Swine manure post-treatment technologies for pathogenic organism inactivation
Provedor de dados: 70
Autores: Bilotta,Patrícia; Kunz,Airton.
Swine manure agricultural use is a common practice in Brazil. Their physic-chemical characteristics favor its use as biofertilizer, but the presence of pathogens may become a risk to human health. This research presents a qualitative study of the main alternatives of pig manure disinfection, analyzing efficiency, advantages and limitations of each procedure. The disinfection studies reported in literature are based on the following treatments: alkaline, thermal, biological, chemical, and physical. The greater efficiencies are in thermal treatment (&gt; 4 log: 60 °C), chemical treatment (3 to 4 log: 30mg Cl- L-1; 3 to 4 log: 40 mg O3 L-1) and physical treatment (3 a 4 log: 220 mJ UV radiation cm-2). The biological treatment (anaerobiosis) also promotes the...

Provedor de dados: 14
Autores: NUNES, M. U. C.; MOURA, G. de M.
A incorporação de leguminosas no estadio de floração visa principalmente o aumento de matéria orgânica e nitrogênio. Essa prática beneficia as propriedades físicas, químicas e biológicas do solo, propiciando na maioria dos casos aumento de produtividade da cultura, a seguir implantada. A adubação verde no período da entressafra proporciona maior controle da erosão e da infestação de nematóides, melhora a retenção de água e adubos químicos no solo, controla as plantas daninhas e plantas hospedeiras de pragas e doenças, além dos benefícios acima citados. Em consequência reduz a utilização de insumos como herbicidas, inseticidas, fungicidas, nematicidas e fertilizantes. Os efeitos benéficos da adubação verde sobre a produtividade de diversas culturas como o...

Provedor de dados: 14
Autores: MENEZES, L. M. F.; ÂNGELO, F. F.; ALCINDO, J. F.; SÁ, D. M. A. T.; SOUZA, V. de.
Resumo: A mastite é uma das doenças mais comuns em propriedades leiteiras causando prejuízos, principalmente pela redução na produção de leite decorrente da invasão do agente infeccioso no epitélio secretor da glândula mamária. O uso de antibióticos adequados é uma importante ferramenta para o tratamento da enfermidade, sendo que deverão ser empregados de forma criteriosa, uma vez que a resistência bacteriana aos fármacos é a principal causa de falha de terapias. O presente estudo teve como objetivo avaliar o perfil de sensibilidade antimicrobiana in vitro de cepas de Staphylococcus aureus isolados de amostras de leite de cabras, obtidas a partir de casos de mastite subclínica de um rebanho do Estado de Minas Gerais e São Paulo. Verificou-se que a...

Durabilidade de estacas de eucalipto (Eucalyptus sp.) tratadas com CCA após 60 meses de ensaio no campo experimental da Embrapa Acre, Rio Branco, Acre.
Provedor de dados: 14
Autores: ARAUJO, H. J. B. de; MAGALHAES, W. L. E.; OLIVEIRA, L. C. de; SA, C. P. de; CORREIA, M. F.
Atualmente, no Acre, o preço das estacas tratadas de eucalipto para cercados é bastante competitivo como das estacas de espécies nativas tradicionalmente utilizadas em contato com o solo, mesmo considerando os custos do tratamento preservativo e do transporte do centro-sul do país, pois não há no estado plantios dessa espécie e tampouco unidades industriais (usinas) de preservação. Outro aspecto vantajoso do uso de espécies plantadas e tratadas em substituição às tradicionais é de ordem ambiental, uma vez que a pressão exploratória sobre as espécies nativas será reduzida, o que é muito positivo do ponto de vista de conservação e recomposição dos estoques naturais. O presente estudo objetiva avaliar o grau de degradação de organismos xilófagos, fungos e...

Provedor de dados: 96
Autores: Santos,Wallacy Barbacena Rosa dos; Santos,Geraldo Tadeu dos; Neves,Carolina Antunes; De Marchi,Francilaine Eloise; Silva-Kazama,Daniele Cristina da; Ítavo,Luís Carlos Vinhas; Damasceno,Julio Cesar; Petit,Hélène Veronique.
Four multiparous Holstein cows averaging 548 kg of body weight and 74 d in lactation were used in a Latin square design with four 21-d experimental periods to determine effects of feeding extruded versus non-extruded canola seed, with or without 50 g/kg lignosulfonate on rumen fermentation, nutrient flow to the omasum, and degradability of dry matter (DM) and N of each diet. The DM effective degradability increased with extrusion and lignosulfonate treatment had no effect. The effective degradability of N was similar between diets. Lignosulfonate treatment of extruded versus non-extruded canola seeds decreased ruminal and total tract apparent digestibility of organic matter. The lowest apparent ruminal and highest intestinal digestibilities of protein,...
