HISTOARCHITECTURE OF THE THYROID GLAND IN PIGLETS WITH HYPOTROPHY AND AFTER THE COURSE OF MEDICAL CORRECTION
Abstract
Antenatal malnutrition is a condition characterized by both a weight loss in animals and a change in the morphofunctional characteristics of the internal organs, particularly the incompleteness of the thyroid gland structure that will have a direct impact on the further growth and development of animals. Therefore, the aim of the research was to establish the patterns of histostructure of the thyroid gland inhypotrophic piglets and piglets after prenatal correction of hypotrophy considering their age. The study was performed on piglets of the large white breed. The study material was the thyroid gland of hypotrophic piglets and piglets after prenatal correction with Sedimin at 1, 5, 15 and 30 days of age. The main methods of study: histological, morphometric and statistical data processing. According to the research results, a thickening of the connective tissue capsule of the thyroid gland in newborns and five-day-old hypotrophic piglets was established in relation to fifteen and thirty-day-old ones. The average diameter of the follicle is at a relatively equal level during all periods of the study, the colloid acquired a “foamy” appearance on the fifth and fifteenth day. The form of thyrocytes and their nuclei changed with age from flattened to cubic. Cell-tissue composition of the thyroid gland of piglets after prenatal correction of malnutrition is functionally active. On the first and fifth days the capsule of the organ was thinned, by the end of the study its thickness increased markedly. The diameter of the follicles of the thyroid gland decreased from the neonatal period to the thirtieth day. Throughout the experiment, the structure of the colloid changed in the follicle lumen from homogeneous consistency to “frothy” by the end of the experiment. At the beginning of the experiment, both flattened and cubic-shape epithelial cells were observed in the parenchyma of the thyroid gland, by the thirtieth day it was stably cubic. The nuclei of thyrocytes are mostly spherical and hypochromic. In conclusion, it is worth noting that in hypotrophic piglets in the neonatal period and in the five-day age, the incompleteness of the structure of the thyroid gland was observed, the further morphological reorganization reached by the thirtieth day. The medication “Sedimin” had a positive effect on the body of pigs, reducing the degree of development of malnutrition and contributing to the adequate organoand histogenesis, including the thyroid gland.
RADIATING PATHOLOGY IN AGRICULTURAL ANIMALS WITH A DISEASED THYROID GLAND
Abstract
Radioactive iodine is present in atmospheric fallout during the first hours of accidental emissions at nuclear power plants. It causes damage to the thyroid gland of varying severity. As a result of lesions with radioactive iodine, pathological changes develop in the thyroid gland, which can affect the productive indicators and reproduction of farm animals. Physiological changes are also diagnosed in animals that do not receive a sufficient amount of iodine compound with food or water. This can lead to pathology of the thyroid gland. Studies of the pathology of the thyroid gland should be carried out on the basis of structural modeling methods and data obtained experimentally. Analysis of the comparison of pathological effects allows to systematize information and use it in scientific and practical purposes. Depending on the intensity and duration of external and internal radiation exposure in farm animals acute or chronic radiation diseases can be diagnosed. Farm animals with or without signs of radiation disease of mild severity are left in farms and used for its intended purpose. Long-term effects of radiation can be manifested as temporary or permanent sterility, metabolic and endocrine status disorders, immunodeficiency, increased sensitivity to infectious diseases, the emergence of tumors. Monitoring of the radiological situation on the territory of the livestock complex is of particular importance, as its products are transported to different regions. Livestock products must meet regulatory requirements. Timely and full implementation of general and specific rules in the field of radiation safety is aimed at ensuring the safety of animals and preserving the quality of animal products.

Abstract
Identifying the main land legislation violations in Volgograd is a prerequisite for the preservation and rational use of the territory. The measures system development aimed at improving the effectiveness and efficiency of the municipal land control implementation will contribute to the city district main wealth preservation. The article presents the activities of specially authorized organizations and bodies for the land legislation observance. The average workload per 1 specialist in municipal land control carrying out amounted to 1.4 of inspections carried out for legal entities. The sequence of actions during the scheduled and out-of-scheduled inspections is given here. The report on the municipal land control carrying out in Volgograd for 2016-2017 is submitted. According to the land control results in 2016, from the total number of carried out inspections, 16.5% of them were revealed with violations, and in 2017 - 25.7%. Amount of the prescribed fines in 2017 increased by more than twice in relation to 2016. Violations of land legislation in Volgograd occurred on the unauthorized occupation of land plots and their parts, the failure to comply with legal regulations on the violations elimination, the use of land not in accordance with its permitted use. Municipal land control was carried out in compliance with the general principles, duties, restrictions and prohibitions in carrying out control measures, as well as the requirements for processing the results of inspections. On the basis of the material reviewed, suggestions were made to improve the effectiveness and efficiency of the municipal and state land control implementation.

