A study of the safety of the use of feed additive Liaform for the target species – broiler chickens. Liaform is a yellowish liquid with a specific odor. The feed additive contains lactic acid, formic acid, sodium formate, propionic acid and water. Given the composition of the additive, it can be attributed to two functional groups: preservatives – substances or microorganisms that protect feed from damage by microorganisms or their metabolites, acidity regulators – substances that regulate the pH of feed. For the study was formed on the principle of analogues of 3 groups of broiler chickens of 15 heads (control and 2 experimental) from 8 days of age. Feeding of chickens of the control group was carried out by standard complete feed. Feeding of chickens of the first experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg, feeding of chickens of the second experimental group was carried out with standard complete feed, in which feed additive Liaform was applied in 10 times the recommended dose of 20 g/kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It was found that the studied feed additive in 10 times the recommended dose does not have a negative impact on productivity, growth and development of broiler chickens, feed absorption. As a result of the use of Liaform feed additive in 10 times the recommended dose, the live weight of broiler chickens in the experimental group was higher compared to the control and lower compared to the recommended dose. The use of a feed additive in 10 times the dose did not have a negative effect on hematological parameters and serum protein levels, did not cause a negative effect on the condition of internal organs.

The results of the influence of feed additives: acidulent Versal liquid and probiotic bifidobacteria PKB on the growth dynamics and some hematological and immunological parameters of broiler chickens are presented in this article. The research was conducted on 30 broiler chicks. There were formed 3 groups. There were 10 chicks in each of them: a control group didn't get any feed additives; 1–st experimental group got feed and acidulent Versal liquid solution at the recommended dose of 1 ml /1 l of water; 2–nd experimental group got feed with probiotics bifidobacteria PKB at the recommended dose of 1g / 1kg of feed and acidulent Versal liquid solution at the recommended dose of 1 g/1 l of water. The 15th and 30th day blood were collected for hematological and immunological parameters checking.It was found, chicks that have got feed additives achieved more intensive increasing of average live weight and daily gain during this period. The live weight of broiler chicks from the second experimental group was higher at 76.5 grams, compared with the control and the 136.6 h – compared with I research group in case of using acidified and probiotics bifidobacteria. Average daily increasing were 49.93 g in the control group, 48.21 g and 52.36 g according to another experimental groups. There was a tendency of hemoglobin increasing on the 30–th day of experiment in all experimental groups. The hemoglobin concentration increased by 1.09 times in the 1–st group and in 1,20 times in the 2–nd group. The number of leukocytes was increased in the experimental group. It was also increased by 16.6% in the 1–st group and by 44.4% in the 2–nd group. Phagocytic activity of pseudo eosinophils increased in all experimental groups on the 30–th day of the feed additives using. The most important increasing by 7.2% was in the 2–nd group. There was also a tendency of the phagocytic index increasing in all experimental groups of chicks on the 30–th day of this investigation. It was established that the using of acidulent and PKB probiotic preparation of food at feeding broilers improves hemoglobin levels. It also promotes to leukocytosis, phagocytic pseudo eosinophils activity and improves the overall condition and immunological reactivity.

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 influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.

A study of the effectiveness of the use of feed additive Liatoxil in vivo in broiler chickens to study the ability of feed additives to improve digestion and affect the digestibility of nutrients. For research was formed on the principle of analogues -day age. Feeding of the control group was carried out with standard feed. Feeding of the experimental group was carried out with standard feed, in which the feed additive Liatoxil was added at the rate of 2 g / kg. The calculation of the digestibility of nutrients of the experimental and control feed was determined by their content in the feed and manure in terms of absolutely dry matter. It is established that the studied feed additive has a positive effect on the digestibility of feed nutrients. As a result of the use of feed additive Liatoxil, the digestibility of organic matter increased by 2.8 % compared to the control. The coefficient of protein digestibility in animals of the experimental group exceeded this indicator of the control group by 4.2 % and was 93.3 % against 89.1 % in the control. The digestibility of crude fat in poultry of the experimental group was 77.8 % and also exceeded by 2.0 % the value of the control group, which was 75.8 %. The studied feed additive did not significantly affect the digestibility of crude fiber, which was 23.3 % in the control and 23.5 % in the experiment. At the same time, the obtained data show that in the animals of the experimental group the digestibility of nitrogen-free extractives was 87.5 %, which is 2.8 % higher than this indicator of the control group.

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.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).

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
