  • Biomass yield and carrying capacity to hold different livestock species under various agroforestry models were arrived with different fodder crops to augment fodder production and productivity in animals.
  • Urea treated Complete feed block has been prepared for economic feeding of low yielding animals.
  • New fodder varieties such as Bajra – Napier hybrid grass Co(BN)5, Fodder Sorghum Co31 and Fodder Cowpea Co(FC)8 were evaluated for ruminants.
  • Unconventional feed resources like Samai, Varagu, Soybean hulls, Mango-peel waste, Tapioca thippi and animal organic wastes were evaluated for ruminants.
  • Top feed resources like Subabul (Leucaena leucocephala), Vagai (Albizzia lebbek), Peepal (Ficus religiosa), Banyan (Ficus bengalensis), Gliricidia sepium, Othiyan (Lannea coromadelica), Jack (Artocarpus heterophyllus) and Indian cork (Millingtonia hortensis) tree leaves were evaluated for dairy animals and small ruminants.