EFFECTIVE CULTIVATION OF EXTRA-EARLY SOYBEAN CULTIVAR CV. ‘VNIIOZ 86’ UNDER IRRIGATION
Abstract
The influence of sowing methods and irrigation regimes on productivity of extra-early soybean cultivar VNIIOZ 86 has been studied at Russian Research Institute of Irrigated Agriculture. The use of differential irrigation regimes (70-80-70% and 80-80-70% of FMC) resulted in 2.42 ... 2.51 t/ha yield and mid-level profitability of grain production (80.6%), which was 0.25 ... 0.34 t/ha more compared to the control (80-80-80% of FMC), as synchronization of vegetative growth and reproductive development increased grain amount in total biomass up to 36.2%. Differential irrigation regimes restrained an increase in crude protein level in the seeds (at the level of 35.4 ... 41.2%) compared with the control (36.5 ... 41%). However, they increased fat content in the seeds (18.1 ... 21.4%) compared to the control variant (16.1 ... 18.6%). Optimization of irrigation regime increased protein (up to 0.68 ... 0.94 t/ha) and fat (0.37 ... 0.46 t/ha) compared to the control (0.64 ... 0.83 t/ha and 0.29 ... 0.35 t/ha, respectively). The smallest water consumption coefficient was observed in sites with differential irrigation regimes - 1,174 ... 1,524 m3/t, when in the control site it was 1,651 ... 1,977 m3/t. Extra-early VNIIOZ 86 plants require 8 ... 14 irrigations at a rate of 190 ... 230 m3/ha. It is enough to perform 8 irrigations in relatively favorable years (2013), and up to 14 irrigations in dry years (2014- 2015). To maintain a differential irrigation regime, it is necessary to perform 8 ... 10 irrigations in wet and up to 10 ... 13 irrigations in dry years. The highly profitable cultivation of early soybeans (107.9%) was achieved using drilled sowing (0.30 × 0.042 m) that resulted in significant yield increase (up to 3.02 t/ha) which was 0.41 t/ha higher compared to wide-space sowing technique (0.70 × 0.024 m).

IMPROVED TECHNOLOGY OF CARROT CULTIVATION UNDER DRIP IRRIGATION
Abstract
The article considers technologies of carrot cultivation of Shantene Korolevskaya hybrid under irrigation conditions on light chestnut soils of the Lower Volga region. Against the background of various methods of tillage, modern methods of using water-soluble fertilizers have been studied. It was found that deep chisel plowing with 0.18-0.20 m soil overturning results in 1.25 fold increase in productivity of edible carrot compared to moldboard plowing and blade cultivation. Using water-soluble fertilizer NS 30:7 through fertigation increases productivity by 7% compared with ammonium nitrate. Measurements of soil density showed that carrot yield averaged 1.25-1.32 t/m3 over 2015-2017. In variants after deep chisel plowing rate of water infiltration during all three research years was the highest and averaged 4.2 mm/min. The smallest water infiltration was observed in variants after blade cultivation. Using ammonia nitrate during fertigation in 1-4 applications and NS 30:7 fertilizer in 5-8 applications, and NS 30:7 fertilizer during all 8 applications increased carrot yield of hybrid Shantene Korolevskaya by 4.7-5.9 and 0.5-2.4 t/ha compared to control. In addition, combination of deep chisel plowing with ammonium nitrate fertigation in 1-4 applications and NS 30:7 fertilizer in 5-8 applications resulted in the highest carrot yield in 2015-2017 and averaged 90.6 t/ha. The lowest carrot yield over 2015-2017 was observed in the variant after blade cultivation with ammonium nitrate fertigation and amounted to 77.5 t/ha.
RICE LODGING RESISTANCE
Abstract
The main direction of breeding grain crops is to increase yield and improve grain quality. For maximum crop yield, it is necessary to develop cultivars with high productivity and quality potential, resistant to biotic and abiotic environmental factors. One of the main characteristics is lodging. Resistance to lodging is determined by well-defined morphological traits: plant height, diameter of the lower internode, panicle length, angle of leaf plate, etc. Short plants are more resistant to lodging than tall ones. Short straw trait can be used when evaluating cultivars for lodging resistance. The ratio of plant height to the diameter of the lower internode is an objectively reliable indicator of rice lodging resistance. The value of this ratio in non-lodging cultivars is less in comparison with lodging ones. The article presents the results of studying morphological traits of different rice cultivars, determining resistance of rice plant to lodging. In the experiment, cultivars differing in height was grouped into three groups (I - tall; II - medium and III - short). Short stem forms were established to be more resistant to lodging. Accents in breeding high-yielding rice cultivars with the lowest risk of yield loss resulting from lodging were identified. The correlation analysis revealed a positive relationship (r = 0.877; 0.945 and 0.500, respectively, in groups) between grain mass per plant and diameter of the lower internode. This indicates a close genetic relationship of the traits studied.
