Abstract:
The article highlights different technologies of aviculture wastes recycling, first of all feather raw materials, for fodder purposes, in particular hydrothermal method, extrusion method, thermochemical method, and method of high temperature and high pressure. Hydrothermal method of recycling of meat and bone wastes in the horizontal vacuum boilers has quite satisfactory results, but ineffective in the processing of feather raw materials. More effective methods of raw feathers processing are ones with the use of extrusion process and thermochemical machining, but due to the complexity of processes, large amount of outlay and unsatisfactory sanitary and environmental conditions these technologies are not widely used in manufacturing. European experience of non-waste production and processing of aviculture wastes deserves deeper studying, particularly recycling of raw feathers, by processing method with high temperature and high pressure at continuous technological process and the possibility of using these technologies in the domestic large-scale production at poultry farms of industrial type. The purpose of the work was to study domestic and foreign advanced technologies of processing of non-food wastes of poultry products and production of high-protein feed additives and to consider the widespread introduction of the most effective ones in domestic manufacture on an industrial scale. The main wastes of processing of poultry products are gastrointestinal tract and its content, bone frame in the case of deep processing of carcasses, heads, legs, and other expired products, blood and, above all, feather raw materials, which totally constitute 20% of poultry weight. Recycling of meat and bone wastes from poultry slaughtering is carried out in horizontal vacuum boilers (so called Laps boilers), which are mainly used for animal origin wastes at sanitary-veterinary factories, united in association "Ukrvetsanzavod." The vacuum horizontal boiler for the production of fodder flour from animal raw materials wastes at the sanitary-veterinary utilization factories is a cylindrical metal frame located on stilts, which has a loading manhole and unloading pipes and on the outside of a cylindrical frame – a shell for heating of the frame with pipes for filing and withdrawal of the heat carrier and shaft, which is mounted along the length of the frame, with a mixer, fixed on the ends by bearings. Hot steam is the heat carrier for temperature processing of raw materials, which is supplied directly from the boiler room into the frame shell. In order to improve horizontal vacuum boiler for producing fodder flour from animal raw material wastes and to reduce its prime cost the special device was designed for its heating by using electricity. To do this on the outside of boiler (for its heating) there is a bullet made of the refractory material with three electric heaters, covered with a layer of insulation. In our country animal origin feed production has recently decreased, and the price of imported fodder is extremely high due to the reduction in livestock numbers and their processing. At the same time, Ukraine has gained intensive development of the poultry industry, particularly growing the broiler chickens and processing their meat at the large poultry farms of industrial type. Herewith, the substantial amount of non-food wastes from poultry products processing (gastrointestinal tract, bone frame in the case of deep processing of carcasses, dead poultry, blood, feather raw materials etc.) is not used for fodder purposes in many poultry farms. Furthermore, in order to get rid of wastes from poultry and livestock products processing, and instead of organizing high protein feed additives production from them, the technologies of destruction them by burning are developed, which can’t be considered reasonable solution to this problem. It is not only the reason of significant losses of valuable high-protein raw material for animal origin fodder, but also leads to environmental pollution. Therefore, in the conditions of a shortage of animal origin fodder, the use of non-food poultry products processing wastes is not only a great resource saving value, but simultaneously solves some environmental problems.

Abstract:
This paper provides an overview of methods for processing and recycling chicken droppings. Poultry farms are a source of litter formation in an amount much larger than the main products. The litter contains up to 80% organic matter, many trace elements, all essential amino acids, growth regulators, vitamins, nitrogen and phosphorus. According to the Federal waste catalog, fresh chicken droppings belong to the 3rd hazard class. Fresh dung contains a significant amount of weed seeds, helminth eggs and pathogenic microorganisms. Dung is a source of toxic gases-ammonia, hydrogen sulfide, methane, carbon monoxide. Without recycling, manure becomes a source of environmental pollution. Disposal of chicken droppings is a difficult issue for many farms. Modern trends in the processing and use of poultry manure: 1) direct application to the soil without additional treatment, 2) Processing by passive and active composting, 3) Vermicomposting, 4) Processing with the help of housefly larvae, 5) Dehydration and drying (mechanical, thermal, vacuum), 6) Pyrolysis at t = 450-550 °C, 7) Plasma gasification, 8) thermal depolymerization Technology, 9) Direct combustion in steam and hot water boilers, 10) Microbiological conversion, 11) anaerobic digestion in Methane tanks with the formation of biogas, 12) Dung as a component of compound feed for cattle. The considered technologies of utilization of bird droppings do not fully contribute to the preservation of the environment and production. At the present stage, the industry needs an environmentally friendly and cost-effective biotechnology for processing manure, which makes it possible to turn organic waste into valuable raw materials for obtaining feed, fuels, fertilizers, and substrates for the chemical and microbiological industries. The future of waste management is in nature-like technologies, because in nature, all the necessary processing mechanisms are already in place.

