Purpose. To study the effect of addition of hulless oats during the growing period on the qualitative and quantitative indicators of replacement-brood stock of carp. Methodology. The replacement-brood stock of Lubin intra-breed type of Ukrainian scaly carp strain, which were kept in ponds of State Enterprise Experimental Fish Farm of Lviv Research Station of the Institute of Fisheries of the National Academy of Agrarian Sciences of Ukraine (IFNAASU) was used for the study. The stocking density was 1000 fish/ha. The experiment was based on four experimental groups. Carps of the first experimental group were fed during the entire growing period with a feed mixture with the addition of hulles oats in the amount of 10 %, while carps of the second group were fed with a feed with the addition of 30 % of hulless oats. The third experimental group received a feed mixture in June – July, and hulless oats in August. The control group of carp was fed with the feed mixture throughout the entire growing period. The stocking density of fish was 1000 fish/ha. Piscicultural studies were conducted in accordance with current methods. Sampling of water for chemical analysis and its processing in the laboratory was carried out according to O. Alokin according to the Standard of the Ministry of Agrarian Policy of Ukraine. Haemoglobin content was determined by the haemoglobin-cyanide method. Blood erythrocytes were counted in a Goryaev chamber. Abundance and weight of natural feeds in ponds were determined according to I.A. Kyseliov, V.I. Zhadin. Zooplankton biomass was determined using tables of individual weights of F.D. Mordukhai-Boltovskoi. Analytical processing of the material was performed using MS Excel. The criteria for the analysis of indicators were their mean (M) and mean deviation (m). Findings. Peculiarities of growth, development of carp and efficiency of feed usage with the addition of hulless oats on the background of similar satisfactory growing conditions were studied. It was found that additional feeding of carp with hulless oats at an amount of 30% was effective. In particular, its addition resulted in an increase in individual weight by 31.1% and survival rate by 2.33%.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Abstract For the harmonious development, intensive growth and preservation of young animals in the diet it is necessary to include various feed additives, complexes, adaptogens that enhance the metabolic processes in the body. The purpose of the study is to study the feasibility and effectiveness of the use of adaptogen in calves rations. To achieve this goal in industrial conditions, 30 calves of Holstein breed at the age of 5–7 days were selected and divided into two groups of 15 animals each. The duration of the experiment was 90 days. Calves of the experimental group in milk, and then in concentrates included adaptogen “Energy” in the amount of 250 mg / kg body weight. The control animals were fed according to the standard scheme in the farm. The feeding mode for all calves was in accordance with the growing technology. The adaptogen includes: succinic, citric acid, inulin, oligofructose, methionine, lactic acid bacteria immobilized on aluminosilicate (patent RU 2493725). The results of the experiment (table 1) showed that the inclusion of an adaptogen provided a high growth rate throughout the entire period. At the end of the experiment, the body weight of calves of the experimental group was 6.52% (P > 0.05) higher compared to the control.

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%.

The article gives scientific substantiation of using silicon-containing new feed additive “Energosil” for replacement gilts. The studies were conducted in pig-breeding complex of the Center for Practical Training of Agricultural Specialists in Mordovia Republic. There were three experimental groups of replacement gilts (10 animals each). The effect of various dosages of Energosil (5.0, 7.5, and 10 mg per kg of body weight) on digestibility, nutrient utilization, and animal growth energy was studied. The most optimal dosage of a new feed additive in their rations was revealed, which constituted 5 mg / kg of the animal live weight. It was established that the animals from the first experimental group, who received silicon-containing feed additives of this amount digested the nutrients of the diet better than their counterparts from the other groups. Compared to the control group, the digestibility of dry matter increased by 3.62% (p<0.05), organic matter by 3.29% (p<0.01), crude protein by 4.09% (p<0.001), fat by 4.30% (p<0.01), cellulose by 3.79% (p<0.01) and nitrogen-free extractives by 2.03% (p>0.05).Replacement gilts of the first experimental group, who were given Energosil in the amount of 5 mg / kg body weight in addition to the basic ration, retained nitrogen in their bodies by 17.1%, calcium by 55.9% and phosphorus by 69.7% more than their counterparts from the control group. It contributed to an increase in body weight of gilts from the first group compared to control counterparts by 10.8%. Increased dosages of Energosil (7.5 and 10 mg / kg body weight) also had a better effect on the growth energy of gilts compared with the control group. The feed additive in the amount of 7.5 mg kg of animal  live weight contributed to an increase in animal weight compared with control counterparts by 6.21 kg or 4.8% (p<0.05), with a third experimental group by 4.4 kg or by 3.4% (p<0.05). When given Energosil in the dosage of 10 mg/kg, the body weight of gilts from the third experimental group was higher by 1.81 kg or 1.4% (p> 0.05) compared with the control counterparts.

