weight gain of young animals and fattening pigs is reduced by 10-90%, depending on the balance and completeness of the rations in terms of nutrients. The article assesses the degree of contamination of feed with microscopic fungi and studies the effect of eliminating the deficiency of crude protein, lysine and methionine on the health status and weight gain of laboratory rats when feeding moldy wheat grain. A balanced for essential amino acids feed allows reducing the stress of the body's defense system from the negative effects of saprophytes. An experiment was carried out on 200 (10 groups, n = 20) weaned rats of the Wistar line in order to comparatively study the consequences of feeding the diets containing wheat grain contaminated with fungi of the genera Aspergillus and Penicillium, deficient and balanced to the norms of the requirement for crude protein and two essential amino acids - lysine and methionine. The number of micromycete reaches 109 CFU (spores) in 1 gram of feed. These molds are dangerous because of the possibility of their spores entering the body of animals and germinating in the lungs, liver, kidneys, heart, intestines, reproductive organs, and muscle tissue. Once in the blood, mold spores spread throughout the body. A complete zootechnical analysis of grain was carried out in the toxicology laboratory using the methods of zootechnical and biochemical analyzes of feed, livestock products and metabolic products. The negative effect of microscopic fungi on the health indicators of white rats is less pronounced with a balanced diet for essential amino acids. A decrease in the tension of immunity, expressed in a decrease in T-cell deficiency and activation of phagocytosis, was determined. The average daily gain on the contaminated feed decreased by no more than 20%, while the gain on the contaminated diet was 50-60% lower.

1. In hay-fed, cannulated sheep the apparent degradation in and outflow from the rumen were determined for graded doses of mixtures of the amino acids lysine, threonine and methionine, administered intraruminally and using polyethylene glycol (PEG) as a liquid marker. The doses ranged between 2.5 and 15 g for each amino acid in the mixtures.2. Relative rate of apparent degradation in the first 4 h was highest for lysine, and lowest for methionine. The apparent degradation in 24 h was highest for lysine and lowest for threonine. Conversely the fraction flowing out of the rumen in intact form in 24 h was highest for threonine and lowest for lysine. Rates of apparent degradation as well as outflow were dose-dependent.3. The validity of the estimated outflow of amino acids from the rumen was corroborated by measurements of concentrations of the amino acids in duodenal contents and in blood plasma which were also dose-dependent.4. It was concluded that part of the requirement for the essential amino acids threonine and methionine may be met, even when these amino acids are delivered in unprotected form, given as a feed supplement.

The article summarizes, in a concise form, information about the importance of amino acids in the context of solving the problem of fodder protein deficiency. Amino acids, as structural components of proteins, are central to the exchange of nitrogen-containing compounds and are vital for life processes. Essential amino acids are not synthesized by the body of animals and humans, but are prepared as a part of diets. Vegetable proteins are less complete than animal proteins due to the absence of some essential amino acids. Therefore, in feeding, plant feeds are balanced by limiting amino acids, which are obtained by chemical or microbiological synthesis, or combine protein sources, taking into account their amino acid composition. Amino acids are the primary microbial metabolites that are synthesized by microorganisms in the process of life. Due to the large-scale cultivation of microorganisms in industrial conditions, amino acids, proteins, preparations for increasing the productivity of crops and animals are receive. Appropriate types of microorganisms use ammonia oxidation energy to synthesize their own organic matter. Different bacteria for the synthesis of amino acids also use nitrogen, nitrates, urea. The microbiological synthesis and accumulation of metabolites in the substrate depends on the component composition, temperature. Microbial growth is usually limited by the nutrient component. Sulfur deficiency limits the utilization of nitrogen by microorganisms. The introduction of sulfur compounds into the environment stimulates microbial synthesis in general, including sulfur-containing amino acids. As a result of incubation of the biosubstrate for 3 days at a temperature of 18 °C, the synthesis of most amino acids by microbial association was activated. Incubation with sodium sulfate (at a dose of 0.3% by weight of biosubstrate) for 3 days at 25 °C had the best stimulating effect on amino acid biosynthesis. Such a biosubstrate can be used as a source of amino acids in the form of a fertilizer or feed additive. In the XXI century anthropogenic impact causes an imbalance of the ecological situation, one of the manifestations of which is the reduction of soil fertility, which can be restored by the introduction of mineral and organic fertilizers, as well as preparations containing amino acids and stimulate seed germination, increase the yield, fertility, and fertility. Amino acids are used as additives in food production, in the treatment of diseases of different etiologies and for other purposes.

