Modern domestic feed production is developing at a fairly steady pace, which is facilitated by the increase in the volume and scale of production in the livestock sector. Today, domestic agricultural pro-ducers fully provide the domestic market with pork, poultry and egg. the efficiency of the development of the livestock sector depends on the quality of feed and the fattening system by more than 60%. All this proves the relevance and prospects of studying the dynamics of the development of feed production in order to im-prove the manageability of this area of management, organizational support, identify potential risks and de-velop effective solutions to minimize them. As the basic provisions of the study, it is worth noting: key produc-tion segments of the domestic feed industry; production volumes of mixed feeds, premixes, feed additives and concentrates in Russia; market leaders in the production of mixed feeds at the time of 2019.; the reasons for the transition of large companies to self-feed; the negative factors (risks) which impact on sustainable devel-opment of the Russian market of animal feed; scenarios of development of domestic fodder production in the short term (2–3 years) taking into account the most pressing problems and uncertainties (distribution COVID-19; higher prices for imported feed additives; devaluation; grain yield; volatility of prices for raw materials and components, logistics, etc.); substantiation of the prospects for the development of the Russian food complex against the background of the strengthening of the global problem of hunger and food security.

The main purpose of this paper was to identify the factors affecting the selection of raw materials used by feed operators in feed production. An attempt was also made to indicate the barriers to increasing the use of native protein plants by feed operators in feed production. Today, many EU countries (including Poland) primarily rely on vegetable protein derived from genetically modified soya bean meal (mainly imported from South America and the U.S.) in addressing their needs for protein raw material used in animal feed. For many years now, Poland has taken steps to increase the production and use of native protein raw material to partially replace soya bean meal imports. The use of mixes of diverse domestic protein sources derived from grain legumes (peas, field beans, lupine) can provide an advantageous alternative to compound feeding stuff based on imported post-extraction soya bean meal. To meet the objective defined above, this paper relied on the results of a 2018 survey conducted with a sample of 29 feed operators located across the country. More than half (55%) of the enterprises surveyed did not use legumes in feed production; the use of legumes was above 10% in only 3% of respondents. When asked about the key factors affecting the selection of raw materials used in production processes, the respondents declared to be interested in buying large batches of homogeneous raw materials that meet specific quality parameters (33% replied “rather yes” and 67% replied “definitely yes”). The protein content of plant seeds used in feed production was identified as another aspect of extreme importance (55% replied “rather yes” and 24% replied “definitely yes”).

The imposition of ethanol derived from biomass for blending in gasoline would make countries less dependent on current petroleum sources, which would save foreign exchange reserves, improve rural economies and provide job opportunities in a clean and safe environment. The key drivers for successful commercial ethanol production are cheap raw materials, economic pretreatment technologies, in-house cellulase production with high and efficient titers, high ethanol fermentation rates, downstream recovery of ethanol and maximum by-products utilization. Furthermore, recent developments in engineering of biomass for increased biomass, down-regulation of lignin synthesis, improved cellulase titers and re-engineering of cellulases, and process integration of the steps involved have increased the possibility of cheap bioethanol production that competes with the price of petroleum. Recently, many companies have come forward globally for bioethanol production on a large scale. It is very clear now that bioethanol will be available at the price of fossil fuels by 2010. This article intends to provide insight and perspectives on the important recent developments in bioethanol research, the commercialization status of bioethanol production, the step-wise cost incurred in the process involved, and the possible innovations that can be utilized to reduce the cost of ethanol production.

Ukraine produces large amounts of crop residues every year, much which could be utilized to produce biofuel. However, efficient supply chains and system configurations are needed to make such systems efficient and cost effective. One option is to integrate torrefaction, power production and biofuel production into a single, coordinated system. This approach allows for high value product (i.e. biofuel), greater utilization of the energy content of the feedstock, and supply chain efficiency. Initial analyses indicate that revenues can be enhanced through this approach, and further analyses and optimization efforts could identify a sustainable approach to renewable fuel and power production for Ukraine. The question of scale and layout remains of interest as well, and a thorough logistical study is needed to identify the most suitable configuration. Agricultural operations often benefit from smaller scales of operation, whereas fuel production processes tend to operate profitably only at very large scale. Thus, a balance must be struck between the needs of both ends of the supply chain. The processing center concept helps to balance those needs. A system such as this also has potential to synergize with other agricultural production systems, such as the production of animal feed, fertilizer, and other bio-based products. The complexities of the Ukrainian agricultural market will need to be reflected carefully in any model that seeks to assess the system's potential. Presents a concept for coupling thermal pretreatment (torrefaction with biofuel and power production for the transformation of wheat straw into a value added product for Ukraine. Torrefaction provides supply chain savings, while conversion provides added value to the product. This paradigm has potential to utilize a widely produced waste material into a valuable source of energy and possibly other products for the country.

Feed is the main key to success in small and large scale catfish farming. If we keep catfish in a large scale, we must be smart to make feed management, of course. It is undeniable that many catfish farmers failed and went bankrupt because they did not know the correct technicalities in catfish farming. Where production costs in catfish cultivation are almost 70% in feed management. One alternative that can be done to reduce production costs is to make homemade feed through simple techniques by utilizing local sources of raw materials (including the utilization of agricultural industrial waste) which is relatively cheap. In addition to meeting their own needs, the artificial feed produced can also be sold to markets / other fish farmers so that it can provide multiple benefits. It is not an easy matter indeed to make fish feed itself, it requires special skills to be able to practice it themselves. Farmers must understand what content must be contained in the fish feed. In connection with this, it is deemed necessary to provide training in making their own catfish feed through simple techniques. It is also necessary to provide guidance and training that enables partners to calculate total sales revenue and total costs so that they are able to find out how much profit is earned per month. It is expected that after mentoring, partners will become more knowledgeable and able to apply it in their daily work. Thus partners will be more developed, become more economically independent, increase income, become more productive and become more optimistic in their efforts so that the entrepreneurial spirit is built.

The provision of animal feed in the form of forages or soybeans made by goat farmers in general is still traditional. Drajat Village is one of the villages where the goat breeders still use conventional methods in processing their feed. The aspect needed in small to medium scale farms is the speed of feed production time in the form of powder feed that is ready for use. To fulfill this aspect, we made goat feed chopping machines in the implementation of this Community Service Program (PKM). The animal feed chopping machine is designed with various stages including observation, consultation, science and technology diffusion, training and socialization of the use of tools. The components that are made include the engine frame, cutting knife and trajectory of entering the raw material (soybean cake). Whereas for components purchased are pulleys, V-belts, drive motors, shafts, casings and bearing bearings. From these components the assembly and manufacturing process will be carried out using tool kit equipment. The aim of this program is to provide skills training to groups of goat farmers in processing feed sources by doing mechanical processing through modernization of livestock with multipurpose animal feed counting machines, reducing the level of difficulty in animal feed search especially in the dry season and providing insight into entrepreneurship in the field of animal husbandry utilize raw materials to do the grinding process and then can be marketed to farmers in various regions. The results of this program are the achievement of a group of goat farmers who are able to produce or process animal feed independently in powder form. When animal feed ingredients are abundant, they make powder feed and store it as food self-sufficiency during the dry season.ABSTRAK Pemberian pakan ternak berupa hijauan ataupun onggok kedelai yang dilakukan oleh peternak kambing pada umumnya masih bersifat tradisional.
