Studying the parasitic aetiology of diseases, their treatment and prophylaxis is important for environmentally safe production in goat breeding. On pastures, especially rural, parasite fauna is constantly present due to lack of pasture prophylaxis, uncontrolled animals circulation, instability and inopportune preventive measures before spring gazing. The article contains data about the contamination of goats with lungs helminths. 9 nematodes have been detected, high percentage of helminth infections is presented with Dictyocaulus filaria - 30.2%, P. hobmaieri - 23.2%, Muellerius capillaris - 41.8%; low percentage of infection - with nematodes P. davtiani - 9.3%, P. Scriabini - 4.7%. It should be noted that in the foothillvalley zone at high density of livestock on 1 hectare with the respective temperature and humidity mode, the percentage of goat infestation varies, and prevail mainly those types of worms that operate in the frame of natural ecosystems. Close contact with this group of helminths may concern sheep, hares, roe deer and other types of animals. It seems relevant to conduct ecological and biological research on this issue in order to create database for the helminthosis monitoring at the regional level.

The use of antibiotics and antimicrobials drugs without control may lead to the development of numerous complications and resistance of microorganisms to antibiotics. Using antibiotics and antimicrobials drugs should be controlled on farms. That is why the monitoring and determination of sensitivity of bacterial diseases agents to antimicrobial drugs are very important. The results of pasterella, of salmonellas’ and kolibakterias’ monitoring in Azerbaijanian farms are presented in the article. Microbiological monitoring of a number of farms in Azerbaijan has shown that agents of bacterial diseases are widely spread. Between the isolated pasterella agent largest number were accounted for Salmonella (54.1%) and the Escherichia (30.8%). The rest (15,1%) were isolated cultures of Proteus, Pseudomonas, Klebsiella, Salmonella, Campylobacteria, Enterobacteria, and Clostridia Citrobacter. This indicates that systematic control over the availability of the causative agents of bacterial infections in all critical points of farms is necessary. Among isolates that were isolated from ill calves and objects, differences in their sensitivity to antimicrobial agents from active substances that officially have registered in our country were discovered. Bactericidal activity of relatively isolated cultures was showed by oxitetraciklin, colistin, ftorfenicol, zeftiocur, doxicyclin, enroxil and sarafloxacin.

Great impact on the efficiency of livestock has improved the system of veterinary activities, including the use of available funds of natural origin. Agolin Ruminant is a mixture of high-quality active ingredients of plant origin which is designed to optimize consumption and improve feed conversion as well as to increase animal productivity in the dairy industry. The article reflects the results of useing plant extract in the feeding of lactating cows. Scientific and business experiences and production tests were carried out on the dairy complex in Tambov region. Analysis of the cows productivity indicates a positive effect from the introduction of Agolin Ruminant into the animals diet. The productivity has increased by 1.08 kg or 3.56%. After 30 days of the test, the average daily milk yield from one cow was 27.44 kg in the control group, and 28.14 kg in the experimental group, which is 700 g more. The composition of milk also became better. In addition, experimental animals using Agolin Ruminant did not have stressful behavior, their physiological state improved, as it was evidenced by biochemical blood parameters. The calculations show the efficiency and feasibility of using the Agolin Ruminant feed additive in feeding lactating cows. In the production test for 200 animals, the income per head per day increased by 17.3 roubles (without the cost of the feed additive). Thus, the rational use of feed additives can reduce the consumption of expensive chemotherapeutic agents and vitamins, increase and improve livestock production.

