Abstract
This study aims to study the concentration of the addition of formic acid to the silage which is most effective in increasing the nutritive value of the Pennisetum purpureum silage. Formic acid used in liquid form which is divided into treatment 0; 0.15; 0,3 and 0,45% by weight of forage then cut off forages then divided into the treatment T0 = giving formic acid 0% by weight of forage, T1 = giving formic acid 0,15% by weight of forage, T2 = giving formic acid 0,3% forage weight, T3 = giving formic acid 0,45% forage weight. Each treatment was repeated 4 times. The experimental design used was a randomized block design in the same direction. The analysis included water content, crude protein content and crude fiber silage content. This research can be concluded that the addition of 0.15% formic acid in the making of Pennisetum purpureum forage silage provides the best nutritive content and performance of 52.15% water content, PK 12.28%, crude fiber 9.51% and attractive performance that is fresh, warm and flavorful. acid, the addition of formic acid 0.3% in making forage silage Pennisetum purpureum gave nutritive content not significantly different from the control and the addition of formic acid 0.45% in making forage silage Pennisetum purpureum gave significantly different nutritive content (P <0.05) with control but low performance and perishable
