ABSTRACT: This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of total solids (TS), volatile solids (VS), and neutral detergent fiber (NDF) were performed during the loading and unloading of digesters, while biogas yield was measured twice a week. The maximum reduction in VS (51.4%) was reached with the inclusion of up to 54.6g waste cooking oil.kg manure-1. Maximum NDF degradation occurred with inclusions of up to 69.4g waste cooking oil.kg manure-1. Inclusions of up to 64g of waste cooking oil.kg manure-1 provided specific biogas yield of 291.4 and 251.0L biogas.kg VS-1 added to substrates with swine and cattle manure, respectively. Adding oil at doses between 45.1 and 69.4g waste cooking oil kg manure-1 to substrates composed of cattle or swine manure maximizes reductions of solids and fibrous constituents and enhances specific biogas yield. Furthermore, swine manure supports higher doses of waste cooking oil.

O objetivo do trabalho foi verificar a eficiência da co-digestão anaeróbia dos dejetos suínos com crescentes níveis de adição de óleo de descarte e lipase. Foram testadas quatro doses de óleos (8, 12, 16 e 20g kg-1 de substrato) e 3 doses de lipase (1, 2 e 3g kg-1 de substrato). Os parâmetros avaliados foram: redução de sólidos totais (ST), sólidos voláteis (SV) e número mais provável (NMP) de coliformes totais (CT) e termotolerantes (CTT), além do pH, demanda química de oxigênio (DQO), produção e potenciais de produção de biogás. Os resultados demonstraram que houve influência das adições de óleo e lipase sobre as reduções de ST SV e pH do efluente, seguindo um modelo de predição linear e decrescente. As reduções do NMP de CT e CTT foram mais elevadas nos tratamentos com maior adição de óleo e lipase. A produção de biogás apresentou uma correlação negativa com as adições de lipase, sendo que estas proporcionaram efeito linear decrescente sobre os potenciais de produção de biogás/kg de dejeto, ST e SV adicionado. As adições de óleo e lipase não proporcionam efeitos favoráveis sobre as produções de biogás.

O objetivo do trabalho foi avaliar diferentes doses de efluente de abatedouro avícola para proporcionar melhorias nas características produtivas, morfogênicas e estruturais do capim-piatã. O experimento foi conduzido em casa de vegetação, adotando-se delineamento inteiramente casualizado, em que foram testadas cinco doses de efluentes: 324, 648, 972, 1.296 e 1620m³ ha-1 ou equivalente a 50, 100, 150, 200 e 250kg ha-1 de N. As variáveis mensuradas foram: produção de matéria seca (MS), taxa de aparecimento de folha (TApF), taxa de alongamento de folha (TAlF), filocrono, taxa de alongamento de pseudocolmo (TAlC), comprimento final de folha (CFF) e números de folhas verdes (NFV). A produção de MS seguiu um modelo linear de predição em função das doses efluente avícola, em que o tratamento com 250kg ha-1 de N foi 55% maior, quando comparado com o tratamento de 50kg ha-1 de N. Todas as características morfogênicas e estruturais avaliadas com exceção do filocrono apresentaram comportamento linear positivo. Dessa forma, o efluente de abatedouro avícola pode ser utilizado como uma alternativa para adubação do capim-piatã, pois este respondeu de maneira crescente até a dose máxima testada.The organic fertilizer is considered a viable alternative for the production of forage grasses. However there is little information about the rates and composition of the organic fertilizers. According to this assumption the objective of this study was to figure out the best dose of effluent from poultry processing plants in order to improve the structural, morphogenetic and productive characteristics of Piata palidadegrass. The experiment was carried out at a greenhouse and performed in a completely randomized design in which five doses of effluent, 324, 648, 972, 1296 and 1620m³ ha-1 were tested and equivalent to 50, 100, 150, 200 and 250kg ha-1 de N respectively. The measured variables were: dry matter (DM), leaf appearance rate, leaf elongation rate, phyllochron, pseudo stem elongation rate, final leaf length and numbers of green leaves. The production of DM presented a linear prediction model according to the N rates, while the treatment with 250kg ha-1 de N was 55% higher when compared to the treatment with 50kg ha-1 de N. All morphogenetic and structural characteristics that were evaluated presented a positive linear fashion, except the phyllochron. Thus, the effluent from poultry processing plant may be used as an alternative to fertilization of the 'Piata' palisadegrass because this responded by increasing the maximum dose tested.

