The uncontrolled use of antibacterial drugs resulted in a wide spread of forms of microorganisms resistant to them. The resistance of most bacteria to one degree or another is observed in relation to almost all existing antibiotics, which led to a significant decrease in the effectiveness of their use not only in veterinary medicine but also in medicine. Therefore, an important task which veterinary service faces is the use of alternative antibacterial drugs. Thus, the development and use of prebiotics in the food of poultry for complete or partial replacement of antibiotics is considered as a new direction of modern scientific research. The authors were the first who studied the effect of the heteropolysaccharides “raspol” and “vetelac” on the organism of broiler chickens. A high pharmacological effect of both drugs was established with a clear advantage of raspol, the use of which, against the background of the absence of antibiotics, had a positive effect on the growth and viability of poultry and caused an increase in the natural resistance of organisms. Thus, prebiotic raspol can be used as an alternative to antibacterial agents in broiler poultry farming. This drug is recommended for the give to broiler chickens with water at the rate of 0.6 g / kg of body weight starting from 7 days of age for 10 days.

Positive Effect

With the wrong use of antibiotics for agricultural poultry, the effectiveness of their effect on the body is noticeably reduced, since pathogenic and conditionally pathogenic microorganisms become resistant to them for a certain time, i.e., there is a process of “addiction“. Experience shows that enrichment of feed rations with enzyme preparations and vitamins improves the functioning of the stomach and intestines, increases the natural resistance of the body, as a result of which the mortality of poultry decreases, the absorption of feed is significantly increased and their costs per unit of production are reduced. We studied the effect of the new vitamin-enzyme complex Vitaferm on the organism of broilers against the background of the exclusion of antibacterial drugs from the antiepizootic measures scheme and compared its effect with the enzyme preparation Avizim 110. The studies carried out indicate the positive effect of Vitafarm and Avizim 110 on the poultry organism, which is manifested by an increase in average daily poultry gains, an increase in safety, and a decrease in feed costs per unit of production. These changes can be explained by the normalization of the gastrointestinal tract of broiler chickens and increased immunity. Antibiotics suppress the body’s immune system; upset the balance of the intestinal microflora. For the complete or partial exclusion of antibacterial drugs from the scheme of antiepizootic measures, it is proposed to apply to broiler chickens with feed the vitamin-enzyme complex of Vitaferm at the rate of 15.0 g / kg starting from day old for 10 days.

The maximum number of products at the lowest cost – is the main thing, what modern poultry industry can be characterized. One of the most pressing problems at the moment is early antibiotic therapy and the associated safety of young poultry early age. In this regard, of particular interest for this study is how the most widely used antibacterial drugs effects on the one of key organs of the immune system – thymus. The article presents the data obtained in the course of the experiment, which determines how preventive treatment schemes, that includes usage single and multiple antibacterial drugs, influenced on the morphological status of the chickens thymus. We selected scheme and a combination of antibacterial drugs have not been studied previously. That was compared with the usage of probiotic Bolmol at the same treatment scheme. A comparison of morpho-functional state of the thymus of chickens 15-, 22- and 41-days-old, when applying several treatments schemes. The schemes of treatment included: the usage of one or two antibiotics during the cycle, compared with the usage of probiotic. We made the conclusions about the absence of the negative impact of selected drugs on the morphofunctional state of the thymus and the positive effect of probiotic «Bolmol». The morphometric parameters of the cortex and medulla in the lobules of the thymus of chicks 15-day-old, taking as an antibacterial drug probiotic Bolmol, were not significantly different from control values and were statistically significant when compared with chicks who used antibiotics: the width of the cortical area was on 15% and 29.09% wider then chickens receiving antibiotic treatment. This indicates a positive effect of probiotic Bolmol compared with antibacterial agents which were chosen. Thus, these data demonstrate that the use of probiotics in cyclic schemes of antibiotic prophylaxis contribute to the normal development of the thymus, which in turn leads to increased resistance and preservation of poultry. Was given the substantiation about safely usage of cyclic schemes of antibacterial drugs in the event of objective necessity.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Trace elements in the body of the bird are in small quantities, but their role in productivity remains important. In order to get a quality carcass at the slaughterhouse, you need a constant supply of nutrients and, last but not least, microelements. Zinc and Manganese are essential trace elements that affect the growth and development of birds. And their deficiency in the body has a negative effect on the productivity of birds. In the diet of broilers trace elements are mainly added with a premix in the form of inorganic salts (sulfates, carbonates). However, these micronutrient compounds in the body of the bird are insufficiently absorbed, and increasing the dose of their introduction can cause toxicosis. Therefore, in order to prevent microelementosis, it is more appropriate to use organic compounds (chelates), which have a much higher level of bioavailability and less release into the environment. This review article describes the prophylactic efficacy of Zinc and Manganese chelates in micronutrient deficiencies in broiler chickens and laying hens. With a deficiency of a particular trace element develop metabolic disorders and other pathologies (perosis, etc.). Based on the presented data, it can be concluded that the use of organic forms of trace elements in poultry feeding is a better alternative to inorganic sources, as they can be used in smaller quantities. But due to their greater bioavailability, they are better absorbed, which has a positive effect on the productivity of broilers. Since knowledge about the use of chelated forms of trace elements in comparison with inorganic forms (salts, sulfates, etc.) in the diet of poultry is still poorly understood, it is necessary to further conduct research to prevent micronutrient deficiencies in these compounds.

