Merr.). The treatments were: corn forage alone or control (FM); Corn with inclusion of 10% soybean forage (FS10); Corn with 20% soybean forage (FS20); T4, Corn with 30% soybean forage (FS30); T5, Corn with 5% chicken manure (G5); T6, Corn with 10% chicken manure (G10) and T7, Corn with 15% chicken manure (G15). It was evidenced that the addition of poultry manure significantly increased the content of dry matter (DM), while the soybean forage (FS) presented similarity with the control. The total protein content (TP), due to the effect of the addition of FS, was higher than the other treatments studied. The nitrogen sources used did not affect the total fiber content (TF). The ash concentration value (C) was strongly affected by the addition of chicken manure. The content of ammoniacal nitrogen (N-NH3) increased with the inclusion of chicken manure in the silage process. The pH value, the concentration of lactic and butyric acid was significantly higher with the addition of chicken manure. In conclusion, it can be indicated that the addition of both chicken manure and soybean forage improve the nutritional content of corn silage, however, the inclusion of soybean forage is much more favorable in terms of fermentative variables. |
