Published: November 2019

Abstract
The use of probiotic supplements that normalize the microbiocenosis and enhance the resistance to pathogenic microflora can increase safety and meat productivity of farm animals. The aim of the article is scientific and practical substantiation of the increase in rabbit productivity using girasole beet pulp and the “Sporothermin” probiotic complex. The effects of the “Sporothermin” girasole beet pulp on safety, productivity, physiological status and chemical composition of rabbit meat were studied. 30 cross-bred rabbits aged 45 days were selected. The control group received the basic ration consisting of the PK-90 feed; the experimental groups received the PK-90 feed which included the probiotic complex “Sporothermin” (0.6 g/kg and 1.0 g/kg) and girasole beet pulp (10% to the feed weight). The quality of meat was evaluated at the age of 120 days after the control slaughter in the amount of 3 heads from each group. The data of morphological composition showed that rabbits of the experimental groups had a larger muscle tissue mass than rabbits of the control group by 9.07% and 20.15%, respectively. The analysis of the muscle tissue composition showed that the use of the Sporothermin at a dosage of 1.0 g/kg and girasole beet pulp at a dosage of 10% to the feed weight weight increases the average daily gains and meat productivity, improves the chemical composition which was confirmed by testing the data in the conditions of the industrial company “Lipetsk rabbit” and assessing physicochemical, functional, technological and organoleptic indicators of the resulting meat raw materials.

Abstract
Objective of the study: to determine the impact of "Geprim dlya kur" on the morphobic and chemical parameters of rearing flocks and the subsequent productivity of laying hens in the prevention of hepatosis. The drug was used once in the first day of life as an intramuscular injection. In the course of the experiment, blood and liver were taken for morphological, biochemical and histological studies in poultry of the experimental and control groups during the growing season at intervals of 1 month. It was found out that in the experimental group the preparation stimulates protective and respiratory functions of blood that was expressed in increase in number of leukocytes, erythrocytes and hemoglobin. In the experimental group, the Geprim increases the protein-synthetic function of the liver: in the experimental group of young animals, the level of total protein, albumins and the ratio of albumins to globulins was higher during the two months of the experiment. In the blood serum of experimental chickens, the activity of aspartate aminotransferase increased during two months of the experiment. Alanine aminotransferase activity in the experimental group was higher only in the second month of the experiment - 38.5% in relation to control group. By the end of the third month it decreased in relation to the control group by 36.3%. Histological studies have shown 1. dystrophic liver lesions of young animals are observed during the whole period of cultivation in the form of fat and protein dystrophy; 2. application of heprim reduces the accumulation of fat in the liver by 24.53-43.15%; 3. the preparation prevents protein dystrophy with the achievement of maximum effect by 2 months and further during the whole period of cultivation; 4. Geprim stimulates cellular factors of liver protection. "Geprim dlya kur" in the application of chickens allows obtaining greater productivity from laying hens for 24 weeks. The total number of eggs was higher by 29340, productivity per initial laying hen was higher by 1.6 eggs, per average laying hen - by 0.8 eggs.

Published: November 2019

Abstract
The article presents experimental data on the use of different levels of protein concentrate supplement in the diets of lactating cows with a high proportion of indigestible protein in the rumen. During the course of the research it was observed that the inclusion of Agro-Matic protein concentrate in the amount of 1.0 and 1.5 kg per head per day in the diet instead of other protein feeds increased the level of indigestible (by-pass) protein by 6.3 % and 9.1 %, respectively. The introduction of the maximum amount of Agro-Matic protein concentrate into the diet has contributed to the change in the amino acid composition of milk. It was established that the yield of milk protein during the period of milking was significantly higher in animals receiving different levels of protein concentrate compared to those of the control group. Feeding lactating cows diets with different levels of protein concentrate did not have a negative impact on biochemical parameters of animal blood. All measured blood of experimental animals were within the physiological norms. The maximum content of essential amino acids in the milk of cows from 3 experimental groups was significantly higher and reached up to 1560.9 mg% versus 1480.17 mg% in the control group.