In realization of the genetic productivity potential of different species of farm animals, an important place is given to full feeding. Insufficient supply of farm animals with individual vitamins has negative impact on the activity of the relevant enzyme systems, hormonal status, metabolism of nutrients, the state of the natural resistance of the various organs and organ systems, the processes of adaptation and productivity level.Numerical searches have shown that farm animals need in different vitamins depends on the type, age, sex, physiological state, the season, the level of productivity and others. According to some reports ruminants have been providing with water–soluble B vitamins by their rumen microbial synthesis accordingly it was recommended to rations setting for cattle, sheep and goats, along with nutrients and minerals only by carotene and vitamins D and E .Studies have shown that the addition to the diet of calves for fattening complex of B vitamins (В1, В2, В5, В6, В10, В12) in different doses generally positive effect on bactericidal, lisocim and complement activity of blood serum, immunoglobulin cell in bull fattening.Studies have shown that the addition to the diet of bull fattening balanced in nutrients and minerals and fat–soluble vitamins A, D, E complex of B vitamins (В1, В2, В5, В6, В10, В12) in appropriate doses generally positive effect on humoral immunity state, major changes are complement activity of blood serum, depends on the dose additionally entered the diet fattening bulls B vitamins.The biggest change on humoral immunity state of calves for fattening derived from animals 3rd D (B1 – 0.040; B2 – 0.06; B5 – 1.2; B6 – 0.25, B10 – 0.0030; B12 – 0.0006 mg/kg body weight) and 4th D (B1 – 0.070; B2 – 0.10; B5 – 2.0; B6 – 0.40; B10 – 0.0050; B12 – 0.0010 mg/kg body weight) groups, and the smallest – in calves 1th D (В1 –0.015; В2 – 0,03;  В5 – 0.5; В6 – 0.10; В10 – 0.0012; В12 – 0.0002 mg/kg body weight) group.

This pilot investigation aimed at studying the feasibility of using a low dose (0.2%) of dietary microalgae as a means of improving intestinal morphometry, body weight, and selected meat quality parameters in broilers. A total of 72 one-day-old ROSS 308 male chicks were randomly separated into four groups; three experimental pens in which the birds were fed with biomass from Tysochrysis lutea, Tetraselmis chuii, and Porphyridium cruentum over 30 days and a control group. T. chuii and P. cruentum had a positive effect with regard to body weight. In treated animals, duodenal and ileal sections showed characteristic tall and thin villi, with serrated surfaces and goblet cell differentiation. In both sections, values of the villus-height-to-crypt-depth ratio were increased by microalgae ingestion. The thawing weight loss of fillets was reduced in T. chuii-fed animals. The positive effects exerted by T. chuii and P. cruentum on intestinal architecture were associated with the improved body weight. Arguably, these outcomes exhibit the potential of using these species to enhance growth performance in broiler chickens by promoting gut homeostasis and thus nutrient absorption.

