The results of researches on the infl uence of new metal and protein compounds in the feeding of rabbits and broiler chickens on the quality of meat have been presented in the paper. The researches have been aimed at solving the urgent problem of providing the population of country with complete-fl edged diets, which today account for up to 30 % of meat products. The paper shows that a lifetime change in the chemical composition and nutritional value of muscle tissue, obtaining functional foods is possible when correcting the micromineral part of the diet of animals through the use of metal and protein complexes Belmin and Chrombelmin. The use of modern research methods allowed us to determine the optimal rate of feeding these feed additives. The results have been shown that the inclusion in the diet of rabbits organic complex Belmin in an amount of 2,0 dose per head/day has increased content in muscle tissue of rabbits of iron (+37,8 %, P < 0,001), copper (+34,66 %, P < 0,001), zinc (+27,01 %, P < 0,001) and essential amino acids (+5,1–0,53 %). Feeding Chrombelmin to broiler chickens as part of compound feed (0,15 %) has increased the level of selenium in the chest muscle by 3 times (P < 0,001), in the femoral muscle – by 1,25 times. The content of manganese, zinc, and chromium changes slightly. In the breast muscle of broilers the lipid content has been increased by 1,37 % (P < 0,05), and in the femoral muscle it decreased by 1,11 % (P < 0,05). The use of metal and protein feed additives Belmin and Chrombelmin in animal husbandry increases productivity, as well as the production of meat products with the increase of content of micronutrients, which will provide the population with not only high-quality, but also useful for health food products.

Currently, considerable interest is caused by the study of the effect of various feed additives on the productive performance of animals. The ban on the use of antibiotics to stimulate poultry growth in many European countries has increased the interest of researchers and practitioners in the use of probiotics. It is important to study the use of non-traditional feed in animal husbandry. Thus, waste processing of rapeseed (presscake, meal) is the most important sources of essential amino acids (lysine, methionine, tryptophan, etc.), essential fatty acids (linoleic, linolenic, arachidonic, oleic, etc.). The importance of rapeseed seeds and products of its processing has increased after the breeding of varieties with a low content of erucic acid and glucosinolates. The purpose of the research was to study the use of non-traditional feed and probiotics in the rearing of goslings to obtain full-fl edged products when they are grown up to 4 months of age. The possibility of replacing sunflower presscake with rapeseed presscake of Siberian selection and partial replacement of full-fat soy with rapeseed oil has been carried out. It has been found that the treatment of goslings after birth with probiotics “Prolam” and “Monosporin” and their use in feeding the goslings had a positive effect on their growth and development. With an increase in production costs and an increase in the cost of feed, the prime cost of 1 kg of live weight gain has decreased when processing and feeding probiotic “Prolam” by 17,9 %, “Monosporin” by 15,4 %. It has been obtained profits on 1 head more from the use of probiotics by 29,8 and 35 Rubles, respectively, in comparison with the control group. The level of profitability when using probiotics in the 1st experimental group has increased by 29,7 %, in the 2nd group by 24,7 %. The weight of the semi-eviscerated carcass was higher in the experimental groups receiving rapeseed presscake and rapeseed presscake in combination with rapeseed oil, and exceeded the weight of the carcasses of the control group by 286,13 and 388,48 g, respectively. The mass of eviscerated carcasses was also higher in the experimental groups.

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.

The absorption and metabolism of phytogenic feed additives in poultry is studied related to the metabolism and deposition of their main compounds in tissues intended for food production. Fifty-six non-sexed Ross 308 broilers were allocated to seven dietary treatments and fed a diet containing graded levels of thyme ( Thymus vulgaris L.) essential oil (EO) (0, 0.01, 0.02, 0.03, 0.04, 0.05, 0.1%, w/w). Thymol concentration was measured in plasma, liver, kidney and breast muscle tissue using solid phase micro-extraction followed by gas chromatography/mass spectrometry. We found the highest concentrations of thymol in kidney and plasma, and the lowest in breast muscle and liver. Thymol content in plasma and kidney significantly increased when 0.05 and 0.1%, w/w, EO and in liver and breast muscle only when 0.1%, w/w, EO was added to the diet ( p<0.05). Our results indicate intensive metabolism of thymol in liver and its accumulation in kidney tissue. We confirm low deposition of thymol in the muscle tissue. It is necessary to keep in mind the selection of a sufficient concentration of EO in the feed additive for animals without the risk of thymol residues in edible tissues.