O objetivo do trabalho foi verificar a influência das diferentes doses de composto orgânico produzido com dois tipos de cama de frango sobre as características produtivas, morfogênicas e estruturais de Brachiaria brizantha, cv 'Piatã'. O experimento foi conduzido em casa de vegetação em delineamento inteiramente casualizado, em esquema fatorial com parcela subdividida no tempo. As parcelas foram compostas por seis tratamentos: dois tipos compostos (cama de frango a base de cana de açúcar ou napier) em três doses (100, 200 e 300kg ha-1 equivalente N) e as subparcelas pelos quatro períodos de cortes. Os compostos foram aplicados em dose única, após o corte de uniformização, nas quantidades de: 11,36 e 11,83, 22,73 e 23,67, 34,09 e 35,50g vaso-1 para os compostos de cama de frangos a base de cana de açúcar e capim napier, respectivamente, que equivalem às doses de 100, 200 e 300kg ha-1 de N. As variáveis mensuradas foram: produção de matéria seca (PMS), taxa de aparecimento de folha (TApF), taxa de alongamento de folha (TAlF), filocrono, taxa de alongamento de pseudocolmo (TAlC), comprimento final de folha (CFF) e números de folhas verdes (NFV). Não foi observada diferença significativa entre os tipos de composto e na interação composto x dose. Dessa forma, ambos poderiam ser utilizados sem que ocorresse prejuízo no aproveitamento dos nutrientes pelas plantas avaliadas no experimento. Houve diferença significativa entre a PMS, TApF, filocrono, TAlF e TAlC, NFV e TFF em função das doses crescentes de nitrogênio, segundo um modelo linear de predição. Também foi observado efeito dos períodos de corte, em que os cortes realizados no verão apresentaram melhor desempenho sobre as características morfogênicas e estruturais. The organic fertilizer can be a viable alternative in the production of forage grasses, however there is little information regarding doses and composition of the major organic fertilizers. The aim of this paper was to verify the influence of the different doses of organic compost produced from two types of poultry litter on the structural, morphogenetic and productive characteristics of Brachiaria brizantha cv 'Piatã'. The experiment was conducted in a greenhouse in a completely randomized design in a factorial scheme l with parcel subdivided in time. The parcels were composed by six treatments: two types of compost (poultry litter based in sugar cane and napier grass) in three doses (100, 200 and 300kg ha-1 equivalent N.) and the subparcels by the four different periods of cut. The composts were applied in a unique dose, after the uniformization cut, at the quantities: 11,36 and 11,83, 22,73 and 23,67, 34,09 and 35,50 g pot-1 for the poultry litter based in sugar cane and napier grass, respectively which are equivalent to the rates of 0, 100, 200 and 300kg ha-1 of N. The variables measured were: dry matter production (DMP), leaf appearance rate (LApR), phyllochron, leaf elongation dose (LER) and shoots elongation rate (SER), number of green leaves (NGL), final size of the leaf (FSL). No significant difference between the types of composts and in the interaction compost x doses was observed, thus, both could be used without the risk of loss in the use of the nutrients by the plants evaluated in the experiment. There was a significant difference between the DMP, LApR, phyllochron, LER, SER, NGL and FSL because of the increasing rates of nitrogen, followed by a linear model of prediction. The effect of the periods of slaughter was also observed, where the slaughters carried out in the summer presented a better performance over the morphogenetic and structural features evaluated.

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 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.

The organic fertilizer can be a viable alternative in the production of forage grasses, however there is little information regarding doses and composition of the major organic fertilizers. The aim of this paper was to verify the influence of the different doses of organic compost producedfrom two types ofpoultry litter on the structural, morphogenetic and productive characteristics of Brachiaria brizantha cv 'Piatã'. The experiment was conducted in a greenhouse in a completely randomized design in a factorial scheme I with parcel subdivided in time. The parcels were composed by six treatments: two types of compost (poultry litter based in sugar cane and napier grass) in three doses (100, 200 and 300kg ha-1 equivalent N.) and the subparcels by the four different periods of cut. The composts were applied in a unique dose, after the uniformization cut, at the quantities: 11,36 and 11,83, 22,73 and 23,67, 34,09 and 35,50 g pot-1 for the poultry litter based in sugar cane and napier grass, respectively which are equivalent to the rates of 0, 100, 200 and 300kg ha-1 of N. The variables measured were: dry matter production (DMP), leaf appearance rate (LApR), phyllochron, leaf elongation dose (LER) and shoots elongation rate (SER), number of green leaves (NGL), final size of the leaf (FSL). No significant difference between the types of composts and in the interaction compost x doses was observed, thus, both could be used without the risk of loss in the use of the nutrients by the plants evaluated in the experiment. There was a significant difference between the DMP, LApR, phyllochron, LER, SER, NGL and FSL because of the increasing rates of nitrogen, followed by a linear model ofprediction. The effect of the periods of slaughter was also observed, where the slaughters carried out in the summer presented a better performance over the morphogenetic and structural features evaluated.

