Tetracycline HCl is one of the most commonly used antibiotics in animal feed additives to control disease caused by bacteria. The dosage of antibiotics added to animal feed is sometimes not in accordance with existing regulations, causing residues in the body to be left behind. The purpose of this study was to determine the presence and levels of tetracycline HCl antibiotic residues in the meat and liver of broiler chickens on farms in Lamongan City by using the spectrophotometric method by selecting the maximum wavelength which was carried out by making the absorbance relationship curve and the wavelength of the standard solution at a certain concentration. The results of tetracycline antibiotic residues in boiler chicken meat and liver on the first farm showed that the residual levels of tetracycline HCl were 3,969.10 ± 392.32 ppm and 14,247.74 ± 2,632.63 ppm, on the second farm showed residual levels of tetracycline HCl. 5,470.03 ± 512.76 ppm and 20,464.60 ± 5,985.63 ppm, respectively, and the third farm showed that the remaining levels of tetracycline HCl were 7,032.37 ± 971.99 ppm and 19,232.71 ± 6,404.63 ppm. The results showed that the residual content of tetracycline HCl in broiler meat and liver exceeds the maximum residual content of tetracycline class of antibiotics in meat and milk based on SNI 01-6366-2000 which limits the residue to not more than 0.1 ppm.

The paper presents the study on an impact of feed additives Peak anti-stress and SPAO (SPAO-complex) with different lithium content on meat productivity and meat quality of broiler chickens. The feed additives exert a pronounced metabolic effect, have adaptogen properties and allow forming a mechanism that facilitates compensation of the expenditure of the body, which significantly increases upon stress development. It was established that the average daily gain of the broiler chickens increased by 1.8% and 4.3% on the background of using SPAO-complex and Peak anti-stress, respectively, compared to the broiler chickens that did not receive the feed additives in the daily diet. It was shown that addition of feed additives with lithium into a diet led to an improvement of the indices of broiler meat productivity and meat quality: a level of yield of the carcasses of the 1st category increased up to 56.2–79.1%, high organoleptic indices of meat were ensured, the protein content in white and red chicken meat increased and functional-technological properties of minced meat improved. The use of feed additives ensured profitability of industrial poultry production; the highest indices of profitability were established upon introduction of the feed additive Peak anti-stress into a diet — up to 8.67 rubles per each ruble of expenses. The obtained results of the study should be taken into consideration in the technological processes when raising broiler chickens.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

Scientific publications describe the positive effect of feed additives and pharmacological complexes on metabolic processes in the body of broiler chickens, in particular, on the protein composition of the blood, meat productivity and protein accumulation in meat. The Peak-Antistress feed additive developed at the Department of Morphology, Physiology and Pharmacology of the South Ural State Agrarian University allows to reduce the technological load on the poultry body by stimulating the general metabolism and complex antioxidant action. Experiments on the use of the feed additive Peak-Antistress were carried out on broiler chickens of the final hybrid of the Arbor Acres cross in an industrial-type poultry farm with floor technology. The poultry was divided into three groups of 6,000 chickens each and kept in one workshop in separate sections. The control group received the main diet, the 1st experimental group received the main diet and feed additive at a dose of 1269 g / t of feed 5 days before slaughter, the 2nd experimental group received the main diet and feed additive at a dose of 1693 g / t of feed 5 days before slaughter. Slaughter of broiler chickens was carried out according to the technological instructions of the enterprise on the 38th day. Against the background of the use of the feed additive in the experimental groups of broiler chickens, stimulation of protein metabolism was observed, as evidenced by an increase in total protein in the blood by 7.9–20.1%, an increase in the level of protein in white meat by 0.1–0.3%, and a tendency to an increase in amino acids in white meat protein by 0.2–12.3%.

Abstract The article presents the results of studies conducted on the inclusion of Presan and Selko pH feed additives produced on the basis of organic acids in the feeding diets of Ross-308 cross broiler chickens. Organic acids and their salts are used in poultry farming as an alternative to feed antibiotics, and also has the ability to prevent the development of intestinal bacterial infection, increase the resistance of the body, thereby improving the absorption of feed nutrients and increasing poultry productivity. The largest preslaughter weight was in the groups of cockerels getting the T6 diet without antibiotics adding, which is 1.92% more than the groups getting the T1-control diet. In addition, the output of the pectoral and femoral muscles was higher by chickens getting a T6 diet by 0.5 and 0.3%, in contrast to groups getting a standard diet. Thus, it has been experimentally proven that the tested feed additives Presan and Selko pH do not reduce the slaughter performance of broilers.

We evaluated whether olive leaves (OLs) are effective as feed additives and supplements for ruminants and the potential methane reduction effects during in vitro fermentation. Two Hanwoo cows (460 ± 20 kg) equipped with cannula were fed Timothy hay and corn-based feed 3% of the body weight at a ratio of 6:4 (8:30 a.m. and 5:00 p.m.). Ruminal fluid from the cows was collected and mixed before morning feeding. In vitro batch fermentation was monitored after 12 and 24 h of incubation at 39 °C, and OLs were used as supplements to achieve the concentration of 5% in the basal diet. At 12 h of fermentation, methane production decreased in the 5% OLs group compared to that in the control group, but not at 24 h. The proportion of cellulose-degrading bacteria, Fibrobacter succinogenes, Ruminococcus albus, and Ruminococcus flavefaciens, tended to increase in the 5% OLs group at 12 h. The amount of ammonia produced was the same as the polymerase chain reaction result for Prevotella ruminicola. At 12 h, the proportion of Prevotella ruminicola was significantly higher in the 5% OLs group. OLs may be used incorporated with protein byproducts or other methane-reducing agents in animal feed.

