Abstract
The rotary crusher allows you to qualitatively grind pressed roughage. The authors proposed and developed an improved technological scheme of an impact crusher equipped with two beaters for dosed transfer to the grinding chamber. The impact crusher consists of a transfer chute, metering beaters, a chopping chamber, a rotor, chopping knives, fixed knives, an exit chute, a feed bin and an electric motor. The efficiency of work is determined by the following parameters: length, width and thickness of knives, rotor speed. The purpose of the work is to substantiate the parameters of the rotor and its knives. Analytical dependencies are obtained to determine the parameters of the knife. Theoretical studies have established that the minimum length of the knife should be 6.9 cm, the width of the knife is 50 mm, and its thickness is 4 mm. A model for the theoretical calculation of the probability of grinding roughage of the required size within the limits of zootechnical requirements has been obtained. Based on the calculations, the probability of cutting the feed of the required size, depending on the number of rotation of the rotors, was established.

Abstract
Although the natural conditions of Uzbekistan do not allow to start fishing on a large scale, in order to meet the needs of the population for fish meat and products, attention is being paid to the development of this industry at the level of possibility. In Uzbekistan, fishing is mainly raised in naturally and artificially created ponds of 1-2 hectares, in reservoirs and lakes up to 5 hectares in size. One of the most important tasks in raising fish is to feed them properly and to distribute nutrients equally. However, due to lack of equipment used in fish feeding, this process is done manually. This makes it difficult to feed fish in larger ponds or during rainfall, and it is not possible for them to distribute the food evenly. Considering this we conducted research on the development of a device that distributes food to fish, and an experimental sample of the device was developed. The mass of the device is not more than 100 kg, it can penetrate up to 3 m into ponds and basins, and when necessary, for example, when loading feed into a hopper, it is possible to move back and bring it to the edge of the pond.

The big relevance is acquired by issues of development of methods of receiving phosphors, and studying influence on their spectral characteristics of features of structure. Red phosphors which part compounds of europium are of particular interest. Ions of europium have such properties as rather big difference of energy between its resonant and the main levels, providing radiation in the visible range; not degeneracy of these levels; the most important transitions are poorly subject to effect of the crystal field; a good possibility of the theoretical description of the processes happening in the materials containing europium ions. Ranges of a luminescence of the system received by continuous joint sedimentation of hydroxides (CDH) of europium and aluminum at a stage of crystallization of amorphous products are measured. The complex research of the CDH system is conducted by methods of the physicochemical analysis: differential and thermal, IK-spectroscopic, X-ray phase, X-ray fluorescent, power dispersive. The dependence of intensity of a luminescence of a system, from synthesis conditions is analyzed: concentration of initial components, structures of firm phases, temperatures, time (after a year of aging).

Published: August 2022

Abstract
The sedimentation process is of great importance in the purification of drinking water. To improve the efficiency of horizontal sedimentation tanks for drinking water treatment, it is recommended to use thin-layer sedimentation tanks. Experimental studies of the effectiveness of water distribution methods in a thin-layer sump were carried out on model and semi-industrial installations. The settling tank model was made of organic glass at a scale of 1:12. In accordance with the scale factor and the Froude criterion, Qo, tp, Vp were determined. An analysis of the research results showed that for all values of m, the closest approximation of Vph to Vr was achieved when the upper edges of the plates were located along a curve calculated using a method that considers the water flow in the distribution volume as a flow of variable mass. KOI at the same time exceeded 90%. It has been established that with a 3-4-fold increase in the hydraulic load of the sump with the proposed method of water distribution, its KOI decreases slightly (from 92-95% to 74-85%), while with the location of the upper edges of the plates along an inclined or horizontal straight line, the KOI decreases from 68-83% to 15-20%. For the conditions of production operation of sedimentation tanks, where, depending on the time of day, year and production technology, the amount of drinking water can vary widely, this circumstance is of particular importance. As a result, the efficiency of the drinking water treatment process will be increased.
Prospects for the use of artificial intelligence in the agricultural sector

Published: August 2022

Abstract
The relevance of the study is due to the fact that there is a rapid development of artificial intelligence technologies, due to breakthroughs in the digital environment and the uncertainty of their application in the agricultural sector. It should be noted that Russia plays an important role in the world history for the development of these technologies, but the Soviet management model limits the rapid development of digital technologies in modern Russia. Artificial intelligence technologies are of particular importance, as they are used for big data analysis, robotics and as the basis for various forecasting algorithms. The article reveals the role of artificial intelligence in solving complex tasks in agriculture, identifies the main barriers to the introduction of digital technologies and identifies perspective direction of application for artificial intelligence technologies. Due to the lack of scientific developments on this issue, the lack of research on the feasibility and effectiveness of the using artificial intelligence, the lack of methodological recommendations for the introduction of these technologies and systematic training of artificial intelligence, it is difficult to use artificial intelligence in agricultural organizations. For Russia, the issue of agricultural automation is particularly important: over the past 10 years, the number of workers in the industry has more than halved. In the future, automated systems can improve rural areas and keep production there, since most of the rural population is no longer engaged in agriculture. Agriculture remains one of the most important and largest industries, and even a small increase in efficiency will lead to a significant increase due to its scale.