The influence of naked oats on pisciculture, biological, hematological and biochemical parameters of commercial carp groups, as one of the components of the feed mixture in different ratios has been studied in the article. The aim of the experiment was to increase the fish productivity of ponds and to reduce feed costs for cultivation by meeting the physiological needs of commercial carp groups when using naked oats in carp feeding. The object of the study was age–1+ carps of Lubin scaly and framed intra-breed type of Ukrainian carp breed. For this purpose, three experimental groups of fish were formed by the method of analogues. Fish of the first experimental group (from July 1) were additionally introduced 30% of naked oats into the main diet, the fish of the second experimental group - 50% of naked oats, the third group was fed a feed mixture without added oats. As a result of the research done, it is proved that the addition of a mixture of naked oats has a positive effect on fish biological and physiological parameters of commercial carp. It was found out that the most effective is the additional feeding of naked oats in the amount of 30%. In particular, when the very amount of naked oats is added to the basic diet, the total fish productivity indicator increases by 7.7% relative to the control pond indicators, and feed costs are lower by 16.7%. The amount of hemoglobin in the blood of the first experimental group was higher relative to the control group, and the number of erythrocytes was significantly higher (P> 0.01). However, in the carp serum of the first experimental group the level of superoxide dismutase (P> 0.02) significantly increased while the level of catalase decreased.

As a result of the researchers found a positive effect of new feed additive on the growth rate, the qualitative indicators of meat fattening. It was found that the effect of feed additives on the productivity increased with increasing doses of feed additives from 100 to 300 g per head. Thus, at the age of 18 months, the bulls of the first experimental group surpassed the control analogues by 3.86, the second – by 5.53 and the third – by 6.42% and the average daily increase by 7.50, 11.63 and 12.45%, respectively. On the basis of the control of the slaughter was revealed that the weight of the paired carcasses in calves from the experimental group was higher than that of peers, not consuming the Supplement, of 5.82-of 9.91%, and their output is up 0.09 to 0.86 percent. At the output of the pulp of the bulls of the experimental groups exceeded the control analogues by 0.72-1.05%. The meat index of their carcasses was, respectively, higher by 0.25-0.36. In average the sample of the flesh of the carcasses of young animals who consumed the study Supplement contained more protein compared with the control 0,28-0,57% fat, respectively 0,68-1,19%. The influence of feed additive and on the content of amino acids in meat was revealed. Thus, essential amino acid tryptophan in the longest muscle of the back of the bulls of the experimental groups was higher by 1.58 – 2.87% and protein quality index-higher by 0.37-0.63. The flesh of the carcasses of calves of the experimental groups had higher technological properties. The moisture-retaining ability of their longest back muscle was higher than that of analogues of the control, by 2,05-2,22%, the fading – lower by 2,04-2,41%. In the body of young cattle, consuming feed additive, protein was postponed more than in control, by 8,67-14,85% and fat – respectively by 11,96-21,44%. The conversion rate of protein they were higher by 0.78-0.86%, energy - respectively 0.67-1.06%.

The article deals with the results of research to study the digestibility of nutrients in the ration and metabolism of Nitrogen, Zinc and Manganese in high-yielding Holstein cows of German selection in the first period of lactation for feeding mixed ligand complexes of Zinc, Manganese and Cobalt. The research was performed in the conditions of Terezyne Ltd., Bila Tserkva district, Kyiv region. There was an increase in the coefficients of digestibility of dry matter in cows of the 2nd-5th experimental groups compared with animals of the 1st control group, respectively by 1.8–3.5 % (P < 0.05); organic matter by 0.3–2.5 %; crude protein by 0.5–4.2 % (P < 0.05 – P < 0.01); crude fat by 1.1–1.8 %; crude fiber by 1.3–3.3 % and nitrogen-free extractives by 2.1–4.2 %. Cows of the experimental groups consumed more Nitrogen than the cows of the control group: 20.18 g or 2.4 % – the 2nd group, 55.06 g or 6.6 % – the 3rd, 42.52 g or 5, 1 % – 4th and 28.98 g or 3.5 % – 5th experimental group due to better eating of the feed mixture. General consumption level of Nitrogen in relation to excreted with milk and deposited in the body of cows of the control group was 32.02 %, and in animals of the 2nd, 3rd, 4th and 5th experimental groups – 33.59 %; 37.31; 36.99 and 34.97 %. In relation to the total digested amount, the proportion of Nitrogen deposited in the body and excreted with milk in animals of the control group was 42.38 %, and in the experimental – 44.25–47.34 %. Doses of Zinc, which provided its existing rate of 54–85 % due to the mixed ligand complex, positively influenced on the the metabolism of trace elements in the organism of experimental cows. Assimilation of Zinc in the organism was determined by the amount of its secretions with milk and deposits in the body and in absolute terms it was the lowest in cows of the 4th and 5th experimental groups – 562.7 mg and 671.6 mg against 740.8 mg in the 1st control group and the largest – 784.7 mg and 801.3 mg in animals of the 2nd and 3rd experimental groups. The use of a mixed ligand complex of manganese ensured its positive balance in the organism of cows and the absorption of the trace element in the organism of experimental cows ranged from 22.5 % in the 2nd experimental group to 33.2 % in the 3rd experimental group. The best indicators for the metabolism of Nitrogen, Zinc and Manganese were got in the third experimental group whose cows were fed a feed mixture, that in 1 kg of DM contained, mg: Zinc – 54.7; Manganese – 54.7; Cobalt – 0.7; Selenium – 0.3; Copper – 12 and Iodine – 1.1.