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.

The article presents experimental data on the detection of antibiotics enrofloxacin and ciprofloxacin in poultry meat. We also analyzed the timing of removal of these antibacterial drugs from the poultry body and assessed the biological safety of products of slaughter of broiler chickens. These studies were conducted in the Syrian Arab Republic. It is established that in the free sale cases of sale of chicken meat containing enrofloxacin are detected. This is probably due to the fact that poultry is slaughtered before treatment is completed. On the contrary, such an antibacterial drug as ciprofloxacin is found in single samples and in minimal concentrations. Comparative data on the accumulation of enrofloxacin in the thoracic and femoral muscles are also provided, and maximum concentrations of this drug in the muscle tissue of broiler chickens are established. It was found that the concentration of ciprofloxacin in samples taken from all four districts is below 18 mcg/ kg, which is below the maximum allowable (100 mcg/kg). The concentration of enrofloxacin in the femoral muscle samples in the fourth district was higher than the maximum permissible limits (100 mcg/kg). In addition, the average concentration of enrofloxacin in the fourth district exceeded the maximum allowed limits without taking into account the average concentration of ciprofloxacin in the same sample. The low concentration of ciprofloxacin compared to enrofloxacin, as well as the absence of high concentrations of the former, may indicate that the bird was not treated with ciprofloxacin, but it could be a product of enrofloxacin metabolism in birds.

In Russian market of meat products production of poultry meat occupies more than 47 %. At the same time, the share of poultry products in the total volume of animal protein consumed is 42,1 %, including poultry meat – 27,8 %, eggs – 14,3 %. The quality of the resulting meat is significantly influenced by feeding (feed ingredients, biologically active additives). The purpose of the investigations was to study the influence of compound feed containing Camelina presscake on the chemical composition of broiler muscle tissue. The investigations have been carried out on the basis of the Siberian Scientific and Research Institute of Poultry Farming – a branch of the Federal State Budgetary Scientific Institution “Omsk Agricultural Research Center” (Morozovka village, Omsk region) on broiler chickens of the cross Sibiryak-2. The results of the investigations on the influence of compound feed with Camelina presscake obtained from seeds of the Siberian selection on the qualitative composition of the muscle tissue of broilers have been presented in the article. The research has been conducted on four groups of broiler chickens from 1 to 42 days of age, in each group there were 100 heads. Camelina presscake was introduced instead of another traditional protein feed to the 1st experimental group – 12,5 %, the 2nd – 15 % and the 3rd experimental group – 20 % with the preservation of the total energy and protein nutrition of the compound feed. It has been found that in the muscles of broiler chickens of the experimental groups the protein content was higher by 0,06–0,73 abs.%, fat by 0,03–0,57 abs.%, energy nutrition higher by 0,03–0,29 MJ/kg. When comparing the amount of macro- and microelements in muscle tissue, the advantage has been noted for most of the studied indicators of poultry of experimental groups that received compound feed with Camelina presscake.

The Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

Vancomycin Resistant

In recent years, antibiotic-resistant bacteria with an impact on human health, such as extended spectrum β-lactamase (ESBL)-containing Enterobacteriaceae, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE), have become more common in food. This is due to the use of antibiotics in animal husbandry, which leads to the promotion of antibiotic resistance and thus also makes food a source of such resistant bacteria. Most studies dealing with this issue usually focus on the animals or processed food products to examine the antibiotic resistant bacteria. This study investigated the intestine as another main habitat besides the skin for multiresistant bacteria. For this purpose, faeces samples were taken directly from the intestines of swine (n = 71) and broiler (n = 100) during the slaughter process and analysed. All samples were from animals fed in Austria and slaughtered in Austrian slaughterhouses for food production. The samples were examined for the presence of ESBL-producing Enterobacteriaceae, MRSA, MRCoNS and VRE. The resistance genes of the isolated bacteria were detected and sequenced by PCR. Phenotypic ESBL-producing Escherichia coli could be isolated in 10% of broiler casings (10 out of 100) and 43.6% of swine casings (31 out of 71). In line with previous studies, the results of this study showed that CTX-M-1 was the dominant ESBL produced by E. coli from swine (n = 25, 83.3%) and SHV-12 from broilers (n = 13, 81.3%). Overall, the frequency of positive samples with multidrug-resistant bacteria was lower than in most comparable studies focusing on meat products.
