The feeding effect of polyacrylamide (PA), mineral and vitamin additives (MVA) on the reproductive and productive qualities of sows, as well as the development and viability of piglets gained from them has been studied. The polyacrylamide, mineral and vitamin additives have been added to the sow diet of the 2nd and 3rd experemental groups. It has been done according to the animal need in minerals and vitamins. In proportion of 0,5/1 kg of live weight, the mineral and vitamin aditives, polyacrylamide have been added to the ration of sows from the 2nd experimental group. The mineral and vitamin aditives have been added to the ration of the 3rd group in such proportion: iron sulfate – 200, copper carbonate – 15, zinc – 84, cobalt – 3, manganese chloride – 69, potassium iodide (stabilized) – 170 mcg, vitamins A – 2.8 th. IO, D – 736 IO, B1 – 1.4 mg; B2 – 8.4 micrograms per head per day. The mineral and vitamin additives, polyacrylamide have been added to the sow diet of the 4th experimental group in the same proportion as it has been already mentioned above. The sows fed on PA and MVA for 60 days. The feeding was stopped 10 days before farrowing. The experiment on piglets has been carried out in 2 stages. The equalization period was 25 days (the ration of piglets from the control and experimental group was the same). The main period was 150 days (the control group of animals fed on standard compound fodder). The experimental group fed on additional PA and MVA. It has been noticed when the additives are added to the sow diet the gained piglets have an increase of viability, immun response (due to gamma globulins increase in blood proteins) and the average live weight by 23.3% during the rising period. Key words: sows, piglets, polyacrylamide, mineral elements, vitamins, live weight, albumin, globulins, rearing, fattening, feed costs, slaughter yield.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

The article presents the results of studying the effect of stocking density on the productivity of pigs while rearing.The research was conducted in PE "Kalynsky Klyuch" p. Kalyna Kamyanets, Podilskyi district, Khmelnytsky region. The scientific and economic experiment was performed by the method of analogous pairs, with a total duration of 73 days. The experiment was performed on young pigs for rearing. Animals were selected into groups based on age, life weight, health status, sex, fatness and growth energy during the preparation period. Four groups of pigs were formed. During the experiment, the animals were weighed, feed intake was taken into account, and their health was monitored. The productivity of young animals was determined according to the monthly individual weighing of animals, which were carried out 1-2 hours before morning feeding, and feed costs - based on group accounting. All data obtained in the experiment were processed biometrically. According to the results of the research, it was found that the most optimal is the density of pigs at the rate of 2.58 heads / m2. Analysis of the dynamics of live weight of experimental animals showed that with the same weight of piglets since the beginning of the rearing period and till the end of it, the weight of the animals differed significantly. The highest average live weight was recorded in the second experimental group, where there are 2.58 heads per 1 m2 of pigsty - 27.4 kg, and the lowest in the fourth experimental group, with a livestock density of 3.42 heads / m2, - 25.4 kg. The animals of the first control group (1.75 heads / m2) have a live weight of 27.3 kg, and the animals of the third experimental group (3.42 heads / m2) - 4.0% less. For farms in the fodder with natural and climatic conditions of the region, ready to use fodder as efficiently as possible and to obtain the maximum productivity of 4-breed hybrid piglets during the rearing period, we suggest using the livestock density at the level of 2.58 heads / m2 of the pigsty. Taking the recommendations into account is the way to achieve successful results in pig farming.

