Resumo
This study aimed to evaluate the chemical composition and fermentation characteristics of silage
millet farming ADR500 under the inclusion of different levels of corn disintegrated with straw and
cob (CEC): 0%, 5%, 10% and 15%, after 78 days of vegetative growth and observe his capacity as
moisture scavenger in silage. The experimental design was completely randomized with 4
treatments and 4 replications, totaling 16 experimental units. Data were submitted to analysis of
variance, means were compared by 5% Tukey test and regression analysis for the inclusion levels.
dry matter content (DM) determined in silage differ (P <0.05) as a function of the MDPS inclusion
levels, ranging from 26.53% to 38.69% control treatment and for treatment with higher level
inclusion. For values of organic matter found a significant difference only from the IV treatment
with 15% inclusion of CEC (P <0.05) compared to other treatments. Regarding crude protein (CP)
observed a linear increase (P <0.05) due to the increase of CEC levels, ranging between 9.46% and
14.92%. NDF and the FDA determined in silages ranged from 58.50% to 66.25% and 31.25% for
FDA to 38.50 for the FDA so there significant differences between treatments. For certain ether
extract in silages millet forage with inclusion of MDPS ranged from 3.13 to 3.95%. The content of
mineral matter (MM) showed a significant difference (P <0.05) according to the MDPS inclusion
levels, ranging from 5.26 to 7.55%. The inclusion of MDPS reduced (P <0.05) losses gases and
effluents in all the treatments, ranging from 6.10 to 3.48 for gas losses and 9.05 to 17.28 for losses
effluent and contributed significantly in the dry matter recovery process (MS). The buffer power
values (PT), pH and ammonia-N were influenced (P <0.05) by the inclusion of different levels of
ground ear corn silage. The levels of acetic, propionic, butyric and lactic, so influenced by the
addition of ground ear corn silage. The soluble carbohydrate values have an increasing depending
on the MDPS inclusion levels, proving to be efficient in their use to improve the fermentation
profile of silages.
