Dear Prashant,
If you wont have nay intention of breeding goats for meat or milk then why you want to keep (breed) the goats,just for manure?If you want only manure,then just buy the manure it will be more cheaper for you rather than breeding goats only for manure.If still you want to breed goats then-
1.Osmanabadi adult goats are best for manure,you can buy old goats who cant breed further as you don’t want their kids or milk.They will come in half of price as compare to young or breeding goats.
2.To supply manure to 10 acres of land once in a year you requires 50 goats.
3.You can buy female goats of age around 8yrs to get only manure from them.Buying of female goats of older age will be cheaper as compare to male goats.
4.You have to expense on their green fodder only,each goat will eat around 6%-10% of live body weight.Old age goats will be around 40kg-50kg.So you requires daily 4kg-5kg of green fodder for each goats.This green fodder can be cultivated in one acre of farm land.You requires one liter of water per day per goat in summer and 200ml in winter and 100ml in rainy season,goats drink very little water.They requires simple accommodation,shed roof with tin metal and flooring of hard rock.
5.Yes you can loose the goats.Your farm should be fence from all sides.If crops are at lower places,where their head reaches easily,then they will destroy it by eating.No,there is no thread among themselves except dog,dog should be familiar,means he should not bite the goats otherwise they will get scared.
6.You can buy thee goats from our farm and also manure but in little quantity as we utilize manure in our farm too,for address visit our websites link-http://goatfarm.co.in/contact-us/
7.Usual life span of goats is around 15yrs.Yes they needs vaccination every year.Vaccinations are easily available in every Govt. animal husbandry clinic.
