Dear M.Vasim,
For 100 goats you requires 4000sqft of hard land for shed,and 5 acres of fertile land to cultivate and feed 100 goats and their kids through out the year.The cost required depends on the cost of breed in your area.Bank provides loan only after having security of enough property like land or building.so if you have enough amount of secuirity and good relations with bank,then any nationalized bank provides you the loan for goat farming.After getting the loan you can apply to NABARD for 25% subsidy,but main condition of NABARD is that you must avail the loan from any nationalized bank.
Regards,