Abstract:
Poultry production at all levels appears to be lucrative and profitable but many factors appear to limit the involvement of rural dwellers in this sector. This study was carried out at Oluyole Local Government Area Oyo State to assess the level of involvement of rural dwellers in small scale poultry farming. Some parts of Oluyole local government were purposely selected for this study because of higher concentration of rural dwellers that are involved in poultry production. A total of ninety five respondents were sampled and had a well-structured questionnaire administered to them to determine their socio economics characteristic, their level of involvement, benefit derived and constraint faced in poultry farming. Data were analyzed using descriptive statistics of frequency counts, percentage and means, Chi-square and Pearson Product Moment Correlation (PPMC) at 0.05% level of significance. The results show that majority of the respondents were males (61.1%), married (68.8%) and have tertiary education (59.1%). Majority (50.5%) of the respondents were between the ages of 31-45years. Socio-economic characteristics such as age, region, sex, educational level, household size and income had no significant relationship with the respondent’s level of involvement in small scale poultry farming (P<0.05). Results on level of involvement shows that most (48.8%) of the sampled correspondents were involved in boilers production. The study also shows that the benefit derived in poultry farming remained the same regardless of the level of involvement of the farmers in various poultry activities, with r –value (0.177), p-value (0.089) indicating that the relationship is not significant (P<0.01), it also indicated that the relationship between the constraints facing the respondents and their level of involvement is not significant with r –value (0.154). Also, the major constraints facing the respondents included difficulty in accessing loan and quality feed. Government should therefore make loan facilities at affordable interest rate while all the stake holders should work together to improve farmers’ access to quality feed, vaccine, technical know-how and adequate extension workers.

Abstract:
Thermophilic Campylobacter are among the most common cause of bacterial enteritis in humans. Food animals are considered one of the most important sources of Campylobacter causing infections in man. Campylobacter infection is clinically mild and resolves spontaneously. In severe or long-lasting cases, treatment with antibiotics is necessary. Resistance of Campylobacter spp. to drugs used in treatment of infection is a matter of concern. The aim of this paper is to determine presence of multi drug resistant strains of Campylobacter jejuni and Campylobacter coli isolated from animals and man. Material for testing was obtained by scraping the cecum surface from boilers, pig cecum and colon, and human feces. For isolation Campylobacter jejuni and Campylobacter coli microaerophilic conditions, temperature of 42?C and antibiotic supplement were required to inhibit the growth of other intestinal bacteria. In this research, for sensitivity testing of Campylobacter jejuni and Campylobacter coli three different methods were used: disc diffusion test, E-test, and dilution agar method. A total of 55 strains of Campylobacter jejuni and Campylobacter coli. Out of the total, 24 strains originated from man, 16 from broilers were isolated, and 15 from pigs. Multidrug resistance was determined in cases when the strains were resistant to two or more antibiotics. Applying E-test, we detected that the largest number of Campylobacter jejuni were multi drug resistant to two antibiotics (41.2%), and three antibiotics (11.8%). Applying disc diffusion method it was detected that 5.9% of Campylobacter jejuni from man was resistant to four tested antibiotics. Applying all three methods, it was detected that the largest number of Campylobacter strains was resistant to two antibiotics and three antibiotics. Applying disc diffusion method it was detected that 50% of Campylobacter coli strains from pigs were resistant to three tested antibiotics.

Abstract:
The urgency of solving the problem of heat losses on heating mains and сentral boiler houses in poultry houses is important, since the efforts of poultry farms are focused on improving the devices and heating systems in the poultry houses themselves. One of the directions of the solution of this problem is the use of exclusive qualities of infrared heating in the variant where its specific advantages of selective heating of a given object are revealed as much as possible, excluding intermediate heat carriers. Thus, the calculation of the relationship of dark infrУared heating systems in addition to traditional microclimatic systems in poultry farms from different regions of the Russian Federation has shown high efficiency in the operation of this design.

Abstract:
Nitrate, nitrite and nitrosamines were analysed in poultry feeds, meat and eggs. The poultry meat was boiled and roasted while the eggs were raw and boiled, and the effects of these processing treatments on the level of these compounds were investigated. Nitrate levels in the meat samples were significantly (P < 0.05) reduced by boiling and roasting, with boiling being more effective. Nitrite levels were also reduced significantly by processing (P < 0.05). The feed samples contained levels of nitrate which were significantly different (P < 0.05) from one producer to another. Nitrite levels were generally low in all feed samples. Nitrosamines were not detected in any of the feed samples and in the meat samples except in two samples of boiled meat which contained 0.001 g/kg each.

