ABSTRACT. This research evaluated the effects of diets containing or not containing deactivated soybean sums on productive performance, carcass attributes, carcass ultrasound, and feed cost in confined heifers with 1/2 Nellore-Angus blood. We used blood from 60 1/2 Nellore-Angus heifers aged 2 or 25 years with a body weight of 404.62 kg. A completely randomized design was used, in which the animals were divided into 2 experimental groups: Cont (concentrated for semi feedlot without added deactivated soybean) and Bocchi (concentrated for semi feedlot with the addition of deactivated soybeans). There was no significant difference in the final weight between the experimental groups or for the consumption of concentrate in the evaluation periods. However, heifers supplemented with deactivated soybean in the diet showed greater daily weight gain than did those in the Cont group, as well as greater carcass weight, arrobas gain, and carcass yield. Bocchi concentrate was less expensive than Cont (U$ 7.26 ton-1). The addition of deactivated soybean for finishing cattle is indicated because it provided the animals with higher energy intake and positively influenced the productive performance as a final weight gain greater than that of the feed without adding the deactivated soybean in addition to lower production cost.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

RESUMO Os objetivos desta pesquisa foram avaliar os efeitos do probiótico e da quitosana como aditivos alimentares na qualidade e composição da carne de 36 coelhos da raça Nova Zelândia Branco (57±8 dias de idade e 1.648±0.194 kg) e no perfil de ácidos graxos dos cecotrofos. Os tratamentos foram CT (dietas sem inclusão de aditivos), PRO (inclusão de 4 g/kg de probiótico) e CHI (inclusão de 4 g/kg de quitosana). Os aditivos aumentaram os triglicerídeos e diminuíram a ureia em comparação ao grupo controle, bem como amentaram os ácidos oleico e linoleico, Ʃ insaturados, Ʃ monoinsaturados e Ʃ poli-insaturados nos cecotrofos. Os animais CHI apresentaram diminuição nos ácidos mirístico e palmítico em comparação ao PRO. A CHI diminuiu a proteína bruta da carne e o extrato etéreo da carne. Além disso, houve uma diminuição no ômega-3, ômega-6 e a relação entre ácidos graxos insaturados e saturados para o grupo CHI e aumento do ácido erúcico e diminuição do índice de hipocolesterolemia. Como conclusão, os dados mostraram que os animais que ingeriram probiótico apresentaram melhor qualidade da carne, por apresentarem melhores perfil de ácidos graxos e índice hipocolesterolêmico, em comparação ao tratamento com quitosana. Os aditivos melhoraram o perfil de ácidos graxos dos cecotrofos.

ABSTRACT The objectives of this research were to evaluate the effects of commercial probiotic and chitosan as food additives on the quality and meat composition of 36 New Zealand White rabbits (57 ± 8 days old and 1,648 ± 0.194 kg) and on the fatty acid profile of caecotrophs. The treatments were CT (diets without inclusion of additives), PRO (inclusion of 4 g / kg of commercial probiotic) and CHI (inclusion of 4 g / kg of chitosan). The additives increased triglycerides and decreased urea compared to the control group, as well as increased oleic and linoleic acids, Ʃ unsaturated, Ʃ monounsaturated and Ʃ polyunsaturated in caecotrophs. CHI animals showed a decrease in myristic and palmitic acids compared to PRO. CHI decreased the meat's crude protein and the meat's fat. In addition, there was a decrease in omega-3, omega-6 and the relationship unsaturated and saturated fatty acids for the CHI group and an increase in erucic acid and a decrease in the rate of hypocholesterolemic acids. As a conclusion, the data showed that the animals that ingested probiotic had better meat quality, for having better fatty acid profile and hypocholesterolemic index, compared to the treatment with chitosan. The additives improved the caecotrophs fatty acid profile.