In 2017-2018, atZAO “Russkaya Svinina” (Kamensky District, Rostov Region), were carried out the researches of pigs' blood tested for immunobiological indicators and of selection aimed at increasing the offspring resistance. For the first time a breeding index was developed for a comprehensive assessment of the pigs immune status (IP). The index includes the numbers of Tand B-lymphocytes, immunoglobulins G. A, M, and phagocides. A new selection index of resistance (IR) designed to assess and select animals according to the level of protection of their organism against conditionally pathogenic micro flora has been developed. The index includes bacteriostatic, bacteriolising, antigen-binding and phagocytic properties of blood. Parental pairs of pigs were selected for resistance indices, the superiority of the offspring obtained from high-resistance parents was found according to bactericidal activity of blood serum by 3.75%, according to phagocytic index by 3.15%, according to phagocytic blood capacity by 110 million based on 1 liter, according to the general level of resistance - by 5.1 points, than the selection of low- and medium-resistant pairs with IR <40 and 35 points with maximum IR - 53.5 and 72.4.

The silkworm is the object that shows solutions of major genetic problems such as artificial regulation of sex, cloning, the theory of a complex of compensatory genes explaining the nature of heterosis and others are solved. Despite the progress made in the genetics of the silkworm, issues of genotypes interaction with the environment are still poorly studied. Breeding signs of the silkworm manifest themselves in certain conditions of keeping and feeding the caterpillars. This article presents the results of 3-years breeding work on the adaptation of large-scale and mid-cone populations to unfavourable conditions, for instance non-observance of the hygrothermal mode, non-observance of the optimum feeding area and amount of feed mulberry leaves. Moreover, during these three years of experiments, the control population was the variants of experimental rocks and lines, where the graene was obtained on the first day of laying. Control populations were much sturdier and more productive than experienced options. Large breeds were more sensitive to abrupt changes in caterpillar content. Thus, in the Guzal and Marvarid rocks, the cocoon mass in 3 experimental variants decreased by 24.4% compared to the control variant, where the caterpillars were kept in optimal conditions of the hydrothermal mode and feeding. In populations of high-tech lines No. 27 and No. 28, the deviation from the optimum by the mass of the cocoon for three selected generations under adverse conditions was not very noticeable. The same trend is determined by the mass of the silk shell in Line 27 (experience with non-compliance with the temperature regime).

Currently in a herd of Akzhaik meat-wool sheep breeding work is carried out to improve productive, tribal and biological qualities. breed properties through the use of genetic the potential of the gene pool of semi-fine sheep under conditions of Padno-Kazakhstan region. Studies were performed in OPH "Atameken" NAO ZKATU named after Zhangir Khan. Were formulated world groups and implemented the following options selection: Group I - rams-producers and queen akameat and wool breed; Group II - sheep- half-blooded North Caucasian meat-wool sweaters with Akzhaik meat-woolly uterus; Group III - Kui Byshevsk sheep manufacturing (in the type of Romney March) with Akzhaik meat-woolly uterus. The article gives The research data of productive indicators of Jaika meat-wool sheep and sheep producers North Caucasian and Kuibyshev breeds used in insemination of uterus, as well as reproductive ability the quality of the queens and the safety of the young. Determined that used in the experiment semi-fine-rooted rams meat and wool breed breeds with crossbred wool Steas were characterized by rather high rates. meat and wool productivity. Physical research co-technical properties of wool showed that they are requirements of a cross-bred homogeneous whoa. The average hair length of all queens was 11.2 cm, that meets the requirements of the first bonding class according to the standard. The results of lambing are Does the fertility of queens in compared groups groin was about the same and ranged within 92.0-96.0% with a slight advantage in the first group, where on both sides were Aczhaik sheep that exceeded the second and third groups by 3.0-4.0%. Waste lambs in all groups ranged from 7.0% - for ak Zhaikis and 2.6-2.7% - in hybrids of 1/2 CK and KB of rams. The best fecundity differed uterus first and second groups - 120.0 and 120.6%. Marked high business the course of the lambs in the selection options where the production The bodies of 1/2 SK and KB of rocks are explained by the effect of heterosis.

