Assessment of the agronomic potential of two types of deep-bedding swine
The aim of this study was to assess two deep-bedding swine with different substrates, shavings woods and sugarcane bagasse through analyses of 6 lots with 40 animals to determine their agronomic potential as a fertilizer. Each pen housed the animals in the finishing phase for 90 days. Samples were c...

| Sumario: | The aim of this study was to assess two deep-bedding swine with different substrates, shavings woods and sugarcane bagasse through analyses of 6 lots with 40 animals to determine their agronomic potential as a fertilizer. Each pen housed the animals in the finishing phase for 90 days. Samples were collected at the time of removal of both beds, after 1 year of use. The results showed that the bed sugarcane bagasse presented a higher concentration of minerals due to their higher decomposition, while the bed with shaving woods had a higher concentration of carbon, causing an increase in the ratio of carbon/nitrogen, promoted by a lower mineralization of the organic matter due to the presence of large-scale lignificant material in the timber. The average concentration of nutrients found in the beds, makes it as a possible source of organic fertilizer for use on crops. |
