Three on farm experiments – experiment 1 (E1, 130 days), experiment 2 (E2, 120 days) and
experiment 3 (E3, 120 days) were carried to evaluate the performance of Nellore Zodpi ram
lambs grazed in established hortipastoral systems (mango and sweet orange orchards of above 5
years old with natural and established pasture of C. ciliaris, S. hamata and with boundary
plantation of L. leucocephala) in rainfed areas. The forage and crude protein (CP) yields (t ha-1)
were significantly (P < 0.01) higher from established pasture than natural pasture in orchards.
The established pasture contained medium (C. ciliaris) to high (S. hamata) CP and medium in
vitro dry matter degradability (IVDMD), where as the natural pasture contained low CP and
medium IVDMD. The lambs with supplementary grazing on established pasture or supplemented
with L. leucocephala foliage gained significantly (P < 0.01) higher live weight than grazed
solely on natural pasture in all the experiments. Similarly higher (P < 0.01) average daily gain
(ADG) was also observed with supplementary grazing. Income from ram lamb production under
hortipastoral systems seems to be quite remunerative in all the experiments. Net gain ($ ha-1)
from the hortipastoral systems ranged from 40.4 to 70.1 through ram lamb production. Further,
higher income was observed with supplementary grazing on established pasture or
supplementation of L. leucocephala foliage. The present study reveals that the orchards (mango
and sweet orange) over 5 years old can be developed as hortipastoral systems with suitable
understory grass species and boundary plantation of L leucocephala for higher biomass
production. These systems can be efficiently integrated for ram lamb production in rainfed
areas. Season plays a lot in availability of nutrients and subsequently the growth of the ram
lambs under hortipastoral systems in rainfed areas, hence the lambs could be introduced
preferably in the middle of rainy season (September month) for maximum weight gain.