Abstract
The article presents results of the development of a method for improving metabolic processes in immature piglets. In order to achieve the purpose of the research, pharmacological preparations were selected taking into account the nature of changes in metabolic processes in piglets in a state of acquired immaturity. For this purpose, effects of riboflavin, Vicasol, potassium succinic acid and their combinations were determined separately. It was established that feeding immature piglets with acid potassium (0.125 g) combined with riboflavin (2.5 mg) and vicasol (0.3 g) for 18-21 days improves metabolic processes, ensures the growth and development of animals. Increased development of macroergs decreases the levels of lactic acid and fatty acids, restores semipermeable properties of cell membranes and mitochondria, improves the conjugation of respiration processes with oxidative phosphorylation. Metabolic processes become improved; values of the parameters reach those of mature animals. The method of improvement of metabolic processes in piglets in a state of postnatal immaturity is simple, does not require special equipment and technology. Its implementation removes 100% of the animals from the state of immaturity and increases their live weight by 42.8; the average daily gain is 33.1, the safety level is 39.7%.

Abstract
At present, the priority areas of agrarian science development and scientific support of the agricultural sector of Russia until 2025 are connected with the development of high-tech technologies aimed at finding fundamentally new, environmentally safe and effective methods of intensifying technological processes, improving them, and creating a system of resource-saving technological processes and machines. Current trends in science and technology, from the standpoint of healthy nutrition state policy and implementation of anti-crisis measures in the Russian agro-industrial complex should be focused on developing competitive new generation food products that are promising in terms of import substitution and increasing domestic demandIntroduction. In our work, a significant increase in MEL was revealed in the intestinal mucosa in poultry, when cavitation-treated products were added to their diet. At the same time, the most pronounced increase was in the experimental group using zeolitized tuff, in comparison with group that received cavitation-treated wheat bran.
Thus, this section of the study confirmed that long-term use of such products significantly improves the morphofunctional activity of liver and small intestinal mucosa, it is greater when cavitationally processed products are introduced into the diet, especially when zeolitized tuff is added.

Abstract
The purpose of the study was to compare the morphological characteristics of Hereford mature herd of different body types at various stages of ontogenesis. Work was carried out in LLC “AF Kalininskaya” of Chelyabinsk region on two groups (n = 15 individual seach) of Hereford cows which are daughters from sires of different body conformation type. Newborn offspring from tall parents were characterized by significant (P < 0.01-0.001) superiority of body length and chest girth characterizing the axial part of the skeleton, and the development of altitudinal measurements characterized the growth of the peripheral skeleton. Later intergroup differences became less noticeable in the linear growth of heifers, which was associated with the limiting factor of dams’ milk productivity, as well as with the pronounced precocity of compact animals. Intensive development of body measurements ended at 15 months of age in animals with compact body type. They reached fully formed skeletal structure at the age of 5 years in terms of basic measurements. Tall individuals have the ability for a longer linear growth up to 6 years of age. The pronounced precocity of compact animals was confirmed by the variability of body volume and area of animals. The results of the study proved that the most noticeable differentiation of cows into body types occurs at later stages of ontogenesis.

Abstract
The aim of the study was to investigate the nature of changes in the genetic structure of the Orlov Trotter breed under the influence of the introductory crossbreeding used in the 60s of the 20th century. We analyzed the results of the genotyping of 6700 trotters registered in the Stud Book of the Orlov Trotter breed on 16 microsatellite loci. The differences between the descendants of purebred and crossbred Orlov Trotter horses were determined by the level of polymorphism and heterozygosity. It was found that in the group of Orlov Trotters pedigree of which did not contain ancestors of other breeds, the expected heterozygosity (He=0.709) was slightly higher than the observed heterozygosity (Ho=0.707) with a positive value of the inbreeding coefficient (Fis=0.004). In all groups of Orlov Trotters, pedigree of which contained ancestors of other breeds in various combinations, the inbreeding coefficient Fis had a negative value. The maximum differences between the Fis values were observed between the group of Orlov Trotters pedigree of which did not contain ancestors of other breeds and the group of Orlov Trotters pedigree of which contained ancestors of 3 other breeds: American Standardbred, Russian Trotter and Thoroughbred.

