Resumo
This work was carried out to determine the effect of
fibrolytic enzymes levels on the bromatologic composition
and in situ degradability of dry matter (DM ) and neutral
detergent fibre (NDF) of tropical grasses silage. The
experiment consisted of four enzymatic levels (0, 5, 10 and
20 mg of enzymes for kg natural matter), two periods of
storage (45 and 120 days) and three repetitions. After the
storage, the silos were opened and the content analyzed
for dry matter (DM), crude protein (CP), neutral detergent
fiber (NDF), ammonia N and pH. In the study of in situ
degradability of DM and NDF. It was used the nylon bag
technique with three canullated bovine and the times
incubations were 6, 24 and 96 hours and sample of 45 days
ensiling. The experimental period was of 36 days. The
solution didn’t modify the content of DM, CP, ammonia N
and pH of grasses silage. In case of NDF, Brachiaria silage
treated with 20 mg level showed lower fiber content (67,99%)
versus untreated control (70,28%), suggesting an improvement
in the nutritive quality. There was no difference among
period of storage neither interaction period of storage and
enzymatic level. In situ rumen degradation, there was no
difference among the treatments to the degradation of DM
and NDF of grasses silage.,there was no difference among
the treatments to the degradation of NDF of grasses silage.
