Resumen

Objetive. This experiment was conducted to evaluate the best sunflowermeal concentration in Massai grass silage. Materials and methods. The treatments were composed of 0, 8, 16, and 24% sunflowermeal (natural matter basis) during ensiling of Massai grass, with four repetitions. Results. The regression equation showed that the inclusion of sunflowermeal between 2.14% and 13.91% obtained a silage dry matter between 25 and 35%, which are the values recommended for the production of high quality silage. The addition of sunflowermeal showed a linear increase in crude protein, reaching 18% DM with the highest concentration of sunflowermeal. The highest feed value index was obtained with the addition of 24% sunflowermeal in the silage. The estimated total digestible nutrient of silage increased linearly with sunflowermeal concentration. The silage pH values had a quadratic effect, reaching the lowest value (4.1) with 15% sunflowermeal addition. Conclusions. Based on the chemical composition and forage quality, a concentration of 14% sunflower meal should be used for high-qualiy silage with good nutritional value.
