In our study, we monitored the inactivation of two important viruses that are critical in animal husbandry throughout the world. To evaluate the influence of the composting process on inactivation of avian influenza virus (H9N2) in poultry manure compost (PMC) and Encephalomyocarditis virus (EMCV) in pig (swine) manure compost (SMC), the H9N2 and EMCV were injected in dialysis cassettes and buried in two different manure compost piles of poultry and pig manure, respectively. The highest temperature achieved in the PMC and SMC piles during the test period were 75 °C and 73.5 °C, respectively. At the completion of the composting for 168 h, inactivation effect appeared to be more sensitive in H9N2 than EMCV. The vitality of H9N2 decreased by 6.25 ± 0.35 log10TCID50/mL to 0.0 log10TCID50/mL within 1 h of the composting. The vitality of EMCV decreased from 7.75 ± 0.35 log10TCID50/mL to 1.50 log10TCID50/mL within 24 h of starting the composting process. However, the activation of EMCV was not decreased (from 7.75 ± 0.35 to 7.50 ± 0.71 log10TCID50/mL) in the control treatment (not inserted in composts) after 168h, while the activation of H9N2 in dialysis cassettes was significantly decreased (from 6.25 ± 0.35 log10TCID50/mL to 2.00 ± 0.6 log10TCID50/mL). Our study demonstrated the effectiveness of the composting treatment in inactivating the viruses studied, which was not the case with air treatment.

The global demand for protein led to the increase of animal production in the world and, mainly, in Brazil. As a consequence, there was an increase in the amount of waste produced, and the need to seek alternatives for its sustainable use. Microbial indicators and multivariate tools can assist in the proper measurement of the impact of the use of this waste on the soil. This study aimed to: 1) measure the effect of the application of organic fertilizers of animal origin in the no-tillage system on soil microbial attributes and its relationship with maize yield; 2) evaluate the potential of separation/discrimination of the different sources of organic fertilizers based on yield and soil microbial and chemical-physical attributes, using multivariate tools. Treatments consisted of annual application of: poultry manure (PM), liquid swine manure (LSM), poultry manure compost (PMC), swine manure compost (SMC), cattle manure compost (CMC) and control (C), without fertilization. Organic fertilizers promoted higher values of microbial biomass (MB) and MBC:TOC ratio in treatments CMC, SMC and PM in the first sampling season (E1), followed by PM, LSM and PMC in the second sampling period (E2). The data show that PM promoted microbial growth in both seasons, with higher metabolic efficiency increasing maize yield by 30% in relation to the treatment with the second highest production, PMC. Multivariate analysis techniques prove to be important tools to study soil quality indicators in systems which use organic fertilizers.

This research aimed to evaluate the efficiency of the treatment of manure from three livestock production units (cattle, swine, and poultry), through composting with mechanized turning and incorporation of natural substrate (wood sawdust) in rural properties in the municipalities of Farroupilha, Relvado, and Caxias do Sul, State of Rio Grande do Sul, Brazil. The experimental design consisted of nine treatments, three for each type of manure. These were classified as: T1 (cattle manure plus wood sawdust), T2 (swine manure plus wood sawdust), and T3 (poultry manure plus wood sawdust). The process involved the daily turning of the windrows by a mechanized process and sampling was carried out in triplicate at 60, 120, and 180 days of composting, between the months of July 2018 and July 2019. After each sampling, samples were properly stored and sent to the Chemistry Laboratory of the University of Santa Cruz do Sul for analysis of the following variables: Calcium (Ca), Cation Exchange Capacity (CTC), Phosphorus (P), Magnesium (Mg), Nitrogen (N), pH, and Potassium (K). Temperature measurements were made on the spot every 15 days. At the end of the experiment, all treatments reached the standards of humidity, temperature, pH, and NPK, established in Normative Instruction No. 25/200 for organic fertilizers, from the Ministry of Agriculture and Livestock of Brazil. Thus, the results demonstrated the efficiency of the mechanized composting process for the treatment of bovine, swine, and poultry manure, producing a high-quality organic compost.