An experiment was conducted on three groups of rainbow trout. Fish in group one and two received abiopeptide and cobalt respectively with feed. The peculiarities of fish-breeding indicators were revealed and the main exterior, interior and morphological parameters were studied, and the feed costs for the production of 1 kg of products and the chemical composition of the rainbow trout musculature with addition of abiopeptide and cobalt were determined. It has been established that the use of abiopeptide and its complex with cobalt did not have a significant effect on the exterior performance of trout. Minor changes in the relative mass of internal organs were revealed. The use of the studied additives led to an increase in the dry matter content by 0.6-2.5%. This was due to an increase in the fat content in the muscles by 0.8-3.4% and a slight decrease in the protein content. In the experimental variants 1 and 2, the weight gain, the yield of ichthyomass, the growth rate increased in comparison with the control while the cost of feed and protein per 1 kg of weight gain were reduced. Therefore, the introduction of the complex of abiopeptide and cobalt into the main ration for feeding the trout helps to improve the physiological state of the fish.

The study was carried out in ZAO "New life" in Saratov region. The queens of the Stavropol breed of the local population were inseminated with sperm of halfbreed Australian meat merino of highly productive rams, and crossbred 1/4AMM + 3/4ST-blood offspring were received. Then these sheep were bred "in themselves". The productivity indicators of the offspring were studied at the age before a year and at 13-14 months. Then, reciprocal crossing of 1/4AMM + 3/4CT-blood hybrids with the main Stavropol breed was carried out and 1/8AMM + 7/8ST-blood-curled offspring was obtained, whose productivity indicators were studied at the age before a year and 13-14 months. The indicators of productivity were identified by consolidating the methods of selecting sheep in crossbreeding genetic group 1/8AMM + 7/8ST-blood, experimental data were analyzed and summarized when the local population of the Australian meat merino genotype was used on sheep of Stavropol breed. 1 /8-blooded by AMM bright Stavropol breed exceeded their purebred peers in live weight by 7.67% (P ≥ 0.999). In regards to unwashed wool, the superiority of brightly colored origin was 5.97% (P≥0.999), and in regards to pure wool, 1.46%. Wool with almost the same amount of mechanical impurities of hybrids less fatty (grease, respectively, 26.3% and 24.6%), has a lower indicator of iodine number of wool fat (respectively 21.9 and 20.5 units) and more light cream color. Thus, 1/8-blood mixed sheep of the Stavropol breed with the Australian meat merino at the age of 13-14 months as a result of consolidation of productivity indicators by the selection methods are characterized in comparison with purebred animals of the Stavropol breed with increased parameters of wool quality and live weight.

The article reports the new research data on testing the original Russian lubricant gel registered under the Doctor VIC trade name (import substitution) during the semen sampling. The semen was collected with the artificial vagina rubber tube and the disposable polyethylene gloves being labricated with the gel to use the recto-cervical artificial insemination technique and to operate the rectal procedure for clinical examination of cows and heifers with gynecological diseases. The sterile veterinary "Likom” Vaseline (Russia) was used as the control remedy for lubricating the artificial vagina. In case of the clinical examination of cows and heifers with gynecological diseases, the 1.0% sodium chloride solution was used. During the tests, 114 semen samples taken from 19 bull sires were analyzed. The behavioral response patterns of 179 cows and heifers with the gynecological diseases were studied during the clinical examination (90 experimental animals and 89 control animals). It has been ascertained that this Doctor VIC lubricant gel can contribute to the favorable environmental conditions during the sperm sample collection in the bull sires, which can be compared with the environments during the natural mating. It was contributed to both increasing the total sperm count in the doublet ejaculates by 13-21% and the number of the frozen semen doses by 12-36% and decreasing the frozen-thawed abnormal sperm by 28-36%, when compare to the control. In case of the rectal examination for gynecological problems, lubricating the disposable polyethylene gloves with the Doctor VIC gel contributed to a significant reduction in aggression and removal of various micro-deformations occurred during the rectal examination (for instance, blood occurrance after the examination), when compared to the control. Therefore, the new original Russian gel registered under the Doctor VIC trade name may be used for current application in the extensive zoo-veterinary practice.