The results of establishing the optimal feeding doses of Zinc, Manganese, and Cobalt in the form of their mixed-ligand complexes for high-yielding cows of Holstein, Ukrainian Red-Spotted and Ukrainian Black-Spotted dairy breeds during the late dry period were presented, their influence on the future productivity and reproductive qualities of cows were also determined. It was found that lower doses of mixed-ligand complexes of Zinc, Manganese, and Cobalt in the feed mixture stimulated its consumption better. The cows of the 4th experimental group consumed more of the feed mixture, where the concentration of Zinc and Manganese was 35 mg, and Cobalt – 0.49 mg per 1 kg of DM. At various doses of mixed-ligand complexes of Zinc, Manganese, and Cobalt, the increase in live weight in cows of the control group was 24.3 kg, and in the experimental groups, it ranged from 23.7 kg to 26.9 kg, which is 8.6% and 10.7% (P < 0,05) more in the 3rd and 4th groups compared with the control. A decrease in the concentration of mixed-ligand complexes of Zinc, Manganese, and Cobalt in the diets of dry cows in the experimental groups by 10, 20, 30 and 40% had a positive effect on their further milk productivity. During the first 100 days of lactation, they milked 60-180 kg of milk more compared to the control with an increase in fat content by 0.01–0.05%. Also, in the milk of experimental group’s cows, compared with the control, the protein content increased (3.22–3.23% versus 3.14%), and the feed costs per 1 kg of milk in them were lower by 3.5–9.4%. Smaller doses of zinc, manganese, and cobalt contributed better to lengthening the period of prolonged action of their mixed-ligand complexes on the body of lactating cows. The calves’ live weight at the birth in the 4th experimental group exceeded the indicator of their peers from the control group by 2.3 kg or 8.81%, while the calves obtained from cows of the 2nd experimental group prevailed the control by 1.6 kg, or 6, 13 %, from the 3rd experimental group – by 1.8 kg, or 6.90%, and the 4th experimental group – by 1.7 kg, or 6.51%. The duration of the service period in all experimental groups of cows was within the recommended norms and was 87.8 days in the control group, and the 2nd, 3rd, 4th and 5th experimental groups, respectively 84.7 days, 82.2; 80.6 and 83.5 days, respectively, and there was less in control by 3.1–7.1 days or 3.3–8.2%. The insemination index in the cows’ control group was 1.5, and in the experimental one – 1.2–1.4, which is 6.7–20.0% less.

Abstract. In the domestic fur farming there is an urgent need to introduce an alternative type of feeding for young minks. The purpose of the work is to study possible of feeding commercial young minks with complete feed, consisting of animal and plant components. Methods. In a scientific and economic experiment on young sapphire minks intended for slaughter, 2 groups were formed according to the principle of analogues, 32 heads each (16 males and 16 females): I – control, II – experimental. The animals of the control group received from 2015 August 5 to September 15 a typical general economic ration in the form of a wet mash, an experimental one – a loose, complete feed (made according to a recipe developed by us, taking into account the current norms), mixed with water in a ratio of 1:2. All experimental studies were carried out using classical zootechnical, pathomorphological, histological, veterinary-sanitary and statistical methods. Results and scope. The dynamics of the live weight of the experimental minks showed that by the beginning of the main period, the males and females of the experimental group lagged behind the control animals, after switching to the main diet for slaughter, the males lag remained and the females caught up with the control animals. But the control and experimental animals did not differ in the length of the carcass. The safety of the livestock was higher in the experimental group: males – 100 %, females – 93.75 %; in control – 93.75 % and 87.5 %, respectively. According to the main productive indicator – the quality test – the skins of the control and experimental animals did not have significant differences. Thus, the development of an alternative type of feeding is quite possible, but it requires improvement in the direction of increasing the coefficient of digestibility of nutrients and adaptation of males to an uncharacteristic type of feeding. Scientific novelty. The prospects and the need to introduce an alternative type of feeding the commercial young stock of minks with full-feed compound feeds into the domestic fur farming are outlined.