Abstract
The article presents data on studying effects of the enzyme preparation “Rovabio” in rye-containing diets for broilers of the cross “Smena-7” at the age of 14 to 42 days. It was revealed that the inclusion of the enzyme preparation “Rovabio” in the dose of 50 g/t in the combination with trace elements CoCO3 (0.57 mg/kg of feed), Cr2(SO4)3*6H2O (0.38 mg/kg of feed) with the replacement of 15% of wheat to 15% of rye into the diet demonstrated a positive impact of the used dosages of the trace elements on digestibility of organic matter (6.49%), crude protein (4.59%), the protein synthesis and stimulated hematopoiesis in birds. The multienzyme complex increases the integrity of chickens to 96.7% and profitability of poultry meat production by 2.0% due to endo-1.4-ß-xylanase and endo-1.3(4)-ß-glucanase.
Influence of diets with the various nutrient provision on the mineral metabolism in broiler chicken’s organism
Authors: Vishnyakov A I 
Published: November 2019

Abstract
The intensive development of industry in recent years led to the problem of the environment pollution and the survival of humanity in these circumstances became the central challenge today and affected all spheres of human activity. In some cases, technological processes have gone out of control resulting in the rapid accumulation of substances which are uncharacteristic for biosphere (radionuclides, heavy metals, and other toxicants).
As it is known, the blood system and organs of hematopoiesis are the most sensitive, so-called “Critical systems”. In some cases, changes in the blood occur under relatively small doses of substances and may be the only diagnostic indicators of diseases and their consequences.
Studying the influence of the feeding level on mineral metabolism causes some interest due to the application of different poultry feeding modes. In addition, the application of some new food means reduces the overall consumption of fodder due to low palatability, which proves the importance of such research once more.

Published: November 2019

Abstract
Nowadays, one of the environmental problems is the pollution of the environment with heavy metals, the release of which leads to accumulation in the body of animals. The aim of the research was to study the content of heavy metals in the body of cows of different breeds in a separated agricultural enterprise. Researches were held in LLC "EIF Solyanskoe" of Krasnoyarsk region. The objects of research were the blood, urine and milk of cows Red-Motley breed and Black-Motley breed at the age of the second lactation. The result of research determined that concentration of Cu, Zn and Pb in milk and blood serum of Red-Motley cows was more than in Black-Motley cows; on the contrary, in urine the concentration of the studied metals was higher in Black-Motley cows. In general, the content of heavy metals in milk, blood serum and urine of cows of both breeds did not exceed the maximum permissible concentrations, with the exception of Pb in milk, the existence of which was slightly higher than the hygienic norm by 0.02–0.03 mg/kg.

Published: November 2019

Abstract
The article presents data on the elemental status of highly productive Holstein cows in in terms of duration of productive use. The elemental status was studied on the composition of animal hair. Elemental analysis of samples was carried out by AES-ICP and MS-ICP. It has been established that the first lactation cows differed in minimal concentrations of As, Hg, Cd, Sr wool. With an increase in toxic elements with aging, an increase in zinc levels in the fourth lactation cows was recorded. A significant correlation was found between the sum of toxic elements (As, Hg, Sr, Cd) and concentrations of Cu (r = -0.57), Mn (r = 0.49), Se (r = 0.68) and Zn (r = -0.56) in wool. An assessment of the elemental status of cows in relation to the boundaries of the “physiological norm” revealed an increase in the number of deviations with an increase in the productive use ifrom 2 to 11.

AbstractThe study is conducted on Thoroughbred stallions. The first stage covered the study of the elemental composition (20 elements) of stallion hair (n=148) raised in the southeast of Russia (Stavropol Territory, Krasnodar Krai, Volgograd and Rostov regions). On the basis of obtained results 10, 25, 75, 90 percentile intervals of concentration of the main essential and toxic elements in hair were established. At the second stage, the stallions raised on the farms of Stavropol Territory (n=29) and Krasnodar Krai (n=32), as well as Rostov (n=24) and Volgograd (n=28) regions were examined. Hair samples were selected from mane area in the first cervical vertebra projection. Proximal part of hair (15 mm long) was selected from the hair root for analysis. The elemental analysis of samples was made via inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled mass spectrometry (ICP-MS). It is established that the hair of stallions raised in Stavropol Territory had the highest concentration of Al, As, Sn and Hg at a reliable difference (p≤0.05) with similar indicators for species from Krasnodar Krai. The typical feature of animals raised in Volgograd Region was the maximum concentration of Cd, Pb and Sr fixed against the background of the minimum Cr, I, Mn and Se values. All studied micro-populations were characterized by the excess of established norms of toxic metals. The most considerable deviations (2.5-6.9 times) of aluminum, mercury and tin were typical for animals raised in Stavropol Territory. The species from Krasnodar Krai had lower concentration of zinc. The assessment of the frequency of deviations of the element status from the norm showed that the zinc content in the hair of 48.3% of examined animals from Stavropol Territory and 50.0% of species from Rostov Region made more than 75%. A large number of species from Krasnodar Krai was characterized by the lack of iodine (46.9%) and selenium (34.4%) against the background of the minimum values of cadmium (50.0%) and mercury (100%).

