Hai Kumaresan, I'm Mr. Kantharaj from Bangalore, an " Organic enthusiast ". As you have 2 acres, go for 5 cows & have goats and sheep 10+1 ratio for both, under Stall Fed Method. You will have minimum 1.5 acres for fodder crops, sufficient for all. Send your email to me - jkantharaj6@gmail.com if interested.