Background:The increased energy consumption from fossil fuels with its attendant gas emissions and environmental problems has provided the impetus to exploit new energy source that are renewable and environmentally-friendly.Objective:This work focused on the investigation and evaluation of the single or individual effects of feed-inoculum ratio, temperature, and agitation speed (i.e.operating variables) on biomethanization of the mixture of cattle manure, pig manure and poultry manure (mixed animal wastes) co-digested with pineapple fruit waste and content of chicken-gizzard (inoculum) as well as to model the kinetics of biomethanization at these different operating variables and to determine the thermodynamic properties of the biomethanization process.Method:The biomethanization experiments were carried out in anaerobic biodigesters at operating variables of feed/inoculums ratio that ranged from 1:1 to 3:1, temperature from 25 to 60°C, and agitation speed from 30 - 70 rpm using one factor at a time (OFAT) method. The biodigesters were incubated for 70 days retention time.Result:The feed/inoculum ratio, temperature and agitation speed had positive impact on cumulative biogas yield, biomethane content and start-up time of biomethanization. The cumulative biogas yield and biomethane content achieved with agitation speed of 30 to 70 rpm was respectively higher than the biogas yield and biomethane content attained without agitation. Minimum cumulative biogas yield and biomethane content was respectively obtained with feed/inoculum ratio of 1:1, temperature of 25°C and agitation speed of 70 rpm; while maximum cumulative biogas yield with its biomethane content was attained with feed/inoculum ratios of 1:3 and 3:1, temperature of 60°C and agitation speed of 30 rpm, respectively. Modified Gompertz and Exponential Rise to Maximum kinetic models fitted very well to the data and thus showed better correlation of cumulative biogas production. The thermodynamic parameters of Gibbs free energy, enthalpy, entropy change and activation energy of biomethanization were estimated and evaluated, and was found that the biomethanization process was thermodynamically feasible, spontaneous and endothermic in nature suggesting hydrogenotrophic methanogenesis pathway. The activation energy of the biomethanization process was found to be 3.324 kJ/ mol. The specific heat capacity at constant volume and constant pressure, specific internal energy and specific enthalpy of the biogas and biomethane content increased with increase in temperature.Conclusion:Biogas/biomethane production from the biomethanization of mixed animal wastes co-digested with fruit waste and inoculum is a feasible, viable and sustainable renewable energy option that can be simulated by kinetic models and influenced by operating variables.

The widespread raising of swine in farms becomes a serious problem in terms of the emission of carbon dioxide (CO2) and methane (CH4). This study aims to measure concentrations of carbon dioxide and methane, which account for the largest percentage of carbon emissions, to temporally estimate the carbon emitted during the pig-manure composting process. The research subject was a farmhouse raising 3000 growing pigs and 100 mother pigs. The capacity of the composting facility for pig manure treatment was 330 m2, and the daily treatment was about 6 tons. After the pig manure discharged from the pig farm was delivered to the composting facility, for the 8 days including 6 before mixing and 2 after mixing, the concentrations of CO2 and CH4 were measured. The result shows that the CO2 and CH4 concentrations in the composting facility were 1208 ± 385 ppm and 95 ± 10 ppm, respectively. In the comparison of concentrations before and after mixing at the composting facility, the values of both CO2 and CH4 increased, and the temperature increased as well. The concentration of CO2 and CH4 increased to 499 ± 103 ppm and 3 ± 11 ppm, respectively, and the temperature rose by 3.7 ± 1.0 °C and 1.6 ± 2.4 °C, respectively. In the correlation analysis (r = 0, p < 0.05), the carbon dioxide emission in the composting process was 15.564 ± 3.671 tons C/year, whereas carbon emission was 1.379 ± 0.147 tons C/year. The concentrations of CO2 and methane, which are the current major atmospheric pollution sources, were respectively analyzed during the pig-manure composting process in this study to understand their effects. Thus, this paper attempts to elucidate the carbon cycle by measuring and analyzing the carbon data obtained from livestock excretions to secure a supply chain based on the intelligent use of the data.

<p class="1Body">Two field experiments were conducted from 2012 to 2013 cropping seasons to evaluate the efficacy and also determine the optimum rates of application for fish pond waste water in comparison with three other manures including one inorganic fertilizer and two organic manures under garden egg (<em>Solanum spp.</em>) crop.Garden egg was fertilized with pond waste water (PW), poultry manure (PM), pig manure (PG) and NPK15:15:15 at equivalent nitrogen (N) rates (0, 150, 300, 450 kg/ha). The treatments were arranged in a split plot under randomized complete block design (RCBD).The results obtained indicated a slight drop in soil pH but soil OM, total N, available P, exchangeable Ca and K increased generally with increasing rates of manures. The PW and PG treatments supported significantly (P&lt;0.05) the highest yields of the crop compared to PM and NPK with the 150 and 300 kg/ha treatments recording the highest increase. These results have shown that under the high rainfall and acidic soil conditions of Akwa Ibom State in Nigeria, PW is useful for the improvement of soil conditions and achievement of higher crop yields when applied at rates that supply N in the range of 150 – 300 kg/ha.</p>

