Autores: Veloso,Alessandro V.; Campos,Alessandro T.; Paula,Vanderson R. de; Dourado,David C.; Yanagi Júnior,Tadayuki; Silva,Enilson B.
The aim of this work was to evaluate the energy flows of a commercial production system of swine deep bed in its finishing phase, located in Juiz de Fora, in the State of Minas Gerais, Brazil. Thus, an energy efficiency study was carried out by monitoring a lot of animals, during a 94-day period. The energy rate of each compound involved in the production process was quantified and the matrixes of energy consumption were determined in the form of animal feeding, electrical energy, piglets, material used as deep bed, human labor, equipment, swine buildings, production of alive swine for slaughter, organic fertilizer production (swine deep bed or swine deep litter). From the direct input energy, 80.57% correspond to animal feeding, 11.90% to pigs for...

Nitrogen fertilization by deep bedding swine production and its effects on dry matter production and accumulation of nutrients by maize
Provedor de dados: 70
Autores: Campos,Alessandro T.; Veloso,Alessandro V.; Silva,Enilson B.; Yanagi Júnior,Tadayuki; Mattioli,Matheus C.
The goal of this study was to evaluate the nitrogen fertilization as deep litter for pigs in order to produce biomass and accumulate nutrients by the corn. A deep litter made of rice husk as organic compound, from a commercial pig farm during finishing phase, was used. After three consecutive batches of pigs, the deep litter was subjected to a maturation period of 50 days, and samples of this material were taken for analysis of agronomic value. The experimental design was completely randomized with five replicates. The treatments consisted of doses of 0, 75, 150 and 300mg dm-3 of N of deep litter, as well as an additional treatment with ammonium sulfate, with a dosage of 150mg dm-3 of N. After 45 days, corn plants were harvested in order to evaluate the...

Análise energética em sistema de produção de suínos com aproveitamento dos desejos como biofertilizante em pastagem
Provedor de dados: 70
Autores: Souza,Cássio V.; Campos,Alessandro T.; Bueno,Osmar C.; Silva,Enilson B.
O objetivo deste trabalho foi estimar a quantidade de energia para a produção de suínos, em ciclo completo, e o balanço energético do sistema com reaproveitamento dos resíduos gerados como biofertilizante, em área de pastagem, utilizando dados médios de cinco ciclos, em granja comercial no município de Diamantina - MG. Quantificou-se o coeficiente energético de cada componente envolvido no processo produtivo de suínos terminados, tratamento dos resíduos e produção de pastagem de Brachiaria decumbens, nas formas de ração, trabalho humano, energia elétrica, máquinas e equipamentos, combustíveis e lubrificantes, instalações, produção de suínos vivos e produção de Brachiaria decumbens. A quantidade média de energia para produzir 1 kg de suíno vivo foi de 53,35...