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 withdrawal of antibiotic growth stimulators as of 1 January 2006 in the European Union countries has forced the search for alternative solutions to improve the health and productivity of poultry. The poultry industry also faces the challenge of developing alternative feeding systems with the restriction or exclusion of coccidiostats. One of them is the use of probiotic strains as feed additives. This study aimed to determine the effect of the use in compound feed of a probiotic containing Bacillus licheniformis on rearing rates and postmortem performance of broiler chickens. The experiment was performed on 8012 unsexed broiler chickens of the Ross 308 line divided into four equal groups. The experimental factors were the addition of a probiotic containing Bacillus licheniformis bacteria and the addition of a coccidiostat. The introduction of probiotic bacteria into compound feed did not increase the body weight of birds, in particular, control weights, and at the end of rearing, but it decreased the feed conversion rate (FCR) and mortality. Addition of probiotic in compound feed did not have a significant effect on bird muscle. The mean weight of pectoral muscle between control (C+, C–) and study (C–BL, C+C–BL) groups did not show statistically significant differences; however, the highest mean weight of the evaluated parameter was visible in the C+ group (0. 665) and the lowest in the C–BL group (0. 623). Similarly to the mean weight of the carcass, also in the mean weight of thigh muscles, the lowest statistically significant values were observed in chickens belonging to the C+C–BL group (vs. C–; P <0.05). Based on the obtained results, it can be acknowledged that the probiotic bacteria Bacillus licheniformis in broiler feed can be a good feed additive to replace antibiotics/coccidiostats. This probiotic has a positive effect on the overall health of birds, contributes to better use of nutrients and stimulates growth and development of broiler chickens.

At the moment, an important issue for medicine and veterinary sciences is the lack of iodine and selenium in human and animal bodies. The problem of I, Se, and S deficiency in livestock has not been solved yet, which motivates the development of new effective compounds of these elements. Particularly noteworthy are the citrates of minor nutrient elements included in mineral premixes and feed additives used to balance mineral nutrition in the diets of animals and poultry. The purpose of this paper is to study the efficacy of different doses of I, Se, S citrate on the intensity of metabolic processes in the body of chicken broilers before and after the intragastric introduction of E. coli. It was found that watering of chicken broilers with I, Se, S citrate has antibacterial action. As a result of the conducted studies, it was revealed that the applied doses of I, Se, S caused both prophylactic (E2) and therapeutic (E4) effect on the development of colibacillosis in broiler chickens. This effect is more pronounced with higher doses of Iodine (20 μg/dm3) in I, Se, S citrate for therapeutic purposes, which contributed to the 100% preservation of the chicken population. High metabolic activity of low doses of I, Se, S citrate with a content of 2.5 μg I dm3 was noted. It provided the highest weight gain of chickens and reaching 780 g on the 35th day of growing, or 121.5% versus control and 788.4 g (119.9% versus control) on 42nd day of growing in the vivarium. The obtained data indicate a positive influence of watering I, Se, S citrate with a content of 20 μg I/dm3, which was characterised by 100% preservation of chickens throughout the growing period

This research has been carried out to determine the effects of the current misinformation (hormone, antibiotic, feed additives and growth of broiler chickens in a short period) on consumers' view of the poultry meat sector. The survey was conducted in Istanbul province which better reflects the socio-cultural and socio-economic structure of Turkey, and with different demographic structure of 384 people face to face survey method was applied. Questions were asked to determine whether antibiotics and hormones were used in the diet of broiler chickens, and consumers' perceptions, attitudes and behaviors about the reliability of chicken meat. According to the results of the study, 73.4% of the consumers stated that they did not know about the contents of broiler diets. A big majority of the consumers (88.3%) stated that they think hormone is used and 84.6% think antibiotics is used in the feeding of broiler chickens. 78.4% of consumers surveyed stated that they think that broiler chickens are not fed with healthy feed. Also, 70.6% of consumers stated that rapid growth was due to use of antibiotics and hormones. Although the use of hormones and antibiotics as growth promoters in poultry feeds is prohibited, consumers think that they are used as additives and broiler meat is not safe food. According to these results, creating a positive effect on the purchasing decisions of the consumers is important for the sustainability and future of the sector.

This study aims to examine the effect of adding nucleotides in broiler rations on the protein mass and calcium mass of broiler chicken reared at different temperatures. The material used was 135 broiler chickens aged 15 days with a weight of 462.20 ± 9 grams of unsex Ross strain and nucleotides imported from China produced by CBH Co. Ltd., China. The study used a completely randomized design (CRD) with a 3x3 factorial pattern with 5 replications. The treatment was carried out at the age of 15-35 days. The treatment given was the first factor adding nucleotides (T0 = nucleotides 0 g/kg feed, T1 = nucleotides 0.5 g/kg feed, T2 = nucleotides 1 g/kg feed) and the second factor was temperature (Heat = S1 = 30 – 32?, Comfortable = S2 = 20 – 23?, Natural = S3 = 24 – 34?). Parameters observed were protein content, calcium content, protein mass, and calcium mass of broiler chicken meat. The research data were analyzed using the F test of variance analysis, if there was a real treatment effect, then Duncan's test was continued. The results showed that there was no interaction between the addition of nucleotides with different maintenance temperatures on protein content, calcium content, protein mass, and calcium mass of meat. Nucleotide 0.05 g had a significant effect (P<0.05) on the protein content of the meat, the natural rearing temperature significantly affected the calcium content of the meat and the comfortable temperature had a significant effect on the protein mass of broiler meat. This study concludes that the addition of 0.05 g of nucleotides can meet the needs of nucleotide synthesis in the body of broiler chickens by increasing the protein content of the meat.
