Abstract
The present study used Napier grass and corn of two maturities to test the silage
making by (1)control without additive, (2)added with Lactobacillus planetarium,
(3)added with Lactobacillus planetarium in combination with cellulose and xylanase,
(4)same as treatment 3 with addition of α-L-arabinofuranosidase and feruloyl esterase.
Compared to the control, treatment 2 resulted in significantly lower silage pH and
higher silage score along with higher in vitro dry matter digestibility (IVDMD).
Usage of fibrolytic enzymes in treatments 3 and 4 resulted in significantly lower
IVDMD than treatment 2. For corn silage making, usage of lactic acid bacterial
inoculant or fibrolytic enzymes did not resulted in better silage quality than the
control. Dairy goat lactation studies showed no difference of DM intake (1837,
1743, 1817, 1834 g/day), 4%FCM (1826, 1804, 1549, 1724 g/day) or apparent NDF
digestibility(77, 79, 76, 77%) among treatment groups for matured Napier grass
silages. Dairy goats fed less matured Napier grass silages had similar response as
those fed matured Napier grass silages. For the matured corn silage, dairy goat
lactation study showed no significant difference of DM intake (1142, 1039, 1096,
1103 g/day), 4%FCM (1744, 1501, 1665, 1706 g/day) and apparent NDF digestibility
(56, 56, 51, 41%). For less matured corn silage, lactation study showed no
significant difference of DM intake (1175, 1294, 1187, 1328 g/day) and 4%FCM
(1665, 1340, 1811, 1779 g/day). In conclusion, lactic acid bacterial inoculant could
improve the silage quality of Napier grass, but had no benefit toward corn silage
quality. Application of fibrolytic enzymes in addition to lactic acid bacterial
inoculant could not further improve fiber digestibility for both Napier grass and corn
silages.
