In order to put cultured species on the market with high quality and few casualties, many important studies are carried out. Most of the researches are conducted in the development of feed and feed ingredients 30-60% of the production cost in farming. Therefore, in aquaculture, an interest in alternative feed ingredients is moving at a very fast rate. In this context, the use of enzymes, probiotics and prebiotics in animal feed has steadily increased in recent years with reasons such as effective control of fish diseases and prevention of infection, strengthening the immune system of fish, increase of the digestibility, reduction of the feed cost, reduction of larval-term mortality, provision of increase in growth, live weight gain, and getting rid of the negative effects of stress.

Introduction. The article substantiates the need for high-temperature processing of feed ingredients. Principles of operation and design features of the applied methods and equipment for feed production are considered. Phase transitions, along with advantages and energy, technological, and technical drawbacks are highlighted. The aim of the study is to justify a possibility of creating high-efficiency production lines using heat treatment of feeds by application of heat valves ensuring continuous loading of raw materials into a reactor and discharge of the treated feed at high pressures and temperatures. Materials and Methods. It is proposed to transfer the process of barothermal processing to a higher zone of the phase diagram of the system p,t (pressure and temperature). This is a section of the superheated steam zone with temperature 300–374 °C, pressure 12–21 MPa and treatment exposure 30–60 seconds, which replaces costly processes of normalizing, expansion, extrusion and granulation. The change in enthalpy in the pressure range 0–21 MPa and temperature range 0–600 °C is shown. Thermal modes are presented as formulas which is the basic condition for the use of digital technologies. Results. The design of the reactor with a thermal gate for loading and unloading, being the main unit of the production line of the feed heat treatment, was proposed. The results of the study are fundamental for the development of the sample flow low-capacity line. Discussion and Conclusion. The transfer of the process of barothermic processing of feed into the zone of superheated steam allows for the transfer of poorly digestible elements of grain and legumes in easily digestible, pathogen-free feed. Advantages of the reactor and line include the user-friendly design, energy saving and possibility of implementation of advanced digital technologies.

Beef cattle manures have been converted to a water slurry and subjected to centrifugation, flocculution and drying to produce a silage replacement product (CI), a 20% protein powder from the centrifuge supernatant fluid (CII) and a soil amendment product (CIII). These products and the manure slurry were analyzed for their As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn content by atomic absorption spectrophotometry. Different sample mineralization techniques, metal recovery efficiencies and matrix effects were investigated. Metal concentrations increased in the products in the order of silage replacement, protein and soil amendment. Except for a high iron concentration, the silage replacement product (CI) had concentrations of these metals comparable to those for typical feedlot rations, and metal concentration in the protein fraction (CII) was three to six times higher as compared to the range of metal levels in CI; the soil amendment product (CIII) showed metal concentrations comparable to reported manure values. The effects of these metal concentrations on utility of the silage replacement and protein products as feed ingredients for animal feed rations is discussed.

This activity is based on potensial of Tete Batu Village as agricultural area so that the availability of agricultural waste is abundant and so far it has not been used optimally as animal feed.  Community service activities are carried out by providing materials on the technology of processing agricultural waste using various fermenters and local feed ingredients that can be used as alternative feed ingredients, then continuing the practice of processing livestock waste into liquid organic ferlizer and processing agricultural waste into silage.  The service activity was attended by the Lombok Regional Government which involved in fostering livestock, head and management of Tete Batu, the livestock farming community, alumni and student, avarage 40 people. The community service activities have succeeded in increasing the knowledge and skills of breeders in processing livestock waste into liquid organic ferlizer which can be used to increase the fertility of agricultural plants and become products that can be sold so as to increase the income of the livestock farming community. Community service activities have resulted in good commitment from the livestock farming community, village administrators and related local government agencies to assist livestock farming communities in processing agricultural and livestock waste into useful products.

Abstract A method using immunoaffinity column chromatography (IAC) and liquid chromatography (LC) for determination of zearalenone in cereal grains, animal feed, and feed ingredients was collaboratively studied. The test portion is extracted by shaking with acetonitrilewater (90 + 10, v/v) and sodium chloride. The extract is diluted and applied to an immunoaffinity column, the column is washed with water or phosphatebuffered saline or methanolwater (30 + 70, v/v), and zearalenone is eluted with methanol. The eluate is evaporated, the residue is dissolved in mobile phase and analyzed by reversed-phase LC with fluorescence detection. The presence of zearalenone can be confirmed using an alternate excitation wavelength or diode array detection. Twenty samples were sent to 13 collaborators (8 in Europe, 2 in the United States, one in Japan, one in Uruguay, and one in Canada). Eighteen samples of naturally contaminated corn, barley, wheat, dried distillers grains, swine feed, and dairy feed were analyzed as blind duplicates, along with blank corn and wheat samples. The analyses were done in 2 sample sets with inclusion of a spiked wheat control sample (0.1 mg/kg) in each set. Spiked samples recoveries were 89116, and for the 18 naturally contaminated samples, RSDr values (within-laboratory repeatability) ranged from 6.67 to 12.1, RSDR values (among-laboratory reproducibility) ranged from 12.5 to 19.7, and HorRat values ranged from 0.61 to 0.90.
