| Sumario: | Haymaking is an efficient process of forage conservation through plant dehydration and conditioning is a technique that accelerates the dehydration process. However, its effects on hay, especially after storage, are not yet known. Thus, the aim of this study was to evaluate the chemical composition of ryegrass hay during its dehydration and storage for 56 days. A completely randomized design was adopted with six sampling times. Samples were collected before cutting (-3 days, at the time of baling 0 days, and at 14, 28 and 56 days of storage). In the collected samples, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, cellulose and hemicellulose were determined. The ADF, lignin and CP contents showed a linear increase in response to storage time, while hemicellulose was linearly reduced. TheNDF and cellulose contents were not affected by the dehydration and storage times of the ryegrass hay. Storage of ryegrass hay for up to 56 days reduces the content of hemicellulose, DGMS and TDN and increases the contents of ADF, lignin and CP, without affecting NDF, cellulose and VRF. Dehydration does not harm the chemical composition of ryegrass forage. The nutritional value of ryegrass hay is maintained for up to 28 days of storage, this being the recommended limit period for storage. |
