FODDER PRODUCTION THROUGH AGROFORESTRY:
A Boon For Profitable Sheep And Goat Farming

AGROFORESTRY-TREE LEAVESTrees and shrubs - nutrients for grazing animals, especially pronounced dry season.
Browse or top-feed
Goats preferred top feeds better compared to sheep.
Tannin rich tree leaves - modulating the ruminal microbial population, improves nitrogen and reduces the methane production.
Agroforestry systems could be effectively utilized for fodder production vis-à-vis livestock production - environmentally safe system of land use.

AGRISILVI FODDER PRODUCTION SYSTEM
• Yielded 12% higher dry biomass and 34% digestible nutrients
• Could be fed to sheep (70 lambs/ha) instead of concentrate
feed to curtail the feed cost

SILVIPASTORAL SYSTEM
• Dry fodder biomass yield from 1.25 - 4.50 tons (natural pasture) to 4.50 – 8.70 tons / ha / year.
• Silvipasture with Leucena leucocephala + Gliricidia sepium + Albizia lebbeck as tree components and Cenchrus ciliaris + Stylosanthes scabra as pasture components was recommended for greening of wastelands in rain fed condition

• The tree fodder available from agriculture land of same unit area will be utilized for feeding animals to attain higher benefit per unit area.
• Fodder trees provide a cheap protein, energy, minerals and vitamins for livestock fed on low quality roughages or grasses and reduced the cost of feeding.
• Fodder production through agroforestry systems could be popularized for profitable eco-friendly livestock production.
