The trial was designed in order to examine the impact of flax seed in the nutrition of young cattle/bulls, in the final stage of the fattening. In the trial, 30 bulls of Simmental breed of uniform initial weight were selected, divided into 2 groups (control and experimental). The control animal group did not consume flax seed as a food supplement. Cattle of the experimental group consumed flax seed in an amount of 3.75% (300 g per day) of concentrated meal in the last 90 days of fattening, i.e. 300 g per day. The study included the examination of the fattening performance, slaughter traits and the composition of the bovine carcass. After slaughtering, warm carcass sides, with and without kidneys, were measured individually. Subsequent to period of cooling, the left carcass side it was cut into the main carcass parts according to the Rulebook. The results of the study showed that the addition of flax seed in the diet did not have a statistically significant effect on the body weight of bulls at the end of the trial. It was found that the addition of flax seed in the feed during the final stage of fattening did not have an impact on the differences in the average overall gain of bulls and the feed conversion ratio. Based on the data obtained by cutting of carcass sides to main parts, it was established that feeding with flax seeds had no significant effect on the share of carcass parts.

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.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

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 level of profitability of beef production in the experimental groups was higher than in control at 4, 18-of 1.29%.

The article presents the results of research on the influence of cadmium load on the body of young cattle. The purpose of the work was to investigate morphological indices of bulls blood during the development of experimental chronic cadmium toxicity. According to the morphological analysis of the quantitative and qualitative composition of blood, it is possible to deem objectively about the functional state of the hematopoietic system of the organism of young cattle. The research was  conducted (on the basis of the farm of the village of Ivanivtsi, Zhydachiv rayon of the Lviv region) on 10 bulls of six months old, Ukrainian black-and-white milk breed, which were formed in 2 groups of 5 animals in each: control and experimental. Bulls of the control group were in the usual diet. Bulls of the experimental group were fed with a feed with cadmium chloride at a dose of 0.04 mg/kg body weight of the animal. It has been established that feeding Bulls with cadmium chloride in a dose of 0.04 mg/kg of body weight contributed to a decrease in hemoglobin to 84.5 ± 1.60 g/l and an increase in the content of methemoglobin to 5.2 ± 0.099%. The decrease in hemoglobin levels is due to the toxic effect of cadmium on erythrocytes, resulting in damage to erythrocyte membranes and increased content of methemoglobin. Formation of methemoglobin in bull blood during cadmium loading occurs as a result of oxidation of hemoglobin with the formation of superoxide anion, which in turn triggers (begins) free radical processes and exerts a destructive effect on cell membranes, as well as initiates the appearance of other active forms of oxygen. Feeding calcium cadmium chloride in a dose of 0.04 mg/kg contributed to a decrease in the number of erythrocytes in their blood. At day 20 of the experiment, the number of erythrocytes decreased by 14% relative to the control group. Decreasing the number of erythrocytes in the blood of young cattle may have been due to the inhibition of their production in the bone marrow. An important morphological indicator of blood is the determination of the average content of hemoglobin in one erythrocyte, which indicates the saturation of erythrocyte with hemoglobin. It was found that the average hemoglobin content in one erythrocyte of the bulls of the experimental group increased by 11.4 and 13.9% for 5 and 10 days. According to the results of the research, the reduction of the hematocrit values in the experimental group of bulls was detected at 10, 15 and 20 days of the experiment. A significant increase in the number of leukocytes in the blood of the bulls of the experimental group was observed at 15 days of the experiment, according to the control group indicators, it increased by 12%.