RESUMO. Este estudo foi realizado para avaliar o desempenho de cordeiros em confinamento recebendo dietas formuladas com fenos de diferentes genótipos de Cynodon spp. Ainda, comparar a digestibilidade da matéria seca das dietas usando diferentes métodos de avaliação (coleta total de fezes e óxido crômico). Foram utilizados 30 cordeiros, machos, não castrados, mestiços Suffolk, com média de idade de 90 dias e peso corporal médio de 21,5 kg ± 1,6. As dietas foram formuladas utilizando um concentrado padrão e feno dos seguintes genótipos de Cynodon dactylon: Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 e Russel, em uma razão volumoso concentrado de 60:40, constituindo os tratamentos, distribuídos em delineamento em blocos casualizados em esquema fatorial 5 x 2, sendo 5 dietas e 2 métodos de avaliação de digestibilidade. Os animais que receberam feno do Vaquero apresentaram ingestão de matéria seca de 18,3; 16,9; 25,6; 20,7 e 24,2% superior aos animais alimentados com feno de Jiggs, Tifton 68, Coast Cross, Tifton 85 e Russel, respectivamente. Não foi verificada diferença entre as dietas para digestibilidade usando coleta total de fezes e óxido de cromo e peso final dos animais. As dietas a base de feno de Jiggs possibilitaram maior ganho de peso diário e melhor conversão alimentar.

ABSTRACT. This study aimed to evaluate the performance of feedlot lambs fed diets formulated with hay of different genotypes of Cynodon spp. and to compare the dry matter digestibility of diets using different evaluation methods (total fecal collection and chromium oxide). Suffolk crossbred neutered male lambs (n=30), with an average age of 90 days and average body weight of 21.5 kg ± 1.6. Diets were formulated using a standard concentrate and hay of the following genotypes of Cynodon dactylon: Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 and Russell, in a 60:40 forage concentrate ratio, composing the treatments distributed in a randomized block design in a factorial 5 x 2 arrangement of 5 diets and 2 digestibility evaluation methods. Animals receiving Vaquero hay showed dry matter intake of 18.3; 16.9; 25.6; 20.7 and 24.2% higher than those fed hay of Jiggs, Tifton 68, Coast Cross, Tifton 85 and Russell, respectively. There was no difference between diets for digestibility using total fecal collection, chromium oxide and final weight of animals. Jiggs hay based diets allowed greater daily weight gain and better feed conversion.

RESUMO Objetivou-se avaliar o efeito da inclusão de glicerina bruta (GB) em substituição ao milho, na dieta de cordeiros Pantaneiros confinados, sobre as características da carcaça e qualidade da paleta e do pernil. Foram utilizados 24 cordeiros machos, não castrados, em delineamento inteiramente casualizado, com quatro tratamentos (0, 2,5, 5,0 e 7,5% de GB em base da MS). Não houve efeito da inclusão de GB sobre os não componentes de carcaça. Houve efeito quadrático para peso de carcaça quente, com menor valor para 2,5% de GB. A composição regional e tecidual da carcaça não foi alterada pela substituição do milho pela GB. A composição tecidual da paleta e pernil e as características instrumentais da paleta não foram afetadas pelos teores de GB. Houve efeito quadrático para a intensidade de amarelo do pernil, com maior valor para 5,0% de GB. O teor de extrato etéreo da paleta apresentou efeito linear decrescente. Pode-se recomendar a utilização de 7,5% de GB, na matéria seca, em substituição ao milho, sem alteração das características da carcaça e qualidade da carne.

SUMMARY The objective was to assess the effect of inclusion of crude glycerin (CG) replacing corn in the diet of feedlot Pantaneiro lambs on the non-carcass components, regional and tissue composition, and carcass traits. Were used 24 not castrated males, in a completely randomized design with four treatments (0, 2.5, 5.0 and 7.5% of CG on DM basis). There was no effect of GB inclusion on non-carcass components. There was a quadratic effect for hot carcass weight, with lower value to 2.5% of CG. Regional and tissue composition of the carcass was not affected by the substitution of corn by CG. The tissue composition of shoulder and leg and instrumental traits of the shoulder were not affected by CG. There was a quadratic effect for the yellowness of the leg, with high value for 5.0% of GB. The ether extract content of shoulder showed decreased linear effect. The use of 7.5% of CG, in dry matter, can be recommend to replace corn of feedlot diets, without changing carcass traits and meat quality.

ABSTRACT This study assessed the use of conformation and fatness scores of the EUROP sheep carcass grading system to predict weight and percentage of salable meat from Brazilian market lambs. Data were collected from in vivo, carcass, and retail production from 252 uncastrated lambs. Evaluated models included single regressions, two multivariate models, and one determined by the stepwise procedure. Conformation was moderately correlated with weight of salable meat. Fatness scores were correlated with rump perimeter, carcass width, and thoracic depth with coefficients of −0.33, −0.32, and −0.23, respectively. Body weight was the best single predictor for weight of salable meat and cold carcass yield for percentage of salable meat. All multivariate models for weight of salable meat prediction were significant. Stepwise regression with body weight, leg perimeter, thoracic depth, rump perimeter, and fatness scores predicted 98% of weight of salable meat variation. For percentage of salable meat prediction, stepwise regression with cold carcass yield, leg perimeter, and conformation score was significant. The EUROP conformation and fatness scores can be used in Brazil for the prediction of lamb meat production.

