Resumo: | The objectives of this study were to estimate the curve of dehydration, bromatological composition and occurrence of fungi in Tifton 85 grass, submitted to four methods of dehydration. The curves of dehydration were studied in a completely randomized design with a 4 × 11 factorial scheme with four drying systems (1 conditioning + 1 turn-over; 2 conditionings + 1 turn-over; no conditioning + 1 turn-over and no conditioning + 2 turn-overs) and 11 sampling times (0, 3, 15, 18, 21, 24, 39, 42, 45 and 47 hours after the cutting), with six replicates. For the bromatological composition and fungi occurrence, the experimental design was completely randomized in a 4 × 3 factorial scheme with the four drying methods of Tifton 85 grass and three periods of evaluation (before the cutting, at the time of the baling and 30 days after storage) with six replicates. It was found that after the first hour after cutting and at the end of the period of dehydration, Tifton 85 plants that were treated with conditioners showed higher levels of dry matter. Stored hay that was treated with conditioners presented higher levels of acid detergent insoluble protein. Until baling, the drying methods did not alter the crude protein content of hay; however, after storage, the hay submitted only to turn-over showed crude protein content higher (13.90%) than those submitted to conditioners (9.94%). There was an increase in the occurrence of fungi after storage, but the application of conditioners and one turn-over resulted in lower CUF/g, compared with other treatments, enhancing the effect of conditioners on accelerating the dehydration rate and obtaining better hay storage conditions |