The purpose of the research is to cultivate mixed bean and cereals herbage mixtures on the green conveyor under the conditions of the Central Yakutia. Scientific research on creation of the green conveyor was conducted in a scientific hospital of laboratory of forage production of FGBN YANIISKH. The sowing time of long-term herbs is summer. In the experience were used 6 options of cereal and bean herbs and their mixes. The results are presented in article. The optimum specific structure of the mixed crops, formation of herbage mixtures productivity have been established, the nutritional value of green material of long-term herbs from legume-grass herbage mixtures on the green conveyor has been defined. Accordinf to the results, the maximum productivity was created by lucerne (8) + awnless brome (15 kg/hectare) - 57.0 c/hectare of green material, with the maintenance of fodder unit 0.73, a digested protein of 158.4 g - 1sterns. piece.

The Sudanese grass is one of the most valuable annual fodder herbs of family of cereals. The drought resistance, high productivity, high quality of green material and hay, ability to grow quickly after beveling or drain, big and steady crops of seeds, - all this factors allow expanding seeds, promote rapid implementation of this culture in production making it one of the most valuable one-year forage crops. The Sudanese grass combines high efficiency and fodder advantages with drought resistance and ability to use a maximum of rainfall of the second half of summer that are common to our climate. For the first time the productivity and nutritional value of a Sudanese grass for preparation of juicy forages under the conditions of the Central Yakutia is studied. According to researches the studied sowing time is capable to form to 19.4-26.3 t/hectare of green material when beveling on juicy forages. From all three studied sowing time the best is the II sowing time (on June 15). High rates on productivity are observed in the second sowing time, at the same time the maintenance of a digested protein in 1 kg of SVmade 178 g, 0.67sterns. piece.

Vegetative reproduction of clonal rootstocks of stone fruit crops can be realized by various methods. For the final conclusion on the effectiveness of a particular method of propagating clone rootstocks, it is necessary to compare the costs with the results obtained, i.e. give an economic assessment of the method, which served as the basis for our research. The studies were carried out on the basis of a greenhouse complex with fogging installations of the base nursery of the research and production company Gardens of Chechnya. Studies have been conducted to evaluate the effective method of propagation of promising clonal rootstocks. The objects of research were the clone rootstocks VVA-1, L-2, Zarevo, and the VSL-2 stock was used as a standar. In the experience of grassy cuttings with a semilignified heel in the nursery garden, which is the main one in preparing the rootstocks before using for laying the first field of the nursery, comparing the economic efficiency of reproduction of new clonal rootstocks with the best standard VSL-2 rootstock showed that they are close in all the main indicators and quite cost-effective. In terms of economic efficiency of rooting of grassy cuttings, promising clonal rootstocks VVA-1, L-2 and Zarevo were only slightly inferior to the standard VSL-2 rootstock. The experience we conducted in comparison with the technology of growing seedlings of small-grain crops using unrooted and rooted cuttings in the conditions of the Chechen Republic showed that herbaceous cuttings with a semi-woody heel can be used in technologies involving laying the first field of the nursery rooted grass cuttings. This greatly reduces the cost of growing small-oriental-seedlings. Thus, promising clone stocks - VVA-1, L-2 and Zarevo can be effectively used in the conditions of the Russian south (including in the Chechen Republic) to produce high-quality planting material on a par with the standard clone stock of VSL-2.