ABSTRACT The objective of this study was to evaluate the replacement of soybean meal by crushed crambe on the qualitative characteristics, lipids, and chemical composition of the meat from crossbred Santa Ines ewes. These animals presented an initial body score of 2.5, were finished in confinement for 60 days, fed diets containing crushed crambe replacing 0, 33, 67, and 100% of soybean meal, and slaughtered with a body condition score of 3.5. The statistical design was completely randomized, with slaughter weight used as a covariate in the model. Sensory evaluations were performed in the gluteobiceps muscle by untrained evaluators (n = 100) of different ages. There was no significant effect for color, shear force, or cooking loss of the semimembranosus muscle. The replacement levels of soybean meal influenced only the moisture content, with a linear increase, and the ash content, which decreased linearly. For saturated fatty acids, there was linear effect on capric acid (C10:0), and a linear reduction of myristic (C14:0), pentadecanoic (C15:0), and heptadecanoic (C17:0) fatty acids. There was no influence of the inclusion level of crushed crambe on monounsaturated fatty acids. A linear increase was observed in the polyunsaturated fatty acids linoleic acid (C18:2n-6) and eicosatrienoic acid (C20:3n-3). For the sensory attributes, there were differences only for the variables flavor and tenderness, in which meat was considered more flavorful if it was from animals fed 0% crushed crambe, with an average of 1.6, and considered more tender if it was from animals finished with 15% crushed crambe in the diet, scoring an average of 1.7. Crushed crambe can be considered a promising alternative in the feeding of ewes finished in feedlot, replacing soybean meal in the diet, showing satisfactory results with respect to meat quality.

Para isto, foram utilizadas amostras, seccionadas em bifes de 2,54 cm, do contrafilé e da picanha, provenientes de 35 carcaças de tourinhos da raça Nelore, confinados por 96 dias e abatidos com peso médio de 532,17 ± 30,25 kg e 24 meses de idade. A picanha apresentou os valores mais baixos de proteína e cinzas (18,57 e 0,90%, respectivamente). No entanto, os maiores teores de extrato etéreo também foram encontrados para este corte comparado ao contrafilé (3,37 e 1,90%, respectivamente). Maiores teores de colesterol foram encontrados na picanha em relação ao contrafilé (40,91 e 30,93 mg 100 g-1, respectivamente). O contrafilé in natura apresentou menores teores de ácidos graxos saturados e maiores quantidades de ácidos graxos poli-insaturados. Para as relações dos ácidos graxos ômega-6: ômega-3, os melhores valores foram encontrados na carne in natura. O contrafilé, no presente estudo, mostrou-se mais saudável pela maior quantidade de ácidos graxos poli-insaturados que a picanha. Assar a carne diminui os teores de ácidos graxos poli-insaturados, ômega-3 e ômega-6, além da relação ômega-6: ômega-3.

This study evaluated the chemical and lipid composition of uncooked or cooked loin (Longissimus thoracis) and rump (Biceps femoris) in samples of 2.54 cm thick from 35 carcasses of Nellore young bulls finished in feedlot for 96 days and slaughtered at an average weight of 532.17 ± 30.25 kg and 24 months of age. The rump had the lowest level of protein and ash (18.57 and 0.90%, respectively) and the highest level of ether extract compared to loin (3.37 and 1.90%, respectively). Higher levels of cholesterol were found in rump compared to loin (40.91 e 30.93 mg 100 g-1, respectively). The uncooked loin showed lower content of saturated fatty acids and higher content of polyunsaturated fatty acids. The best values for the omega-6: omega-3 ratio was observed in the uncooked beef. In the present study, the loin was healthier due to the higher amount of polyunsaturated fatty acids compared to rump. Cooking the meat decreases the levels of polyunsaturated fatty acids, omega-3, omega-6 and the omega-6: omega-3 ratio.