Weather risks in grain production
Authors: Kumratova A M , Chupin R I , Aleschenko V V , Aleschenko O A 
Published: August 2022

Abstract
Grain production depends primarily on weather conditions. The paper provides a comparative detailing of meteorological factors affecting the productivity of grain production in the world. The main global factors in the context of climate change that affect the world indicators of the productivity of grain production are natural and climatic conditions with the corresponding Rhesus (risk-extreme values): air temperature during the growing season of grain crops (abnormal heat/frosts); precipitation in the spring-summer period (drought/showers). Based on the analysis of the group of meteorological factors that affect the productivity of grain production, presented by the authors, we can conclude that there are factors of global warming, which leads to a change in productivity and has sharp reversals in the form of “recession/rise". Moreover, speaking about the further development of these agricultural systems, one can state the presence of uncertainty in factors, both objective and external (precipitation, temperature). In this case, by risk we mean the randomness and uncertainty of results in the agricultural sector of the grain-producing territories of the world, which is higher than in other areas of human life.

Published: August 2022

Abstract
With the globalization of production, all countries in the world are working to reduce greenhouse gas emissions. Agriculture accounts for about 11-12% of the total, with methane emissions from the digestive tract of ruminants and nitrous oxide from manure, especially when stored in open lagoons, being the main sources in livestock production. The aim of the research was to analyze existing technological measures to reduce methanogenesis in dairy cattle production. The volume of intestinal fermentation products in dairy cattle depends on the growing technology, the number of livestock and the amount of roughage in the diet. By optimizing feed, methane emissions can be reduced by 10-15%, with high levels of degradable starch and low fiber content contributing to the reduction of methanogenesis. Special feed additives show good results in combating methanogenesis. The introduction of plant extracts into the diet of animals affects the change in the taxonomic composition of the microbiome of the gastrointestinal tract of animals. New phytogenic additives containing essential oils, herbs and spices and used in feed rations not only contribute to optimal productivity and profitability, but are also the best solution to reduce emissions of harmful gases in animal production. Some plant metabolites, especially esters, have the effect of reducing the breakdown of carbohydrates and proteins in the rumen by selective suppression of some microorganisms and at the same time have a positive effect on reducing methane emissions. The use of phytogenetics fits harmoniously into the strategy of organic, environmentally friendly cattle breeding. Due to the limited amount of data on the problem of methane emission reduction in dairy cattle breeding, it is promising and relevant to continue research on the mechanism and ways to control methanogenesis in the rumen of cows using natural additives of plant origin.

Abstract
The publication assesses the productivity of a herd of sheep of the Salsk breed of the leading breeding plant. Breeding queens of the herd have a moderate supply of skin, characterized by one-and-a-half half-ring folds on the neck, a developed burda or apron. In some animals, the skin folding is increased and they have 1-2 full folds on the neck, wrinkling along the trunk, enlarging to the back. In bright women, this feature is less developed. In recent years, the folding of the skin, as a breeding feature, has changed in the herd. The number of multi-tabbed rams was 2.5%, queens - 2.2%, bright-1.6% and yearling rams-0.7%. With a small supply of leather, the number of sheep increased: queens - up to 16.6%, rams-2.7%, yark - 1.1% and yearling rams-0.9%. In the studied sheep of different sex and age groups, the difference in the length of the wool on the side and back does not exceed 1.5 cm, which corresponds to the standard of sheep wool productivity. The length of the wool in the rams was 10.87 cm in 2018, 12.42 cm in 2019 and 13.26 cm in 2020. In bright colors, respectively, 11.38; 12.88 13.42 cm. In terms of their average live weight, producing rams exceed the requirements for elite animals of wool breeds by 20%, repair rams-by almost 40%, queens and yarkas correspond to the level of elite animals of wool-meat breeds. The factory lines of its own breeding of sheep-producers No. 510 and No. 585 represent the genealogical structure of the breeding flock of sheep of the Belozernoye GPP. Adult sheep of line № 510 have an average live weight of 107.5 kg, and line № 585 – 106.3 kg. With relatively equal values of the quality of wool productivity, the best indicators of live weight (by 8.12%) and hair cutting (by 7%) characterized the elite queens of the sheep line No. 510. In the herd of the breeding plant, it is planned to continue work on the creation of a fine-haired line (20-21 microns) with improved meat qualities and start

Dependence of the amount of feed distribution in the small-sized feed distribution device on the number of rotations of blade rotor
Authors: Choriev R K , Khudaynazarov D Kh , Israilova D A 
Published: August 2022

Abstract
Livestock is mainly raised on small family livestock farms with 5-10 heads of cattle or 50-60 heads of sheep in Uzbekistan. Although there are small devices that are used to grind feed for these farms, due to the lack of a feed distribution device, feed distribution work is carried out manually, spending a lot of work. With this in mind, a device was developed that is used in the distribution of feed for small farms, and a change in the feed distribution norm was studied depending on the number of rotations of blade rotor. According to the results of the experiments, the distribution quality of corn, trefoil and straw stalks of coarse feed is selected according to the amount of one-time feed in the daily ration of livestock (between 4-5 kg for corn and trefoil, 2-3 kg for straw stalks), which was achieved when the number of rotations of the feed distributor blade rotor was 50 r/min. Due to the fact that the density of corn, trefoil and straw stalks differs from each other, it was determined that there would be a change in the amount of feed distributed, although the number of rotations of blade rotor of the device is the same.