Abstract:
Combustion of pure avian waste is strongly affected by its humidity content. According to the results of composition analysis, the initial humidity reaches up to 50%, inhibiting direct combustion initiation and development. Drying of poultry waste is an alternative, but simple relatively long-term storage or thermal pre-processing, complicates the technological process of energy recovery and increases the associated costs. Co-combustion represents a promising solution to enrich the heating value of raw poultry manure. Experiments using biomass (in a mass fraction of up to 30%) led to positive results in terms of efficiency. It is highlighted that the process depends on the quality of the woody biomass used for the mixture, but also on its bulk density, which causes an accelerated diffusion of air and influences the burning speed. This paper presents the experimental investigations on the co-combustion of poultry manure and woody biomass, performed on a 55 kW pilot boiler equipped with a post-combustion grate. The focus of the analysis is on the influence of the biomass bulk density and its heating value on the co-combustion process. The results obtained favor the development of a technology that is easy to apply and has a reduced cost. The technology investigated here is suitable for onsite applications in poultry farms, enabling meeting the energy demand based on co-combustion of resulting poultry waste.

Abstract:
This study aims was to determine the effect of different types of poultry meat on organoleptics quality of abon. As much as 500 grams of breast meat from three types of poultry (Arabian chicken, Manila duck and pigeon) are made into abon. Boiled meat, torn to lenght, mixed evenly with spices then boiled until cooked. Add the coconut milk, cooked on low fire while stirred until the coconut milk dries, then fries using oil over low fire for 10-15 minutes, then drained to remove the oil. The abon is served in 3 different places, then tested organoleptic (color, aroma, texture, taste and preference) by 15 untrained panelists. The data obtained were analyzed by variance for complete randomized design. The results showed that the use of different poultry meat had a significant on color (P<0.01) and texture (P<0.05) of abon. The abon of pigeon meat tend to be brown, compared to abon of Arabic chicken and Manila ducks. The abon of Arabic chicken meat, the texture tends to be smooth, compared to the abon of Manila duck and pigeons. It can be concluded that for color, abon of pigeon meat is better, while for texture, abon of Arabic chicken meat is better.

Abstract:
This investigation was conducted in the rural community of Cuambo, located in the northeast of the province of Imbabura, in the Mira river basin of Salinas parish, at 1530 meters above sea level and with an average temperature of 19.5° C. The main objective of this investigation was to analyze the effect of using amaranth (Amaranthus) leaf flour in the creation of feeds for broiler chickens. The field work occurred during 12 months and consisted of two phases: A. Creation of the feed: This proceeded from the cultivation, cutting, and drying of amaranth until the obtaining of the flour and later the feed, with the respective formulation and acquisition of primary materials. B. Broiler chicken production: This occurred in the coop of the community's school, previously prepared for taking in the chicks. The study lasted 8 weeks. A completely random design (CRD) with five treatments and four repetitions per treatment was used, with 10 chickens per experimental unit. ANOVA analysis and Tukey and orthogonal comparisons were applied. The factor under study was the percentage of amaranth leaf flour in a basic diet. The treatments were as follows: T0 = Control diet for broiler chickens T1 = 16.7% amaranth leaf flour T2 = 35% amaranth leaf flour T3 = 54% amaranth leaf flour T4 = 78% amaranth leaf flour Analyzed variables: Weekly weight increase, Weekly food conversion, Accumulated food conversion, Total food consumption, Efficiency index, Yield, Skin pigmentation at the end of the treatments, Organoleptic analysis, Mortality, Economic analysis. From the results obtained, we conclude that the feed from treatment 1 (T1) is the best because it gave the most efficient results in terms of weight increase, food conversion, efficiency index, yield, and production cost. In the organoleptic analysis, T2 received more points regarding appearance, color, and texture; T1 received the best points in odor. The most acceptable treatments are T2 and T1, with the most points. In production cost, T4 was the least expensive, but it is not recommended for use because the chickens had poor results in the studied variables.

Abstract:
The state of Maryland issued a Request for Proposal to solicit exportable electrical power using locally sourced poultry littler as the primary fuel. The overall goal was to promote the use of renewable energy and reduce agricultural runoff to Chesapeake Bay. POWER Engineers (POWER) was brought on to the project team by the selected development contractor to provide a preliminary level design and high level cost estimate for the feasibility study and technology investigation. POWER’s scope included: • Preliminary engineering for boiler technology selection and sizing • Selection of fuel handling equipment and logistics • Providing an air emissions estimate • Water quality and demand requirements • Developing an engineering and construction cost estimate POWER determined that to produce 20.4 MW of electricity and process steam, it would take roughly 60 truckloads of 100% poultry litter waste-per-day to run the plant. The bubbling fluidized bed boiler technology developed by ANDRITZ for biomass applications and fully automated fuel handling system would make this biomass plant the first-of-its-kind in the United States. POWER’s team was able to reach out into new and different areas of technology and take a new approach to biomass facility design.