Em virtude da grande demanda por proteína de origem animal, tem-se aumentado a produção de frangos de corte e consequentemente a geração de resíduos provenientes do abate de aves, sendo necessário o desenvolvimento de técnicas que permitam o aproveitamento e reciclagem desses materiais. Objetivou-se com a execução deste trabalho avaliar a eficiência da compostagem no tratamento e reciclagem do resíduo sólido de abatedouro avícola. Utilizou-se resíduo sólido de abatedouro avícola comercial composto por fragmentos de vísceras, tecido muscular, adiposo e ósseo, sangue coagulado e penas e, como fonte de carbono, a casca de arroz. Montou-se uma leira com 1,5m3 de volume inicial, na qual foram monitorados os parâmetros: temperatura, teores de sólidos totais (ST), voláteis (SV), N, P, K, carbono orgânico (C), matéria orgânica compostável (MOC), matéria orgânica resistente à compostagem (MORC), demanda química de oxigênio (DQO), massa e volume enleirados, número mais provável (NMP) de coliformes totais e termotolerantes, bem como suas reduções durante o processo. A temperatura máxima atingida no centro da leira foi de 53,3ºC (média semanal), já as reduções de massa de ST e SV e volume durante o processo de pré-compostagem foram de 36,1; 44,3 e 23,3%, respectivamente, e, durante o processo de compostagem, foram de 21,8; 23,8 e 4,4%. A baixa redução do volume das leiras pode estar associada à alta concentração de MORC (40,1%) que pode ser principalmente relacionada à qualidade da fonte de carbono. O processo promoveu satisfatórias reduções totais de ST, SV e volume, sendo, respectivamente, 50,1; 57,5 e 26,7%. No entanto, foram observadas reduções de 43% na quantidade de nitrogênio presente no composto final. Apesar das reduções de nitrogênio, a compostagem demonstrou ser um método eficiente no tratamento dos resíduos sólidos de abatedouro avícola.

The great demand for animal protein was responsible for the increase on the broilers production and hence, the generation of waste from the poultry slaughter was increased as well, which in turn, propelled the development of techniques that allow the reuse and recycling of these wastes. The objective of this study was to evaluate the efficiency of composting on the treatment and recycling of solid waste from poultry slaughterhouse. The solid waste was from a commercial poultry slaughterhouse and was composed of viscera, muscle, fat, bone, blood and feathers that was mixed with a source of carbon, rice husk. Initially, a windrow with a volume of 1.5m3 was built, and then some parameters were monitored: temperature, total solids (TS), volatile (VS), N, P, K, organic carbon (C), composting organic matter (COC), organic matter resistant to composting (MORC), chemical oxygen demand (COD), mass and volume of the windrow, most probable number (MPN) of total and fecal coliforms, as well as their reductions during the process. The maximum temperature reached in the center of the windrow was 53.3°C (weekly average) since reductions of weight of TS and VS and volume during the pre-composting were 36.1, 44.3 and 23.3%, respectively and during the composting process was 21.8, 23.8 and 4.4%. The low volume reduction can be associated with high concentrations of MORC (40.1%) which can be mainly related to the quality of the carbon source. The process produced satisfactory total reductions of TS, VS and volume that were respectively, 50.1, 57.5 and 26.7%. However reductions were observed in 43% of amount of nitrogen in the final compound. Despite reductions in nitrogen content, composting proved to be an effective method in the treatment of solid waste from poultry slaughterhouse.

The objective of this study was to analyze the influence of genetic group (GG) of the calf during gestation, mobilization of body reserves and period of postpartum anestrus in Nellore cows. Thirty-seven primiparous and multiparous cows were used: 24 gave birth to Nellore (NEL), and 13 gave birth to ½ Simmental × ½ Nellore (SIM) calves. According to the date of calving, cows were divided into three blocks, with intervals of 20 days between blocks. The body condition (BC) of the cows was estimated subjectively on a scale from 0 to 5 points, with intermediate grading of 0.5 points. We measured the thickness of subcutaneous fat (SF) between the 12th and 13th ribs and rump by ultrasound. Blood samples from each cow were collected weekly from the third week after birth until weaning, to analyze the level of progesterone; in the samples collected until 16 weeks postpartum, we analyzed the concentration of nonesterified fatty acids (NEFA). The gestation period of mothers of NEL calves was eight days longer, on average. The variables relating to the mobilization of body reserves (NEFA, BC and SF) were not influenced by calf GG, with the only significant effects being the number of days postpartum, with a peak in the concentration of NEFA between the sixth and eighth weeks and linear decrease in BC and NF. Mothers of NEL calves remained in anestrus for 4.6 weeks longer than the mothers of crossbred calves.

