Abstract

The objective of this study was to evaluate the storage and nutritional quality of ensiled branch of cassava cultivars Pão and IAC 7650 and the influence of pre-drying. The following treatments were evaluated: SPSD, ensiling of branch of cassava cv. Pão; SPD, ensiling of pre-dried branch of cassava cv. Pão; SISD, ensiling of branch of cassava cv. IAC 7650; SID, ensiling of predried branch of cassava cv. IAC 7650. A completely randomized design with or without pre-drying and four replicates was used. The pH and buffering capacity were determined for the evaluation of silage storage, and dry matter, organic matter, mineral matter, crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) content for the assessment of nutritional quality. Both cultivars exhibited characteristics for the use of branch as silage after pre-drying. The highest content of partial and total dry matter was observed for the IAC 7650 cultivar after the period of drying and no significant difference (P>0.05) was found in fibrous content. Regarding silage quality, the buffering capacity was influenced (P<0.05) by the dehydration process, while pH ranged from 3.93 to 4.43. Highest values of total dry matter content were found for silage after drying process.. Crude protein content was higher in silage of the Pão cultivar and pre-drying exerted no significant influence (P>0.05). A lower NDF content was observed in SPSD, while there was no significant difference in ADF content (P>0.05). Dehydration of the branch of cassava is efficient in controlling the buffering capacity of the two cultivars and the pH obtained is adequate. The nutritional value continued satisfactory even after dehydration, with a higher protein content in the Pão cultivar.
