VIEIRA, Valmir da Cunha et al. Characterization of corn silage produced in farms of Southwest Paraná State, Brazil. Rev. Ceres (Impr.) [online]. 2011, vol.58, n.4, pp.462-469. ISSN 0034-737X.

The objective of this work was to characterize the production and utilization of corn silage in milk farms in Paraná State, Brazil. Data was collected from March to May, 2009, in seven municipalities, comprising 108 farms visited. A quali-quantitative questionnaire consisting of 28 predefined questions was applied to farmers. Milk production can be increased by adopting management techniques such as the correct hybrid choice, planning and right sowing scheduling. The southwestern region of the Paraná is characterized by small farms, with 15.65 cows in lactation and 17.2 liters of milk/day, on average, and the silage is stored mainly in trench silos. The cultivated areas for silage produce 40 to 50 ton ha-1 on average of fresh matter.The main corn hybrids used for silage belong to the semi-hard and early group, with certified and treated seeds.
