Table 1. Treatments evaluated for making maize + forage soybean silage<br />
(Pacific Coast, Costa Rica).<br />
Treatment Maize:soybean ratio Condition of forage<br />
T1 1:1 No removal of ears<br />
T2 1:1 Removal of 50% tender maize<br />
T3 1:1 Removal of 50% baby corn<br />
T4 2:1 No removal of ears<br />
T5 2:1 Removal of 50% tender maize<br />
T6 2:1 Removal of 50% baby corn<br />
T7 3:1 No removal of ears<br />
T8 3:1 Removal of 50% tender maize<br />
T9 3:1 Removal of 50% baby corn<br />
The microsilos were left open after 70 days fermentation and pH and<br />
organoleptic characteristics (odor and color) were assessed according <strong>to</strong> the<br />
following scale:<br />
Organoleptic<br />
Scores and properties of silage<br />
characteristics 1 = Poor 2 = Intermediate 3 = Good<br />
Odor Butyric (rancid)<br />
Degraded amino acids<br />
or N sub-products<br />
(spoiled)<br />
Color Dark brown<br />
Black<br />
Moldy<br />
41<br />
Acetic<br />
Alcoholic<br />
Light brown<br />
Yellowish<br />
Lactic<br />
Slightly acetic or<br />
alcoholic <strong>with</strong><br />
lactic essence<br />
Original green<br />
Light green<br />
Part of each sample was oven-dried at 60 °C and a subsample was<br />
frozen <strong>to</strong> later analyze ammonium nitrogen (Nam). Labora<strong>to</strong>ry tests were<br />
conducted <strong>to</strong> determine: (1) dry matter (DM), organic matter (OM) and crude<br />
protein (CP) contents; (2) Nam; and (c) rate of rumen degradability of dry<br />
matter (D). Treatments were organized in a completely randomized design<br />
<strong>with</strong> three replicates.