AbstractAnnotation. The study was performed on clinically healthy cows of Holstein breed during the period of milking in the CJSC "Gatchina" of the Leningrad region (Russia). Animals (n = 60) were divided into groups depending on the severity of "loaded metabolism" estimated by lead concentration in wool: up to the 25th centile, within the 25th to 75th centile, above the 75th centile. The concentration of lead in wool was determined by atomic emission and mass spectrometry (AES-ICP and MS-ICP). It was found that about the increase in lead content from the minimum to the maximum in centile intervals from 25-75 to> 75, the level of malondialdehyde (Total-MDA) in the blood increased, which was recorded against the background of a decrease in milk productivity. A significant negative correlation was observed between the concentration of lead in wool and the yield of milk fat, protein, dry matter, and corrected for 1% milk fat.

Abstract
The purpose of the study was to apply the method of individual correction of elementosis to increase the reproductive qualities of white-faced cows. The deficit of iodine and selenium in wool (I <0.28 mg/kg, Se <0.58 mg/kg) and low reproductive abilities (more than 2 months without estrous period) served the selection criterion of animals. The animals were divided by analogs into 2 groups – control (n=15) and experimental (n=15). On the 1st and 10th day the experimental animals were subjected to intramuscular injection of commercial formulations (10 ml) containing in 1 ml: iodine – 5.5-7.5 mg, selenium in organic form - 0.07-0.09 mg (corresponds to 0.16-0.20 mg of sodium selenite. It is found that the cows of the experimental group were characterized by the increase of I and Se content on the 28th day, which fell within permissible values (25-75 percentile), while the concentration of Ca, K, Mg, Na, Zn, Al, Sr, Pb, Hg decreased in relation to the beginning of the experiment. The assessment of reproductive qualities of cows showed that in the first month of the experiment 46.7% of cows came in season in the control group and 60.0% – in the experimental group. Within the next month the control group saw additional 20.0%, while the experimental group – 33.3%. During the first service of breeding 66.7% of cows were bred in the control group, 80.0% – in the experimental group. In the control group two cows were aborted, which reduced the number of living calves in the control group to 7 or 47%. The experimental group gave 14 calves or 93%.

Published: November 2019

Abstract
Investigation of the effect of silicon dioxide nanoparticles on the processes of reproduction in cattle was performed on heifers of the breeding age of red steppe breed. Synchronization of the sexual activity by double use of the estrophan, prostaglandin drug, with addition of a releasing hormone (surfagon) to the scheme before insemination was performed in the control and experimental groups. Heifers were simultaneously injected with a solution of silicon dioxide nanoparticles with estrophan injection intramuscularly in the experimental group. All animals were inseminated in frontal, rectocervical way, with deep frozen sperm, twice. Heifers were taken the blood at estrophan injections and before insemination to study the dynamics of progesterone levels. As a result, 50.0% of the heifers were fertilized from frontal insemination in the control group, in the experimental one - 70.0%, that is, the increase in fertility with the use of silicon dioxide nanoparticles was 20.0%. Progesterone level in blood serum of the heifers on the 11th day of the experiment exceeded the initial by 23.5–69.2%, and before insemination it dropped by 38.1 to 50.0% compared with the maximum value. These changes were more significant in animals of the experimental group. Presumably, the use of silicon dioxide nanoparticles increases the hormonal activity of heifers’ ovaries, which contributes to their higher fertility during insemination.