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

Aim. Development of KR-1 concentrate compound feed compositions with the inclusion of malt sprouts, determination of the optimal rates for the introduction of malt sprouts into the compound feed for calves aged 10-75 days. Materials and Methods. In the course of the study, zootechnical, biochemical and mathematical methods of analysis were used. The obtained digital material was processed by the method of variation statistics, taking into account the Student's t-test, using the Microsoft Excel software package. Results. On the basis of the control feedings carried out for the period of the experiment, the actual diet of calves was established, which consisted of 64-67% milk and 24-25% of the starter compound feed. The rest of the ration consisted of corn and oats, cereal-legume hay and forb haylage. In terms of nutritional value and metabolic energy content, the differences between the groups were minimal from 2.27 feed. Units and 21 mj in 1 control up to 2.3 feed. Units and 21.7 mj in 2 experimental. The results of groups 3 and 4 were within the ranges listed above. The difference in the consumption of dry matter is slightly greater, so in the control group – 1396 g, in the experimental group it is 5.6-6.9% more. The higher consumption of compound feed by the experimental animals also contributed to the higher level of protein in the diet of 322-324 g versus 306 g in the control. As a result of feeding various mixed fodders, it was found that the sugar-protein ratio was 1.04 in the control, in the experimental ones it was at the level of 0.98-1.0, the energy-protein ratio was 0.3, the gross energy of the diet was 28.4 mj in the control. Experienced 29.9-30.2 mj, the coefficient of energy use to maintain 0.8, the ratio of calcium to phosphorus in all diets was 1.24-1.27 Conclusion. The highest productivity was noted in calves of the 2nd experimental group containing 5% malt sprouts in the compound feed, which amounted to an average of 806 g per head per day for 65 days of the experiment. Increase in the concentration of malt sprouts in compound feed by 5 and 10 pp. reduced live weight gain by 1.4 and 7.5%, respectively. Given that the 5% level in compound feed allowed an increase in growth by 9.3%. This influence, both positive in the 2nd experimental group, and negative in the 3rd and 4th groups, was also reflected in the feed costs for obtaining an increase, decreasing them by 7.3% and increasing by 2.3 and 8.5%, respectively. As a result, the expenditures of metabolic energy per 1 kg of gain in the control group were lower than in 3 and 4 experimental groups, the same tendency persisted in the consumption of crude protein for gain. More detailed indicators of the energy efficiency of the fed rations showed that the energy gain was 8.05 MJ in the 2 experimental group, which was fed with compound feed with 5% malt sprouts, the second result was a control of 7.1 MJ, and the 3 and 4 experimental groups were 1.5 and 9 , 2% were lower, respectively. The expenditures of exchange energy per 1 MJ in the increase in live weight in the 2 experimental group were lower than the control indicator by 0.26 MJ, and in the 3 experimental group – by 0.39 and in the 4 – by 0.64 MJ higher.

The scientific and economic experience was conducted in the Chuvash Republic. For carrying out experiments 3 groups of ducklings on 50 heads in everyone were selected and formed. Ducklings of the 1st experimental group received enzyme preparations amylosubtilin in the amount of 0.05 kg/t and protosubtilin in the amount of 0.05 kg/t during the entire period of growing together with feed. Ducklings for the 2nd experimental group of compound feed were enriched with enzyme preparations amylosubtilin in the amount of 0.1 kg/t and celloviridin in the amount of 0.075 kg/t. It was found that ducklings receiving enzyme preparations in addition to feed had increased growth energy throughout the experiment. By the end of the experiment, the live weight of ducks of the control group was 3,424 kg, the first experimental group receiving in addition to the feed enzyme preparations amylosubtilin in an amount of 0.05 kg/t and protosubtilin in the amount of 0.05 kg/t – 3,712 lbs. In the second experimental group, where the ducks advanced to the feed received enzyme preparations amylosubtilin in the amount of 0.1 kg/t and celloviridin in the amount of 0.075 kg/t, live weight to the end of the experiment amounted to 3,804 kg. The average daily live weight gain of animals in the control group was 53.52 g, and in the first experimental group - 58,10 g, in the second one - 59,56 g. The inclusion of a mixture of enzyme preparations with a compound feed of the experimental animals have contributed to the increase in body length compared to the control on average by 0.9 cm and 1.6 cm, length of tarsus by 2.5 cm and 4.3 cm, chest girth by 1.8 cm and 2.5 cm, respectively. The increased productivity of ducklings in growth was reflected in the reduction of feed costs and unit costs, which contributed to multiplying profits in the experimental groups.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

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.