The objective was to evaluate the addition of vegetable oils protected or not from rumen degradation in the diet of feedlot-finished young bulls and their effects on performance and carcass characteristics. Thirty-five Nellore males of 402.69±14.90 kg initial weight and 18±2 months of age were utilized. The animals were confined for 96 days, after 28 days of adaptation, and slaughtered at 532.17±30.25 kg. Experimental diets were: control (715 g total digestible nutrients - TDN/kg of dry matter - DM), with addition of soybean oil or fresh linseed oil, and with the addition of the same oils protected from rumen degradation (765 g TDN/kg DM). All diets were formulated with the same amount of protein and with a roughage:concentrate ratio of 40:60, with sugarcane as the only roughage. The addition of oil, regardless of the type and processing, resulted in greater body weight gain (1.17 and 1.41 kg/animal/day), better feed (0.11 and 0.14 kg weight gain/kg DM ingested) and protein efficiency (0.86 and 1.09 kg weight gain/kg crude protein ingested), heavier carcasses (280.3 and 298.0 kg), with better yield (54.5 and 55.5%) and thicker subcutaneous fat (5.1 and 7.5 mm backfat thickness) and with heavier prime cuts, for control diet and the other treatments, respectively. The use of soybean or linseed oil protected or not from rumen degradation only changed the intake of a few nutrients and carcass yield and depth. Thus the addition of energy sources in the diet is beneficial for finishing feedlot bulls. For this addition, either soybean or linseed oils can be used, and the processing of these oils is only useful to facilitate the mixing with the other ingredients of the diet.

The objective of this study was to evaluate the efficiency of anaerobic digestion on the treatment of effluent from poultry slaughterhouse. The experiment was conducted at the Laboratory of Waste Recycling from Animal Production/FCA/UFGD. During four weeks, eight experimental digesters, semi-continuous models, were loaded and set according to the hydraulic retention time (HRT) of 7, 14, 21 and 28 days, and according to the solid fraction treatment, separated with 1 mm sieve or without separation. The average weekly production of biogas and methane as well as the methane concentrations, the potential production per amount of chemical oxygen demand (COD) added and reduced, the concentrations of N, P and K at the beginning and end of process, and the most likely numbers of total and thermotolerant coliforms were evaluated. For data analysis, a completely randomized design was performed in a 4 × 2 factorial arrangement (4 HRT: 7, 14, 21 and 28 days and separation with 1 mm sieve or without separation), with repetition over time. The highest production of biogas and methane was statistically significant for the HRT of 7 and 14 days (5.29 and 2.38 L of biogas and 4.28 and 1.73 L of methane, respectively). There was an interaction between HRT and the separation of the solid with sieve and the highest production was obtained in the treatment without separation. Similar behavior was observed for the potential production with a maximum of 0.41 m³ methane.kg-1 COD added with an HRT of 7 days without separation of the solid fraction. The separation of the solid fraction is not recommended in the pretreatment of liquid effluent from poultry slaughterhouse, once the potential for production and production of methane and biogas were reduced with this treatment.

Para se avaliar o desempenho de novilhas Nelore suplementadas com torta de girassol em substituição ao farelo de soja em 0; 20; 40 e 60% foram utilizados 24 animais, durante a época seca, em delineamento inteiramente casualizado. Os animais foram pesados e monitorados quanto à condição corporal a cada 21 dias. A inclusão de torta de girassol melhorou o ganho de peso diário em 45,8%. A eficiência do uso de concentrados foi de 12,26; 13,42 e 9,87kg/kg para os níveis de substituição de 20, 40 e 60% e o suplemento sem torta de girassol teve eficiência de 7,31kg/kg. A condição corporal dos animais melhorou com o fornecimento dos suplementos, sendo a condição corporal final 3,6; 4,0; 4,0 e 3,7 pontos; para os níveis de substituição de 00, 20, 40 e 60%. Para as características de carcaça não ocorreram diferenças significativas entre os níveis de substituição estudados para peso de abate, peso de carcaça quente, peso de carcaça fria, perdas por resfriamento, rendimento de carcaça, comprimento de carcaça, traseiro, dianteiro, carne aproveitável total, cortes comerciais brasileiros, AOL/100kg, espessura de gordura, fígado. Verificou-se efeito para substituição da torta de girassol somente para acúmulo de gordura perirrenal-pélvica, onde o nível de 60% apresentou o maior valor (3,67kg). A substituição parcial do farelo de soja por torta de girassol melhorou o desempenho de novilhas terminadas a pasto, sem alterar as características de carcaça dos animais.

