    IN VITRO EVALUATION OF LABORATORY SILAGES OF SUPER NAPIER AND MAIZE FODDERS WITH Stylosanthes hamata AND Melia dubia

    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. Keywords: Proximate principles, digestibility, In vitro gas production and volatile fatty acid profile.