Изучен метаболизм азотсодержащих соединений в организме телят-молочников и бычков на откорме при включении в рационы кормовой добавки N-карбомилглутамат (NCG). Введение в основной рацион NCG приводит к снижению уровня свободного аммиака в плазме крови телят-молочников в 2 раза относительно контрольной группы. У молодняка на откорме в опытных группах концентрация аммиака в плазме крови была меньше на 20,9% в 1 группе и на 54,2% во II группе. При этом в опытной группе телят-молочников зафиксировано повышение прироста массы тела на 5,01% по сравнению с контролем. Введение кормовой добавки NCG способствовало переводу токсичного аммиака из плазмы крови, вследствие активизации орнитинового цикла в клетках печени и стенке рубца с образованием избытка карбомоилфосфата и синтеза эндогенного аргинина. Экзогенный аргинин из корма может быть заменен на NCG в рационе у жвачных животных. Добавление NCG в корм или ЗЦМ позволит улучшить утилизацию аммиака, повысить эффективность использования белка рациона, устойчивость к стрессам и будет являться фактором повышения продуктивности молодняка крупного рогатого скота. The influence of the metabolism of nitrogen-containing compounds in the body of dairy calves and calves on fattening was studied when the feed additive N-carbomylglutamate (NCG) was included in the diets. The introduction of the NCG feed supplement into the main diet leads to a decrease in the level of free ammonia in the blood plasma of dairy calves by 2 times compared to the control group. In fattened calves in the experimental groups, the concentration of ammonia in the blood plasma was less by 20.9% in group 1 and by 54.2% in group II. At the same time, in the experimental group of dairy calves, an increase in body weight gain was recorded by 5.01% compared to the control. The introduction of the feed additive NSP contributed to the transfer of toxic ammonia from the blood plasma, due to the activation of the ornithine cycle in the liver cells and the scar wall with the formation of an excess of carbomoylphosphate and the synthesis of endogenous arginine. Exogenous arginine from feed can be replaced with NCG in the diet of ruminants. The addition of NCG to feed or ZCM will improve the utilization of ammonia, increase the efficiency of the use of protein in the diet, resistance to stress, and will be a factor in increasing the productivity of young cattle.

The article presents the results of research on the effect of cadmium load on the body of young cattle. The negative effect of Cadmium on the liver causes a wide range of pathological changes at different levels of its organization. The impact of heavy metals on the immune system is particularly significant, because it performs a leading role in maintaining health and is recognized as one of the most sensitive to adverse factors, even in relatively low concentrations. The aim of the study was to investigate the influence of cadmium on the cellular part of the immune system of young cattle. The research was carried out on 10 bulls of six months of age, Ukrainian black-and-white dairy breed, which were formed into 2 groups of 5 animals each: control and experimental. The bulls of the control group were on a normal diet. Animals of the experimental group were administered cadmium chloride at a dose of 0.04 mg/kg body weight of the animal. It was found that feeding bulls with a diet of cadmium chloride, the number of B-lymphocytes on the 5th day of the experiment was 17.54 ± 0.95 %. The lowest number of B-lymphocytes was on the 20th day of testing – 15.12 ± 0.37 %. The study of the number of T-lymphocytes shows that at the beginning of analysis the number of T-lymphocytes in the blood of animals of the control and experimental groups ranged from 40.70 ± 3.62 and 40.85 ± 2.54 %. Subsequently, the number of T-lymphocytes in the blood of the experimental group began to decline. The lowest number of T-lymphocytes was in the experimental group of animals on the 20th day of the research, compared with the control group, this figure decreased by 3.63 %. The state of immunity of animals under cadmium load significantly depends on the ratio of T-helpers to T-suppressors. It was found that the immunoregulatory index of blood of bulls of the experimental group probably decreased from 10 days of the research. The number of T-helper lymphocytes in the blood of the experimental group of bulls under cadmium loading is probably reduced by 15, 20 and 30 days of testing. A probable increase in the number of T-suppressors was noted in the bull's blood of the experimental group on the 20th day of the research. Immunoglobulins of different classes are crucial among bull’s serum proteins under cadmium loading. The concentration of immunoglobulins in the blood under cadmium load decreased by 15.9 % relative to the control group on the 20th day of analysis.
