Resumo

We aimed to evaluate the effect of the inclusion of corn and citrus pulp as additives in soybean silage made in plastic (PVC) tubes. The experimental design was completely randomized, with a 2x4 factorial arrangement consisting of two additive groups (corn and citrus pulp) and four inclusion levels (no inclusion, 7, 14 and 21%). The experiment was conducted at the Forage Sector of the Lageado Experimental Farm, Faculty of Veterinary Medicine and Animal Science, UNESP, Botucatu, SP, and chemical composition analysis was carried out at the Laboratory of Bromatology. The soybean variety used was BMX Potência RR. Mechanical harvest occurred at the R7 phenological stage, at a height of 15 cm, using a harvester equipped with a two-row platform. The material was chopped into medium particles of 3 to 6 mm. After 45 days, the silages were analyzed for dry matter, crude protein (CP), total digestible nutrients, pH, ethereal extract, neutral detergent fiber, acid detergent fiber, lignin, total dry matter loss, and total carbohydrates (CHOS). The inclusion of corn (21%) and citrus pulp (14 and 21%) reduced CP values (P<0.05). Control silage contained less CHOS (P<0.05). The inclusion of corn meal is better than citrus pulp to improve the values of soybean silage.