To evaluate the performance of Nellore heifers supplemented with sunflower cake in partial substitution of soybean meal at 0; 20; 40 and 60% 24 animals were used during the dry season in a randomized design. The animals were weighed and monitored for body condition (BC) every 21 days. The inclusion of sunflower cake improved the average daily gain in 45.8%. The efficiency of the use of concentrated supplements was higher for supplements containing sunflower cake with values of 12.26; 13.42 and 9.87kg/kg for the replacement levels of 20; 40 and 60%. The supplement without sunflower cake had efficiencies of 7.31kg/kg. The BC of animals has improved with the supplementation, of 3.6; 4.0; 4.0 and 3.7 points, for replacement levels of 00; 20; 40 and 60%. For carcass characteristics there was no significant differences between the levels of substitution studied to slaughter weight, hot carcass weight, cold carcass weight, cooling losses, carcass yield, carcass length, back, front, yield estimated grade, Brazilian commercial cuts, AOL/100kg, fat thickness, liver. There was effect for replacement of sunflower cake just for the accumulation of perirenal pelvic fat, where the replacement level of 60% had the highest value (3.67 kilograms). Partial substitution of soybean meal by sunflower cake improved the performance of heifers finished on pastures without changing the characteristics of the carcass.

O objetivo do trabalho foi avaliar a interferência do tempo de acúmulo sobre o desempenho do processo de biodigestão anaeróbia de dejetos de aves de postura. O experimento foi conduzido em delineamento inteiramente casualizado com quatro tratamentos que constaram de 1, 8, 15 e 22 dias de acúmulo dos dejetos, efetuando-se cinco repetições por tratamento, totalizando assim 20 biodigestores. Foram utilizados biodigestores do tipo batelada de bancada com capacidade útil para 3 litros de substrato em fermentação. A eficiência do processo de biodigestão foi avaliada pelas reduções de sólidos totais (ST), sólidos voláteis (SV), número mais provável (NMP) de coliformes totais e termotolerantes, além das produções e dos potenciais de produção de biogás. Foram observadas reduções significativas dos conteúdos de SV presentes nos dejetos de aves à medida que se aumentaram os dias de acúmulo, sendo observados teores de SV (em % dos ST) de 97,1 e 75,6% no primeiro e após 22 dias de acúmulo, respectivamente. A redução de SV contribuiu para reduzir a produção e os potenciais de produção do biogás à medida que se aumentaram os dias de acúmulo, sendo observada redução de 37,2% no potencial de produção de biogás kg de SV-1 entre o menor e maior período de acúmulo, ou seja, 6,81 litros de biogás a menos por dia de acúmulo para cada kg de SV adicionado. Também foram observadas reduções de 100% no NMP de coliformes totais e termotolerantes ao final do processo, independente do tratamento testado. O tempo de estocagem contribui para reduzir os potenciais de produção de biogás dos dejetos de aves de postura.

The objective was to evaluate the interference of the time of accumulation of waste on the performance of the anaerobic digestion process of waste from laying hens. The experiment was conducted in a completely randomized design with four treatments, which observed 1, 8, 15 and 22 days of accumulated waste with five repetitions per treatment, with a total of 20 digesters. It was used batch digesters of bench with useful capacity of 3 liters of substrate fermentation. The efficiency of digestion was evaluated by reductions in total solids (TS), volatile solids (VS), most probable number (MPN) of total and thermotolerant coliforms, beyond the production and potential of biogas production. There were significant reductions in the levels of VS present in the laying hens waste as it increased the days of accumulation, being observed a level of VS (in percent of TS) of 97.1 and 75.6% of VS for 1 and 22 days of accumulation, respectively. The reduction in VS contributed to reduce the production and potential of biogas production as it increased the days of accumulation, and observed a 37.2% of reduction in the potential production of biogas kg VS-1 between the lowest and longer period of accumulation, or 6.81 liters less per day accumulation for each kg of VS added. It was also observed reductions of 100% in the MPN of total and thermotolerant coliforms at the end of the process, independent of the tested treatment. The storage time reduces the potential production of biogas from manure layers.