E-mail: [email protected].  1 RESUMO Pouco se conhece sobre a dinâmica da solução do solo em resposta a aplicação de diferentes fertilizantes no solo, principalmente, em relação à adubação fosfatada. Nesse sentido, avaliou-se o teor de fósforo, pH e condutividade elétrica na solução do solo e, a produção de biomassa de parte aérea de plantas em resposta a aplicação de fertilizantes fluidos mineral e organomineral a base de dejeto suíno e, mineral sólido. Os tratamentos foram: testemunha geral caracterizada pela ausência de nutrientes, testemunha de fósforo (P) caracterizada pela ausência apenas de P, fertilizantes fluido mineral (MF-P) e organomineral (OF-P) e, sólido (MS-P) aplicados em Latossolo Vermelho distroférrico (LV) e Neossolo Quartzarênico Órtico típico (NQ). O experimento foi conduzido em vasos em casa de vegetação em delineamento experimental de blocos casualizados com quatro repetições. A solução do solo foi captada através de extratores de solução instalados nos vasos, realizando-se dez coletas no período de 137 dias após a aplicação dos fertilizantes, abrangendo dois cultivos consecutivos de aveia preta (cultivo I e cultivo II). Em ambos os solos o rendimento de matéria seca no cultivo I foi maior no OF-P e no cultivo II semelhante no MS-P, MF-P e OF-P, sendo os maiores rendimentos demonstrados no LV em relação ao NQ. Os teores de P na solução do solo variaram ao longo do tempo apenas no OF-P no LV, enquanto que no NQ houve variação em todos os tratamentos, sendo em ambos os solos os maiores teores a partir do cultivo II.  Para os valores de pH e condutividade elétrica (CE) também houve variação ao longo do tempo em ambos os solos, sendo que no pH os valores aumentaram e na CE os valores diminuíram no cultivo II em relação ao cultivo I em todos os tratamentos. Palavras-chave: adubo líquido e sólido, resíduo, esterco.   FERNADES, D.

The experiment was carried out   using pots in a greenhouse with a randomized block  experimental design  and  four replicates. Soil solution was collected by solution extractors installed in pots. Ten collections were performed over 137 days after fertilizer application, which included two crops in a row of black oat (cultivation I and cultivation II). In both soils, yield of dry matter in cultivation I was higher in OF-P, and  it was similar in  (SM-P), (MF-P) and (OF-P) in cultivation II. Higher yield was obtained in LVd in relation to TQ.  Phosphorus content in soil solution ranged over time just in OF-P in LVd, whereas  variation was observed in all treatments in TQ. In both soils, higher content was observed as of cultivation II.   Also, variation over time was observed for pH and electrical conductivity (EC) values in both soils. Values of pH increased and values of EC decreased in cultivation II as compared with those in cultivation I in all treatments. Keywords: liquid and solid fertilizer, residue, manure.

Background and Aim: Using antimicrobials as a feed additive in swine production is prohibited because it is a major cause of the emergence of antimicrobial-resistant bacteria. Probiotics such as Lactobacillus spp. are an attractive alternative to reduce antimicrobial resistance and promote swine growth. This study aimed to evaluate the in vitro probiotic properties of Lactobacillus isolated from indigenous swine manure. Materials and Methods: A total of 30 fecal samples from healthy individual indigenous pigs were collected and isolated on de Man, Rogosa, and Sharpe agar. The preliminary screen identified candidates with antibacterial activity against six pathogens and >50% survival and tolerance to acid (pH 3.0) and 1% bile salt. Isolates that passed the initial screen will be tested for other probiotic properties. Results: Of the 314 isolates from 30 pig manure samples, 17 isolates satisfied all initial conditions for probiotic properties. Each isolate has unique, distinctive properties. Isolates B4, B5, B8, B17, B87, and B144 formed thick biofilms, whereas isolates B5, B8, and 27 adhered well to the intestinal wall and exhibited strong autoaggregation properties. Isolate B4 aggregated with Enterohemorrhagic Escherichia coli and Enteropathogenic E. coli. Tests in pH-adjusted cell-free medium indicated that the antibacterial activity resulted from bacterial acidification rather than bacteriocin formation. Sequence analysis (16S rRNA) revealed 16 of the isolates were Lactobacillus plantarum, and only one isolate was Lactobacillus salivarius. Conclusion: We isolated 17 Lactobacillus from swine manure and demonstrated that their probiotic properties might be useful as a probiotic cocktail for swine feed.

Nitrous oxide (N2O) is one of the main gases that contributes to the greenhouse effect. With a Global Warming Potential (GWP) 265 times greater than that of carbon dioxide (CO2), over a 100-year horizon, N2O also has the potential for the depreciation of the ozone layer. The activities related to agriculture and livestock are responsible for approximately 60% of the global anthropogenic emissions of this gas to the atmosphere. In Brazil, the sector corresponds to 37% of total emissions. The objectives of this review article were: (i) To verify which are the main processes involved in N2O emissions in soils fertilized with swine manure; (ii) What are the direct emissions on these soils under different management systems, and; (iii) What are the possible strategies for controlling and mitigating N2O emissions. Therefore, an exploratory and qualitative research of articles was carried out using the following keywords: óxido nitroso’, ‘nitrous oxide’, ‘N2O’, ‘nitrogênio’, ‘nitrogen’, ‘suínos, ‘pig, ‘swine’, ‘dejetos’, ‘manure’ and ‘slurry’. Effects of pig diet, manure treatment systems, presence of heavy metals in the soil and moisture content of manure on N2O emissions were verified. Therefore, we recommend integrated studies of the quantitative and qualitative impacts of the levels and sources of nitrogen in the animals' diets on N2O emissions after the application of these wastes to the soil. We also recommend studies related to the effects of copper and zinc contents added to the soil via swine manure on enzymes that catalyze the biotic denitrification process in the soil.