In poultry farming, the management of feed inputs is decisive in production. This study is to optimize the feed use of sogobalo in breeding broilers to improve growth performance. To do this, five feeds different by their proportion of sogobalo were formulated and used to feed five batches of broilers in the growth phase. Each of the five batches received a specific feed. The five feeds under study consist of a growth staple supplemented respectively with 0%; 2.5%; 5%; 7.5% and 10% of sogobalo. In order to assess the effect of the supplementation rate of sogobalo, body weight, feed intake, weight gain, and consumption index and mortality rate were determined. The results showed that the animals which received the incorporation of sogobalo at 10% were the heaviest (3282 g ± 17.00). The consumption index was lower in the batch of chicken whose sogobalo supplementation was 10% (3.17 ± 1.00) compared to the other batches (3.36 ± 1.00; 3.54 ± 1, 00; 3.76 ± 1.00 and 3.95 ± 1.00 respectively for animals of the batches of 7.5%; 5%; 2.5% and 0%). The weight gain was significantly (P˂0.05) higher for the 10% supplemented group (529 g ± 10.00). No mortality was observed in the supplemented batch. On the other hand, in the control batch, a higher mortality rate (4%) was recorded. The supplementation with 10% of sogobalo optimizes the growth performance and the health of broilers.

Aleutian mink disease (AMD) caused by parvovirus is a real curse of the industrial mink breeding worldwide. Most minks infected with the AMD virus die, so the symptomatic treatment is aimed to extend the life of diseased minks until the fur maturation. This review contains an analysis of data obtained from the use of Gamavit (GM) and Phosprenyl (PP), which are widely used in practical veterinary medicine, including in fur animals, and have therapeutic efficacy for treating other parvovirus infections of carnivores. Both drugs were administered to minks by mixing with feed at the rate of 0.1 ml per kg of body weight for GM and 0.05 ml per kg of body weight for PP. In efficiency studies of the drugs on healthy animals, it was shown that they had a positive effect on the resistance of animals to adverse impacts (infections, feeding disorders, weaning). GM was most effective for increasing the fertility and number of kits per female, as well as for reducing the alimentary anemia, while PP was effective for increasing the survival rate of kits and contributed to their growth. Both drugs stimulated phagocytosis, increased SBA and SLA. The combined use of PP and GM increased the survival rate of young animals by 7.3% and the number of kits per female by 0.45 animals, as well as increased the number of defect-free skins by 7%. In addition, it eliminated anemia and increased the level of hemoglobin and erythrocytes in minks affected with AMD, although they did not reach the lower limit of the norm. Moreover, the use of PP and GM increased the number of kits per female by 0.7 animals vs. control, while the mortality rate of young animals reduced by 9.8%. Thus, the combined use of GM and PP in minks can increase the main natural resistance indicators (SBA, SLA levels, phagocytosis indicators, the absorption ability of peripheral blood granulocytes, the activity of natural killer cells) and significantly reduce anemia. Furthermore, the combined use of the drugs can increase the survival rate of young animals, the number of kits per female, reduce the live weight decrease in kits and increase the number of defect-free skins.

The cultivation of poultry without the use of antibacterial drugs is a vital direction of modern production, since the entry of domestic poultry products to the foreign market involves their absence in raw materials of animal origin. As experience confirms, enrichment of feed rations with enzyme preparations and vitamins reduces the waste of young animals, significantly increases the feed absorption, and reduces their feed-gain relations per production unit. This allows enhancing the productivity of poultry farming while simultaneously improving the quality of resulting products. We have studied the effect of the new vitamin-enzyme complex Vitaferm on the broiler-chickens body against the background of the antibacterial drugs exclusion from their antiepizootic measures. Studies have shown a positive effect of Vitaferm on the poultry body which is manifested by an increase in average daily growth, livability enlargement and reduced feed-gain relations per production unit. These changes can be explained by the normalization of the digestive system of broiler-chickens with the Vitaferm use. It is known that antibiotics inhibit the body’s immune system and disturb the balance of intestinal microflora. Thus, the use of vitamin-enzyme complex Vitaferm with broiler-chicken feed at the rate of 15.0 g/kg, starting from the day-old up to 10 days, is proposed for the complete or partial exclusion of antibacterial drugs from the antiepizootic measures scheme.