The use of organic fertilizers from waste poultry farms can improve the properties of the soil, significantly increase their fertility, while growing environmentally friendly products. The work shows the need to process waste poultry farms into organic fertilizers by high-temperature drying. The features of the drying process of wet materials are determined, first of all, from the experimental kinetic curves of the process. Therefore, the goal was to study the kinetic patterns of drying chicken manure. The process of drying kinetics was studied in a dryer without convective movement of the drying agent in the working chamber of the dryer at a temperature of 150 °С and 220 °С. Fresh chicken manure with initial moisture content Wn = 72% was used as raw material. Based on the experimental data, the kinetic dependences of the drying process at different temperatures were constructed, from which the following conclusions were drawn: chicken droppings can be attributed to colloidal materials, as the drying temperature increases, the duration of the process is significantly reduced. The process of drying chicken manure at a temperature of 220 °С to a final moisture content of W = 10% lasts 3.75 hours, and at a temperature of 150 °С - 7 hours, which is 86% more in percentage terms at a temperature of 150 °С than at 220 °С. Changes in the nature of the kinetic curves on the dependence of the drying rate dW/dτ (%/s) on the moisture content W (%) can occur, not only because of the temperature difference, but also of changes in the thickness of the blown layer, the speed of the drying agent in the drying chamber, relative humidity of the drying agent. Therefore, to further build a mathematical model of the drying process for poultry farms waste, it is necessary to study the effect of all the listed parameters on the drying process. In the chicken litter, part of the moisture is in a free state, which can be mechanically separated in the field of centrifugal forces or by direct pressing on the press, which will shorten the process time and reduce energy costs.

The article presents the results of studies of the influence of fertilizers on the yields of white cabbage under the conditions of the Ganja-Gazakh region of Azerbaijan. The Ganja-Gazakh region is one of the most important among the economic regions of Azerbaijan from the point of view of a steadily developing agricultural sector. Growing vegetable crops in different climatic zones also contributes to the task. In this regard, we set the task to study the effect of mineral fertilizers on the background of manure in the Western zone of Azerbaijan as well as to determine the yield and quality of cabbage. The studies were conducted in the 2015-2017 years in the farm household in the Gedabek region in Morukhlu village which is located in the western part of Azerbaijan. The soil of the test site is carbonate, mountain black soil (post forest). The content of nutrients decreases down from the bottom in the meter horizon. In the experiment was used a variety of cabbage Azerbaijan. We can conclude that in order to obtain high and high-quality yield of white cabbage and to restore soil fertility on mountain black, farms are recommended to use manure 20 t/ha N₉₀P₁₂₀K₉₀ annually.

The article deals with the study of the influence of various resource-saving systems for the treatment of light-gray forest soil and the use of fertilizers and the biopreparation Stimix®Niva on the contamination of pea varieties of the "Beautiful” variety and its yield in the Nizhny Novgorod region. The highest contamination of pea crops was revealed in the variants of field experience, where it was cultivated according to the No-till technology as at the beginning (23.3-36.5 pcs/m² total, including 18.0-31.0 pcs./m² perennial contamination), and at the end (23.0-43.8 pcs./m² total, including 18.8- 39.8 pcs./m² perennial contamination) of vegetation. The use of Stimix®Niva when growing peas in accordance with the traditional tillage system by the end of its growing season on a non-fertilized background reduces the contamination of crops to 12.5 pcs/m². Between the total weed infestation of pea crops in the phase of full ripeness of grain and its yield, a strong inverse correlation was found, the correlation coefficient is -0.86. The highest yields of pea varieties "Beautiful” were obtained in the variants where in the system of the main tillage, autumn plowing was used with reservoir turns to a depth of 20-22 cm with the use of ammonium nitrate as a destructor at a dose of 10 kg per 1 ton of straw, as on the background mineral fertilizers (2.76 t/ha) and non-fertilized background (2.70 t/ha). With a decrease in the depth of processing of light-gray forest soil, a decrease in the yield of pea grain per hectare was revealed. When using the No-till technology, the yield of peas is the lowest - 0.74-2.24 t/ha. The use of the background of N₆₀P₆₀K₆₀ fertilizers according to the No-till technology together with the Stimix®Niva biological preparation, as a straw destructor, allows to obtain the pea yield in the Nizhny Novgorod region conditions of 2.24 t/ha.
