Abstract

Abstract
The objective of this study was to evaluate the influence of the time of cutting on the nutritive value of Piatã silage grass in monocrop and intercropping with sorghum for cutting and grazing. We used a randomized block design with four replications. Treatments were arranged in a split plot design, with systems as plots (Piata grass, sorghum for cutting and grazing, and intercropping), cutting ages as sublots (70, 90, and 110 days after sowing). The minisilos were opened at 46 days to evaluate silage crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN), ammonia nitrogen, lignin, and pH. We observed significant interaction between system and age on the variables CP, ADF, NDF, lignin and pH. With the advancement of age, there was a linear reduction in crude protein content of 0.12, 0.08, and 0.16 percentage units for each day after sowing in sorghum silage, sorghum grass and grass + Piata, respectively. There was a linear increase in the pH value of sorghum silage + grass due to the advancement of age of 0.03 units for each day after sowing. In sorghum silage and monocrop grass, the pH did not vary with the cutting age, with values of 4.63 and 5.20, respectively. Sorghum systems showed potential for the production of good quality silage at 70 days of age.