This study evaluated the effectiveness of a 4-week intervention of melatonin and essential aminoacid supplementation on body composition, protein metabolism, strength and inflammation in 159 elderly sarcopenic patients (42/117, men/women), assigned to four groups: isocaloric placebo (P, n = 44), melatonin (M, 1 mg/daily, n = 42), essential amino acids (eAA 4 g/daily, n = 40) or eAA plus melatonin (eAAM, 4 g eAA and 1 mg melatonin/daily, n = 30). Data from body composition (dual X-ray absortiometry (DXA)), strength (handgrip test) and biochemical parameters for the assessment of protein metabolism (albumin) and inflammation (CRP) were collected at baseline and after the 4-week intervention. Compared with P and M, supplementation with eAA plus M increased total fat-free mass (vs. P: +2190 g; p < 0.01; vs. M: +2107 g; p < 0.05). M alone lowered albumin levels (vs. P: −0.39 g; p < 0.01; vs. eAA: −0.47 g; p < 0.01). This data on albumin was confirmed by within-group analysis (M −0.44g; p < 0.001; eAAM: −0.34 p < 0.05). M and eAA seemed to lower the percentage of gynoid fat (p < 0.05) and android fat (p < 0.01). No significant changes in inflammation or strength were reported. A 4-week intervention with eAA plus M together may be effective in enhancing fat-free-mass compared to M and P but not versus eAA. M alone demonstrates a negative effect on albumin level.

The meat of the African sharptooth catfish has a variability in indicators of nutritional and biological value, depending on the physiological state of fish. The aim of the study was to compare the nutritional and biological value of african sharptooth catfish meat during the spawning and inter-spawning period. The object of the study is muscle tissue of the african sharptooth catfish at the age of 12 months. The assessment of organoleptic properties and indicators of nutritional and biological value of the muscle tissue of the african sharptooth catfish during the spawning and inter-spawning period was carried out. The organoleptic properties of the african sharptooth catfish during the inter-spawning and spawning periods did not differ significantly. It was found that the criteria for the nutritional value of african sharptooth catfish meat in the inter-spawning period significantly exceed similar indicators during the spawning period. The meat of the african sharptooth catfish in inter-spawning period includes more fat and protein, therefore, is characterized by less water content. The biological value of meat is determined by the content of amino acids in it. During the inter-spawning period, the amount of all amino acids in the meat of African clarias significantly increases. The dominant position of essential amino acids is occupied by lysine and tryptophan. This is of exceptional importance for a living organism. Tryptophan is indispensable in the synthesis of vitamin B3, which has a vasoprotective effect, reduces cholesterol and provides prevention of hypoxia of cells and tissues. Lysine is a source of carnitine, stimulates mitosis, provides prophylaxis of osteoporosis, and stimulates bone regeneration. According to research, lysine can prevent the development and ease the course of Alzheimer’s disease. Eating foods with high levels of tryptophan and lysine ultimately improves the quality of life. The high content of lysine and tryptophan makes it possible to attribute african sharptooth meat to an indispensable component of children’s and sports nutrition.

The article presents data on a scientific experiment conducted on quails of the Japanese breed. Data on the influence of the prebiotic drug «BioAxel» on the physiological parameters of quails have been established. The dynamics of the live weight of quails when feeding different dosages of the drug is estimated. In the experiment, the positive effect of different doses of the feed additive «BioAxel» on the average daily and gross growth of experimental birds (by 8,2–16,5% compared to the control) was established. The most effective method was feeding part of the BioAxel (5% of the feed weight) plus another part (4%) with water. A comprehensive veterinary and sanitary examination of quail slaughter products was also carried out when using the prebiotic drug «BioAxel»in the diet. It was found that this drug does not have a negative effect on the quality of meat. At the same time, the indicators of biological safety are within the limits of the norm established by current regulatory documents. In terms of nutritional value, the meat of quails raised with the use of the prebiotic drug «BioAxel» exceeds the meat of quails from the control group. The content of essential amino acids significantly increased in poultry meat of the experimental groups, and the total biological value in the test with Tetrahymena pyriformis exceeded the control parameters.
