The possibility of using gypsum-containing waste–citrogypsum, which is a by-product of the chemical biosynthesis of citric acid, was considered as an additive for composting poultry manure from poultry farms that practice litter-free poultry keeping. The research was carried out on an experimental batch of 1500 tons. The production of the batch was carried out by mixing citrogypsum with a moisture content of 30% and litterless chicken manure with a moisture content of no more than 80% in a ratio of 1:2. The resulting mixture was placed on an open landfill in piles 3 m wide, 1 m high and 400 m long and was mixed twice with a compost turner. Further processing consisted of mixing the mass once every seven days. The controlled parameters were changes in humidity, temperature, pH and nitrogen content during composting. In the course of the experiment, it was found that the introduction of citrogypsum into the composition of the compost helps to optimize the moisture, temperature and pH of the mixture, and a decrease in ammonia emission to 87% was recorded, with an increase in nitrogen content of 2.4 times compared to the initial value. It was concluded that citrogypsum can be used in composting poultry waste to reduce volatilization of ammonia and preserve nutrients.

Abstract New equipment set for the processing of manure, the main waste of poultry farms, into a range of ancillary products with predetermined properties and parameters is described. This technology decreases the emission of harmful substances into the atmosphere. The method of preparation of manure for the usage as a solid fuel with decreased expenses for drying was developed; this method allows for the significant decrease of nitrogen content in the manure (resulting in the decreased nitrogen emission at burning). The method involves the preliminary mixing of the manure with a natural absorbent (3-5% of the dry matter of manure) sieved through the 0.2 mm screen; separation of the mixture (by centrifuging or pressing) to solid fraction (moisture content 45-56%) and liquid fraction; drying of the solid fraction in a cylinder drier to moisture content 12-22%; the final product can also be pelleted. A part of the product can be burned in a furnace to produce the heat for the drying of the solid fraction; liquid fraction can be further processed in a coagulator to extract protein or can be used as a liquid fertilizer or ingredient of the liquid substrates in the hydroponic greenhouses.

SUMMARYDried poultry waste was substituted for soya and fish meals in an intensive beef ration to ascertain if it was a satisfactory alternative source of nitrogen and in an attempt to reduce the cost of production. The experiment was conducted over 3 years in each of which groups of autumn-born British Friesian male castrates were taken from 150 kg live weight to slaughter at 400 kg on various rations. The treatment rations were made isonitrogenous with the control (14·5% crude protein). When the crude protein of the poultry manure was low (24%) it was necessary to include 27·6% in the diet and poor performances resulted. For manures of 30 % crude protein, or when urea was added to equalize the nitrogen content of diets containing up to 17·5% manure, performance was not markedly different from that shown with control diets. There was a considerable saving in the food cost at the prices ruling when the experiment was conducted and it was concluded that the use of dried poultry manure could increase the profitability of intensively produced beef.

Manure Poultry: Alternative Feed Supplements and Impacts on the EnvironmentABSTRACTThe increase in protein demand is now of serious concern as the human population is forecasted to rise to as much as 9.6 billion by 2050. The poultry industry is one of the largest and fastest growing sectors of livestock production in the world. Increased production results in increased sewage so that the impact on the emergence of environmental problems associated with increased air pollution, water, and soil. The sustainability of animal feeds is crucial in the development of livestock production systems, and feed efficiency can be improved by reusing poultry waste in livestock diets, thus diminishing the use of feed grains. There are several ways of disposing of poultry waste including burial, incineration, composting, fertilizer or source of biogas energy and feed for livestock. Poultry manure is a rich source of lignocelluloses, polysaccharides, proteins, minerals, and other biological materials. It is currently expected some problems can be overcome by utilizing poultry manure waste as an alternative feed source for livestock. This paper aims to review the negative effects of excessive chicken manure and its benefits as an alternative feed for livestock and fish.Keywords: alternative feed, livestock, pollution, poultry industry, poultry manure ABSTRAKKenaikan permintaan protein menjadi perhatian serius karena populasi manusia diperkirakan akan meningkat menjadi sebanyak 9,6 miliar orang pada tahun 2050.

In the UK the poultry industry has a good record with regard to surface water contamination and has been responsible for only a small proportion of the total pollution incidents attributable to agriculture. Guidance is provided to farmers by a Code of Good Agricultural Practice for the Protection of Water. Because poultry manures have high concentrations of total nitrogen, with much of this in soluble form, the pollution of ground water with nitrates is a more serious problem. A voluntary Pilot Nitrate Scheme has been introduced in some parts of the UK which controls the quantities of animal waste applied to the land and also the timing of waste application. Linked to the scheme is a comprehensive programme of scientific monitoring. The broad requirements of the European Community Nitrate Directive are described. In the case of air pollution due to odours, poultry farms were reported to be responsible for 17% of complaints attributed to agriculture. Where appropriate, legislative means exist to reduce the nuisance and a Code of Good Agricultural Practice for the Protection of Air has been published. Some implications for poultry production in the future are considered.

Animal manures have been used as natural crop fertilizers for centuries. Because of poultry manure’s high nitrogen content, it has long been recognized as one of the most desirable manures. Besides fertilizing crops, manures also supply other essential plant nutrients and serve as a soil amendment by adding organic matter, which helps improve the soil’s moisture and nutrient retention. Organic matter persistence will vary with temperature, drainage, rainfall, and other environmental factors. This 2-page fact sheet was written by Michael A. Davis, D.R. Sloan, Gerald Kidder, and R.D. Jacobs, and published by the UF Department of Animal Science, November 2013. http://edis.ifas.ufl.edu/aa205

The objective of this work was to optimize the bioprocess parameters, using Klebsiella oxytoca ICCF 419 to obtain an exopolysaccharide based on lactose as substrate. A kinetic study was employed and Logistic and Gompertz models were applied to describe the polysaccharide production, in relation with biomass growth and substrate consumption. The RSM methodology based on Central Composite Rotatable Design was used to evaluate and optimize the effect of lactose, corn extract, KH2PO4 and citric acid concentrations as independent variables on the polysaccharide production, biomass growth and substrate consumption as the response functions. The interaction effects and optimal parameters were obtained using Design Expert Software (version 9.0.6.2). The significance of the variables and their interactions was tested by means of ANOVA analysis with a 99% confidence level. The optimum culture conditions were determined and the model prediction was compared with experimental results. At an initial value of 23.45 for the C/N in the fermentation medium, the strain produces 17.41 g/L of crude polysaccharide and 2.53 g/L dry biomass. The EPS production was significantly influenced by lactose, corn extract and KH2PO4, while the citric acid had no influence. The biomass growth was influenced by the corn extract, KH2PO4 and citric acid.

The aim of the work was to develop the parameters of the process of salting Pacific herring fillet with a reduced salt content, intended for children’s nutrition. For salting, food salt with a reduced sodium content, enriched with potassium, magnesium, was used. Based on the conducted studies, a rational formulation of the salting mixture was selected, consisting of 5 % salt with a reduced sodium content, 4% sugar, 0.35-0.50% citric acid. It was found that carrying out the salting process for 72-96 hours provides a low-salted fillet with a salt content of 3.5% with high organoleptic parameters, which are determined by the amino nitrogen content of 110-130 mg/100 g of the product and the buffering capacities of 40-45 degrees.