ORGANIC fertilizers , *FORAGE plants , *GREENHOUSES , *POULTRY processing plants , *PLANT fertilization - Abstract
The organic fertilizer is considered a viable alternative for the production of forage grasses. However there is little information about the rates and composition of the organic fertilizers. According to this assumption the objective of this study was to figure out the best dose of effluent from poultry processing plants in order to improve the structural, morphogenetic and productive characteristics of Piata palidadegrass. The experiment was carried out at a greenhouse and performed in a completely randomized design in which five doses of effluent, 324, 648, 972, 1296 and 1620m3 ha-1 were tested and equivalent to 50, 100, 150, 200 and 250kg ha-1 de N respectively. The measured variables were: dry matter (DM), leaf appearance rate, leaf elongation rate, phyllochron, pseudo stem elongation rate, final leaf length and numbers of green leaves. The production of DM presented a linear prediction model according to the N rates, while the treatment with 250kg ha-1 de N was 55% higher when compared to the treatment with 50kg ha-1 de N. All morphogenetic and structural characteristics that were evaluated presented a positive linear fashion, except the phyllochron. Thus, the effluent from poultry processing plant may be used as an alternative to fertilization of the 'Piata' palisadegrass because this responded by increasing the maximum dose tested.

ANIMAL waste , *HENS , *BIOACCUMULATION , *BIOGAS production , *COLIFORMS - Abstract
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 [ABSTRACT FROM AUTHOR]

The objective was to evaluate the effect of nitrogen fertilization levels on productivity, and nutritional value of BRS Kurumi managed at different residue heights during rainy and dry periods of the year. The pasture was managed in three residue heights (20, 35, and 50 cm) and three nitrogen fertilization levels (0, 100, and 200 kg N/ha/year) during the rainy and dry seasons. When the height of the grass of each plot reached 80 cm, the Kurumi was cut manually at the pre-established residue heights. Around 89% of the dry matter (DM) production was observed during the rainy season. The residue height of 35 cm together with doses of 100 or 200 kg N/ha/year, and the residue height of 20 cm, with a dose of 100 kg N/ha/year were the treatments that had the highest DM production during the rainy period. No differences in DM production were observed between tested treatments during the dry period. The Kurumi cultivated during the dry period had the highest content of neutral detergent fiber and lowest digestibility. The Kurumi managed with residue heights of 20 and 35 cm and fertilized with 100 kg N/ha had the highest values of efficiency of utilization applied nitrogen. The use of 20 or 35 cm of residue height and 100 kg of N/ha/year is recommended to obtain greater biomass production and nutrients, nutritional quality, and nitrogen use efficiency.

ABSTRACT: This research evaluated the biomass productivity and nutritional value of the haylage and hay from intercropping between Tamani grass and different legume species. For the productive characteristics of the different intercrops, we adopted a randomized block design, for evaluation of the combination of intercropping and conservation technic we used 5 x 2 factorial scheme (five intercrops and two types of conservation techniques). The treatments were Tamani grass as monoculture, and the intercrops of Tamani grass with crotalaria, soybean, cowpea, or pigeon pea. The conservation techniques were haylage (520 g/kg of DM) and hay (870 g/kg of DM). Plants were sown in alternate rows, with 45 cm of spacing between the rows. The parameters evaluated were grass and legume biomass production, canopy height, and haylage and hay chemical composition, and in vitro dry matter digestibility (ivDMD). There were no differences in the total biomass production between the intercrops and TA grass monoculture. The treatments intercropped with cowpea and soybean had the highest legume participation in the mixture, promoting an increase in crude protein and ivDMD content of haylage and hay. Haylage and hay had the same chemical composition, although haylage had higher ivDMD than hay. We concluded that intercropping Tamani grass with soybeans or cowpea maintained total biomass productivity and improved the nutritional value of haylage and hay.
