Abstract
A study was conducted for In vitro evaluation of laboratory silages of Super
Napier (SN) and Maize fodder with Stylosanthes hamata (SH) and Melia dubia (MD). In
the present trial, the fresh fodder and laboratory silages were made in combination of
cereal fodder - Maize or Super Napier (70, 80 and 90 per cent) with legume fodders – SH
or MD (30, 20 and 10 per cent), respectively. Comparison was made between and within
the fresh and silage fodder in all combination for physical properties, proximate
principles, digestibility, In vitro gas production and volatile fatty acid profile. Results
showed sweet smell, no fungal growth, golden yellow and greenish yellow colour were
the physical properties of silages prepared. In both fresh fodder and silage, 30% of
legume inclusion to SN resulted in significantly (P<0.05) higher crude protein and total
ash content, but there was no effect on ether extract. True Dry Matter Digestibility
(TDMD) and Neutral Detergent Fibre Digestibility (NDFD) were significantly (P<0.05)
higher in both fresh fodder and silage of Maize mixed with 30% legume compared to
other combinations. Legume inclusion to Maize fodder at 10% found to be having
significantly (P<0.05) higher ME level. Gas production was significantly (P<0.05) higher
in MD at 10% inclusion with Maize fodder. TVFA in both fresh fodder and silages were
significantly (P<0.05) higher in 30% inclusion of legume with SN. Molar concentration
of acetate was found to be higher in 10% combination of legume with Maize whereas
propionate and butyrate were significantly (P<0.05) higher at 30% inclusion of legume to
Maize. The results indicated that to obtain optimum levels of both energy and proteins in
the diet/fodders/silages, the percentages of non-legumes and legumes can be restricted to
85 and 15% respectively. Further inclusion of legumes with non-legume fodders was
found to be more ideal and can be recommended to dairy farmers to overcome the
malnourishment in livestock in general.
